Selection (Algorithms 4/e)

Object
- edu.princeton.cs.algs4.Selection

```
public class Selection
extends Object
```
The Selection class provides static methods for sorting an array using selection sort. This implementation makes ~ ½ n² 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.

Method Summary

All Methods Static Methods Concrete Methods
Modifier and Type	Method	Description
`static void`	`main(String[] args)`	Reads in a sequence of strings from standard input; selection sorts them; and prints them to standard output in ascending order.
`static void`	`sort(Comparable[] a)`	Rearranges the array in ascending order, using the natural order.
`static void`	`sort(Object[] a, Comparator comparator)`	Rearranges the array in ascending order, using a comparator.
