测试点5WA了,看了数据也是和别的数据一样是10000地毯

先贴代码,求大佬看看

#include <iostream>
using namespace std;

const int N = 4e4+10;
int q[N];

int main()
{
	int n;cin>>n;
	for(int i = 0; i < n*4; i ++)
		cin>>q[i];
	int x,y;
	cin>>x>>y;
	int res = 0;
	for(int i = 0; i < n*4; i += 4)
	{
		int x1 = q[i],y1 = q[i + 1],x2 = q[i + 2], y2 = q[i + 3];
		if(x1 <= x && x2 >= x && y1 <= y && y2 >= y)res = i/4+1;
	}
	if(!res)res = -1;
	cout << res;
}

代码应该比较简单的,但是确实是找不到错误
