Unmix Screencast

December 30, 2019

tl;dr A simpler problem begets a shorter screencast.

It’s a different coding problem from the same newsletter as the last one. It was a simpler problem, and thus went much, much faster. (It’s still not very good, mind you, but it’s a learning process.)

And here’s the code:

src/pf/unmix.clj

(ns pf.unmix)

(defn unmix [s]
  (->> s
       (partition-all 2)
       (map reverse)
       (apply concat)
       (apply str)))

(comment
  (unmix "aHpp yeN weYra !eS eoy uni2 20 0):"))

test/pf/unmix_test.clj

(ns pf.unmix-test
  (:require [clojure.test :refer :all]
            [pf.unmix :refer [unmix]]))

(deftest unmix-test
  (are [x y] (= x (unmix y))
             "Hello" "eHllo"
             "Clojure" "lCjorue"))
