Consider a first list as the Original Version of a List, then add 3 new values on that list asking the user and overwrite 1 of them. Then, create a second list as the New Version List after changes. Using operations with sets, your program should print the list of changes between these two versions, listing: • the elements that have not changed • the new elements • the elements that have been removed Example: originalList [1, 2, 5, 6, 9] newList = [1, 2, 8, 6, 9, 10, 11, 14] =task 12.2
