K-way merge operation
WebDec 11, 2024 · K-Way Merge Algorithms -way merge algorithms, also known as multiway merges, are algorithms that take -sorted lists as input and produce one sorted list as an output with size equal to the sum of sizes of all input arrays. The term “ -way merge algorithms ” refers to merging approaches that accept more than two sorted lists: Web1 I need to implement a function which does a k-way merge sort on an unsorted array or integers. The function takes in two parameters, an integer K, which is the "way" of the sort …

It distributes the input into k streams by repeatedly reading a blockof input that fits in memory, called a run, sorting it, then writing it to the next stream. It merges runs from the k streams into an output stream.
