--------------------------------------
Surround the System.out.print with these comments:
{noformat}
// CHECKSTYLE: stop regex
// ...
// code with System.(out|err)
// ...
// CHECKSTYLE: resume regex

> Key: NUMBERS-215
> URL: https://issues.apache.org/jira/browse/NUMBERS-215
> Project: Commons Numbers
> Issue Type: New Feature
> Components: combinatorics
> Reporter: Gilles Sadowski
> Assignee: Gilles Sadowski
> Priority: Minor
> Fix For: 1.4
>
>
> Would it be useful to provide functionality to *iterate* over the partitions
> defined by "Stirling number of the second kind" (i.e. all partitions into K
> subsets, of a set of N elements)?
> Code would be in a nested static class of the existing
> [{{Stirling}}|https://commons.apache.org/proper/commons-numbers/commons-numbers-combinatorics/apidocs/src-html/org/apache/commons/numbers/combinatorics/Stirling.html]
> class:
> {code}
> public final class Stirling {
> // ...
> public static final class S2 implements Iterable<List<List<Integer>> {
> // ...
> public static S2 of(int n, int k) {
> // ...
> }
> }
> }
> {code}
> I have a potential use case (for very small "N").
