Solution: Palindrome Linked List

Explore how to verify whether a linked list is a palindrome by mastering the fast and slow pointer technique. Learn to find the midpoint, reverse the second half, compare list halves, and restore the original structure, all while maintaining 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.

  • 11 \leq n 500\leq 500 ...
