Щоб отримати додаткові бали

Чи вдалося пройти тести й написати чистий код? Якщо є бажання, ось кілька додаткових речей, які можна спробувати:

  • Прибрати якомога більше дублювання.
  • Оптимізувати код заради читабельності, навіть якщо це означає додати дублювання.
  • Якщо ми прибрали все дублювання, чи не залишилося багато умовних конструкцій? Спробуймо замінити їх поліморфізмом, якщо це доречно в цій мові. Наскільки читабельним вийшов код?

А потім поділіться своїми думками в коментарі до рішення. Чи став код від цього експерименту кращим? Гіршим? Чи дізналися ми щось із цього?
