A memorandum of the FizzBuzz problem

The FizzBuzz problem that appeared in yesterday's drill.

As a model answer,

def fizz_buzz
  num = 1
  while num <= 100 do
    if num % 15 == 0
      puts "FizzBuzz"
    elsif num % 3 == 0
      puts "Fizz"
    elsif num % 5 == 0
      puts "Buzz"
    else
      puts num
    end

    num = num + 1
  end
end

fizz_buzz

That was the correct answer, When I used rubocop,

def fizz_buzz
  num = 1
  while num <= 100
    if (num % 15).zero?
      puts 'FizzBuzz'
    elsif (num % 3).zero?
      puts 'Fizz'
    elsif (num % 5).zero?
      puts 'Buzz'
    else
      puts num
    end
    num += 1
  end
end

fizz_buzz

In the form of Enclose the formula in () and judge "whether or not the value is 0", Another description (accidentally) using the zero? method was made.

As for rubocop, I think it would be nice to have a clean and tidy description as much as possible.
