Class QuickX

java.lang.Object

edu.princeton.cs.algs4.QuickX

public class QuickX
extends java.lang.Object

The QuickX class provides static methods for sorting an array using an optimized version of quicksort (using Hoare's 2-way partitioning algorithm, median-of-3 to choose the partitioning element, and cutoff to insertion sort).

For additional documentation, see Section 2.3 of Algorithms, 4th Edition by Robert Sedgewick and Kevin Wayne.
