public class MergeX extends Object
TheMergeX
class provides static methods for sorting an array using an optimized version of mergesort.In the worst case, this implementation takes Θ(n log n) time to sort an array of length n (assuming comparisons take constant time).
This sorting algorithm is stable. It uses Θ(n) extra memory (not including the input array).
For additional documentation, see Section 2.2 of Algorithms, 4th Edition by Robert Sedgewick and Kevin Wayne.
