2、比赛的时候居然想了一个小时，才意识到是3*3字符的含义，纠结，好在一遍AC了

题目：

• [1219] Time

• 时间限制: 1000 ms　内存限制: 131072 K
• 问题描述
• Digital clock use 4 digits to express time, each digit is described by 3*3 characters (including”|”,”_”and” “).now given the current time, please tell us how can it be expressed by the digital clock.
  
• 输入
• There are several test cases.
  Each case contains 4 integers in a line, separated by space.
  Proceed to the end of file.
• 输出
• For each test case, output the time expressed by the digital clock such as Sample Output.
• 样例输入

• 1 2 5 6
  2 3 4 2

• 样例输出

•     _  _  _ 
    | _||_ |_ 
    ||_  _||_|
   _  _     _ 
   _| _||_| _|
  |_  _|  ||_ 

• 提示

• The digits showed by the digital clock are as follows:
     _  _     _  _  _  _  _  _ 
   | _| _||_||_ |_   ||_||_|| |
   ||_  _|  | _||_|  ||_| _||_|
