@[daishuohua](/user/872197) 这样写应该也可以
```cpp
#include<bits/stdc++.h>
using namespace std;
int a[25];
int maxb=0;
void start(int a[],int m)
{
int sum=0,minn=11,maxn=0;
for(int j=1;j<m;j++)
{
sum+=a[j];
minn=min(a[j],minn);
maxn=max(a[j],maxn);
}
maxb=max(sum,maxb);
}
int main()
{
int n,m;
cin>>n>>m;
for(int i=0;i<n;i++)
{
for(int j=0;j<m;j++)
{
cin>>a[j];
}
start(a,m);
}
printf("%.2lf",(double)maxb/(m-2));
return 0;
}
