FizzBuzz First Time.

July 3, 2016

source: github

This is my first time working on FizzBuzz. I’ve heard of it from other for some time, didn’t pay much attention to it. But an acquaintance asked me recently how would I do if I were to be interviewed and asked to do it. So, this’s it.

Just like when working on any other interview processes, the code should have quality to ship immediately if needed. I also write along some unit tests in case I might want to try refactor it after this. Though I’m already feel that this is already good enough for me.

fizzbuzz.rb
module FizzBuzz
class << self
def out(range: 1..100)
range.map { |num| fizzbuzz(num) }
end
private
def fizzbuzz(i)
if fizzbuzz?(i)
'fizzbuzz'
elsif fizz?(i)
'fizz'
elsif buzz?(i)
'buzz'
else
i
end
end
def fizzbuzz?(i)
fizz?(i) && buzz?(i)
end
def fizz?(i)
i % 3 == 0
end
def buzz?(i)
i % 5 == 0
end
end
end
# puts FizzBuzz.out.to_s # printing results
