added a palindrome helper and positive tests. I need to determine if a single digit is a palindrome.... it technically is, but I want to know the real definition of palindrome
addition of negative tests for palindromic ints
single digits are not palindromes... additional test case.... first stab at problem4 was off and poorly designed
gave up on optimization and took the occam's razor approach.... problem 4 completed.
