 edu.princeton.cs.algs4.Selection

public class Selection extends Object
TheSelection
class provides static methods for sorting an array using selection sort. This implementation makes ~ ½ n^{2} compares to sort any array of length n, so it is not suitable for sorting large arrays. It performs exactly n exchanges.This sorting algorithm is not stable. It uses Θ(1) extra memory (not including the input array).
For additional documentation, see Section 2.1 of Algorithms, 4th Edition by Robert Sedgewick and Kevin Wayne.
