Greetings all!
I'm just starting out in the so far wonderful world of Clojure and to help
me get started I had a crack at one of my favourites, the FizzBuzz program.
For anyone that isn't familiar with FizzBuzz, it is designed to count from
1 to N and take the following actions when certain conditions are met:
- When the remainder of i divided by 3 is 0 print "Fizz"
- When the remainder of i divided by 5 is 0 print "Buzz"
- When both the former are true of i print "FizzBuzz"
I crafted the following as a solution and I would really appreciate some
more experienced Clojurians casting their eye over it and letting me know
if what I've done is in the style and spirit of Clojure. Also this is my
first functional language so any feedback on that would be awesome too. :)
I'm aware it's only a teeeeeeeensy piece of code so not terribly indicative
of the hilarity that might ensue on a larger project but all the same.
Enough of my blathering here is the meaty bit:
(defn zero-remainder? [x y]
(zero? (rem x y)))
(defn fizzy [x]
(let [fizz (zero-remainder? x 3) buzz (zero-remainder? x 5)]
(if (and fizz buzz)
(println "FizzBuzz: " x)
(if buzz
(println "Buzz: " x)
(if fizz
(println "Fizz: " x))))))
(doseq [x (range 1 25)]
(fizzy x))
