In computer science, k-way merge algorithms or multiway merges are a specific type of sequence merge algorithms that specialize in taking in k sorted lists and merging them into a single sorted list. These merge algorithms generally refer to merge algorithms that take in a number of sorted lists greater than two. … See more A 2-way merge, or a binary merge, has been studied extensively due to its key role in merge sort. An example of such is the classic merge that appears frequently in merge sort examples. The classic merge outputs the data … See more The k-way merge problem consists of merging k sorted arrays to produce a single sorted array with the same elements. Denote by n the total number of elements. n is equal to the size of the output array and the sum of the sizes of the k input arrays. … See more k-way merges are used in external sorting procedures. External sorting algorithms are a class of sorting algorithms that can handle massive amounts of data.

WebTime Complexity of Merge Sort in C#: The Merge Sort Algorithm is a recursive algorithm. The array of size N is divided into the maximum of logN parts, and the merging of all the subarrays into a single array takes O(N) time. Hence in all three cases (worst, average, best), the time complexity of Merge sort is O(nlogn). Algorithm for C# Merge Sort: WebJordan Zimmerman's k-way merge (Java).
