Palindromic String Checker

Given a string S, determine whether it is a palindrome by considering only alphanumeric characters and ignoring cases. In other words, let \( \text{cleaned}(S) \) be the string obtained by removing all non-alphanumeric characters from S and converting all letters to lowercase. The string is a palindrome if and only if \( \text{cleaned}(S) = \text{reversed(cleaned}(S)) \).

For example, the string "A man, a plan, a canal, Panama" should be considered a palindrome.
