AC了，比较出的问题

#include <iostream>
#include <algorithm>
#include <cstdio>
using namespace std;
int fen[21];
int main() {
    int n, m;
    double ans = 0;
    cin >> n >> m;
    for (int i = 0; i < n; i++) {
        int sum = 0;
        for (int j = 0; j < m; j++) {
            cin >> fen[j];
        }
        sort(fen, fen + m);
        for (int j = 1; j < m - 1; j++) {
            sum += fen[j];
        }
        if (sum / (m - 2.0)*1.0 > ans) {
            ans = sum / (m - 2.0)*1.0;
        }
    }
    printf("%.2lf", ans);
    return 0;
}
