Iterates over combinations.
Iterates over combinations. A _combination_ of length
n
is a subsequence of the original sequence, with the elements taken in order. Thus,"xy"
and"yy"
are both length-2 combinations of"xyy"

is not. If there is more than one way to generate the same subsequence, only one will be returned.For example,
"xyyy"
has three different ways to generate"xy"
depending on whether the first, second, or third"y"
is selected. However, since all are identical, only one will be chosen. Which of the three will be taken is an implementation detail that is not defined.- returns
An Iterator which traverses the possible n-element combinations of this sequence.

- returns

Builder
will break laziness. As a consequence, operations should preferably be implemented on top of views rather than builders.
