Class BigIntegerCombinations

java.lang.Object

org.beryx.streamplify.BigIntegerIndexedSpliterator<int[],BigIntegerCombinations>

org.beryx.streamplify.combination.BigIntegerCombinations

All Implemented Interfaces:

java.util.Spliterator<int[]>, Streamable<int[],BigIntegerCombinations>

public class BigIntegerCombinations
extends BigIntegerIndexedSpliterator<int[],BigIntegerCombinations>

Provides streams of combinations.
When the binomial coefficient (n choose k) can fit in a long, you may consider using the more efficient LongCombinations.
