Hey Jude - Beatles

Hey Jude don't make it bad

Take a sad song and make it better

Remember to let her into your heart

Then you can start to make it better

Hey Jude don't be afraid

You were made to go out and get her

The minute you let her under your skin

Then you begin to make it better

And anytime you feel the pain hey Jude refrain

Don't carry the world upon your shoulders

For well you know that it's a fool who plays it cool

By making his world a little colder

Na na na na na na na na na

Hey Jude don't let me down

You have found her now go and get her

Remember to let her into your heart

Then you can start to make it better

So let it out and let it in hey Jude begin

You're waiting for someone to perform with

And don't you know that it's just you hey Jude you'll do

The movement you need is on your shoulder

Na na na na na na na na na

Hey Jude don't make it bad

Take a sad song and make it better

Remember to let her under your skin

Then you'll begin to make it

Better better better better better better oh

Na na na na na na na na na na na hey Jude

下午开学了。

锐评 yspm

主动要求被锐评的是什么心态，我不好说。但似乎这种现象屡屡发生，无法获知其目的与博取某些事物是否相关。

不清楚课程安排是怎样的，但在周日凌晨做周六的承诺像是下达了无关紧要的最后通牒。

做了多校专题训练的题单，基础算法开幕 CodeForces *3000。

Talking to the Moon - Bruno Mars

I know you're somewhere out there

Somewhere far away

I want you back

I want you back

My neighbours think I'm crazy

But they don't understand

You're all I have

You're all I have

At night when the stars light on my room

I sit by myself

Talking to the Moon

Try to get to You

In hopes your on the other side talking to me too

Oh Am I a fool, Who sits alone

Talking to the moon

I'm feeling like I'm famous

The talk of the town

They say I've gone mad

Yeah I've gone mad

But they don't know what I know

Cause when the sun goes down

Someone's talking back

Yeah they're talking back

At night when the stars light on my room

I sit by myself

Talking to the Moon

Try to get to You

In hopes your on the other side talking to me too

Oh Am I a fool, Who sits alone

Talking to the moon

(Ahh...Ahh...Ahh..)

Do you ever hear me calling

Ho Hou Ho ho Hou

'Cause every nightI'm Talking to the Moon

Still try to get to You

In hopes your on the other side talking to me too

Oh Am I a fool, Who sits alone talking to the moon

Ohoooo...

I know you're somewhere out there

Somewhere far away

早晨写了 C，尝试二分答案+二分图匹配，T 了。

上午考了模拟赛，T1 贪心错了，喜提 \(0\) 分，后面三题拼了 \(120\)，考得不行。

模拟赛途中电脑死机了。

下午回来电脑又死机了。

把题改了。

晚上吃饭看见了 lyin, bikuhiku, BrokenEclipse, zascdn。

T3 \(P=2\) 证明还是不太懂啊，吃完饭又想了想自己的方法。

但是还没想明白。

卡 C 的常也卡不过去。

稻香 - 周杰伦

对这个世界 如果你有太多的抱怨

跌倒了 就不敢继续往前走

为什么 人要这么的脆弱 堕落

请你打开电视看看

多少人 为生命在努力勇敢的走下去

我们是不是该知足

珍惜一切 就算没有拥有

还记得 你说家是唯一的城堡

随着稻香 河流继续奔跑

微微笑 小时候的梦我知道

不要哭 让萤火虫带着你逃跑

乡间的歌谣 永远的依靠

回家吧 回到最初的美好

不要这么容易 就想放弃

就像我说的

追不到的梦想 换个梦不就得了

为自己的人生鲜艳上色

先把爱涂上喜欢的颜色

笑一个吧 功成名就不是目的

让自己快乐快乐 这才叫做意义

童年的纸飞机

现在终于飞回我手里

所谓的那快乐

赤脚在田里追蜻蜓 追到累了

偷摘水果 被蜜蜂给叮到怕了

谁在偷笑呢

我靠着稻草人 吹着风 唱着歌 睡着了

哦 哦 午后吉他在虫鸣中更清脆

哦 哦 阳光洒在路上就不怕心碎

珍惜一切 就算没有拥有

还记得 你说家是唯一的城堡

随着稻香 河流继续奔跑

微微笑 小时候的梦我知道

不要哭 让萤火虫带着你逃跑

乡间的歌谣 永远的依靠

回家吧 回到最初的美好

还记得 你说家是唯一的城堡

随着稻香 河流继续奔跑

微微笑 小时候的梦我知道

不要哭 让萤火虫带着你逃跑

乡间的歌谣 永远的依靠

回家吧 回到最初的美好

早晨考虑了一下 Hall 定理，就把 C 过了。

上午打了模拟赛，T1 感觉是个奇怪东西先没管，T2 比较裸的贪心+后缀排序，中间写挂了一些，后来把二分改成复杂度正确的直接扫，然后复杂度正确的直接扫写挂了，其实这部分求个 \(height\) 数组可以更好解决。

T3 和 T4 都是暴力+特殊性质，拼了 \(100\)，感觉还行。

中午化奥同学过生日，在宿舍获取了一些蛋糕。（上边好像不是应该写在日记里的内容，所以加了这句比较日常的话）

一直在改题，T4 找了很多题解也没完全弄懂，想了一个树的证明也错了。T3 比较离谱的题，卡了半天常，xuany 重测过了。

10.4

That's Why You Go Away - Michael Learns to Rock

Baby won't you tell me why

there is sadness in your eyes

I don't wanna say goodbye to you

Love is one big illusion

I should try to forget

But there is something left in my head

You're the one who set it up

Now you're the one to make it stop

I'm the one who's feeling lost right now

Now you want me to forget every little thing you said

But there is something left in my head

I won't forget the way you're kissing

The feelings so strong were lasting for so long

But I'm not the man your heart is missing

That's why you go away I know

You were never satisfied, no matter how I tried

Now you wanna say goodbye to me

Love is one big illusion, I should try to forget

But there is something left in my head

I won't forget the way you're kissing

The feelings so strong were lasting for so long

But I'm not the man your heart is missing

That's why you go away I know

Sitting here all alone in the middle of nowhere

Don't know which way to go

There ain't so much to say now between us

There ain't so much for you

There ain't so much for me anymore

I won't forget the way you're kissing

The feelings so strong were lasting for so long

But I'm not the man your heart is missing

That's why you go away I know

That's why you go away I know

早晨学了一下反常积分的审敛法，有点纠结上一节说的“可以使用单调函数换元”的部分，上网搜了搜发现第二类换元为了找反函数是默认要单调的。

上午打了模拟赛，中间死机一次，幸亏已经交代码了。

今天这场质量一般，T1 套路题，T4 是好题，很有教育意义，但是先锋 APJifengc 最近已经做过了。

下午把题改了，然后电脑又死机了。

10.5

Say You Say Me - Lionel Richie

Say you say me

Say it for always that's the way it should be

Say you say me

Say it together naturally

I had a dream I had an awesome dream

People in the park playing games in the dark

And what they played was a masquerade

And from behind of walls of doubt a voice was crying out

Say you say me; say it for always

Thats the way it should be

Say you say me; say it together

Naturally

As we go down life's lonesome highway

Seems the hardest thing to do is to find a friend or two

A helping hand some one who understands

That when you feel you've lost your way

You've got some one there to say I'll show you

Say you say me; say it for always

Thats the way it should be

Say you say me; say it together

Naturally

So you think you know the answers oh no

'Cause the whole world has got you dancing

That's right I'm telling you

It's time to start believing oh yes

Believing who you are you are a shining star

Say you say me

Say it for always that's the way it should be

Say you say me

Say it together naturally

Say it together naturally

早晨继续看 D，昨天想了个诡异做法睡前发现第一步假了。打表看看有效的数字好像只有 \(O(m)\) 个。

上午打了场模拟赛，习惯开 int 的我在第一次测大样例不过后加了一个 1ll*，然后看了一眼好像都过了，就没管，事实是输出位置也要加，大样例输出结果中夹着一个负数。献祭 \(100\) 分。

T4 巨大插头 DP，改了一下午一晚上没改出来。

胜利是应该喜悦还是平静，失利是应该平淡还是沮丧。

波澜不惊是否过于无趣，跌宕起伏是否不够成熟。

我自己问自己。

我找不到答案。

我不需要答案。

给我一首歌的时间 - 周杰伦

雨淋湿了天空 毁得很讲究

你说你不懂 为何在这时牵手

我晒干了沉默 悔得很冲动

就算这是做错 也只是怕错过

在一起叫梦 分开了叫痛

是不是说 没有做完的梦最痛

迷路的后果 我能承受

这最后的出口 在爱过了才有

能不能给我一首歌的时间

紧紧的把那拥抱变成永远

在我的怀里你不用害怕失眠

哦 如果你想忘记我也能失忆

能不能给我一首歌的时间

把故事听到最后才说再见

你送我的眼泪 让它留在雨天

哦 越过你划的线我定了勇气 的终点

雨淋湿了天空 毁得很讲究

你说你不懂 我为何在这时牵手

我晒干了沉默 悔得很冲动

就算这是做错 也只是怕错过

在一起叫梦 分开了叫痛

是不是说 没有做完的梦最痛

迷路的后果 我能承受

这最后的出口 在爱过了才有

能不能给我一首歌的时间

紧紧的把那拥抱变成永远

在我的怀里你不用害怕失眠

哦 如果你想忘记我也能失忆

能不能给我一首歌的时间

把故事听到最后才说再见

你送我的眼泪 让它留在雨天

哦 越过你划的线我定了勇气 的终点

哦 你说我不该不该

不该在这时候说了我爱你

要怎么证明我没有说谎的力气

哦 请告诉我 暂停算不算放弃

我只有一天的回忆

能不能给我一首歌的时间

紧紧的把那拥抱变成永远

在我的怀里你不用害怕失眠

哦 如果你想忘记我也能失忆

能不能给我一首歌的时间

哦 把故事听到最后才说再见

你送我的眼泪 让它留在雨天

哦 越过你划的线我定了勇气 的终点

你说我不该不该

不该在这时说了爱你

要怎么证明我没力气

告诉我暂停算不算放弃

你说我不该不该

不该在这时才说爱你

要怎么证明我没有力气

我只有一天的回忆

早晨终于把 T4 改出来了。

上午模拟赛，T2 不会，然后打表，然后找规律推推式子过了。

T4 太难，改个 \(48\) 跑路了。

D 鉴定为不可做题了，E 是平凡树哈希换根模板。

Lose Yourself - Eminem

Look, if you had one shot, or one opportunity

To seize everything you ever wanted in one moment

Would you capture it or just let it slip?

Yo

His palms are sweaty, knees weak, arms are heavy

There's vomit on his sweater already, mom's spaghetti

He's nervous, but on the surface he looks calm and ready

To drop bombs, but he keeps on forgettin

What he wrote down, the whole crowd goes so loud

He opens his mouth, but the words won't come out

He's chokin, how everybody's jokin now

The clock's run out, time's up over, bloah!

Snap back to reality, Oh there goes gravity

Oh, there goes Rabbit, he choked

He's so mad, but he won't give up that

Is he? No

He won't have it, he knows his whole back city's ropes

It don't matter, he's dope

He knows that, but he's broke

He's so stacked that he knows

When he goes back to his mobile home, that's when it's

Back to the lab again yo

This whole rhapsody

He better go capture this moment and hope it don't pass him

You better lose yourself in the music, the moment

You own it, you better never let it go

You only get one shot, do not miss your chance to blow

This opportunity comes once in a lifetime yo

You better lose yourself in the music, the moment

You own it, you better never let it go

You only get one shot, do not miss your chance to blow

This opportunity comes once in a lifetime yo

The soul's escaping, through this hole that it's gaping

This world is mine for the taking

Make me king, as we move toward a, new world order

A normal life is borin, but superstardom's close to post mortar

It only grows harder, only grows hotter

He blows us all over these hoes is all on him

Coast to coast shows, he's know as the globetrotter

Lonely roads, God only knows

He's grown farther from home, he's no father

He goes home and barely knows his own daughter

But hold your nose cuz here goes the cold water

These hoes don' t want him no mo', he' s cold product

They moved on to the next schmoe who flows

He nose dove and sold nada

So the soap opera is told and unfolds

I suppose it's old potna, but the beat goes on

Da da dum da dum da da

You better lose yourself in the music, the moment

You own it, you better never let it go

You only get one shot, do not miss your chance to blow

This opportunity comes once in a lifetime yo

You better lose yourself in the music, the moment

You own it, you better never let it go

You only get one shot, do not miss your chance to blow

This opportunity comes once in a lifetime yo

No more games, I'ma change what you call rage

Tear this mothafuckin roof off like 2 dogs caged

I was playin in the beginnin, the mood all changed

I been chewed up and spit out and booed off stage

But I kept rhymin and stepwritin the next cypher

Best believe somebody's payin the pied piper

All the pain inside amplified by the fact

That I can't get by with my 9 to 5

And I can't provide the right type of life for my family

Cuz man, these goddam food stamps don't buy diapers

And it's no movie, there's no Mekhi Phifer, this is my life

And these times are so hard and it's getting even harder

Tryin to feed and water my seed, plus

See dishonor caught up bein a father and a prima donna

Baby mama drama's screamin on and

Too much for me to wanna

Stay in one spot, another jam or not

Has gotten me to the point, I'm like a snail

I've got to formulate a plot fore I end up in jail or shot

Success is my only mothafuckin option, failure's not

Mom, I love you, but this trail has got to go

I cannot grow old in Salem's lot

So here I go is my shot

Feet fail me not cuz maybe the only opportunity that I got

You better lose yourself in the music, the moment

You own it, you better never let it go

You only get one shot, do not miss your chance to blow

This opportunity comes once in a lifetime yo

You better lose yourself in the music, the moment

You own it, you better never let it go

You only get one shot, do not miss your chance to blow

This opportunity comes once in a lifetime yo

You can do anything you set your mind to, man

早晨以为没有模拟赛，事实是水哥模拟赛权限设错了，大家都看不见，被背刺了。

然后就出现了识别不出原题怒写点分治 NTT 挂分。

下午改了 T4，Ynoi2077 确实是比较有教育意义的复杂度优化方法，写得 \(O(n)\) 空间复杂度做法，需要长剖 \(O(\sqrt{n})\) 次，常数很大，晚上换了个长剖阈值过了。

晚上打算打 ABC。

F 是巨大分类讨论题，对称过去就变成只有两种情况了，G 把转化后的题意读给 APJifengc，被告知是求 \(\mathrm{det}(A+Bz)\)，不会矩阵树定理所以摆了。

终于上 1 Dan 了！

晴天 - 周杰伦

故事的小黄花 从出生那年就飘着

童年的荡秋千 随记忆一直晃到现在

Re So So Si Do Si La

So La Si Si Si Si La Si La So

吹着前奏 望着天空

我想起花瓣试着掉落

为你翘课的那一天 花落的那一天

教室的那一间 我怎么看不见

消失的下雨天 我好想再淋一遍

没想到 失去的勇气我还留着

好想再问一遍 你会等待还是离开

刮风这天 我试过握着你手

但偏偏 雨渐渐 大到我看你不见

还要多久 我才能在你身边

等到放晴的那天 也许我会比较好一点

从前从前 有个人爱你很久

但偏偏 风渐渐 把距离吹得好远

好不容易 又能再多爱一天

但故事的最后

你好像还是说了 拜拜

为你翘课的那一天 花落的那一天

教室的那一间 我怎么看不见

消失的下雨天 我好想再淋一遍

没想到 失去的勇气我还留着

好想再问一遍 你会等待还是离开

刮风这天 我试过握着你手

但偏偏 雨渐渐 大到我看你不见

还要多久 我才能在你身边

等到放晴的那天 也许我会比较好一点

从前从前 有个人爱你很久

偏偏 风渐渐 把距离吹得好远

好不容易 又能再多爱一天

但故事的最后

你好像还是说了 拜拜

刮风这天 我试过握着你手

但偏偏 雨渐渐 大到我看你不见

还要多久 我才能够在你身边

等到放晴那天 也许我会比较好一点

从前从前 有个人爱你很久

但偏偏 雨渐渐 把距离吹得好远

好不容易 又能再多爱一天

但故事的最后

你好像还是说了拜

今天没有模拟赛。

上午做了 F 和 H，F 用直径的性质就很简单了，H 交互不会。

下午被人喊来看之前 xuany 场的 T4，编了个看着有点道理的做法，5k 疯狂提问，我疯狂拒绝。

下午打了 CF，前面都比较简单，但是也爆了几发罚时，E 弄了半天终于调出来了，赢。同机房几个同学没调出来，比较可惜啊。

然后 D FST 了，输。原因好像是 \(a_i\) 可以为 \(0\)，有可能会出错，然后 Pretest 里没有这种情况。

好不容易打得不错的一场 CF 也给弄废了，\(50\) 变 \(800\) 了，过了 E 还没 D 分高。

月底还有两场，在 CSP 后面，希望能打。

Further on up the Road - Johnny Cash

Where the road is dark and the seed is sowed

Where the gun is cocked and the bullet's cold

Where the miles are marked in the blood and gold

I'll meet you further on up the road

Got on my dead man's suit and my smilin' skull ring

My lucky graveyard boots and a song to sing

I got a song to sing it keeps me out of the cold

And I'll meet you further on up the road

Further on up the road

Further on up the road

Where the way is dark and the night is cold

One sunny mornin' we'll rise I know

And I'll meet you further on up the road

Now I been out in the desert just doin' my time

Searchin' through the dust lookin' for a sign

If there's a light up ahead well brother I don't know

But I got this fever burnin' in my soul

Further on up the road

Further on up the road

Further on up the road

Further on up the road

One sunny mornin' we'll rise I know

And I'll meet you further on up the road

上午打了模拟赛，感觉还行，但是考完看不了榜有点恼。

下午改完题弄了个一言功能。

晚上做了做总习题五，放缩还是不大会，后面咋让证明柯西-施瓦茨不等式？

I Want to Break Free - Queen

I want to break free

I want to break free

I want to break free from your lies

You're so self satisfied I don't need you

I've got to break free

God knows, God knows I want to break free

I've fallen in love

I've fallen in love for the first time

And this time I know it's for real

I've fallen in love yeah

God knows God knows I've fallen in love

It's strange but it's true

I can't get over the way you love me like you do

But I have to be sure

When I walk out that door

Oh how I want to be free baby

Oh how I want to be free

Oh how I want to break free

But life still goes on

I can't get used to living without living without

Living without you by my side

I don't want to live alone hey

God knows got to make it on my own

So baby can't you see

I've got to break free

I've got to break free

I want to break free yeah

I want, I want, I want, I want to break free

上午打了模拟赛，改了一天题，后两题质量很高。

继续做总习题五，\(\int_0^{\frac{\pi}{4}} \ln(1+\tan x)\mathrm{d}x=\frac{\pi}{8}\ln 2\)，牛牛牛。

Hammer to Fall - Queen

Here we stand or here we fall

History won't care at all

Make the bed, light the light

Lady Mercy won't be home tonight

You don't waste no time at all

Don't hear the bell but you answer the call

It comes to you as to us all

We're just waiting

For the hammer to fall

Oh every night and every day

A little piece of you is falling away

But lift your face, the Western Way

Build your muscles as your body decays

Toe your line and play the game

Let the anaesthetic cover it all

Till one day they call your name

You know it's time for the hammer to fall

Rich or poor or famous for

Your trouth is all the same

Lock your door but the rain is pouring

Through your window pane

Baby now your struggle's all in vain

For we who grow up tall and proud

In the shadow of the Mushroom Cloud

Convinced our voice can't be heard

We just wanna scream it louder and louder

What the hell we fighting for?

Just surrender and it won't hurt at all

You just got time to say your prayers

While you're waiting the hammer to fall

上午打了模拟赛，不会找环，不会观察性质，不会超级钢琴。

下午改了题，然后忘了乙醇乙醛乙酸的转化了。

晚上积分。题做完了，后面应用和微分方程就先等等，高数告一段落了，后面可能看看线代学矩阵树定理。

When I Was Your Man - Bruno Mars

Same bed but it feels just a little bit bigger now

Our song on the radio but it don´t sound the same

When our friends talk about you

All that it does is just tear me down

Cause my heart breaks a little when I hear your name

And it all just sound like uh uh uh

Hmmm too young too dumb to realize

That I should have bought you flowers and held your hand

Should have gave you all my hours when I had the chance

Take you to every party

Cause all you wanted to do was dance

Now my baby is dancing

But she´s dancing with another man

My pride my ego my needs and my selfish ways

Caused a good strong woman like you to walk out my life

Now I never never get to clean up the mess I made

And it haunts me every time I close my eyes

It all just sounds like uh uh uh uh

Too young too dumb to realize

That I should have bought you flowers and held your hand

Should have gave all my hours when I had the chance

Take you to every party

Cause all you wanted to do was dance

Now my baby is dancing

But she´s dancing with another man

Although it hurts I´ll be the first to say that I was wrong

Oh I know I´m probably much too late

To try and apologize for my mistakes

But I just want you to know

I hope he buys you flowers I hope he holds your hand

Give you all his hours when he has the chance

Take you to every party

Cause I remember how much you loved to dance

Do all the things I should have done when I was your man

Do all the things I should have done when I was your man

上午模拟赛，下午学会了一个 Boruvka 求最小生成树感觉很有用。

写一下 G。

体活去打球。

晚上把 G 过了，“基础算法”除了那个诡异 D 都做完了，然后是 DP。

Somebody to Love - Queen

Can anybody find me somebody to love

Each morning I get up I die a little

南山南 - 马頔

你在南方的艳阳里 大雪纷飞

我在北方的寒夜里 四季如春

如果天黑之前来得及

我要忘了你的眼睛

穷极一生 做不完一场梦

他不再和谁谈论相逢的孤岛

因为心里早已荒无人烟

他的心里再装不下一个家

做一个只对自己说谎的哑巴

他说你任何为人称道的美丽

不及他第一次遇见你

时光苟延残喘无可奈何

如果所有土地连在一起

走上一生只为拥抱你

喝醉了他的梦 晚安

他听见有人唱着古老的歌

唱着今天还在远方发生的

就在他眼睛里看到的孤岛

没有悲伤但也没有花朵

你在南方的艳阳里 大雪纷飞

我在北方的寒夜里 四季如春

如果天黑之前来得及

我要忘了你的眼睛

穷极一生 做不完一场梦

你在南方的艳阳里 大雪纷飞

我在北方的寒夜里 四季如春

如果天黑之前来得及

我要忘了你的眼睛

穷极一生 做不完一场梦

大梦初醒 荒唐了一生

南山南 北秋悲

南山有谷堆

南风喃 北海北

北海有墓碑

南山南 北秋悲

Viva la Vida - Coldplay

I used to rule the world

Seas would rise when I gave the word

Now in the morning I sleep alone

Sweep the streets I used to own

I used to roll the dice

Feel the fear in my enemy's eyes

Listen as the crowd would sing:

"Now the old king is dead

Long live the king "

One minute I held the key

Next the walls were closed on me

And I discovered that my castles stand

Upon pillars of salt and pillars of sand

I hear Jerusalem bells are ringing

Roman Cavalry choirs are singing

Be my mirror my sword and shield

My missionaries in a foreign field

For some reason I can't explain

Once you go there was never

Never an honest word

That was when I ruled the world

It was the wicked and wild wind

Blew down the doors to let me in

Shattered windows and the sound of drums

People couldn't believe what I'd become

Revolutionaries wait

For my head on a silver plate

Just a puppet on a lonely string

Oh who would ever wanna be king

I hear Jerusalem bells are ringing

Roman Cavalry choirs are singing

Be my mirror my sword and shield

My missionaries in a foreign field

For some reason I can't explain

I know Saint Peter won't call my name

Never an honest word

But that was when I ruled the world

(Ohhhhh Ohhh Ohhh)

Hear Jerusalem bells are ringing

Roman Cavalry choirs are singing

Be my mirror my sword and shield

My missionaries in a foreign field

For some reason I can't explain

I know Saint Peter won't call my name

Never an honest word

But that was when I ruled the world

早晨打球。

回机房把 DP 的 A 做了，然后上午高校校园行，去了 PKU。

晚上有 ARC，希望不要掉回 1 Kyu。

早晨打球没吃饭，中午吃得还行，然后晚上感觉不是很饿就没吃，中午起来有点发懵，头疼，还是得规律作息，晚上盖厚被子了。

列车总会到站，希望你珍惜旅途中的时光。——yspm

没下分。

Take Me to Your Heart - Michael Learns to Rock

Hiding from the rain and snow

Trying to forget but I won't let go

Looking at a crowded street

Listening to my own heart beat

So many people all around the world

Tell me where do I find someone like you girl

Take me to your heart take me to your soul

Give me your hand before I'm old

Show me what love is - haven't got a clue

Show me that wonders can be true

They say nothing lasts forever

We're only here today

Love is now or never

Bring me far away

Take me to your heart take me to your soul

Give me your hand and hold me

Show me what love is - be my guiding star

It's easy take me to your heart

Standing on a mountain high

Looking at the moon through a clear blue sky

I should go and see some friends

But they don't really comprehend

Don't need too much talking without saying anything

All I need is someone who makes me wanna sing

Take me to your heart take me to your soul

Give me your hand before I'm old

Show me what love is - haven't got a clue

Show me that wonders can be true

They say nothing lasts forever

We're only here today

Love is now or never

Bring me far away

Take me to your heart take me to your soul

Give me your hand and hold me

Show me what love is - be my guiding star

It's easy take me to your heart

Take me to your heart take me to your soul

Give me your hand and hold me

Show me what love is - be my guiding star

It's easy take me to your heart

早晨起来感觉好点。

上午打模拟赛了，T3 非常好题目，T4 差点做出来比较遗憾。

看了看线代，感觉可以去学矩阵树了。

但是求行列式只能瞎求，消元也做不到巧妙。

现在差两场 CF 和一场 ARC 没改，然后还有半套 Universal Cup 和一些专题训练没写，To Do List 越来越长了。啥时候做呢？不知道。

突然好想你 - 五月天

最怕空气突然安静

最怕朋友突然的关心

最怕回忆 突然翻滚绞痛着 不平息

最怕突然 听到你的消息

想念如果会有声音

不愿那是悲伤的哭泣

事到如今 终于让自己属于 我自己

只剩眼泪 还骗不过自己

突然好想你 你会在哪里

过得快乐或委屈

突然好想你 突然锋利的回忆

突然模糊的眼睛

我们像一首最美丽的歌曲

变成两部悲伤的电影

为什么你 带我走过最难忘的旅行

然后留下 最痛的纪念品

我们 那么甜那么美那么相信

那么疯那么热烈的 曾经

为何我们

还是要奔向各自的幸福和遗憾中老去

突然好想你 你会在哪里

过得快乐或委屈

突然好想你 突然锋利的回忆

突然模糊的眼睛

最怕空气突然安静

最怕朋友突然的关心

最怕回忆 突然翻滚绞痛着 不平息

最怕突然 听到你的消息

最怕此生 已经决心自己过 没有你

却又突然 听到你的消息

上午打了模拟赛，T3 假了，寄了。

下午改完题，打算开始写板子了。

写了发 EXCRT，理所应当写错了，然后改对了。

然后写了点别的感觉还行。

可惜没如果 - 林俊杰

假如把犯得起的错

能错的都错过

应该还来得及去悔过

假如没把一切说破

那一场小风波 将一笑带过

在感情面前 讲什么自我

要得过且过 才好过

全都怪我

不该沉默时沉默 该勇敢时软弱

如果不是我

误会自己洒脱 让我们难过

可当初的你 和现在的我

假如重来过

倘若那天

把该说的话好好说

该体谅的不执着

如果那天我

不受情绪挑拨

你会怎么做

那么多如果 可能如果我

可惜没如果 只剩下结果

如果早点了解

那率性的你

或者晚一点

遇上成熟的我

不过 oh

全都怪我

不该沉默时沉默 该勇敢时软弱

如果不是我

误会自己洒脱 让我们难过

可当初的你 和现在的我

假如重来过

倘若那天

把该说的话好好说

该体谅的不执着

如果那天我

不受情绪挑拨

你会怎么做

那么多如果 可能如果我

可惜没如果 没有你和我

都怪我

不该沉默时沉默 该勇敢时软弱

如果不是我

误会自己洒脱 让我们难过

可当初的你 和现在的我

假如重来过

倘若那天

把该说的话好好说

该体谅的不执着

如果那天我

不受情绪挑拨

你会怎么做

那么多如果 可能如果我

可惜没如果

只剩下结果

可惜没如果

上午考模拟赛，T4 Slope Trick，不会。

明天怎么还有模拟赛！恼了！

决定先写板子，有时间再改。

把有用的数学板子写完了，原根不会。

江南 - 林俊杰

风到这里就是粘

粘住过客的思念

雨到了这里缠成线

缠着我们流连人世间

你在身边就是缘

缘分写在三生石上面

爱有万分之一甜

宁愿我就葬在这一点

圈圈圆圆圈圈

天天年年天天 的我

深深看你的脸

生气的温柔

埋怨的温柔 的脸

不懂爱恨情愁煎熬的我们

都以为相爱就像风云的善变

相信爱一天 抵过永远

在这一刹那冻结了时间

不懂怎么表现温柔的我们

还以为殉情只是古老的传言

离愁能有多痛 痛有多浓

当梦被埋在江南烟雨中

心碎了才懂

圈圈圆圆圈圈

天天年年天天 的我

深深看你的脸

生气的温柔

埋怨的温柔 的脸

不懂爱恨情愁煎熬的我们

都以为相爱就像风云的善变

相信爱一天 抵过永远

在这一刹那冻结了时间

不懂怎么表现温柔的我们

还以为殉情只是古老的传言

离愁能有多痛 痛有多浓

当梦被埋在江南烟雨中

心碎了才懂

相信爱一天 抵过永远

在这一刹那冻结了时间

不懂怎么表现温柔的我们

还以为殉情只是古老的传言

离愁能有多痛 痛有多浓

当梦被埋在江南烟雨中

心碎了才懂

上午模拟赛，写完前两题和部分分就开摆了。

改完题开始写板子，图论剩一个静态仙人掌先咕了。

字符串感觉还行。

Just the Way You are - Bruno Mars

Oh her eyes, her eyes

Make the stars look like they're not shining

Her hair, her hair

Falls perfectly without her trying

She's so beautiful

And I tell her every day

Yeah I know, I know

When I compliment her

She won’t believe me

And it’s so, it’s so

Sad to think that she don't see what I see

But every time she asks me do I look okay

I say

When I see your face

There's not a thing that I would change

Cause you're amazing

Just the way you are

And when you smile

The whole world stops and stares for a while

Cause girl you're amazing

Just the way you are

Her lips, her lips

I could kiss them all day if she'd let me

Her laugh, her laugh

She hates but I think it’s so sexy

She's so beautiful

And I tell her every day

Oh you know, you know, you know

I’d never ask you to change

If perfect is what you're searching for

Then just stay the same

So don't even bother asking

If you look okay

You know I will say

When I see your face

There's not a thing that I would change

Cause you're amazing

Just the way you are

And when you smile

The whole world stops and stares for a while

Cause girl you're amazing

Just the way you are

The way you are

The way you are

Girl you're amazing

Just the way you are

When I see your face

There's not a thing that I would change

Cause you're amazing

Just the way you are

And when you smile

The whole world stops and stares for a while

Cause girl you're amazing

Just the way you are

上午写了发李超线段树，然后就出发了。

路上网一般，手机看了看柯南。

到酒店发了蛋糕，感觉还行。

We are the World - U.S.A. for Africa

There comes a time when we heed a certain call

When the world must come together as one

There are people dying

And it's time to lend a hand to life

The greatest gift of all

We can't go on pretending day by day

That someone, somewhere will soon make a change

We are all a part of God's great big family

And the truth, you know

Love is all we need

We are the world, we are the children

We are the ones who make a brighter day

So let's start giving

There's a choice we're making

We're saving our own lives

It's true we'll make a better day

Just you and me

Send them your heart so they'll know that someone cares

And their lives will be stronger and free

As God has shown us by turning stone to bread

And so we all must lend a helping hand

We are the world, we are the children

We are the ones who make a brighter day

So let's start giving

There's a choice we're making

We're saving our own lives

It's true we'll make a better day

Just you and me

When you're down and out, there seems no hope at all

But if you just believe there's no way we can fall

Well well well

Let's realize that a change can only come

When we stand together as one

We are the world, we are the children

We are the ones who make a brighter day

So let's start giving

There's a choice we're making

We're saving our own lives

It's true we'll make a better day

Just you and me

We are the world, we are the children

We are the ones who make a brighter day

上午写了个平衡树。

中午起来又看了看树上 DDP。

开考了。

T1 比较简单，T2 想了想感觉回了，然后假了，然后一直会但是一直不过大样例也不过拍。

两个多小时就决定去写 T3 了，加了个哈希调了一会儿过大样例了就没管。剩下 20 分钟只够给 T2 补一个暴力了。

出来自测发现 T3 挂了，得分随机。

第五次参加 CSP，第五次考拉胯。按照之前模拟赛的经验，感觉这套题理想状态下拿到 \(300\) 以及 T4 的部分分是有希望的。事实是 T2 开始想得太简单浪费很多时间以及最后没做出来引发后面的事故。某种意义上写 T3 的心态还算平稳，能过大样例就比没调出来要强。

如果是 NOIP 就几乎宣告退役了，由实力和运气双双不济导致的。

感觉做题策略是不算下下策，确实觉得在更早的时间点去做 T3 而不是改 T2 得不到什么更好的收益。

那就这样了，NOIP 不到还剩一个月。

倔强 - 五月天

当 我和世界不一样

那就让我不一样

坚持对我来说就是以刚克刚

我 如果对自己妥协

如果对自己说谎

即使别人原谅

我也不能原谅

最美的愿望 一定最疯狂

我就是我自己的神

在我活的地方

我和我最后的倔强

握紧双手绝对不放

下一站是不是天堂

就算失望 不能绝望

我和我骄傲的倔强

我在风中大声地唱

这一次为自己疯狂

就这一次 我和我的倔强

对 爱我的人别紧张

我的固执很善良

我的手越肮脏

眼神越是发光

你 不在乎我的过往

看到了我的翅膀

你说被火烧过才能出现凤凰

逆风的方向

更适合飞翔

我不怕千万人阻挡

只怕自己投降

我和我最后的倔强

握紧双手绝对不放

下一站是不是天堂

就算失望 不能绝望

我和我骄傲的倔强

我在风中大声地唱

这一次为自己疯狂

就这一次 我和我的倔强

我和我最后的倔强

握紧双手绝对不放

下一站是不是天堂

就算失望 不能绝望

我和我骄傲的倔强

我在风中大声地唱

这一次为自己疯狂

啦啦啦啦啦啦啦啦

就算失望 不能绝望

啦啦啦啦啦啦啦啦

啦啦啦啦啦啦啦啦

啦啦啦啦啦啦啦啦

就这一次 我和我的倔强

开学了。

改前几天 T4，一下午一晚上没改出来。

看 UU 的 T2 题解，发现用栈判断然后哈希非常简单，完全不需要找充要条件，我太弱智了。

最长的电影 - 周杰伦

我们的开始

是很长的电影

放映了三年

我票都还留着

冰上的芭蕾

脑海中还在旋转

望着你慢慢忘记你

朦胧的时间

我们溜了多远

冰刀划的圈

圈起了谁改变

如果再重来

会不会稍嫌狼狈

爱是不是不开口才珍贵

再给我两分钟

让我把记忆结成冰

别融化了眼泪

你妆都花了

要我怎么记得

记得你叫我忘了吧

记得你叫我忘了吧

你说你会哭

不是因为在乎

朦胧的时间

我们溜了多远

冰刀划的圈

圈起了谁改变

如果再重来

会不会稍嫌狼狈

爱是不是不开口才珍贵

再给我两分钟

让我把记忆结成冰

别融化了眼泪

你妆都花了

要我怎么记得

记得你叫我忘了吧

记得你叫我忘了吧

你说你会哭

不是因为在乎

再给我两分钟

让我把记忆结成冰

记得你叫我忘了吧

你说你会哭

不是因为在乎

早晨拍那个 T4，改成 \(80\) 分了，链会挂。

上午模拟赛。

下午晚上改题，临走前 T4 改完了，喜了。

字符串专题训练前五道题分别是：SAM 上线段树合并、SA 关于 \(height\) 建 Kruskal 重构树、Palindrome Series、SAM 上线段树合并和 Manacher+NTT 字符串匹配。非常好题目。

上午模拟赛，下午改题。

对拍发现那个 T4 是 Splay 有地方没有下传标记，但是不知道是哪里。

又改了改发现是交换子树写错了，但是还是不对。

不再犹豫 - Beyond

无聊望见了犹豫

达到理想不太易

即使有信心斗志却抑止

谁人定我去或留

定我心中的宇宙

只想靠两手 向理想挥手

问句天几高 心中志比天更高

自信打不死的心态活到老

Oh…… 我有我心底故事

亲手写上每段得失乐与悲与梦儿

Oh…… 纵有创伤不退避

梦想有日达成找到心底梦想的世界

终可见

谁人没试过犹豫

达到理想不太易

即使有信心斗志却抑止

谁人定我去或留

定我心中的宇宙

只想靠两手 向理想挥手

问句天几高 心中志比天更高

自信打不死的心态活到老

Oh…… 我有我心底故事

亲手写上每段得失乐与悲与梦儿

Oh…… 纵有创伤不退避

梦想有日达成找到心底梦想的世界

终可见

Oh……

亲手写上每段得失乐与悲与梦儿

Oh……

梦想有日达成找到心底梦想的世界

终可见

改作息了。

上午模拟赛最后十分钟死机两次，ssh 配合 killall5 非常好用。

结果 T2 和 T3 爆两个 corner cases，恼了。

尝试调那个 T4，破防了，不调了。

10.27

爱与诚 - 古巨基

其实自己一个更开心

只等你讲

其实大家早已嫌大家却扮忙

恨有多一点碰撞

仍然无聊事干不敢打搅对方

要是你愿意诚实讲一趟

彼此都起码觉得释放

不要哭我也忍得了这些年来的委曲

没法真心爱下去 只好真心真意的结束

别再做情人 做只猫做只狗 不做情人

做只宠物至少可爱迷人

和你不瞅不睬最终只会成为敌人

沦为旧朋友是否又称心

没有心只像闲人

若有空难道有空可接吻

注定似过路人陌生 你怎么手震

长期被迫恋爱也真比失恋更惨

长期扮演若无其事般更困难

是我专登反应慢明明为时甚晚

牌一早该要摊

再像我伴侣仍望多一眼

一生都将会记得今晚

别再做情人 做只猫做只狗 不做情人

做只宠物至少可爱迷人

和你不瞅不睬 最终只会成为敌人

沦为旧朋友是否又称心

没有心只像闲人

若有空难道有空可接吻

这预告发自虔诚内心

对不起

自动分手错愕的你怕会伤感

麻木的我现在也可转台来贺你新生

别再做情人 做只猫做只狗 不做情人

做只宠物至少可爱迷人

和你相交不浅 无谓明日会被你憎

沦为旧朋友是否又称心

没有心只像闲人

若有空难道有空可接吻

注定似过路人陌生 你怎么手震

早晨做了字符串构造题。

上午模拟赛不咋会，写完暴力做了个数数题，比较简单。

T3 模拟费用流，T4 是个很厉害的构造，把 T4 改了，T3 只写了暴力费用流。

晚上把要做的题放在一起 shuffle 了一下，弄了个 VJduge 题单。

胸がドキドキ - THE HIGH-LOWS（《名侦探柯南》OP1）

百年ぶりの世纪末

泣けといわれて仆は笑った

ひさかたぶりの世纪末

広い世界へとび出してゆく

子供のころにわかりかけてたことが

大人になってわからないまま

えらくもないし

りっぱでもない

わかってるのは胸のドキドキ

答えでもない本当でもない

信じてるのは胸のドキドキ

胸のドキドキだけ

かっこいいかはわからないけど

おさえきれない梦をみたんだ

作戦たててじっと待つより

子供のままでぶつかってゆく

宇宙の果てに旗を立てたとしても

宇宙の谜はわからないまま

えらくもないし

りっぱでもない

わかってるのは胸のドキドキ

答えでもない本当でもない

信じてるのは胸のドキドキ

胸のドキドキ

えらくもないし

りっぱでもない

わかってるのは胸のドキドキ

答えでもない本当でもない

信じてるのは胸のドキドキ

胸のドキドキだけ

早晨做了个贪心题，有点水。

上午模拟赛，下午晚上改题。

明天没考试，计划先把昨天模拟费用流改了。

Feel Your Heart - VELVET GARDEN（《名侦探柯南》OP2）

Feel Your Heart めぐる季節の中 君への憧れが

Just My Love その想いが 見えない力くれるから

迷いも悩みもみんな まるでちっさく感じる どんな时でも

後ろ姿が少し 少し大きく見えた日 木漏れ日の中 映し出されて

見えない明日探して 手探りであせって 傷ついてしまうけど

未来は出口のない迷路 謎解きのパズルのように

奇迹は起きなくても 夢は勇気になる

Feel Your Heart めぐる季節の中 君への憧れが

Just My Love その想いが 见えない力くれるから

迷いも悩みもみんな まるでちっさく感じる どんな时でも

目にするものはいつしか 通り过ぎてゆくけど

さがしもの見つけたの？

心の中のばしたその手を 二人だけの糸のように

強く強くむすんで 永遠にいつまでも

Feel Your Heart 過ぎる時の中 君への憧れが

Just My Love 何処にいても 見えない力になるから

つらくくじけそうな日も 少しずつ愈されてく どんな時でも

Feel Your Heart それぞれの想いも これからの未来も

Just My Love いつもそばに

Feel Your Heart めぐる季節の中 君への憧れが

Just My Love その想いが 見えない力くれるから

迷いも悩みもみんな まるでちっさく感じる どんな时でも

Feel Your Heart 過ぎる時の中 君への憧れが

Just My Love 何処にいても 見えない力になるから

つらくくじけそうな日も 少しずつ愈されてく どんな時でも

Feel Your Heart めぐる季節の中

Just My Love その想いが

Feel Your Heart

早晨去打球。

上午先做了个概率期望，开始读错题假了，后来写出式子读错题假了，和题解式子差不多，\(O(n^3)\) 化简到 \(O(n)\) 实在是很厉害的操作。

然后看了个树上问题，发现是根号分治然后均摊的数据结构，中间假了几次，写了一下午才写完，然后去抱了若干 whk 资料。

由于有 whk 资料普查的剪贴板，然后发现数学生物少了，又回去找了一发，找到了。

后来 CSP 出分了，\(100+35+40+0=175\)，非常符合 T3 的挂分区间，还是挺低的，NOIP 加油吧。

Catch my Breath - Kelly Clarkson

I don't wanna be left behind

Distance was a friend of mine

Catching breath in a web of lies

I've spent most of my life

Riding waves playing acrobat

Shadowboxing the other half

Learning how to react

I've spent most of my time

Catching my breath

Letting it go

Turning my cheek for the sake of this show

Now that you know

This is my life

I won't be told what's supposed to be right

Catch my breath

No one can hold me back

I ain't got time for that

Catch my breath

Won't let them get me down

It's all so simple now

Addicted to the love I found

Heavy heart now a weightless cloud

Making time for the ones that count

I'll spend the rest of my time

Laughing hard with the windows down

Leaving footprints all over town

Keeping faith karma comes around

I will spent the rest of my life

Catching my breath

Letting it go

Turning my cheek for the sake of the show

Now that you know

This is my life

I won't be told what's supposed to be right

Catch my breath

No one can hold me back

I ain't got time for that

Catch my breath

Won't let them get me down

It's all so simple now

You helped me see

The beauty in everything

Catching my breath

Letting it go

Turning my cheek for the sake of this show

Now that you know

This is my life

I won't be told what's supposed to be right

Catching my breath

Letting it go

Turning my cheek for the sake of this show

Now that you know

This is my life

I won't be told what's supposed to be right

Catch my breath

Catch my breath

No one can hold me back

I ain't got time for that

Catch my breath

Won't let them get me down

It's all so simple now

It's all so simple now

Catching my breath

Letting it go

Turning my cheek for the sake of this show

Now that you know

This is my life

I won't be told what's supposed to be right

Catch my breath

No one can hold me back

I ain't got time for that

Catch my breath

Won't let them get me down

It's all so simple now

昨天和众人商量一下，把 STAOI 扬了，自己弄了个 λOI Group。

上午模拟赛，下午改题。T4 卡不过去，交换 ST 表数组两维就过了。

晚上尝试改模拟费用流，没改出来。

Because of You - Kelly Clarkson

I will not make

The same mistakes that you did

I will not let myself

Cause my heart so much misery

I will not break

The way you did, you fell so hard

I've learned the hard way

To never let it get that far

Because of you

I never stray too far from the sidewalk

Because of you

I learned to play on the safe side so I don't get hurt

Because of you

I find it hard to trust not only me, but everyone around me

Because of you

I am afraid

I lose my way

And it's not too long before you point it out

I cannot cry

Because I know that's weakness in your eyes

I'm forced to fake

A smile, a laugh everyday of my life

My heart can't possibly break

When it wasn't even whole to start with

Because of you

I never stray too far from the sidewalk

Because of you

I learned to play on the safe side so I don't get hurt

Because of you

I find it hard to trust not only me

but everyone around me

Because of you

I am afraid

I watched you die

I heard you cry every night in your sleep

I was so young

You should have known

Better than to lean on me

You never thought of anyone else

You just saw your pain

And now I cry in the middle of the night

For the same damn thing

Because of you

I never stray too far from the sidewalk

Because of you

I learned to play on the safe side so I don't get hurt

Because of you

I try my hardest just to forget everything

Because of you

I don't know how to let anyone else in

Because of you

I'm ashamed of my life

Because it's empty

Because of you

I am afraid

Because of you

Because of you

早晨调模拟费用流，没调出来。

上午模拟赛开题顺序 T1 T3 T4 T2，T2 最后才做出来，比较惊险，但是先写完 T3 和 T4 暴力好像还不错。

然后 T2 就 \(O(3^n)\) 被卡常了，T3 树剖写挂，掉 \(20\) 警钟长鸣。

T4 不会改，把模拟费用流调出来了。

明天 11 月！
