Fairly decent and above-average-industry-difficulty coding exercise which was fun to code, however when your solution doesn't pass, you will just hear "it's not passing our functional tests". So a reply rather than a feedback. Despite your solution correctly compiles, might have clean code, 15+ tests written (with correctly asserted numbers against original description) - you won't hear what was wrong...
