还有，cin和scanf不要混用
```cpp
#include <bits/stdc++.h>
using namespace std;
int n,m,b;
int p[110];
int main(){
cin>>n>>m;
double a = 0,b2 = 0,c = 0;
b = m - 2;
for(int i = 1;i <= n;i++){
for(int j = 1;j <= m;j++) cin>>p[j];
sort(p + 1,p + 1 + m);
for(int sum = 2;sum < m;sum++) b2 += p[sum];
a = b2 / b;
if(a > c) c = a;
a = 0;
b2 = 0;
}
cout <<fixed<<setprecision(2)<<c;
return 0;
}
```
