99 Clojure Problems – 13: Run-length Encoding of a List (Direct Solution)

Implement the so-called run-length encoding data compression method directly. I.e. don't use other methods you've written (like P09's pack); do all the work directly.


(deftest p13-decode
  (is (= '( a a a a b c c a a d e e e e) (decode '((4 a) (1 b) (2 c) (2 a) (1 d) (4 e))) )))


Maybe I missed the point here, but my solution is identical to the solution of problem 10 after the substitution of pack with its body.
