Palindrome Linked List

Understand how to verify whether a linked list is a palindrome by applying the fast and slow pointers method. This lesson helps you maintain the original linked list structure while efficiently checking for symmetry, enhancing your knowledge of linked list traversal and algorithm optimization.

Statement

Given the head of a linked list, your task is to check whether the linked list is a palindrome or not. Return TRUE if the linked list is a palindrome; otherwise, return FALSE.

Note: The original structure of the linked list must remain unchanged before and after the checking process.

Constraints:

Let n be the number of nodes in a linked list.
