Learn how to use k-way merge for efficient data merging and finding k-th small elements.

Coding

The K-Way Merge pattern is an algorithmic strategy used to efficiently combine multiple sorted sequences into a single sorted result. By using a min-heap or priority queue to track the smallest elements among k sources, it ensures optimal merging performance across arrays, lists, or data streams.
