Merge K Sorted Lists | Approach 2 | Iterative Merge Approach (C++) | Optimised

In this video, we solve LeetCode 23 – Merge K Sorted Lists using an *iterative merging approach in C++*. Instead of collecting all values and sorting them, this method reuses the logic of Merge Two Sorted Lists and repeatedly merges lists one by one. This significantly improves efficiency compared to the brute force approach. Approach used in this video: • Start with the first list • Iteratively merge it with the next list using `mergeTwoLists()` • Continue until all K lists are merged into one sorted linked list This is a clean and intuitive strategy that builds directly on the classic *Merge Two Sorted Lists problem*. Topics covered in this video: Linked List manipulation Iterative merging technique Reusing helper functions Clean C++ implementation Time and Space Complexity discussion This is the second approach to solving the problem and improves over the brute force method.
