Question

#include <iostream>
using namespace std;
struct Point{
    int x1,y1;
    int x2,y2;
    int ceil;//窗口编号
};
const int n=15;
Point a[n];
int main(){
    int N,M,j;
    cin>>N>>M;
    for(int i=0;i<N;++i){
        cin>>a[i].x1>>a[i].y1>>a[i].x2>>a[i].y2;
        a[i].ceil=(i+1);
    }//初始化
    for(int i=0;i<M;++i){
        bool flag=false;
        int x,y;
        cin>>x>>y;
        for(j=0;j<N;++j){
            if(x<=a[j].x2&&x>=a[j].x1&&y<=a[j].y2&&y>=a[j].y1)
                            flag=true;
            else
                break;
        }
        if(flag)
            cout<<a[j-1].ceil<<endl;
        else
            cout<<"IGNORED"<<endl;
        if(j-1==N-1);//本身在顶层
        else{
            Point temp=a[j-1];
            for(int k=j-1;k<N-1;++k)
                a[k]=a[k+1];
            a[N-1]=temp;
        }
    }
    return 0;
}
