List Length

List Length#

You will define a function combined_list_len that takes two parameters, both of which are lists and then combines them and returns the length of the combined list.

You can pick everything about the parameter name and how you write the body of the function, but it must be called combined_list_len.

The code challenge will call your combined_list_len function with many inputs and check that it behaves correctly on all of them. Your task is to only write the combined_list_len function.

Sample Input:

10 13 25 57
2 455 238
