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

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

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.

Hint:

The digits showed by the digital clock are as follows:

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

初见本题，想的思路是编写一个函数，其中传递一个参数，然后再函数中进行打印，最后感觉行不通，就算做出来了也是相当的复杂，在讨论区看见一种非常妙哉的方法。不过没有解释，写下个人理解，供大家参考和指教，我个人的理解是：将所有的数字先写出来，你就会发现每个拆分是最好的选择，然后创建一个二维数组，对每个数字的形状再数组中进行拆分，也就是三行，没有的地方就用空格代替。

#include<cstdio>
    #include<string>
    #include<iostream>
    using namespace std;
    
    string s[10][3] = {
       {" _ ","| |","|_|"},{" ", " |", " |"},{" _ ", " _|", "|_ "},{" _ ", " _|", " _|"},{" ", "|_|", " |"},
    {" _ ", "|_ ", " _|"},{" _ ", "|_ ", "|_|"},{" _ ", " |", " |"},{" _ ", "|_|", "|_|"},{" _ ", "|_|", " _|"}};
    
    int main() {
    int a, b, c, d;
    while (~scanf("%d%d%d%d", &a, &b, &c, &d)) {
    for (int i = 0; i < 3; i++) {
    cout << s[a][i] << s[b][i] << s[c][i] << s[d][i] << endl; 
    }
    }
    return 0;
    }
