Object Oriented Programming System (OOPs) is a programming model built on the perception of “objects” that contains data and methods. The major purpose of Object Oriented Programming is to increase the maintainability and flexibility of programs. Object Oriented Programming gets together data and its behavior (methods) in a single location (object) which makes it easier to understand.

Write the following function in Lisp: a function that takes one parameter that you can assume to be a symbol named after a day of the week (no need to check it), such as 'monday, and returns the symbol for the next day. For example, (next-day 'tuesday) should return the symbol 'wednesday. Implement this function with a complex conditional.
