p1003求助 这题可以二维数组AC嘛

#include <bits/stdc++.h>
using namespace std;
int n, m,x,y,g,k,a,b;
int q[10000][10000];

int main()
{
	cin >> n;
	while (n--)
	{
		cin >> a >> b >> g >> k;// g=x轴长度  k=y轴长度
		a++, b++;
		for (int i=a;i<=a+g;i++)
		for (int j=b;j<=b+k;j++)
		{
			q[i][j] += 1;

		}

	}
	cin >> x >> y;
	if (q[x+1][y+1]>0)
	{
		cout << q[x+1][y+1];
	}
	else
	{
		cout << -1;
	}



}
