Question #1: Testing the Palindrome Function

A palindrome is a word, phrase, number, or other sequence of characters which reads the same backward as forward, such as madam or taco cat or racecar.

Imagine someone has developed a function is_palindrome( input_string ) that checks if the input string is a palindrome and returns a boolean True/False.

Your task is to test this function (do not write code for the function). Create a list of input strings and expected results to thoroughly test this function:

For example:

racecar -> True

abc -> False

Document any assumptions you make.
