d = float((sum(c)-max(c)-min(c))/(n-2))
print(round(d,2))

@[ytt02_11](/user/594967) 问题不出在编辑器或解释器上，你再看看题意，除 $3$ 只适用于样例。

C++代码
```cpp
#include<bits/stdc++.h>
using namespace std;
int a[1005];
int main(){
int n;
cin >> n;
for(int i=1;i<=n;i++) cin >> a[i];
sort(a+1,a+n+1);
a[1]=a[n]=0;
int sum=0;
for(int i=1;i<=n;i++) sum+=a[i];
printf("%.2f",1.0*sum/(n-2));
return 0;
}
```
