Line 4:
It prints out the factors seperated by * to stdout, In the context of unix, where everything is a text stream this counts as a collection.
Why do you think it's unconventional, If you haven't used libgmp it may look strange.

This method seems to be incorrect. E.g. it does not find the decomposition for 2^41 - 1 == 13367 * 164511353. Can someone confirm this?

I also think that bignum/growing array requirements should be dropped. At the very least, the title of the page should indicate that big numbers are part of the challenge. --[[User:Showell|Showell]] 07:33, 5 January 2012 (UTC)
:Agreed. The task is asking far too much. Integer factorization is one of those basic programs one learns early, in any language. But if bignums are required, it's entirely another matter: first one needs a library (relatively hard), then one needs a good factorization algorithm (very hard).
