Solution: Palindrome Linked List

Understand how to verify if a singly linked list is a palindrome by using two-pointer techniques. This lesson teaches you to find the midpoint, reverse the second half in place, compare both halves, and then restore the original list. Gain skills in fast and slow pointer usage for linked list manipulation while maintaining the list structure.

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 ...
