Drunk Proxy

Дефинирайте клас DrunkProxy, чийто конструктор приема като единствен аргумент списък от обекти. Инстанцията на класа трябва да отговаря на всички методи, на които отговарят подадените обекти в конструктора. Възможно е няколко обекта да могат да отговорят на един метод (например '123'.length и [1, 2].length). Ако проксито може да отговори на даден метод, то връща списък с резултатите от всички обекти, които са кандидати за отговор (редът в списъка на резултатите трябва да съответства на реда на подаване на обектите при инициализация).

Примери:

proxy = DrunkProxy.new [-42, 'foo', 'bar baz', [2, 3, 5, 8]]
proxy.reverse # => ["oof", "zab rab", [8, 5, 3, 2]]
proxy.abs     # => [42]
proxy.length  # => [3, 7, 4]
# ----------------------------------------------------------
proxy = DrunkProxy.new ['foo', [24], {x: 2}]
proxy.class   # => [String, Array, Hash]

Бележки:

  • Ако няма обект, който да отговори на дадения метод, вдигнете NoMethodError изключение.
  • Постарайте се да прихванете всички методи, на които подадените обекти могат да отговорят. Изключение правят !, ==, !=, __send__, equal?, instance_veal, instance_exec, __id__ и __binding__
  • Няма да подаваме блокове на методите в тестовете. Тоест, не се тревожете за нещо подобно на:
proxy = DrunkProxy.new [[2, 3, 5, 8], {a: 1, b: 2, c: 3}]
proxy.select(&:odd?)
proxy.select { |x| x > 42 }
