Solution: Merge K Sorted Lists
Explore how to merge multiple sorted linked lists efficiently using a divide-and-conquer method. Understand the process of pairwise merging with two pointers, the use of a dummy node for simplification, and how to optimize performance to achieve O(n log k) time and O(1) space complexity. This lesson helps you apply these techniques to solve the merge K sorted lists problem effectively.

Statement
You are given an array, lists, containing k singly linked lists. Each of these linked lists is individually sorted in ascending order.
Your task is to merge all k linked lists into a single sorted linked list in ascending order and return the merged list.
