We’ll explore two key approaches to merge two sorted linked lists into a single sorted list: ✅ Iterative Approach Learn how to merge two linked lists step-by-step using a dummy node and loop-based logic. ✅ Recursive Approach Understand the elegant recursive solution that breaks the problem into smaller subproblems — great for clean and readable code. 📌 In this video, you'll learn: How both approaches work with dry-run examples When to use iterative vs recursive approach Time and space complexity analysis Edge case handling (empty lists, duplicates, etc.) Whether you're preparing for interviews or improving your data structures foundation, this video will help you master one of the most fundamental linked list problems. #LinkedList #CodingInterview #MergeSortedLists #Leetcode #RecursiveSolution #IterativeSolution #DataStructures #DSA #JavaProgramming #ProblemSolving #CTOBhaiya Your queries: merge two sorted lists leetcode merge lists linked list interview questions merge linked list iterative merge linked list recursive data structures linked list coding interview linked list recursive vs iterative leetcode linked list problems merge two sorted linked list java CHAPTERS 0:00 Introduction 1:17 Iterative Approach 5:02 Live Coding of Iterative Approach 7:40 Time & Space Complexity of Iterative Approach 8:21 Intuition of Recursive Approach 13:45 Live Coding of Recursive Approach 16:24 Time & Space Complexity of Recursive Approach 17:00 Conclusion =========================== ➡️ Connect with me: LinkedIn : https://www.linkedin.com/in/anuj-kumar-a-k-a-cto-bhaiya-on-youtube-9a188968 Telegram Channel : https://t.me/ctobhaiya_tg Instagram: https://www.instagram.com/ctobhaiya ===========================
