Looking at my twitter feed I saw the following Quora question: How do I write a program that produces the following output?.
People were all trying to create some cyphered program that would produce the desired output, the perl one was funny.
At the time I didn’t found a Clojure take on this hard problem.
Code!
So, here’s a Clojure one with magic randomness immutability.
(defn foo [a b]
"Do some char foo."
(char (+ a b)))
(defn bar [a]
"Keep only some foo from foos."
(take-while #(not= % 0) a))
(defn bazz [a b]
"Transform some foo."
(map #(foo (second a) %) b))
(defn bar-bazz [a]
"Iterate on some random foo."
(let [r (new Random (first a))]
(apply str (bazz a (bar (repeatedly #(.nextInt r 27)))))))
(defn foo-bar [a z]
"Construct some magic foo from a lot of foo."
(let [r (range z 0 -1)]
(map #(conj ["\n"] (take % (repeatedly (fn [] (apply str (map bar-bazz a)))))) r)))
(defn please-do-my-homework [number-of-times]
"This is your homework :)"
(let [magic [[-9223372036854775771 66] [-9223372036854209285 95] [-9223372036854775771 16]]]
(print (apply str (flatten (foo-bar magic number-of-times))))))Execution
