Shell Sort - Code of Code

WebShellsort is an optimization of insertion sort that allows the exchange of items that are far apart. The idea is to arrange the list of elements so that, starting anywhere, taking every h th element produces a sorted list. Such a list is said to be h -sorted. It can also be thought of as h interleaved lists, each individually sorted. [6] WebShellsort (also known as Shell sort or Shell's method) is an in-place comparison based sorting algorithm.
