Class SattoloShuffle<T extends java.lang.Comparable>

java.lang.Object

com.sl.algorithms.shuffle.SattoloShuffle<T>

All Implemented Interfaces:

BaseInterface<T>, Constants, ShufflingEngine<T>

public class SattoloShuffle<T extends java.lang.Comparable>
extends java.lang.Object
implements ShufflingEngine<T>

FisherYatesKnuthShuffle produces a random permutation while SattoloShuffle produces a random permutation with exactly one cycle. i.e. we do not allow an element to be swapped with itself, which implies an element will never end-up in it's original position.
