"""CSC110 Fall 2020 Assignment 2, Part 2: Conditional Execution

Instructions (READ THIS FIRST!)
===============================

This Python module contains your work for Part 2, Question 3. We have provided the functions
from the handout already, and you must NOT change these. Below them, we've provided one
sample (incomplete) unit test for each function. Your task is to complete these sample tests,
and then use the same format to create new ones to cover every possible execution path through
the three given functions.

You must use the provided structure for ALL unit tests. The only difference between your
tests should be which function is called, the argument values, and the expected return value.

Do not use hypothesis or property-based testing here.
