啦啦啦！题目做出来，开心😊

#include<iostream>
using namespace std;
int main(){
    int n;
    cin>>n;
    int a[n],sum=0;
    double pingjunfen=0.0;
    for(int i=0;i<n;i++){
        cin>>a[i];
        sum+=a[i];
    }
    pingjunfen=sum*1.0/n;
    for(int i=0;i<n;i++){
        if(a[i]<=pingjunfen)cout<<a[i]<<' ';
    }
    return 0;
}
