答案 7.00
输出 10.00

sort排序出错了，拿个max记录最大值是可以ac的,具体什么原因我也不知道
```cpp
#include <bits/stdc++.h>
using namespace std;
int n, m;
double average[25];
double a[105];
int main() {
cin >> n >> m;
double max = 0;
for (int i = 0; i <= n-1; i++) {
double s = 0;
for (int x = 0; x <= m-1; x++) {
cin >> a[x];
}
sort(a, a + m);
for (int k = 1; k <= m-2; k++) {
s = s + a[k];
}
average[i] = s / (m-2);//cout << average[i] << endl;
if(average[i] > max) max = average[i];
}
sort(average, average+n);
printf("%.2lf", max);
return 0;
}
```
