分析
设要求的东西是 $f_i$,考虑怎么求这个东西。
可以想到计算每个点在多少种方案中,进而想到计算每个点不在多少种方案中。于是容易得到包含 $u$ 的方案数为
$$
{n\choose i}-\sum_{v\in son_u}{sz_v\choose i}
$$
于是
$$
\begin{aligned}f_i&=\sum_{u=1}^n\left({n\choose i}-\sum_{v\in son_u}{sz_v\choose i}\right)\\&=n{n\choose i}-\sum_{u=1}^n\sum_{v\in son_u}{sz_v\choose i}\end{aligned}
$$
后面的部分可以考虑一个转化。设 $cnt_i$ 表示大小为 $i$ 的子树数量,于是
$$
\begin{aligned}f_i&=n{n\choose i}-\sum_{j=i}^ncnt_j{j\choose i}\\&=n{n\choose i}-\sum_{j=i}^ncnt_j\frac{j!}{i!(j-i)!}\\&=n{n\choose i}-\frac{1}{i!}\sum_{j=i}^n\frac{cnt_j\times j!}{(j-i)!}\end{aligned}
$$
令 $F_i=cnt_i\times i!$,$G_i=\frac{1}{i!}$,于是
$$
\begin{aligned}f_i&=n{n\choose i}-\frac{1}{i!}\sum_{j=i}^nF_j\times G_{j-i}\\&=n{n\choose i}-\frac{1}{i!}\sum_{j=0}^{n-i}F_{i+j}\times G_j\end{aligned}
$$
令 $FR\!_i=F_{n-i}$,于是
$$
\begin{aligned}f_i&=n{n\choose i}-\frac{1}{i!}\sum_{j=0}^{n-i}FR_{n-i-j}\times G_j\end{aligned}
$$
可以发现后面已经是卷积的形式了,于是直接 NTT 即可。虽然这个模数很奇怪,但是它确实是 NTT 模数。
