Problem Description

Simple, given a string of words, return the length of the shortest word(s).

String will never be empty and you do not need to account for different data types.

Note

• clojure.string/split -> It splits a string into substrings, based on a regular expression (regex).

  • #"" -> In Clojure, #"" defines a regular expression literal.
  • \s -> any whitespace character (space, tab, newline, etc.)
  • + -> “one or more” of the previous element.

Implementation

; implement
(defn find_shortest [words]
  (->> (clojure.string/split words #"\s+")
       (map count)
       sort
       first))

; test
; execute implement function
(defn tester [arg exp]
  (= (find_shortest arg) exp))

; args & exception
