kmazanec / modern_roman.rb

Last active December 19, 2015 20:19

Modern Roman Numeral generator - am I missing a way to make this simpler? I know I could use a case statement and tighten things up that way, but logically, am I missing something?

	def roman input
	if input < 0 \|\| input >= 10000
	'Out of bounds'
	elsif input >= 1000 && input < 10000
	'M' * (input / 1000) + roman(input % 1000)
	elsif input >=900 && input < 1000
	'CM' + roman(input-900)
	elsif input >= 500 && input < 900
	'D' + roman(input-500)
	elsif input >= 400 && input < 500

kmazanec / flatten.rb

Created July 17, 2013 12:52

Flatten an array using a mix of iteration and recursion

	def flatten(array)
	return nil unless array.is_a?(Array)
	array.each do \|item\|
	if item.is_a?(Array)
	flatten(item).reverse_each do \|inner_item\|
	#add to array at index of item
	array.insert(array.index(item)+1, inner_item)
	end
	#remove pre-existing array
	array.delete(item)

kmazanec / flatten_recursive.rb

Last active December 19, 2015 21:29

Flatten an array entirely using recursion. (I am particularly amazed at how short and simple this is compared to using iteration)

	def flatten(array)
	return Array(array) unless array.is_a?(Array) && array.length > 0
	flatten(array.shift) + flatten(array)
	end


	array = ["bananas", [1,2,3], ["apple", "cheese", [100, 20]], [true], [4.0, 7, 32]]
	puts flatten(array).to_s

	array = ["bananas"]

kmazanec / sum.rb

Created August 16, 2013 19:51

Recursively sum an indefinite number of elements. Use the splat operator to take any number of arguments. When calling this method, be sure to use the splat operator on any arrays that are passed to it or it will not function properly.

	def sum ( *args )
	args.length > 1 ? args.pop + sum(*args) : args.pop
	end


	test_array = [1,2,3,4]

	puts sum(1,2) # ==> 3

	puts sum(*test_array) # ==> 10

kmazanec / PokerHand.rb

Last active December 21, 2015 07:58

	class PokerHand
	attr_reader :hand, :score
	def initialize (hand)
	@hand = hand
	@straight = @flush = @full_house = @quad = @triple = @two_pair = @pair = false
	@score = 0
	end

	def evaluate
	hands = @hand.scan(/[cdsh]/) # Creates array for suits

kmazanec / poker.rb

Created August 19, 2013 22:14

Created some wrapper code to utilize the PokerHand class. Fully interactive from the command line! (and yes, it's a bit of a mess)

	# Poker

	require_relative "PokerHand.rb"

	class Deck
	@@CLASSIC_DECK = ['2d','3d','4d','5d','6d','7d','8d','9d','Td','Jd','Qd','Kd','Ad'] +
	['2h','3h','4h','5h','6h','7h','8h','9h','Th','Jh','Qh','Kh','Ah'] +
	['2s','3s','4s','5s','6s','7s','8s','9s','Ts','Js','Qs','Ks','As'] +
	['2c','3c','4c','5c','6c','7c','8c','9c','Tc','Jc','Qc','Kc','Ac']

kmazanec / methods_and_recursion.rb

Last active December 22, 2015 04:28

Portfolio 1: Methods and Recursion


	# Create a dictionary of english words mapped to number values
	# Take in a number
	# Start with the largest value in the dictionary, see if the number is evenly divisible by it
	# IF it is, then add that word to the method called on the number with the value of the word divided out
	# Return the string

kmazanec / .bash_profile

Created September 15, 2013 00:41

My current .bash_profile. The "today" function will make getting to the right folder much easier. Simply type "today" on the command line.


	function parse_git_branch () {
	git branch 2> /dev/null \| sed -e '/^[^]/d' -e 's/ $.*$/ (\1)/'
	}

	function today () {
	today=$(date +"%m%d")

	# Modify the line below to your local dropbox path from ~
	# Ex: /Users/Keith/Dropbox/Fireflies/Keith
