P1003题——铺地毯

#include<stdio.h>
const int max = 1000 + 5;
int a[max],b[max],g[max],k[max];

int main(){
	int n,x,y;
	
	scanf("%d", &n);
	for(int i = 0;i < n;i ++){
		scanf("%d%d%d%d", &a[i], &b[i], &g[i], &k[i]);
	}
	scanf("%d%d", &x, &y);
	
	int answer = -1;
	for(int i = 0;i < n;i ++){
		if(x >= a[i] && y >= b[i] && x <= a[i] + g[i] && y <= b[i] + k[i]){
			answer = i + 1;
		}
	}
	
	printf("%d\n",answer);
	
	return 0;
}

样例都过了但是60分，求助
