阳光宅男 - 周杰伦
钥匙挂腰带 皮夹插后面口袋
黑框的眼镜有几千度来海边穿西装裤
他不在乎 我却想哭
有点无助 他的样子像刚出土的文物
他烤肉竟然会 自带水壶
写信时用浆糊 走起路一不注意就撞树
我不想输 就算辛苦
我也要等我也不能让你再走寻常路
我决定插手你的人生
当你的时尚顾问
别说你不能
让我们乘着阳光 海上冲浪
吸引她目光
不要怕露出胸膛 流一点汗
你成了型男
让我们乘着阳光 看着远方
别当路人甲
让美女缺氧 靠在你肩膀
我微笑在你旁边撑伞
喔对了对女生 用心疼 约会要等
讲笑话不能闷 别太冷 像我一样就刚好
对爱的人 接吻要深
拥抱要真 来电显示给个甜蜜的昵称
穿着要个性 这只是刚刚入门
接下来你还要 会弹琴会写歌 会双截棍
头脑清楚 不能迷糊
我要将你彻底改造 基因重组大变身
我决定插手你的人生
当你的时尚顾问
别说你不能
让我们乘着阳光 海上冲浪
吸引她目光
不要怕露出胸膛 流一点汗
你成了型男
让我们乘着阳光 看着远方
别当路人甲
让美女缺氧 靠在你肩膀
我微笑在你旁边撑伞
让我们乘着阳光 海上冲浪
吸引她目光
不要怕露出胸膛 流一点汗
你成了型男
让我们乘着阳光 看着远方
别当路人甲
让美女缺氧 靠在你肩膀
我微笑在你旁边撑伞
上午模拟赛，下午改题，T4 不会。
晚上吃饭回来发了信息学考资料，打算晚上看一下。

Treasure - Bruno Mars
Give me your, give me your, give me your attention, baby
I gotta tell you a little somethin’ about yourself
You're wonderful, flawless, ooh, you a sexy lady
But you walk around here like you wanna be someone else
Ooh, whoa
I know that you don’t know it, but you're fine, so fine
Ooh, whoa
Oh girl, I’m gonna show you when you're mine, oh mine
Treasure, that is what you are
Honey, you're my golden star
I know you could make my wish come true
If you let me treasure you
If you let me treasure oh-oh-you
Pretty girl, pretty girl, pretty girl, you should be smiling
A girl like you should never look so blue
You're everything I see in my dreams
I wouldn’t say that to you if it wasn’t true
Oh, whoa
I know that you don’t know it, but you're fine, so fine
Oh whoa
Oh, girl I’m gonna show you when you're mine, oh mine
Treasure, that is what you are
Honey, you're my golden star
You think you could make my wish come true
If you let me treasure you
If you let me treasure oh-oh-you
You are my treasure, you are my treasure
You are my treasure, yeah, you, you, you, you are
You are my treasure, you are my treasure
You are my treasure, yeah, you, you, you, you are
Treasure, that is what you are
Honey, you're my golden star
I know you could make my wish come true
If you let me treasure you
If you let me treasure oh-oh-you
早晨补了个 CF 题，没写完。
上午模拟赛比较简单，两个多小时就做完了，但是 T4 有点卡常没过，痛失 AK。
打完把 CF 题写完了，一次过了样例但是 WA 了。调了一下午一晚上，把所有可能状态都造出来搜一遍发现是值域 \([0,2^{30})\) 写的 for(int k=0;k<29;++k)，有点抽象。下一道随出来一个 ARC 的 F。
11.3
Sugar - Maroon 5
I'm hurting, baby, I'm broken down
I need your loving, loving, I need it now
When I'm without you
I'm something weak
You got me begging
Begging, I'm on my knees
I don't wanna be needing your love
I just wanna be deep in your love
And it's killing me when you're away
Ooh, baby,
'Cause I really don't care where you are
I just wanna be there where you are
And I gotta get one little taste
Your sugar
Yes, please
Won't you come and put it down on me
I'm right here, 'cause I need
Little love and little sympathy
Yeah you show me good loving
Make it alright
Need a little sweetness in my life
Your sugar
Yes, please
Won't you come and put it down on me
My broken pieces
You pick them up
Don't leave me hanging, hanging
Come give me some
When I'm without ya
I'm so insecure
You are the one thing
The one thing, I'm living for
I don't wanna be needing your love
I just wanna be deep in your love
And it's killing me when you're away
Ooh, baby,
'Cause I really don't care where you are
I just wanna be there where you are
And I gotta get one little taste
Your sugar
Yes, please
Won't you come and put it down on me
I'm right here, 'cause I need
Little love and little sympathy
Yeah you show me good loving
Make it alright
Need a little sweetness in my life
Your Sugar! (Your sugar!)
Yes, please (Yes, please)
Won't you come and put it down on me
Yeah
I want that red velvet
I want that sugar sweet
Don't let nobody touch it
Unless that somebody's me
I gotta be a man
There ain't no other way
'Cause girl you're hotter than southern California Bay
I don't wanna play no games
I don't gotta be afraid
Don't give all that shy shit
No make up on, that's my
Sugar
Yes, please
Won't you come and put it down on me (down on me!)
Oh, right here (right here),
'Cause I need (I need)
Little love and little sympathy
Yeah you show me good loving

Your sugar! (Sugar!)
Yes, please (Yes, please)
Won't you come and put it down on me
Your sugar
Yes, please
Won't you come and put it down on me
I'm right here, 'cause I need
Little love and little sympathy
Yeah you show me good loving
Make it alright
Need a little sweetness in my life
Your sugar
Yes, please
Won't you come and put it down on me
(Down on me, down on me)
早晨看了看这个 F，感觉找到点策略。
上午考了一场模拟赛。T1 博弈论结论题，T2 T3 T4 三个概率期望，【数据删除】，太难。题目诡异得我都想在博客里发抽象 emoji 了。
下午晚上改题。
又想了想 F 得到了一个类似求出链单调栈以及每个点不增加权值能到达的最小位置，之后贪心走，但是不会贪心走。看题解说是先二分，但转成判定性我也不会。

北京北京 - 汪峰
当我走在这里的每一条街道
我的心似乎从来都不能平静
除了发动机的轰鸣和电气之音
我似乎听到了它烛骨般的心跳
我在这里欢笑 我在这里哭泣
我在这里活着 也在这儿死去
我在这里祈祷 我在这里迷惘
我在这里寻找 在这里失去
北京 北京
咖啡馆与广场有三个街区
就像霓虹灯到月亮的距离
人们在挣扎中相互告慰和拥抱
寻找着追逐着奄奄一息的碎梦
我们在这儿欢笑 我们在这儿哭泣
我们在这儿活着 也在这儿死去
我们在这儿祈祷 我们在这儿迷惘
我们在这儿寻找 也在这儿失去
北京 北京
如果有一天我不得不离去
我希望人们把我埋在这里
在这儿我能感觉到我的存在
在这儿有太多让我眷恋的东西
我在这里欢笑 我在这里哭泣
我在这里活着 也在这儿死去
我在这里祈祷 我在这里迷惘
我在这里寻找 也在这儿失去

上午模拟赛，T3 挺厉害的构造，T4 写了个分块，不能在线，恼了。T3 题解写太抽象，看了半天才看懂。
明天早晨能晚起，好像还下雨。
T4 没改完。
11.5
存在 - 汪峰
多少人走着却困在原地
多少人活着却如同死去
多少人爱着却好似分离
多少人笑着却满含泪滴
谁知道我们该去向何处
谁明白生命已变为何物
是否找个借口继续苟活
或是展翅高飞保持愤怒
我该如何存在
多少次荣耀却感觉屈辱
多少次狂喜却倍受痛楚
多少次幸福却心如刀绞
多少次灿烂却失魂落魄
谁知道我们该梦归何处
谁明白尊严已沦为何物
是否找个理由随波逐流
或是勇敢前行挣脱牢笼
我该如何存在
谁知道我们该去向何处
谁明白生命已变为何物
是否找个借口继续苟活
或是展翅高飞保持愤怒
谁知道我们该梦归何处
谁明白尊严已沦为何物
是否找个理由随波逐流
或是勇敢前行挣脱牢笼
我该如何存在
下了一上午雨，有点冷。
上午把昨天 T4 改完了，下午看懂了 F 题解写了。晚上在做上一场 ARC 赛时没做出来的 C。
感觉好像会了，计数还得再想想。

怒放的生命 - 汪峰
曾经多少次跌倒在路上
曾经多少次折断过翅膀
如今我已不再感到彷徨
我想超越这平凡的奢望
我想要怒放的生命
就像飞翔在辽阔天空
就像穿行在无边的旷野
拥有挣脱一切的力量
曾经多少次失去了方向
曾经多少次破灭了梦想
如今我已不再感到迷茫
我要我的生命得到解放
我想要怒放的生命
就像飞翔在辽阔天空
就像穿行在无边的旷野
拥有挣脱一切的力量
我想要怒放的生命
就像矗立在彩虹之巅
就像穿行在璀璨的星河
拥有超越平凡的力量
曾经多少次失去了方向
曾经多少次破灭了梦想
如今我已不再感到迷茫
我要我的生命得到解放
我想要怒放的生命
就像飞翔在辽阔天空
就像穿行在无边的旷野
拥有挣脱一切的力量
我想要怒放的生命
就像矗立在彩虹之巅
就像穿行在璀璨的星河
拥有超越平凡的力量
我想要怒放的生命
就像飞翔在辽阔天空
就像穿行在无边的旷野
拥有挣脱一切的力量
我想要怒放的生命
就像矗立在彩虹之巅
就像穿行在璀璨的星河
拥有超越平凡的力量
早晨大概把计数部分想明白了。
上午模拟赛，前两题不会，但是 T3 状压然后减少状态过了，但是前两题不会。
改完题把计数题写完了，这题 ARC 赛时仔细想想可能也能想出来，但是一些细节能不能尽善尽美就不知道了。
晚上看了个 CF 数据结构，找到了个性质也没受到启发。
11.7
Counting Sheep - SAFIA
I never make a sound
Fingers crossed I shut my mouth
Thoughts they're creeping through my teeth
Drip, drop, the night is loud
Silence seems to drown me out
Box my thoughts and give me some relief
I wanna let you down
Make you toss and turn around
Won't you give me what I need
I wanna let you down
And I'm always lost and never found
Won't you give me what I need
Tick, tock, make me creep
Never ending
Counting sheep oh
Never get no sleep
Tick, tock, make me creep
Never ending
Counting sheep oh
Never get no sleep
Do you know what the most frightening thing in the world is it's fear
Did you plan on going to bed in the near future no
There's nothing to worry about you're going to be just fine
But whatever you do
Don't fall asleep
Don't drop the curtains down
Darkness is the whole surround
My mind is lurking at my feet (At my feet)
Criss, Cross, the night is sour
Pupils fixed on every hour
Sunrise is the only thing that's sweet
I wanna let you down
Make you toss and turn around
Won't you give me what I need (What I need)
I wanna let you down
And I'm always lost and never found
Won't you give me what I need
Tick, tock, make me creep
Never ending
Counting sheep oh
Never get no sleep
Tick, tock, make me creep
Never ending
Counting sheep oh
Never get no sleep
Tick, tock, make me creep
Never ending
Counting sheep oh
Never get no sleep
Tick, tock, make me creep
Never ending
Counting sheep oh
Never get no sleep
上午模拟赛，T1 写了发 FWT，非常舒适，感谢出题人值域和数组大小同阶，结果除以二没乘逆元挂分了。T2 凭借优异的取模优化把 \(100\) 优化到了 \(60\) 分。T3 连边然后主席树树上差分和题库里的一道题很像啊，但是没想到。
晚上把 T4 改了，第一步单调就没想到。

春风十里 - 鹿先森乐队
我在二环路的里边 想着你
你在远方的山上 春风十里
今天的风吹向你 下了雨
我说所有的酒 都不如你
我在鼓楼的夜色中 为你唱花香自来
在别处 沉默相遇和期待
飞机飞过 车水马龙的城市
千里之外 不离开
把所有的春天 都揉进了一个清晨
把所有停不下的言语变成秘密 关上了门
莫名的情愫啊 请问 谁来将它带走呢
只好把岁月化成歌 留在山河
我在鼓楼的夜色中 为你唱花香自来
在别处 沉默相遇和期待
飞机飞过 车水马龙的城市
千里之外 不离开
把所有的春天 都揉进了一个清晨
把所有停不下的言语变成秘密 关上了门
莫名的情愫啊 请问 谁来将它带走呢
只好把岁月化成歌 留在山河

今天的风吹向你 下了雨
我说所有的酒 都不如你
上午模拟赛，T3 成功做到了删去原题中 corner cases 样例并把每个捆绑都加入了 corner cases，还有子任务依赖。下午把题改了。
发通知说 11 号放假。
晚上把 Easy Version 过了，考虑根号分治，又想出来一些性质，但是不会。
11.9
Rolling in the Deep - Adele Adkins
There's a fire starting in my heart
Reaching a fever pitch and it's bringing me out the dark
Finally I can see you crystal clear
Go ahead and sell me out and I'll lay your ship bare
See how I leave with every piece of you
Don't underestimate the things that I will do
There's a fire starting in my heart
Reaching a fever pitch
And it's bringing me out the dark
The scars of your love remind me of us
They keep me thinking that we almost had it all
The scars of your love, they leave me breathless
I can't help feeling
We could have had it all
(You're gonna wish you never had met me)
Rolling in the deep
(Tears are gonna fall, rolling in the deep)
You had my heart inside of your hand
(You're gonna wish you never had met me)
And you played it, to the beat
(Tears are gonna fall, rolling in the deep)
Baby, I have no story to be told
But I've heard one on you
And I'm gonna make your head burn
Think of me in the depths of your despair
Make a home down there
As mine sure won't be shared
(You're gonna wish you never had met me)
The scars of your love remind me of us
(Tears are gonna fall, rolling in the deep)
They keep me thinking that we almost had it all
(You're gonna wish you never had met me)
The scars of your love, they leave me breathless
(Tears are gonna fall, rolling in the deep)
I can't help feeling
We could have had it all
(You're gonna wish you never had met me)
Rolling in the deep
(Tears are gonna fall, rolling in the deep)
You had my heart inside of your hand
(You're gonna wish you never had met me)
And you played it, to the beat
(Tears are gonna fall, rolling in the deep)
We could have had it all
Rolling in the deep
You had my heart inside of your hand
But you played it, with a beating
Throw your soul through every open door (woah)
Count your blessings to find what you look for (woah)
Turn my sorrow into treasured gold (woah)
You'll pay me back in kind and reap just what you sow(woah)
(You're gonna wish you never had met me)
We could have had it all
(Tears are gonna fall, rolling in the deep)
We could have had it all
(You're gonna wish you never had met me)
It all, it all, it all
(Tears are gonna fall, rolling in the deep)
We could have had it all
(You're gonna wish you never had met me)
Rolling in the deep
(Tears are gonna fall, rolling in the deep)
You had my heart inside of your hand
(You're gonna wish you never had met me)
And you played it to the beat
(Tears are gonna fall, rolling in the deep)
We could have had it all
(You're gonna wish you never had met me)
Rolling in the deep
(Tears are gonna fall, rolling in the deep)
You had my heart inside of your hand
(You're gonna wish you never had met me)
But you played it
You played it
You played it
You played it to the beat
早晨起来好像会 Hard Version 了。
上午模拟赛写完把 Hard Version 过了，看了眼 lxl 课件发现给加强到 \(5\times 10^7\) 了。
下午被拉去体测了，测了个跳远，然后信息学考课。
感觉这几天模拟赛考得一半，确实两小时可以“会做”两道，但是其他两道题没什么亮点，还会挂分。
看了下 lxl 课件做法，感觉不是很好实现。线性，太难，建议取消线性。

I'm not the Only One - Sam Smith
I'm Not The Only One - Sam Smith
You and me we made a vow
For better or for worse
I can't believe you let me down
But the proof is in the way it hurts
For months on end I've had my doubts
Denying every tear
I wish this would be over now
But I know that I still need you here
You say I'm crazy
Cause you don't think I know what you've done
But when you call me baby
I know I'm not the only one
You've been so unavailable
Now sadly I know why
Your heart is unobtainable
Even though lord knows you kept mine
You say I'm crazy
Cause you don't think I know what you've done
But when you call me baby
I know I'm not the only one
I have loved you for many years
Maybe I am just not enough
You've made me realise my deepest fear
By lying and tearing us up
You say I'm crazy
Cause you don't think I know what you've done
But when you call me baby
I know I'm not the only one
You say I'm crazy
Cause you don't think I know what you've done
But when you call me baby
I know I'm not the only one
I'm always not the only one
I'm always not the only one
And I know And I know And I know And I know
And I know And I know
I know I'm not the only one
昨天晚上看了个树上交互，晚上躺床上想想好像会了，又想想好像假了。
上午模拟赛，最后俩小时一直做不出 T3。T2 挂分了。
T4 非常抽象的部分分分布，赛后得知好像是 lxl 弄的，但这数据结构也太水了。
中午起床把秋裤穿了，感觉非常爽，秋裤成 DPOY 了。
下午改完题也不是很想做这个交互，于是写了个区间 sin 和水一水，看了个我是仙人掌也不很会。
明天下午放假，晚上水哥告知明天还有模拟赛，上午随机打摆的愿望破灭了，只能晚上阅读一些 yspm 文字。从日记跳转到了杂题乱写，然后回忆了一下 NOI2016 优秀的拆分这题，只记得是枚举长度设关键点调和级数了。

修炼爱情 - 林俊杰
凭什么要失望
藏眼泪到心脏
往事不会说谎 别跟它为难
我们两人之间不需要这样
我想
修炼爱情的心酸
学会放好以前的渴望
我们那些信仰 要忘记多难
远距离的欣赏 近距离的迷惘
谁说太阳会找到月亮
别人有的爱 我们不可能模仿
修炼爱情的悲欢
我们这些努力不简单
快乐炼成泪水 是一种勇敢
几年前的幻想 几年后的原谅
为一张脸去养一身伤
别讲想念我 我会受不了这样
记忆它真嚣张
路灯把痛点亮
情人一起看过多少次月亮
它在天空看过多少次遗忘
多少心慌
修炼爱情的心酸
学会放好以前的渴望
我们那些信仰 要忘记多难
远距离的欣赏 近距离的迷惘
谁说太阳会找到月亮
别人有的爱 我们不可能模仿
修炼爱情的悲欢
我们这些努力不简单
快乐炼成泪水 是一种勇敢
几年前的幻想 几年后的原谅
为一张脸去养一身伤
别讲想念我 我会受不了这样
笑着说爱让人疯狂
哭着说爱让人紧张
忘不了那个人就投降
修炼爱情的悲欢
我们这些努力不简单
快乐炼成泪水 是一种勇敢
几年前的幻想 几年后的原谅
为一张脸去养一身伤
别讲想念我 我会受不了这样
几年前的幻想 几年后的原谅
为一张脸去养一身伤
别讲想念我 我会受不了这样
早晨摆了。
上午模拟赛，是下午洛谷 NOIP 模拟赛的线下版本，类似全真模拟。T1 挺水的。
T2 致敬喵了个喵，发现偶数可以变成奇数问题，发现每次增加 \(2\) 好像能做，然后会了 \(t=1\)，感觉不是很好写就先看 T3。T3 有点诈骗啊，最小值方案数是阶乘级别的，\(n\) 很大就直接算了，有 \(52\) 就写了。
回来把 T2 写了，模了模感觉最后的部分换个顺序就能 \(t=2\)，不是很清楚应该按照什么形式化顺序。
T4 只会暴力和两个特殊性质。最后试了试 T2 的抽象做法，写了个 \(O(n^3)\) 试了几个都构造成功了，然后就结束了。
下午放假，摆了。
晚上出分了，\(100+70+52+24=246\)，T4 挂了一个特殊性质。

Shape of You - Ed Sheeran
The club isn't the best place to find a lover
So the bar is where I go
Me and my friends at the table doing shots
Drinking faster and then we talk slow
You come over and start up a conversation with just me
And trust me I'll give it a chance now
Take my hand, stop, Put Van The Man on the jukebox
And then we start to dance, and now I'm singing like
Girl, you know I want your love
Your love was handmade for somebody like me
Come on now, follow my lead
I may be crazy, don't mind me, say
Boy, let's not talk too much
Grab on my waist and put that body on me
Come on now, follow my lead
Come—come on now, follow my lead
I'm in love with the shape of you
We push and pull like a magnet do
Although my heart is falling too
I'm in love with your body
And last night you were in my room
And now my bedsheets smell like you
Every day discovering something brand new
I'm in love with your body
Oh—i—oh—i—oh—i—oh—i
Oh—i—oh—i—oh—i—oh—i
I'm in love with your body
Oh—i—oh—i—oh—i—oh—i
Oh—i—oh—i—oh—i—oh—i
I'm in love with your body
Oh—i—oh—i—oh—i—oh—i
Oh—i—oh—i—oh—i—oh—i
I'm in love with your body
Every day discovering something brand new
I'm in love with the shape of you
One week in we let the story begin
We're going out on our first date
But you and me are thrifty so go all you can eat
Fill up your bag and I fill up a plate
We talk for hours and hours about the sweet and the sour
And how your family is doin' okay
And leave and get in a taxi, we kiss in the backseat
Tell the driver make the radio play, and I'm singing like
Girl, you know I want your love
Your love was handmade for somebody like me
Come on now, follow my lead
I may be crazy, don't mind me, say
Boy, let's not talk too much
Grab on my waist and put that body on me
Come on now, follow my lead
Come—come on now, follow my lead
I'm in love with the shape of you
We push and pull like a magnet do
Although my heart is falling too
I'm in love with your body
And last night you were in my room
And now my bedsheets smell like you
Every day discovering something brand new
I'm in love with your body
Oh—i—oh—i—oh—i—oh—i
Oh—i—oh—i—oh—i—oh—i
I'm in love with your body
Oh—i—oh—i—oh—i—oh—i
Oh—i—oh—i—oh—i—oh—i
I'm in love with your body
Oh—i—oh—i—oh—i—oh—i
Oh—i—oh—i—oh—i—oh—i
Every day discovering something brand new
I'm in love with the shape of you
Come on, be my baby, come on
Come on, be my baby, come on
Come on, be my baby, come on
Come on, be my baby, come on
Come on, be my baby, come on
Come on, be my baby, come on
Come on, be my baby, come on
Come on, be my baby, come on
I'm in love with the shape of you
We push and pull like a magnet too
Although my heart is falling too
I'm in love with your body
And last night you were in my room
And now my bedsheets smell like you
Every day discovering something brand new
I'm in love with your body
Come on, be my baby, come on
Come on, be my baby, come on
I'm in love with your body
Come on, be my baby, come on
Come on, be my baby, come on
I'm in love with your body
Come on, be my baby, come on
Come on, be my baby, come on
I'm in love with your body
Every day discovering something brand new
I'm in love with the shape of you
上午摆了。
下午开学了，把 T2 改了，挺怪的构造，“和出题人脑电波对上了就能做出来”，也不知道当时赛时想得莫名其妙填法为啥是对的。
晚上把 T3 改了，比较小的时候应该先考虑设计状态 DP 啊。
晚上走之前好像看懂 T4 了。
11.13
Something Just Like This - The Chainsmokers/Coldplay
I've been reading books of old
The legends and the myths
Achilles and his gold
Hercules and his gifts
Spiderman's control
And Batman with his fists
And clearly I don't see myself upon that list
But she said where'd you wanna go
How much you wanna risk
I'm not looking for somebody
With some Superhuman gifts
Some Superhero
Some fairytale bliss
Just something I can turn to
Somebody I can kiss
I want something just like this
Oh I want something just like this
Oh I want something just like this
I want something just like this
I've been reading books of old
The legends and the myths
The testaments they told
The moon and its eclipse
And Superman unrolls
A suit before he lifts
But I'm not the kind of person that it fits
She said where'd you wanna go
How much you wanna risk
I'm not looking for somebody
With some Superhuman gifts
Some Superhero
Some fairytale bliss
Just something I can turn to
Somebody I can miss
I want something just like this
I want something just like this
Oh I want something just like this
Oh I want something just like this
Where'd you wanna go
How much you wanna risk
I'm not looking for somebody
With some Superhuman gifts
Some Superhero
Some fairytale bliss
Just something I can turn to
Somebody I can kiss
I want something just like this
Oh I want something just like this
上午打了模拟赛，题有点别扭，做起来很难受。
下午改了前三题，T4 要 wqs 二分优化，但是我不会。
晚上把洛谷模拟赛 T4 改了，走之前看了看 wqs 二分。

I Need A Doctor - Eminem/Dr. Dre/Skylar Grey
I’m about to lose my mind
You’ve been gone for so long
I’m running out of time
I need a doctor
Call me a doctor
I need a doctor, doctor
To bring me back to life
I told the world one day I would pay it back
Say it on tape, and lay it, record it
So that one day I could play it back
But I don’t even know if I believe it when i'm saying that
ya'll startin' to creep in, everyday it’s just so grey and black
Hope，I just need a ray of that
’Cause no one see's my vision when I play it for ‘em
They just say it’s wack
But they don’t know what dope is
And I don’t know if I was awake or asleep，When I wrote this
All I know is you came to me when I was at my lowest
You picked me up, breathed new life in me
I owe my life to you
Before the life of me, I don't see why you don't see like I do
But it just dawned on me you lost a son
Demon's fightin' you. it’s dark. Let me turn on the lights and brighten me and enlighten you
I dont think you realise what you mean to me
Not the slightest clue
‘Cause me and you were like a crew
I was like your sidekick
You’ll either wanna fight when I get off this f-cking mic
Or you're gonna hug me
But I’m out of option, there‘s nothing else I can do ‘cause…
I’m about to lose my mind
You’ve been gone for so long
I’m running out of time
I need a doctor
Call me a doctor
I need a doctor, doctor
To bring me back to life
It hurts when I see you struggle
You come to me with ideas
You say there just pieces so I’m puzzled
’Cause the shit I hear is crazy
But your either getting lazy or you don’t believe in you no more
Seems like your own opinions, no one you can form
Can't make a decision you keep questioning yourself
Second guessing and it‘s almost like your begging for my help
Like I’m your leader
You’re supposed to f-cking be my mentor
I can endure no more,
I demand you remember who you are
It was YOU, who believed in me
When everyone was telling you don‘t sign me
Everyone at the f-cking label
Let's tell the truth，You risked your career for me
I know it as well as you
Nobody wanted to f-ck with the white boy
Dre I’m crying in this booth
You saved my life, now maybe it’s my turn to save yours
But I can never repay you what you did for me is way more
But I ain‘t giving up faith and you ain’t giving up on me
Get up Dre, I’m dying I need you, come back for f-cks sake
I’m about to lose my mind
You’ve been gone for so long
I’m running out of time
I need a doctor
Call me a doctor
I need a doctor, doctor
To bring me back to life
It literally feels like a lifetime ago
But I still remember the shit like it was just yesterday though
You walked in, yellow jump suit
Whole room, cracked jokes
Once you got inside the booth, told you, like smoke
Went through friends, some of them I put on
But they just left, they said they was riding to a death
But where the f-ck are they now
Now that I need them I dont see none of them
All I see is Slim
F-ck all you fair-weather friends
All I need is him
F-cking backstabbers
When the chips were down you just laughed at us
Now you about to feel the f-cking wrath of aftermath, faggots
You gon see us in our lab jackets and ask us where the f-ck we been?
You can kiss my indecisive ass crack maggots and the crackers ass
Little cracker jack beat making wack math,
Backwards producers, Im back bastards
One more CD and then I’m packing up my bags and as I’m leaving
And I guarantee they'll scream Dre don’t leave us like that man ‘cause…
I’m about to lose my mind
You’ve been gone for so long
I’m running out of time
I need a doctor
Call me a doctor
I need a doctor, doctor
To bring me back to life
To bring me back to life
昨天晚上看了 Meteor 一道树上游走，他说做过差不多的，然后我不会，于是早晨观摩了一下他写的博客。
上午模拟赛，T1 和 T2 都做出来了，但是 T1 被 UU hack 了，T2 开了 long long 没用。T3 和 T4 看榜大家都有很多部分分，但是我不咋会。
明天下午信息学考，晚上加训。
最后看了看四边形不等式。

Mockingbird - Eminem
Yeah I know sometimes
Things may not always make sense to you right now
But hey what'd Daddy always tell you
Straighten up little soldier
Stiffen up that upper lip
What you cryin' about you got me
Hailie I know you miss your mom
And I know you miss your dad when I'm gone
But I'm tryin' to give you the life that I never had
I can see you're sad even when you smile even when you laugh
I can see it in your eyes deep inside you wanna cry
Cause you're scared I ain't there
Daddy's with you in your prayers
No more crying wipe them tears
Daddy's here no more nightmares
We gon' pull together through it we gon' do it
Lainie Uncle's crazy ain't he
Yeah but he loves you girl and you better know it
We're all we got in this world
When it spins when it swirls when it whirls when it twirls
Two little beautiful girls
Looking puzzled in a daze I know it's confusing you
Daddy's always on the move
Momma's always on the news
I try to keep you sheltered from it but somehow it seems
The harder that I try to do that the more it backfires on me
All the things growing up as Daddy that he had to see
Daddy don't want you to see
But you see just as much as he did
We did not plan it to be this way your mother and me
But things have got so bad between us
I don't see us ever being together ever again
Like we used to be when we was teenagers
But then of course everything always happens for a reason
I guess it was never meant to be
But it's just something we have no control over
And that's what destiny is
But no more worries rest your head and go to sleep
Maybe one day we'll wake up and this'll all just be a dream
Hook
Now hush little baby don't you cry
Everything's gonna be alright
Stiffen that upper lip up little lady I told ya
Daddy's here to hold ya through the night
I know Mommy's not here right now
And we don't know why
We fear how we feel inside
It may seem a little crazy pretty baby
But I promise Momma's gon' be alright
Heh it's funny
I remember back one year when Daddy had no money
Mommy wrapped the Christmas presents up
And stuck 'em under the tree
And said some of 'em were from me
Cause daddy couldn't buy 'em
I'll never forget that Christmas I sat up the whole night cryin'
Cause Daddy felt like a bum see Daddy had a job
But his job was to keep the food on the table for you and Mom
And at the time every house that we lived in
Either kept getting broken into and robbed or shot up on the block
And your mom was saving money for you in a jar
Tryin' to start a piggy bank for you so you could go to college
Almost had a thousand dollars
'Til someone broke in and stole it
And I know it hurt so bad it broke your momma's heart
And it seemed like everything was just starting to fall apart
Mom and Dad was arguing a lot
So Momma moved back on to Chalmers
In the flat one bedroom apartment
And Dad moved back to the other side of 8 Mile on Novara
And that's when Daddy went to California with his CD
And met Dr. Dre and flew you and Momma out to see me
But Daddy had to work you and momma had to leave me
Then you started seeing Daddy on the TV
And Momma didn't like it
And you and Lainie were too young to understand it
Papa was a rolling stone Momma developed a habit
And it all happened too fast for either one of us to grab it
I'm just sorry you were there and had to witness it first hand
Cause all I ever wanted to do was just make you proud
Now I'm sittin' in this empty house
Just reminiscing looking at your baby pictures it just trips me out
To see how much you both have grown
It's almost like you're sisters now
Wow guess you pretty much are and daddy's still here
Lainie I'm talking to you too daddy's still here
I like the sound of that yeah it's got a ring to it don't it
Sssshhh Momma's only gone for the moment
Now hush little baby don't you cry
Everything's gonna be alright
Stiffen that upper lip up little lady I told ya
Daddy's here to hold ya through the night
I know Mommy's not here right now
And we don't know why
We fear how we feel inside
It may seem a little crazy pretty baby
But I promise Momma's gon' be alright
And if you ask me to Daddy's gonna buy you a mockingbird
I'ma give you the world
I'ma buy a diamond ring for you I'ma sing for you
I'll do anything for you to see you smile
And if that mockingbird don't sing and that ring don't shine
I'ma break that birdie's neck
I'll go back to the jeweler who sold it to ya
And make him eat every carat don't fuck with Dad ha ha
上午模拟赛，题都很水，纯纯卡常 round。
下午信息学考。
晚上学了下二分队列。
NOIP 部分见游记，剩下时间自己补补 whk，所以日记断更！
最后一首歌。
Sofía - Álvaro Soler
Sueño cuando era pequeño
Sin preocupación, en el corazón
Sigo viendo aquel momento
Se desvaneció, desapareció
Ya no te creo, ya no te deseo (eh-oh)
Solo te dejo, solo te deseo (eh-oh)
Mira, Sofía
Sin tu mirada sigo
Sin tu mirada sigo
Dime, Sofía-ah-ah
Cómo te mira, dime
Cómo te mira, dime
Sé que no, sé que no
Sé que sólo
Sé que ya no soy-oy-oy-oy
Mira, Sofía
Sin tu mirada sigo
Sin tu mirada, Sofía
Dices que éramos felices
Todo ya pasó, todo ya pasó
Sé que te corté las alas
El te hizo volar, el te hizo soñar
Ya no te creo, ya no te deseo (eh-oh)
Sólo te dejo, sólo te deseo (eh-oh)
Mira, Sofía
Sin tu mirada sigo
Sin tu mirada sigo
Dime, Sofía-ah-ah
Cómo te mira, dime
Cómo te mira, dime
Sé que no, sé que no
Sé que sólo
Sé que ya no soy-oy-oy-oy
Mira, Sofía
Sin tu mirada sigo
Sin tu mirada, Sofía
Y ¿por qué no me dices la verdad?
Sigo sin tu mirada, Sofía
Y ¿por qué no me dices la verdad?
Mira, Sofía
Sin tu mirada sigo
Sin tu mirada
Dime, Sofía-ah-ah
Cómo te mira, dime
Cómo te mira, dime
Mira, Sofía
Sin tu mirada sigo
Sin tu mirada sigo
Dime, Sofía-ah-ah
Cómo te mira, dime
Cómo te mira, dime
Sé que no, sé que no
Sé que sólo
Sé que ya no soy-oy-oy-oy
Mira, Sofía
Sin tu mirada sigo
Sin tu mirada, Sofía
