K-way merge in data structure

WebNov 19, 2024 · Seems like the best way to go is a k-way merge in increasingly larger sized blocks. A k-way merge seeks to build a sorted list, but we don't need it sorted and we don't need to consider each element. Instead we'll create a semi-sorted intervals. The intervals will be sorted, but only on the highest value. Web8. Write a program to read k Lists of names and merge them using k-way merge algorithm with k = 8.
