My issue

include <bits/stdc++.h>
include
using namespace std;
using namespace chrono;
define ll long long
void solve(){
ll n;cin>>n;
ll a[n];
for(int i=0;i<n;i++) cin>>a[i];
sort(a,a+n);
int minm=a[0],maxm=a[n-1];
int minimum=min(minm,maxm),maximum=max(minm,maxm);
cout<<minimumminimum<<" "<<maximummaximum<<“\n”;
}
please debug these code?

    sort(a,a+n);
    int minm=a[0],maxm=a[n-1];
    int minimum=min(minm,maxm),maximum=max(minm,maxm);
    cout<<minimum*minimum<<" "<<maximum*maximum<<"\n";
