Created by Aurelien Queffurust

Solve Later

Input A either an array or a vector (which can be empty)

Output B will be the same size as A . All elements of A equal to 13 (if any) must be replaced by zero.

For example:

A = [15 13 3]

output B is:

B= [15 0 3]

The difficulty in this problem is that the following commands FOR , WHILE , FIND and IND2SUB cannot be used.

A simple yet good problem. It made me think outside of using if and for loop.
