Palindrome After Cleaning | Dataford Interview Questions

Implement an algorithm to detect if a given string is a palindrome after removing non-alphanumeric characters.

Define a palindrome check as case-insensitive. Return True if the remaining characters read identically forward and backward, or False otherwise. Implement is_palindrome(s), where s is a string and the return value is a boolean.

Constraints

0 <= len(s) <= 2 * 10^5
s may contain letters, digits, whitespace, punctuation, and Unicode characters
Alphabetic comparisons are case-insensitive
An empty filtered string is a palindrome

Function Signature

def is_palindrome(s):
