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 ti.

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.

Input

The first line of the input contains a single integer n (1 ≤ n ≤ 5000) — the number of balls.

The second line contains n integers t1, t2, ..., tn (1 ≤ ti ≤ n) where ti is the color of the i-th ball.

Output

Print n integers. The i-th of them should be equal to the number of intervals where i is a dominant color.

output
6 0 0 
Note

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.

 题意: 给你n个数 共n*(n+1)/2个区间   求各个区间的众数作为标记数   若有多个众数 记录最小的数作为标记数  输出每个数 作为多少个区间的标记数

 题解: 暴力处理  记录各个区间的标记数。

 吃了 STL 的亏 用map 超时了 xjb用  用数组存就是 !!!!!
