题目描述
Bear Limak has $n$ colored balls, arranged in one long row. Balls are numbered $1$ through $n$ , from left to right. There are $n$ possible colors, also numbered $1$ through $n$ . The $i$ -th ball has color $t_{i}$ .
For a fixed interval (set of consecutive elements) of balls we can define a dominant color. It's a color occurring the biggest number of times in the interval. In case of a tie between some colors, the one with the smallest number (index) is chosen as dominant.
There are  non-empty intervals in total. For each color, your task is to count the number of intervals in which this color is dominant.

输入格式
The first line of the input contains a single integer $n$ ( $1<=n<=5000$ ) — the number of balls.
The second line contains $n$ integers $t_{1},t_{2},...,t_{n}$ ( $1<=t_{i}<=n$ ) where $t_{i}$ is the color of the $i$ -th ball.
The second line contains $n$ integers $t_{1},t_{2},...,t_{n}$ ( $1<=t_{i}<=n$ ) where $t_{i}$ is the color of the $i$ -th ball.
输出格式
Print $n$ integers. The $i$ -th of them should be equal to the number of intervals where $i$ is a dominant color.

说明/提示
In the first sample, color $2$ is dominant in three intervals:
- An interval $[2,2]$ contains one ball. This ball's color is $2$ so it's clearly a dominant color.
- An interval $[4,4]$ contains one ball, with color $2$ again.
- An interval $[2,4]$ contains two balls of color $2$ and one ball of color $1$ .
There are $7$ more intervals and color $1$ is dominant in all of them.
