Hello, All in all, you only used in your first definition "core" clojure constructs, you avoided doing "imperative in clojure clothes". So, while not leveraging to its full extent the power of clojure standard library functions and higher-order-functions, your code certainly qualifies as functional and in the spirit of clojure.
