这是什么玩意啊啊啊啊

#include <bits/stdc++.h>
using namespace std;
int main(){
    int n,ii,maxnum = 2,minnum = 11;
    double all;
    cin >> n;
    for (int i = 0; i < n; i++){
        cin >> ii;
        if (ii > maxnum){
            maxnum = ii;
            continue;
        }
        if (ii < minnum){
            minnum = ii;
            continue;
        }  
        all += ii;
   }
   n -= 2;
   all /= n;
   cout << fixed << setprecision(2) << all;
   return 0;
}

我觉得我的代码没问题啊~

但是

我只是蒟蒻，求助各位大佬
