```cpp
#include<bits/stdc++.h>
using namespace std;
int a[10001],n,m;
double q,ans,x,minn=1e9,maxx;
int main()
{
cin>>n>>m;
for(int i=1; i<=n; ++i)
{
for(int j=1; j<=m; ++j)
cin>>x,ans+=x;
minn=min(x,minn);
maxx=max(maxx,x);//有没有一种可能，这里应该在循环内
ans=ans-minn-maxx;
ans=1.0*ans/(1.0*(m-2));
if(ans>q) q=ans;
ans=0;
minn=1e9;
}
printf("%.2f",q);
return 0;
}
