```cpp
#include<bits/stdc++.h>
using namespace std;
int cmp(double x,double y)
{
return x>y;
}
int main()
{
int n,m,a;
double sum[25];
double res[105];
cin>>n>>m;
for(int i=1;i<=n;i++)
{
for(int j=1;j<=m;j++)
{
cin>>sum[j];
}
sort(sum+1,sum+1+m);
for(int j=2;j<=m-1;j++)
{
res[i]+=sum[j];
}
res[i]/=m-2;
}
sort(res+1,res+n+1,cmp);
cout<<fixed<<setprecision(2)<<res[1];
return 0;
}
```
审题，去掉最高和最低的，取平均时也要m-2

@[daoling](/user/919172) 要求去掉一个最高分，去电一个最低分才去平均数，你并未去掉

每个人要减一个最高评分和最低评分
