本文介绍了一种使用3x3字符矩阵来表示数字的方法，并通过一个简单的C++程序演示了如何将四位数的时间显示为数字钟格式。每个数字由三行组成，每行四个字符，包括横线'_'、竖线'|'和空格。示例输入输出展示了如何用这种格式表示不同的时间。

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.

Input

There are several test cases.
Each case contains 4 integers in a line, separated by space.
Proceed to the end of file.

Output

For each test case, output the time expressed by the digital clock such as Sample Output.

Sample Input

1 2 5 6
2 3 4 2

Sample Output

    _  _  _ 
  | _||_ |_ 
  ||_  _||_|
 _  _     _ 
 _| _||_| _|
|_  _|  ||_

Hint

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

代码范例：
int main()
{
    int a,b,c,d;
    string s[10]= {" _ ","   "," _ "," _ ","   "," _ "," _ "," _ "," _ "," _ "};
    string t[10]= {"| |","  |"," _|"," _|","|_|","|_ ","|_ ","  |","|_|","|_|"};
    string w[10]= {"|_|","  |","|_ "," _|","  |"," _|","|_|","  |","|_|"," _|"};
    while(cin>>a>>b>>c>>d)
    {
        cout<<s[a]<<s[b]<<s[c]<<s[d]<<endl;
        cout<<t[a]<<t[b]<<t[c]<<t[d]<<endl;
        cout<<w[a]<<w[b]<<w[c]<<w[d]<<endl;
    }
    return 0;
}
