You need to generate output file (for given validation input) and submit it there. use simple file IO for same.

Info

Then after validation completes(when you submit correct output) then it will ask you to submit output file to original input file (will be provided) along with your source code and you'll have only ~5 min to submit it !

You can use this C++ snippet for Input Output files

#include<bits/stdc++.h>
using namespace std;

int main(){
    freopen("input.txt","r",stdin);
    freopen("output.txt","w",stdout);
    
    // Your code goes here.

    return 0;
}

No, it will not cause any error if you don't want to remove lines then can use snippet below

Snippet

#ifndef ONLINE_JUDGE
    if (fopen("input.txt", "r"))
    {
        freopen("input.txt", "r", stdin);
        freopen("output.txt", "w", stdout);
    }
#endif

You can simply use < (input) and > (output) in command line while running your code. For example for c++ , it would be : ./a.out < input.txt > output.txt
