Solution: Find If a Doubly Linked List Is a Palindrome
Explore how to verify if a doubly linked list reads the same forwards and backwards. Learn to use two pointers starting at the head and tail to compare elements efficiently. This lesson teaches an O(n) time and O(1) space approach for palindrome checking in doubly linked lists, with detailed code examples and analysis.

Statement
Given the head of a doubly linked list, check whether the doubly linked list is a palindrome or not. Return TRUE if it is a palindrome; otherwise, return FALSE.
A palindrome is any string or sequence that reads the same from both ends. For example, 2002 is a palindrome.
Constraints:
Let n be the number of nodes in a doubly linked list.
