```cpp
#include<bits/stdc++.h>
using namespace std;
int main(){
int n,m;
cin>>n>>m;
double ans=0;
for(int i=1;i<=n;i++){
int maxx=0,minn=0x7f7f7f7f,sum=0,x;
for(int j=1;j<=m;j++){
cin>>x;
sum+=x;
maxx=max(x,maxx);
minn=min(x,minn);
}
sum-=maxx+minn;
ans=max(ans,sum*1.0/(m-2));
}
printf("%.2f",ans);
return 0;
}
