cc.redberry.core.combinatorics.IntCombinationsGenerator

This class represents an iterator over all unordered combinations (i.e. [0,1] and [1,0] are considered as same) of {@code k} numbers, which can be chosen from the set of{@code n} numbers, numbered in the order 0,1,2,...,{@code n}. The total number of such combinations is a binomial coefficient {@code n!/(k!(n-k)!)}.

The iterator is implemented such that each next combination will be calculated only on the invocation of method {@link #next()}.

Note: method {@link #next()} returns the same reference on each invocation.So, if it is needed not only to obtain the information from {@link #next()}, but also save the result, it is necessary to clone the returned array.
