题目描述

You are given a rooted tree with root in vertex $1$. Each vertex is coloured in some colour.

Let's call colour $c$ dominating in the subtree of vertex $v$ if there are no other colours that appear in the subtree of vertex $v$ more times than colour $c$. So it's possible that two or more colours will be dominating in the subtree of some vertex.

The subtree of vertex $v$ is the vertex $v$ and all other vertices that contains vertex $v$ in each path to the root.

For each vertex $v$ find the sum of all dominating colours in the subtree of vertex $v$.

输入格式

The first line contains integer $n (1 \leq n \leq 10^5)$ — the number of vertices in the tree.

The second line contains $n$ integers $c_i (1 \leq c_i \leq n)$, $c_i$ — the colour of the $i$-th vertex.

Each of the next $n - 1$ lines contains two integers $x_j, y_j (1 \leq x_j, y_j \leq n)$ — the edge of the tree. The first vertex is the root of the tree.

输出格式

Print $n$ integers — the sums of dominating colours for each vertex.
