public class Shell extends Object
Shellclass provides static methods for sorting an array using Shellsort with Knuth's increment sequence (1, 4, 13, 40, ...). In the worst case, this implementation makes Θ(n3/2) compares and exchanges to sort an array of length n.
This sorting algorithm is not stable. It uses Θ(1) extra memory (not including the input array).

|Modifier and Type||Method and Description|
Reads in a sequence of strings from standard input; Shellsorts them; and prints them to standard output in ascending order.
Rearranges the array in ascending order, using the natural order.
public static void sort(Comparable a)
a- the array to be sorted
public static void main(String args)
args- the command-line arguments
