NEUOJ Problem48 Problem Description
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 _ _ _ | || |_ ||_ ||| _ _ _ | ||| | |_ | ||
