Problem 824. Set the array elements whose value is 13 to 0
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.

this is a good problem
damn man!!! i just tore my head off to solve this then i figured there is a very very simple way to do that
A simple yet good problem. It made me think outside of using if and for loop.
