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
