b累加的那层循环`i<n`应为`j<m`

现在的代码：
```cpp
#include <bits/stdc++.h>
using namespace std;
int main()
{
int n,m,a[10002]={};
double b=0,fen=0;
cin >> n >> m;
for (int i=1;i<=n;i++)
{
for (int j=1;j<=m;j++)
{
cin >> a[j];
}
sort (a+1,a+m+1);
for (int j=2;j<m;j++)
{
b+=a[j];
}
b/=(m-2);
if (b>=fen)
{
fen=b;
}
for (int j=1;j<=m;j++)
{
a[j]=0;
}
}
printf ("%.2f",fen);
return 0;
}
```
