oke, I misunderstood everyone. The right answer is last.
(def A (__ (sort (rest (reverse [2 5 4 1 3 6]))))) which would be : (def A (last (sort (rest (reverse [2 5 4 1 3 6]))))) which resolves to 5 (def B (-> [2 5 4 1 3 6] (reverse) (rest) (sort) (__))) Which would be : (def B (-> [2 5 4 1 3 6] (reverse) (rest) (sort) (last))) which resolves also to 5 so the last part : ( = a b 5) is also true ( = 5 5 5) Still I find it wierd to make such sort of form.
