Clean Palindrome Check
A phrase may contain spaces, commas, and mixed letter case, but those are just noise when checking a palindrome. Given a string s, consider only letters and digits. Ignore case, so A and a count as the same character. Return True if the cleaned string reads the same from left to right and right to left; otherwise, return False.
