Solution: Valid Palindrome
Explore how to implement a validated palindrome checker using two pointers in Go. Understand how to traverse strings efficiently by skipping invalid characters and comparing characters case-insensitively, ultimately solving the problem with optimal time and space complexities.
Statement
Given a string, s, return TRUE if it is a palindrome; otherwise, return FALSE.
A phrase is considered a palindrome if it reads the same backward as forward after converting all uppercase letters to lowercase and removing any characters that are not letters or numbers. Only alphanumeric characters (letters and digits) are taken into account.
Constraints:
s.length...
