Please create code and explain how you solved each problem Please solve the following problems: 1. Given a number, return a sum of the digits (for instance, 498 = 21). 2. Given a list, remove duplicate values from the list. Do not convert the list to a set to do this. For instance, [7, 4, 3, 2, 3, 6, 3, 1) would return [7, 4, 3, 2, 6, 1] 3. Given a list, return all possible subsets of the list. For instance, [7, 3, 1] would return [[7], [3), [1], [7.3], [7, 1), (1, 3), and [7, 3, 1]]. Order does not matter here. 4. Create a function that sorts a list. Use recursion.
