Day26-Nested-Logic

Problem:

Objective
Today's challenge puts your understanding of nested conditional statements to the test. You already have the knowledge to complete this challenge, but check out the Tutorial tab for a video on testing!

Task
Your local library needs your help! Given the expected and actual return dates for a library book, create a program that calculates the fine (if any). The fee structure is as follows:

If the book is returned on or before the expected return date, no fine will be charged (i.e.: fine=0).
If the book is returned after the expected return day but still within the same calendar month and year as the expected return date,
fine = 15 Hackos x (the number of days late).
If the book is returned after the expected return month but still within the same calendar year as the expected return date,
the = 500 Hakos x (the number of months late).
If the book is returned after the calendar year in which it was expected, there is a fixed fine of 10000 Hackos.
