28055번 - Monochrome Tree 서브태스크다국어

문제

A monochrome tree is a tree in which each vertex is colored either white or black. The score of a monochrome tree is equal to the number of unordered vertex pairs $(u, v)$ such that:

• Both vertices $u$ and $v$ are colored black.
• $u$ is an ancestor of $v,ドル or $v$ is an ancestor of $u$.

You are given a rooted tree of $n$ vertices whose root vertex is 1ドル$.

For each $k$ from 0ドル$ to $n$ (inclusive), you may color the given tree in such a way that there are exactly $k$ black vertices and $n - k$ white vertices. Among all the possible colorings, we denote the lowest score of a coloring as $c_k$.

Find $c_k$ for all 0ドル \leq k \leq n$.

입력

The first line contains a single integer $n,ドル the number of vertices in the given tree. (1ドル \leq n \leq 2 \times 10^5$).

The $i$-th line of the following $n-1$ lines contain a single integer $p_{i+1}$ (1ドル \leq p_{i+1} \leq n,ドル $p_{i+1} \neq i+1$), meaning that the parent of vertex $i+1$ is $p_{i+1}$.

출력

On the first and only line, print $n+1$ integers, the $i$-th of which denotes $c_{i-1}$. (1ドル \leq i \leq n+1$)

노트

Vertex $x$ is an ancestor of vertex $y$ $(x \neq y)$ if there is a sequence of vertices $\{x=a_1, a_2, \ldots a_k=y\}$ where $a_i$ is a parent of $a_{i+1}$ (1ドル \leq i \leq k-1$).
