A. 简单模拟

铺地毯：就是模拟

 1 #include<cstdio>
 2 #include<iostream>
 3 #define maxn 10000000
 4 using namespace std;
 5 
 6 struct parpet{
 7     int x1,x2,y1,y2;
 8 }list[maxn];
 9 
10 int n,a,b,c,d,ansx,ansy,ans;
11 
12 bool Judge(parpet &A,int x,int y){
13     return (A.x1 <= x)&&(x <= A.x2)&&(A.y1 <= y)&&(y <= A.y2);
14 } 
15 
16 int main(){
17     scanf("%d",&n);
18     for(int i = 0;i < n;i++){
19         scanf("%d%d%d%d",&a,&b,&c,&d);
20         list[i].x1 = a;
21         list[i].y1 = b;
22         list[i].x2 = a+c;
23         list[i].y2 = b+d;
24     }scanf("%d%d",&ansx,&ansy);
25     ans = -1;
26     for(int i = 0;i < n;i++){
27         if(Judge(list[i],ansx,ansy)) ans = i+1;
28     }
29     
30     printf("%d",ans);
31 } 

我第一眼居然是离散化
