C. Bear and Colors

Description

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.

Sample Input

4
1 2 1 2

Sample Output

7 3 0 0

题意

有n个数,然后对于每个区间,这个区间的特征等于这个区间出现次数最多的数,如果有两个数出现的次数一样的话,那么就取较小的那个数

现在问你每个数当了多少次特征

题解:

n才5000,直接n^2枚举就好了,不要犹豫……

代码

#include<bits/stdc++.h>
using namespace std;
const int maxn = 5005;
int n,a[maxn],ans[maxn];
int H[maxn];
int main()
{
    scanf("%d",&n);
    for(int i=1;i<=n;i++)scanf("%d",&a[i]);
    for(int i=1;i<=n;i++)
    {
        memset(H,0,sizeof(H));
        int ans1=0,ans2=0;
        for(int j=i;j<=n;j++)
        {
            H[a[j]]++;
            if(ans1<H[a[j]]||(ans1==H[a[j]]&&a[j]<ans2))
            {
                ans1=H[a[j]];
                ans2=a[j];

            }
            ans[ans2]++;
        }
    }
    for(int i=1;i<=n;i++)
        printf("%d ",ans[i]);
    printf("\n");
}
