表示不知道为什么就只能AC两个，找不出来错
```cpp
#include <iostream>
#include <cstdlib>
using namespace std;
//FILE *fin, *fout;
int main()
{
//fin=fopen("carpet.in","r");
//fout=fopen("carpet.out","w");
int n;
//fscanf(fin,"%d",&n);
scanf("%d",&n);
int *a;
a=new int[4*n]();
//int a[40002];
for(int i=0; i<4*n; i++) {
//fscanf(fin,"%d",&a[i]);
scanf("%d",&a[i]);
}
int x,y;
int last=-1;
//fscanf(fin,"%d%d",&x,&y);
scanf("%d%d",&x,&y);
for(int i=0; i<n; i++) {
if(x>=a[4*i+0] && x<=a[4*i+2]+x
&& y>=a[4*i]&& y<=a[4*i+3]) {
last=i+1;
}
}
//fprintf(fout,"%d",last);
printf("%d",last);
return 0;
}
```
