#include<bits/stdc++.h>

    cin>>n;
    for (int i = 1;i<=n;i++){
        cin>>a[i];
        if (a[i]>maxn){
            maxn = a[i];
            maxi = i;
        }
        if (a[i]<minn){
            minn = a[i];
            mini = i;
        }

    }
    for (int i = 1;i<=n;i++){
        if (i!=maxi && i!=mini){
            sum+=a[i];
        }
    }
    printf("%.2lf",1.00*sum/(n-2.00));
}

你的代码的改进版，可AC（你看了应该就知道你错哪了）

求关

@KarmaticEnding 没有......

@hp2024022

你还没有找出输入的最大值和最小值就将sum+=a;

也就是说输入的这个数只要没有之前输入最大的数大、没有之前输入最小的数小就将 sum+=a;所以不对

@ZMY_123 谢谢
