Solution: Find If a Doubly Linked List Is a Palindrome

Understand how to verify if a doubly linked list forms a palindrome by using two pointers at the start and end, comparing node values while traversing inward. This lesson guides you through implementing the solution with efficient time and space complexity, reinforcing your linked list manipulation skills.

We'll cover the following...

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.

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.

  • 11 \leq ...
