Solution: Palindrome Linked List
Explore how to determine if a linked list is a palindrome without altering its original structure. Understand the step-by-step approach using fast and slow pointers to find the midpoint, reverse the second half, compare both halves for symmetry, and then restore the list. This lesson teaches a space-efficient, linear-time method to solve the palindrome linked list problem crucial for coding interviews.
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.
