Palindrome Checker

You are given a string s and you need to determine whether it is a palindrome.

A palindrome is a string that reads the same backward as forward. For example, "racecar", "a", and "abba" are palindromes, while "hello" and "a bcc ba" are not.

Please note that the check is case-sensitive and even whitespace is considered in the comparison.
