public class Heap extends Object
TheHeap
class provides a static method to sort an array using heapsort.This implementation takes Θ(n log n) time to sort any array of length n (assuming comparisons take constant time). It makes at most 2 n log2 n compares.
This sorting algorithm is not stable. It uses Θ(1) extra memory (not including the input array).
For additional documentation, see Section 2.4 of Algorithms, 4th Edition by Robert Sedgewick and Kevin Wayne.
