Challenge: Find If a Doubly Linked List Is a Palindrome

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.

• $1 \leq$ n $\leq 500$

• $1 \leq$ node.data $\leq 100$
