If you'd like to see interesting solutions to this problem, I recommend solving this 4clojure exercise: http://www.4clojure.com/problem/104 http://www.4clojure.com/problem/104 and then looking at solutions by experienced Clojurians. Some are code golf but still worth understanding (e.g chouser's, who is one of the authors of The Joy of Clojure).
