Question

A simple software system for a library models a library as a collection of books
and patrons. A patron can have at most three books out on loan at any given time.
A book also has a list of patrons waiting to borrow it. Each book has a title, an
author, a patron to whom it has been checked out, and a list of patrons waiting for
that book to be returned. Each patron has a name and the number of books it has
currently checked out. Develop the classes Book and Patron to model these objects.
Think first of the interface or set of methods used with each class, and then choose
appropriate data structures for the state of the objects. Also, write a short script to
test these classes
