solution

总成绩= （老师成绩 + 同学去掉最高分去掉最低分的平均分）/2，其中总成绩四舍五入取整

#include<iostream>
#include<algorithm>
using namespace std;
int main(){int n, m, worst, better, sum, g, x, cnt;scanf("%d%d", &n, &m);for(int i = 0; i < n; i++){scanf("%d", &g);worst = m + 1;better = -1;sum = cnt = 0;for(int j = 0; j < n - 1; j++){scanf("%d", &x);if(x >= 0 && x <= m){cnt++;sum += x;worst = min(worst, x);better = max(better, x);}}printf("%d\n", ((sum - worst - better) / (cnt - 2) + g + 1) / 2);}return 0;
}
