I didn't spend any time golfing this quiz, so I don't have anything crazy to
share.  I tried to implement it as I would in an interview - so my intent
was clear.

My first attempt was procedural.  The only thing that may be tricky is that
I don't t have any logic specific for printing "FizzBuzz", I build that
value when the number is divisible by both 3 and 5.

(1..100).each do |i|
   result = ''
   result += 'Fizz' if i % 3 == 0
   result += 'Buzz' if i % 5 == 0
   result = i if result.empty?
   puts result
end

That is how I would solve it if I was at a whiteboard.  Afterwards I would
explain how I would refactor this out to make it reusable, and I would end
up with this:

class Integer
   def fizz_buzz
     result = ''
     result += 'Fizz' if self % 3 == 0
     result += 'Buzz' if self % 5 == 0
     result = self if result.empty?
     result
   end
end

(1..100).each { |i| puts i.fizz_buzz } if __FILE__ == $0
