Sicily 4700 小明与奶牛 (难得水题)

别怪我，继续水

代码如下：

#include <stdio.h>int main(){int te;int a[3];int n;int i;int x;int y;scanf("%d", &te);while(te--){scanf("%d", &n);for(i = 0; i < 3; i++){a[i] = 0;}for(i = 0; i < n; i++){scanf("%d %d", &x, &y);if(y > a[x - 1]){a[x - 1] = y;}}for(i = 0; i < 3; i++){if(a[i] != 0){printf("%d %d\n", i + 1, a[i]);}}}}
