poj1656 （寂寞題）

出題人好寂寞啊，當然做題的更寂寞，這種題以後要少做.........

#include <stdio.h>#include <string.h>int color[101][101];void paint(int x,int y,int L,int paint_color){int i;int j;for(i=x;i<x+L;i++){for(j=y;j<y+L;j++){color[i][j]=paint_color;}}}int test(int x,int y,int L){int count=0;int i;int j;for(i=x;i<x+L;i++){for(j=y;j<y+L;j++){if(color[i][j]){count++;}}}return count;}int main(void){int N;scanf("%d",&N);int x;int y;int L;char command[5];memset(color,0,sizeof(color));while(N--){scanf("%s %d %d %d",command,&x,&y,&L);if(command[0]=='W'){paint(x,y,L,0);}else if(command[0]=='B'){paint(x,y,L,1);}else{printf("%d\n",test(x,y,L));}}return 0;}
