题目大意：5x5的方格，内有一空格，通过上下左右移动使空格位置不断变换。

分析：强行做就好，题目很水，输入的时候需要仔细考虑下，而且输出格式坑了些，它样例给的输出格式就不标准。。。。。

AC Code：

#include <algorithm>
    #include <iostream>
    #include <cstdlib>
    #include <cstring>
    #include <cstdio>
    #include <cmath>
    
    using namespace std;
    
    char maps[5][7];
    char cmd[1001];
    
    int main()
    {
        int cases = 0;
        while (gets(maps[0])) {
            if (maps[0][0] == 'Z') break;
            for (int i = 1 ; i < 5 ; ++ i)
                gets(maps[i]);
            int b_x = 0,b_y = 0;
            for (int i = 0 ; i < 5 ; ++ i)
                for (int j = 0 ; j < 5 ; ++ j)
                    if (maps[i][j] == ' ') {
                        b_x = i;b_y = j;
                        break;
                    }
            int count = 0;
            while (~scanf("%c",&cmd[count]))
                if (cmd[count] != '0') count ++;
                else break;
            cmd[count] = 0;getchar();
    
            int flag = 0,x = b_x,y = b_y;
            for (int i = 0 ; cmd[i] ; ++ i) {
                switch(cmd[i]) {
                    case 'A':   x = b_x-1;y = b_y; break;
                    case 'B':   x = b_x+1;y = b_y; break;
                    case 'L':   x = b_x;y = b_y-1; break;
                    case 'R':   x = b_x;y = b_y+1; break;
                }
    
                if (x < 0 || x > 4 || y < 0 || y > 4) {
                    flag = 1;break;
                }else {
                    maps[b_x][b_y] = maps[x][y];
                    maps[x][y] = ' ';
                    b_x = x; b_y = y;
                }
            }
    
            if (cases ++) printf("\n");//注意这里的换行
            printf("Puzzle #%d:\n",cases);
    
            if (flag)
                printf("This puzzle has no final configuration.\n");
            else {
                for (int i = 0 ; i < 5 ; ++ i) {
                    printf("%c",maps[i][0]);
                    for (int j = 1 ; j < 5 ; ++ j)
                        printf(" %c",maps[i][j]);
                    printf("\n");
                }
            }
        }
        return 0;
    }
