I'm struggling to get my list to overlap and delete duplicates. I need help please and I'm suppose to implement this using python

First you ill ask user to input two lists. The input can be numbers or strings and you can assume there is no duplicate values. The program will then perform the following operations on two lists 1. Define a new list that contains all the overlapping elements between two lists 2. Define a new list that contains all the elements resulting from subtracting the second list from the first one For e.g.: List1 = [1, 2, 3, 5] List2 [2,3, 4, 10, 9] Overlapping list = [2,3] Subtraction list = [1,5] For this lab, you are expected to organize everything in functions. You will have a main0 functionality & Two other user defined functions to perform the overlap and subtraction operation. .You are not expected to use built-in functions that perform the above defined tasks directly. Of course you are allowed to use any built-in keywords like for, in, any conditionals etc and regular built in functions like print, raw_input and so on. 1. Suppose your list contains duplicate elements, write another user-defined function to remove the duplicates from the lists and then perform the overlap and subtraction operations. For e.g List1a", 'b','a", "e", "f] Then after removing the duplicates it should be: [ab', 'e, T]
