LeetCode - 61 | Rotate Linked List | Divide and Combine Approach

LeetCode 61 - Rotate List | C++ In this video, we solve LeetCode 61: Rotate List and explore two different approaches to the problem. Methods Covered Method 1: Insert Head (rotate one step at a time) Intuitive approach to understand the rotation process. Time Complexity: O(n²) Space Complexity: O(1) Method 2: Divide & Combine (Optimal) Find the correct split point based on k. Divide the linked list into two parts. Reconnect the list to obtain the required rotation. Time Complexity: O(n) Space Complexity: O(1) In this video Problem intuition Edge cases (k is greater than n, empty list, single-node list) Step-by-step implementation in C++ Complexity analysis and comparison of both approaches If you have questions or alternative approaches, feel free to share them in the comments.
