没清空a数组
#include <bits/stdc++.h>
using namespace std;
int main(){
long long n,m,b;
cin>>n>>m;
vector<double>h;
for(int i=1;i<=n;i++){
vector<int>a;
for(int j=1;j<=m;j++){
cin>>b;
a.push_back(b);
}
sort(a.begin(),a.end());
double sum=0;
for(int i=1;i<m-1;i++){
sum=sum+a[i];
}
h.push_back(sum/(m-2));
}
sort(h.begin(),h.end());
cout<<fixed<<setprecision(2)<<h[n-1];
}
