Solve: Remove Empty and Null from List (with assert)

Created By: Justin Maier

/ Version: 2024.11.0

Write a void method named cleanList that takes a List<String> as an argument and modifies the list to remove all elements that are either the empty String ("") or null.

Remember that you can use remove to remove elements from a List, though you should be careful that you do not remove elements from a List while you are iterating over it (with a for loop, for example).

You should assert that the List argument is not null.
