SuperFizzBuzz

In this assignment you'll implement an algorithm that is actually used in some programmer interviews. And the really shocking part is that some people fail it! This is an extension of the FizzBuzz problem, SuperFizzBuzz.

A number has a corresponding output. The rules for determining the output are as follows:

• If it's evenly divisible by 3, 5, and 7 the output is SuperFizzBuzz
• If it's evenly divisible by 3 and 7 the output is SuperFizz
• If it's evenly divisible by 5 and 7 the output is SuperBuzz
• If it's evenly divisible by 3 and 5 the output is FizzBuzz
• If it's evenly divisible by 3, the output is Fizz
• If it's evenly divisible by 5, the output is Buzz
• If it's evenly divisible by 7, the output is Super
• Otherwise the output is just the number

Iteration 1

Write a program called super_fizz_buzz.rb. This program should iterate through the numbers 1 to 1000 and for each one, print the output according to the rules above. The output of your program should look something like this:

1
2
Fizz
4
Buzz
Fizz
Super
8
Fizz
Buzz
11
Fizz
13
Super
FizzBuzz
16
...

Iteration 2

Refactor your super_fizz_buzz.rb file into a class. You should be able to interact with your class from a pry session like so:

require './super_fizz_buzz'

super_fizz = SuperFizzBuzz.new

super_fizz.output(8)
# => "8"

super_fizz.output(15)
# => "FizzBuzz"

super_fizz.output_range(8, 15)
# => ["8", "Fizz", "Buzz", "11", "Fizz", "13", "Super", "FizzBuzz"]

Iteration 3

Write RSpec tests to verify the behavior of your class. Each method should have at least one test.

Iteration 4

Create a command line interface where the user can enter a number or a range of numbers and see the output. Example:

Welcome to SuperFizzBuzz! Enter a number or a range...

# => 15
SuperFizzBuzz

#=> 8, 15
8, Fizz, Buzz, 11, Fizz, 13, Super, FizzBuzz
