THUPC 二缺一有人吗 . upd. 组到了 .

歌：DBD - 沉年旧诗 feat. 洛天依 .

这歌有点 ilem 的感觉 .

roki 都出本家翻唱了，阿良良木健老师也唱了无理无智 .

做了半天的小 Y 的背包计数问题也没有找到什么有意义的方向，但是发现一个比较趣味的问题：

X 计数

计算满足 \(\operatorname{mex}(\lambda)=\max(\lambda)+1\) 的整数拆分 \(\lambda\vdash n\) 的数量 .

算了有点太水了 . 也不知道做法对不对 .

你闲话就写这个？

当然不是啦，还有一些别的：

Euphoria - GameboyJones, CG5

Ahh, okay
One, two, three

I just jumped in the deep end, stress got me sinking
Looking for the light, but I can′t find the beacon
I been in a panic, dang, I've barely even eaten
Suppose to be the strongest, so I have to hide my weakness
Reckless abandon, running the streets
Thought I was doing this all right, but they keep running from me
So I′m just left feeling stranded, world's looking bleak
And now I gotta be the best 'cause everything is on me, yeah

Said they want me back, but don′t want to be a burdеn
Multitude of doubts, have me feeling rеal uncertain, I′m learning

People want to write your script, but I won't close the curtain
You gon′ know I earned it!

'Cause I ain′t 'bout to break down
No wasting time, I gotta gain ground
Made it through pain and all the rain clouds
Through troubled waters I have faced doubts, won′t break now
Euphoria
Life ain't always gonna be luxurious
I had guilt inside that almost tore me up
But I won't stop until I reach Euphoria, Euphoria

Well, I don′t know if I got any power left in me
With the overwhelming goals I know I got to reach
But they say experience will come and set you free
How do I know that if I can′t even get up on my feet, yeah?
I'm running out of time, so bring me back to life
And fake it ′til I make it to the other side
And breathe in, breathe out
I know I can do it

They call me a hero
Lifts me up when I feel low
They all count on me now
So by the sweat of my brow
I'll stand up and live up
To what they need me to be
Euphoria runs through me
Euphoria

′Cause I ain't ′bout to break down
No wasting time, I gotta gain ground
Made it through pain and all the rain clouds
Through troubled waters I have faced doubts
Won't break now
Euphoria
Life ain't always gonna be luxurious
I had guilt inside that almost tore me up
But I won′t stop until I reach Euphoria, Euphoria

Euphoria
Euphoria
Euphoria
Euphoria
Euphoria
Euphoria
Euphoria
Euphoria
Ooh, ye- yeah
Euphoria-a

对着 (*) 和 Jacobi 三重积看了半天……

结果直接暴力卷好像就 \(O(n\sqrt n)\) 了 .
