求助，输出对的，但全wa

#include <bits/stdc++.h>
using namespace std;
int n,pi,x,maxn=-1,minn=100;
int main() {
    float tot;
    cin>>n;
    for(int i=1;i<=n;i++){
        cin>>x;
        if(x>maxn) maxn=x;
        if(x<minn) minn=x;
        pi+=x;
    }
    tot=pi-maxn-minn;
    printf("%.2 f",tot/(n-2));
    return 0;
}
