Solution: Palindrome Linked List

Explore how to determine if a linked list is a palindrome by applying the fast and slow pointer technique. Learn to find the midpoint, reverse the second half for comparison, and restore the list to its original state without extra space usage.

We'll cover the following...

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.

  • 1≤1\leq n ≤500\leq500 ...
