Hi all,
Next problem. If I've a collection of sets of letters, and I want all
possible words you can make with this collection if you keep the order
of the sets intact, I would use 'for'. However, for wants me to know
beforehand how many sets there are in my collection. Is there a more
flexible way?
(for [x #{\a \b \c} y #{d} z #{e f}] [x y z]) works perfectly,
returning something I can turn into a set of #{ade adf bde bdf cde
cdf}. I'm looking for some function that I can just pass a collection
with any number of sets in it, and it starts spitting out the combined
strings. I looked briefly at permutations.clj and seq_utils.clj, but
didn't see an obvious/elegant way to do it in there, and the only way
I'd write it now in clojure is going to be ugly.
Anyone has a suggestion?
