Solution: Merge K Sorted Lists
Explore how to merge k sorted linked lists into a single sorted list by using a divide-and-conquer method that pairs and merges lists efficiently. Understand the use of two pointers and a dummy node to streamline merging, and analyze the O(n log k) time complexity. This lesson equips you with a practical approach to solve the k-way merge problem effectively.
