Python Problem: Given two lists, make a function that merges these two lists in descending order. Your main program will allow the user enter two lists of numbers and end input with a blank line for list 1. You are not allowed to concatenate two lists into a new list and then call the built-in sort() function to sort the new list in descending order. But it is allowed to sort two lists in descending order before merge.

List 1: 1 3 3 6 List 2: 1 4 5 [6, 5, 4, 3, 3, 1, 1] List 1: 100 List 2: 1 13 [100, 3, 1, 1] List 1
