Flatten Array
Take a nested list and return a single flattened list with all values except nil/null.
The challenge is to write a function that accepts an arbitrarily-deep nested list-like structure and returns a flattened structure without any nil/null values.
For Example
input: [1,[2,3,null,4],[null],5]
output: [1,2,3,4,5]
