Instance Method Details

#fizzbuzz(reverse = false, &block) ⇒ Object

call-seq:

array.fizzbuzz( reverse ) {|value| block } -> self
array.fizzbuzz( reverse )                  -> array

Returns either an array or accepts a block if such is given. When a block is given then it will call the block once for each subsequent value for a given array, passing the value as a parameter to the block.

Additionally, if the value of reverse is set to be true then the results will be given in an reverse order whether in a resulting array or when passing values to a block given.

Example:

array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]
array.fizzbuzz          #=> [1, 2, "Fizz", 4, "Buzz", "Fizz", 7, 8, "Fizz", "Buzz", 11, "Fizz", 13, 14, "FizzBuzz"]
array.fizzbuzz(true)    #=> ["FizzBuzz", 14, 13, "Fizz", 11, "Buzz", "Fizz", 8, 7, "Fizz", "Buzz", 4, "Fizz", 2, 1]

Example:

array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]
array.fizzbuzz {|value| puts "Got #{value}" }

Produces:

Got 1
Got 2
Got Fizz
Got 4
Got Buzz
Got Fizz
Got 7
Got 8
Got Fizz
Got Buzz
Got 11
Got Fizz
Got 13
Got 14
Got FizzBuzz
