Welcome to LeetCode LevelUp!

In today’s video, we tackle LeetCode Problem 206: Reverse Linked List, a key problem in understanding linked lists and a popular topic in coding interviews. Using Java, we’ll solve this problem with a time complexity of O(n) and space complexity of O(1), efficiently reversing a singly linked list.

We cover:
Whiteboard walkthrough: A step-by-step explanation of the problem and the optimal approach.
Problem Introduction and Edge Cases: Identifying crucial edge cases like an empty list or a single-element list, and how to handle them.
Code Implementation: A live Java coding session to reverse the list using a while loop and pointer manipulation.
