但为什么这个又是错的
```
#include<iostream>
#include<cstdio>
using namespace std;
#define N 10050
struct range
{
int a;
int b;
int lx;
int ly;
} p[N];
int x,y;
bool isin(int a,int b,int lx,int ly){
if(x>=a && x<=a+lx && y<=b && y>=b-ly+1) return true;
return false;
}
int n;
int main()
{
scanf("%d",&n);
for(int i=1;i<=n;i++)
scanf("%d%d%d%d",&p[i].a,&p[i].b,&p[i].lx,&p[i].ly);
scanf("%d%d",&x,&y);
int i=n;
for(i=n;i>=1;i--)
if(isin(p[i].a,p[i].b,p[i].lx,p[i].ly)){
printf("%d",i+1);
return 0;
}
printf("%d",-1);
return 0;
}
```
