Solution: Palindrome Linked List

Explore how to solve the palindrome linked list problem by using fast and slow pointers to find the middle, reversing the second half for comparison, and restoring the original list. Understand an efficient O(n) time and O(1) space algorithm that preserves the linked list structure throughout the process.

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 ...
