I wonder whether the utility should involve the creation of
an instance of a bona fide "Combination" class.
I.e. instead of a "naked"
Iterator<int[]> combinationIterator(int n, int k)
there would be
Iterator<Combination> combinationIterator(int n, int k)
where "Combination" would provide an accessor
public int[] toArray() {
// ...
}
The advantage is that "Combination" could also implement
Comparable<Combination>
with code similar to the "lexNorm" method defined for the tests.
Or did I miss something?
