Solution: Palindrome Linked List
Explore how to check whether a singly linked list is a palindrome by finding its midpoint with fast and slow pointers, reversing the second half, comparing both halves for equality, and restoring the list's original structure. This lesson guides you through an O(n) time and O(1) space complexity algorithm, helping you understand pointer manipulation and linked list reversal.

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.
