Solution: Palindrome Linked List
Explore a step-by-step approach to check if a linked list is a palindrome by finding its midpoint with fast and slow pointers, reversing the second half, comparing both halves, and restoring the list to its original form. Understand the time and space efficiency of this technique to apply it confidently in coding interviews.

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.
