这个代码可是坑死我了，昨晚上写了20分钟写完的，这么水的一个题，坑了我一天，还是瑞哥WCR的源码，当输入非法字符的时候，run了一次发现了不可预知的问题。

#include <stdio.h>
#include <string.h>
#define N 10
#define Ns 100
int main()
{
char puzzle[N][N];
char s;
char c;
int u=0;
while(1)
{
int i,j,k1,k2,wrong=0;
for(i=0;i<5;i++)
for(j=0;j<6;j++)
{
puzzle[i][j]=getchar();
if(puzzle[i][j]=='Z')
goto END;
if(puzzle[i][j]==32)
{
k1=i;
k2=j;
}
}
if(u)
printf("\n");
for(i=0,s=getchar();s!='0';)
{
if(s==10)
{
s=getchar();
continue;
}
if(s=='A')
{
if(k1>0)
{
puzzle[k1][k2]=puzzle[k1-1][k2];
k1=k1-1;
puzzle[k1][k2]=32;
}
else
wrong=1;
}
