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

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

1 2 5 6

2 3 4 2

    _  _  _

  | _||_ |_

  ||_  _||_|

 _  _     _

 _| _||_| _|

|_  _|  ||_ 

The digits showed by the digital clock are as follows:

签到题，理清楚就好，代码如下

 #include <iostream>

 #include<stdio.h>

 using namespace std;

 int num[];

 char s1[][]={

     {' ','_',' '},{' ',' ',' '},{' ','_',' '},{' ','_',' '},

     {' ',' ',' '},{' ','_',' '},{' ','_',' '},{' ','_',' '},

     {' ','_',' '},{' ','_',' '}

     };

     char s2[][]={

     {'|',' ','|'},{' ',' ','|'},{' ','_','|'},{' ','_','|'},

     {'|','_','|'},{'|','_',' '},{'|','_',' '},{' ',' ','|'},

     {'|','_','|'},{'|','_','|'}

     };

     char s3[][]={

     {'|','_','|'},{' ',' ','|'},{'|','_',' '},{' ','_','|'},

     {' ',' ','|'},{' ','_','|'},{'|','_','|'},{' ',' ','|'},

     {'|','_','|'},{' ','_','|'}

     };

 int main()

 {

    while(~scanf("%d",&num[]))

    {

        for(int i=;i<;i++)scanf("%d",&num[i]);

             for(int i=;i<;i++)

            for(int j=;j<;j++)

            {

                printf("%c",s1[num[i]][j]);

            }

            printf("\n");

             for(int i=;i<;i++)

            for(int j=;j<;j++)

            {

                printf("%c",s2[num[i]][j]);

            }

            printf("\n");

             for(int i=;i<;i++)

            for(int j=;j<;j++)

            {

                printf("%c",s3[num[i]][j]);

            }

            printf("\n");

    }

     return ;
