Help me in solving CNOTE problem

My issue

Why does adding the “break;” result in WA?

My code

#include <iostream>
using namespace std;

int main() {
	// your code goes here
	int t; cin>>t;
	while (t--)
	    int x, y, k, n; cin>>x>>y>>k>>n;
	    //needs x-y pages
	    int xy = x-y;
	    bool can = false;
	    for (int i = 0; i < n; i++)
	        int p, c; cin>>p>>c;
	        if (p >= xy && c <= k)
	            can = true;
	    can ? cout << "LuckyChef" : cout << "UnluckyChef";
	    cout << endl;
	return 0;

It results in WA because you are also taking input in that for loop. If you break, you will end up not taking the complete input for the current test case.
