求助大佬

#include<iostream>
using namespace std;
int main() {
	int n;
	cin >> n;
	int a[1000], b[1000], c[1000], d[1000];
	for (int i = 1; i <= n; i++) {
		cin >> a[i] >> b[i] >> c[i] >> d[i];
	}
	int x, y;
	cin >> x >> y;
	for (int i = n; i >=1 ; i--) {
		if (x >= a[n] && x <= a[n] + c[n])
			if (y >= b[n] && y <= b[n] + d[n]) {
				cout << i;
				return 0;
			}
	}
	cout << -1;
	return 0;
}
