根据华容道的划分，将不同个字进行了编码，假设最小单位为一个方格（如下图左下角的小兵）

华容道的图形编码规则如下：

总共三位，

第一位；竖向两个单位的以 2 开头，曹操以 4 开头，横向两个单位的以 3 开头，一个单位的一 1 开头

第二位：同类型单位的编号，如曹操只有 1，小兵则分别为 11x,12x,13x,14x

第三位：方向编码，从上到下，从左到右编码为 1,2,3,4，如果没有则跳过，如左上角竖向两个单位的则表示为:211,213。

所以上图的图形编码可以如下表示（000 只是为了看起来方便）：

{211,401,402,241},

{213,403,404,243},

{221,311,312,251},

{223,111,121,253},

{131,000,000,141}

运行后，需要输入三位数，第一位是格子类型，第二位是同类型的编号（前两位就是要移动的小兵编码的前两位），第三位为方向，上下左右依次编码为 1、2、3、4，比如我要 111 这个小兵向下移动，则输入 112

每次输入就是打印出数组当前状况。
