所以斯特林多项式的一项怎么求？

SoyTony 语云：近端求值 .

其实也挺神奇的，核心问题是求 \([z^n]\left(\dfrac z{\mathrm e^z-1}\right)^k\) .

ln exp 之后就变成求 \(\left(\ln\dfrac z{\mathrm e^z-1}\right)^k\) 对于每个 \(k\) 求一个固定的位置 .

拉反就完了，这样就是对于一个固定的式子求每个位置了，需要牛顿迭代求复合逆所以是 \(\Theta(n\log n)\) .

就是 NaCly_Fish 的 Farewell 教导我们的 .

最后发现问题的根本不在于网络的限制，而在于网络的开放 .

Why Do I - Set It Off, 初音ミク

Sometimes I write you letters that you'll never read
When I get to drinkin', I get to thinkin'
I wish you were thinkin' about me (why do I?)
Sometimes I look for girls that look the way you do
So fucking stupid, started to do it
When I saw you with someone new (why do I?)
It's been ten months and 20 days
I'm the last thing that's on your brain
So why do I still wake up, two in the morning
Cold sweat, screamin' your name?
Why do I get drunk and look at your pictures?
Why do I feel this way?
Why do I do this to myself?
And why do I even try?
You don't, you don't
So baby, why do I? (Why do I? Why do I? Oh, oh)

Some nights, I think about the last time that we talked
Back in November, maybe December
All I remember is that you called me a piece of shit
Said you never wanna see my face again
You regret everything we ever did
You're obviously over it, so over it

So why do I still wake up, two in the morning
Cold sweat, screamin' your name?
Why do I get drunk and look at your pictures?
Why do I feel this way?
Why do I do this to myself?
And why do I even try?
You don't, you don't
So baby, why do I? (Why do I? Why do I?)

It's been ten months and 20 days
I've been wonderin' the same damn things

So why do I still wake up, two in the morning
Cold sweat, screamin' your name?
Why do I get drunk and look at your pictures?
Why do I feel this way?
Why do I do this to myself?
And why do I even try?
You don't, you don't
So baby, why do I?

why do I? Why do I?
(You don't, you don't) so baby, why do I?
(You don't, you don't) why do I? Why do I?
(You don't, you don't) so baby, why do I?
