From 0 to 1 Data Structures & Algorithms in Java - Shell Sort

The video tutorial explains Shell Sort, an algorithm that improves upon Insertion Sort by partitioning the list into sublists based on a chosen increment. Each sublist is sorted using a modified insertion sort, and the increment is gradually reduced to one, resulting in a nearly sorted list. The tutorial includes a visual example and discusses the complexity of Shell Sort, which varies depending on the increment values chosen. The algorithm is adaptive and requires no extra space, making it efficient for certain use cases.

What are the characteristics of the modified insertion sort used in Shell sort?

Discuss the challenges in determining the best increment value for Shell sort.
