Problem
Write a loop that processes a string and returns true if the string is a palindrome and false if it is not. A string is a palindrome if it is spelled the same forward as it is backward. For example, the words "bob", "ABBA", "eevee", "a", "kayak" and "racecar" are all palindromes. EXTRA CREDIT: If you write the code to be case insensitive. This would make it so that words like "Bob" and "Anna" are marked as palindromes too.
