Hello everybody,
I just needed a function for every-nth element in a sequence.. I know it
can be trivially implemented as ..
(defn every-nth [n coll]
(letfn [(evn [cn s]
(when s
(if (= cn 1)
(lazy-seq (cons (first s) (evn n (next s))))
(evn (dec cn) (next s)))))]
(evn n coll)))
But I remember seeing inbuilt function .. can anybody help me find it?
Sunil.
