n this video, I walk through LeetCode 23: Merge K Sorted Lists using a Divide and Conquer approach in JavaScript.
Instead of using a Min Heap, we iteratively merge pairs of linked lists until only one remains. This method achieves the same efficient time complexity as the heap-based solution — O(N log k) — without needing any additional data structures.
If you're prepping for coding interviews and want a clean, readable way to solve this problem in JavaScript, this one's for you.
What You'll Learn:
✅ How to merge two sorted linked lists
✅ How to scale that to K lists efficiently
✅ Why this method works like merge sort
✅ Time & space complexity breakdown
