Hi..I've a little problem using recur for recursive calling...I'm
trying do the clojure koans and the recursive reverse function
[1 2 3 4] -> '(4 3 2 1)
first I try this code:
(defn recursive-reverse [coll]
(loop [col coll mem '()]
(if (empty? coll)
mem
((cons (last col) mem)
(recur (butlast col) mem) ))))
this didn't work and I thought the problem was (butlast col) and
rewrite the code to this
(defn recursive-reverse [coll]
(loop [col (butlast coll) mem (list (last coll))]
(if (empty? coll)
mem
((cons (last col) mem)
(recur col mem) ))))
why isn't a tail recur?...my recursion is de latest operation in the
functin
thanks so much
I hope learn a lot about functional programming
