        根据题意求平均值，不过要去掉一个最高分和一个最低分。

#include <cstdio>//#define yangyuanint main(){#ifdef yangyuanfreopen("in", "r", stdin);#endif // yangyuan    int n;    while (scanf("%d", &n) != EOF){        int min, max, x, sum;        scanf("%d", &min);        sum = max = min;        for (int i = 1; i < n; i++){scanf("%d", &x);sum += x;            if (min > x)                min = x;            else if (max < x)                max = x;}        printf("%.2f\n", (double)(sum - min - max) / (n - 2));}    return 0;}
