125. Valid Palindrome

#APPROACH : This code defines a function to check if a string is a palindrome by removing non-alphanumeric characters and comparing the reversed string.


class Solution:
    def isPalindrome(self, s: str) -> bool:
        # Convert to lowercase and remove non-alphanumeric characters
        s = ''.join(c.lower() for c in s if c.isalnum())
        # Check if s reads the same forward and backward
        return s == s[::-1]
