此题思想
根据初始点的位置,向上向右扩展出一个范围,然后进行递推即可。
#include<cstdio>
#include<iostream>
using namespace std;
int main() {
int i, a[10001][4], n, x, y, f = -1;
cin >> n;
for (i = 1; i <= n; i++) {
cin >> a[i][0] >> a[i][1] >> a[i][2] >> a[i][3];
a[i][2] += a[i][0];
a[i][3] += a[i][1];
}
cin >> x >> y;
for(i = n; i >= 1; i--) {
if(a[i][0] <= x && a[i][1] <= y && a[i][2] >= x && a[i][3] >= y)
{
cout << i;
f = 1;
break;
}
}
if (f == -1) {
cout << f << endl;
}
return 0;
}
