greed.rb

# My approach for the greed game was to take the values in a roll and sort them into seperate arrays. For example all the ones would be in an array, twos in an array, etc.. To keep these neat and tidy I will organize them into a hash.
# I could create a class called dice with two methods, roll and score: 
#The roll method will randomly generate the numbers for the roll (I don't think this project included that but I'll add it anyways) and them store them into their arrays of similar numbers.
# The score method would be responsible for taking the sorted arrays and calculating the score then return the score.

class Dice

	def initialize
		@roll = {1 => [], 2 => [], 3 => [], 4 => [], 5 => [], 6 => []}
		@points = 0
	end

	def roll(count)
		dice = []

		# Generate Values
	    dice = (1..count).map { |_| Random.rand(1..6) }

		dice.each do |die|
			@roll[die] << die
		end

		# Output roll to user
		puts dice.join(", ")
	end

	def score
		# Split the hash
		remain = @roll.reject{ |k| k == 1 || k == 5 }
		special = @roll.reject{ |k| k == 2 || k == 3 || k == 4 || k == 6 }

		# Handle the specials
		special.each do |key, array|
			if key == 1
				calculate_specials(key, array, 1000, 100)
			elsif key == 5
				calculate_specials(key, array, 500, 50)
			end
				
		end

		# Handle the remaining
		remain.each do |key, array|
			@points = @points + (100 * key) if array.length >= 3
		end

		puts "#{@points}"
	end

	def calculate_specials(value, nums = [], high_score, low_score)
		if nums.length >= 4
			@points = @points + high_score
			leftovers = nums.length - 3
			@points = @points + (low_score * leftovers)
		elsif nums.length == 3
			@points = @points + high_score
		else
			@points = @points + (low_score * nums.length)
