Background & Objectives

When recruiting developers for your team, you often interview people who struggle with basic code. There is a famous article talking about Why Can't Programmers... Program? where it talks about the "FizzBuzz" problem.

Let's work on this basic program and make sure that we can do it 😊

Specs

Write a method fizz_buzz which takes a number as an argument, and return an array of number elements from 1 to number, but replaces some of them according to these rules:

• If the number is divisible by 3, then replace it by 'Fizz'
• If the number is divisible by 5, then replace it by 'Buzz'
• If the number is divisible by both 3 and 5, then replace it by 'FizzBuzz'

e.g.

fizz_buzz(7)
# => [1, 2, 'Fizz', 4, 'Buzz', 'Fizz', 7]
