WebHow Does Shell Sort Work? Shell Sort works by comparing elements that are a certain distance apart in the array – this distance is known as the gap. It starts by comparing elements that are gap elements apart, then reduces the gap size, and repeats the process. The gap size is reduced until the gap is equal to one, at which point the array is ... WebJun 16, 2014 · The idea of ShellSort is to allow the exchange of far items. In Shell sort, we make the array h-sorted for a large value of h. We keep reducing the value of h until it becomes 1.
