get partial sequence clojure from a longer sequence

Question

Given a sequence ("a","b","c","d","e"), what is the best way to get a subsequence of it, like ("c","d","e")?

I looked up subseq but it requires a test which in this case I want to be able to just supply the position.

Answer 1

The easiest way is to use drop & take:

(def data  ["a","b","c","d","e"] )
(take 3 (drop 2 data))

If the data is a vector (square brackets, notice change above), you can use subvec:

(subvec data 2 5)

To ensure it is a vector, it is easy to use vec

(subvec (vec data) 2 5)

=> ["c" "d" "e"]
