解题思路：

暴力绝对TLE

一个队伍穿主场球衣的次数 = 这个队伍的客场球衣颜色与其他队主场球衣颜色起冲突的次数 + (n - 1)

#include <stdio.h>

#include <string.h>

#include <iostream>

using namespace std;

const int MAXSIZE = 100;

const int INF = 0x3f3f3f3f;



int a[100001], b[100001], c[100001], cnt[100001];

int main(){

    int t, i, j, m, n;

    memset(c, 0, sizeof(c));

    memset(cnt, 0, sizeof(cnt));

    scanf("%d",&n);

    for(i = 1; i <= n; ++i){

        scanf("%d%d",&a[i],&b[i]);

        ++cnt[a[i]];

    }

    for(i = 1; i <= n; ++i){

        c[i] += n - 1;

        c[i] += cnt[b[i]];

    }

    int temp = (n - 1) * 2;

    for(i = 1; i <= n; ++i){

        printf("%d %d\n",c[i],temp - c[i]);

    }

    return 0;

}
