题意：

给定坐标，判断“王”可以移动的位置个数。

思路：

模拟吧，貌似是水题。

我竟然先做的第二题！！！结果无限次卡。。。。。。。要不要睡觉，明天两场积分赛！

CODE：

#include<stdio.h>
#include<cstring>
#include<algorithm>
using namespace std;
const int MYDD=1103;

char k[2];
int main() {
//	while(1) {
		scanf("%s",k);
		if(strcmp(k,"a1")==0||strcmp(k,"a8")==0||strcmp(k,"h1")==0||strcmp(k,"h8")==0)
			puts("3");
		else if(k[0]=='a'||k[0]=='h'||k[1]=='1'||k[1]=='8')
			puts("5");
		else    puts("8");
//	}
	return 0;
}
