A palindrome is a word, phrase, number, or other sequence of characters that reads the same forward and backward, disregarding spaces, punctuation, and capitalization. Write a function isPalindrome that takes in a string s and returns a boolean value indicating whether s is a palindrome. Example: Input: s = "racecar" Output: true Input: s = "Hello" Output: false Input: s = "A man, a plan, a canal, Panama" Output: true Input: s = "12321" Output: true Note: The input string may contain spaces, punctuation, and capitalization, but they should be disregarded while checking for palindromes. An empty string is considered a palindrome.
