My answer

python

num = gets.to_i
(1..num).each do |n|
    if n % 15 == 0
        puts "Fizz Buzz"
    elsif n % 5 == 0
        puts "Buzz"
    elsif n % 3 == 0
        puts "Fizz"
    else
        puts n
    end
end

The point is that (1..num) takes out the numbers from 1 to num in order with the each method, and when divided by 3, 5, and 15, if it becomes 0, the character string is output. It's very simple, but it can be a tough problem if you don't have a programming brain. Don't forget else!

that's all!
