help for problem 33, replicate a sequence

I can make the first 3 unit tests pass but not the last two (because
of flatten). Any and all help is much appreciated.

Are you sure it's 31 you're talking about (Pack a Sequence)?

It only has 3 unit tests on it, not 5.

If it's 31 you're talking about I solved it with partition-by identity, which will group things based on whether they're the same thing:

#(partition-by identity %)

Oops, sorry about that. It's 33 as it says in the subject. URL:

Oops, missed your title, just looked at the url.

Ok, I solved that one with mapcat & repeat:

(fn [s n] (mapcat #(repeat n %) s))

mapcat (http://clojuredocs.org/clojure_core/clojure.core/mapcat) is helpful for quite a few of the "Easy" level problems that I've figured out so far.
