<div dir="ltr"><div dir="ltr">Hi Luciano,<br></div><div> thank you for the fix. It is integrated now and I added a couple of tests to SequenceableCollectionTest, one when k is cero and another for the normal case.</div><div><br></div><div> When I wrote the test for the normal case I notice that the collection passed as parameter to the block it is always the name and therefore the following test fails:</div><div>testCombinationsAtATimeDoWorksAsExpected<br> <br> | combinations |<br> <br> combinations := OrderedCollection new.<br> 'abc' combinations: 2 atATimeDo: [ :combination | combinations add: combination].<br> <br> self assert: 3 equals: combinations size.<br> self assert: (combinations includes: #($a $b)).<br> self assert: (combinations includes: #($a $c)).<br> self assert: (combinations includes: #($b $c)).<br></div><div><br></div><div>To make it pass I had to make a copy of combination. </div><div>...<br>'abc' combinations: 2 atATimeDo: [ :combination | combinations add: combination <b>copy</b>].<br>....</div><div><br></div><div>Is that the expected behavior? It looks weird to me... I would expect combination to be different collections on each iteration...</div><div><br></div><div>Cheers!</div><div>Hernan.</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, May 23, 2019 at 1:13 PM Luciano Notarfrancesco via Cuis-dev <<a href="mailto:cuis-dev@lists.cuis.st">cuis-dev@lists.cuis.st</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">The method was failing for the corner case of "combinations of 0 elements".
