Recap - Number Processor

Write a function named process_numbers that takes an array of whole numbers, numbers, and returns a new array:

1. First drop every number that is 0 or negative.
2. Then double the even numbers that are left and triple the odd ones.

Keep the original order. Use filter() and map(), and no loop. For example, process_numbers([-4, 0, 5, 2, 8, -3, 7]) returns [15, 4, 16, 21].

The tests call process_numbers() themselves. Do not call it, and do not print anything.
