My code

#include <bits/stdc++.h>
#define ll long int
using namespace std;

int main() {
	// your code goes here
	int t;
	cin>>t;
	while(t--){
	    ll n,k;
	    cin>>n>>k;
	   
	}
	return 0;
}

@deepak_5047
In any row first element will be the size of the array and rest will be its elements.
Its mentioned in the input section that first element would be the size of the array.
