Solution: Find If a Doubly Linked List Is a Palindrome
Understand how to check whether a doubly linked list is a palindrome by using two pointers that compare nodes from both ends simultaneously. This lesson guides you through the logic and C++ implementation, highlighting time and space complexity to help you solve similar linked list problems in coding interviews.

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.
