Recognize Known Commands

Extend Monty 1 code to work as follows:

It recognizes the list command and responds with a fixed message.

It recognizes the exit command and exits the program if user confirms.

For all other inputs, it responds with a fixed error message.

A sample session is given below.

You are highly encouraged to give the software a different name (i.e., not Monty), define your own command formats (e.g., show instead of list), and even a different personality (e.g., you can make its questions/responses sound similar to a popular video game character). Differentiating your software in those ways will reduce the risk of plagiarism concerns.

>>> Hello, my name is Monty >>> What can I do for you? list >>> Nothing to list >>> What can I do for you? foo >>> OOPS! Unknown command >>> What can I do for you? exit >>> Are you sure? y/n n >>> What can I do for you? exit >>> Are you sure? y/n y >>> Bye!
