Solution: Palindrome Linked List
Explore how to check if a linked list is a palindrome by using fast and slow pointers to find the middle, reversing the second half for comparison, and then restoring the list. Understand each step to maintain the original structure while efficiently verifying the palindrome property with O(n) time and O(1) space complexity.

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.
