Flatten Array

Welcome to Flatten Array on Exercism's Elixir Track. If you need help running the tests or submitting your code, check out HELP.md.

Instructions

Take a nested list and return a single flattened list with all values except nil/null.

The challenge is to take an arbitrarily-deep nested list-like structure and produce a flattened structure without any nil/null values.

For example:

input: [1,[2,3,null,4],[null],5]

output: [1,2,3,4,5]
