Solving the classic 'Fizzbuzz' technical question

Fizzbuzz

Summary:

FizzBuzz is a classic programming exercise (and fairly common interview question).

The usual example asks the developer to write a program which prints out each number from 1 to 100. But for multiples of 3 print 'Fizz' instead of the number and for multiples of 5 print 'Buzz'. For numbers which are multiples of both 3 and 5 print 'FizzBuzz'.

This exercise has a little twist. Write a method called super_fizzbuzz which takes as its input an Array of integers.

It should return a "fizzbuzzed" Array, i.e., the array is identical to the input with the following substitutions:

1. Multiples of 3 should be replaced with the string "Fizz"
2. Multiples of 5 should be replaced with the string "Buzz"
3. Multiples of 15 should be replaced with the string "FizzBuzz"

For example:

super_fizzbuzz([1,2,3])  # => [1, 2, "Fizz"]
super_fizzbuzz([1,2,5])  # => [1, 2, "Buzz"]
super_fizzbuzz([1,2,15]) # => [1, 2, "FizzBuzz"]

super_fizzbuzz([30, 9, 20, 1]) # => ["FizzBuzz", "Fizz", "Buzz", 1]
