Missing exercise solutions

[dmitrymar]

It would be great to have exercise solutions. In my case I wanted to verify if my solution to the exercise on page 189 (chapter 6) is correct.
Here is my attempt...

class Array
  def my_each
    c = 0
    until c == size
      yield self[c]
      c += 1
    end
    self
  end
end

class Integer
  def my_times
    c = 0
    acc = []
    until c == self
      acc << c
      c += 1
    end
    acc.my_each { |e| yield e }
    self
  end
end

5.my_times { |i| puts "I'm on iteration #{i}!" }

You should maybe give it a god and PR your solution. It works satisfyingly.
