abrahamsangha / P5: OO Inheritance.rb

Last active December 19, 2015 07:28 — forked from dbc-challenges/P5: OO Inheritance.rb

	class Vehicle
	def initialize(args)
	@color = args[:color]
	@wheels = args[:wheels]
	@gas_mileage = [true,false]
	end
	def drive
	@status = :driving
	end
	def brake

abrahamsangha / array_mode.rb

Created June 7, 2013 20:03

Write a method mode which takes an Array of numbers as its input and returns an Array of the most frequent values. If there's only one most-frequent value, it returns a single-element Array.

	def mode(array)
	hash = Hash.new(0)
	array.each { \|elem\| hash[elem] += 1 }
	hash.keep_if { \|k, v\| v == hash.values.max }.keys
	end

abrahamsangha / method_missing.rb

Last active December 18, 2015 03:19

The instructions were to fix this bad code with a method_missing method.

	class Person
	def initialize(name, age, incoming_race)
	@name = name
	@age = age
	self.race = incoming_race
	end

	def nam
	@name.split.map(&:capitalize).join(" ")
	end

abrahamsangha / fizzblam.rb

Last active December 18, 2015 02:09

The challenge was to create a method that returned an array of numbers from 1 to 1000 but with each number that included 5 as a factor replaced with "Fizz", each number that included 7 as a factor replaced with "Blam" and each number that included both 5 and 7 as factors replaced with "FizzBlam". The additional challenge was to do it in one line…

	def fizzblam
	arr = (1..1000).to_a.map { \|elem\| [("Fizz" if (elem % 5).zero?), ("Buzz" if (elem % 7).zero?), (elem unless ((elem % 5).zero?) \|\| ((elem % 7).zero?))].compact.join }
	end

	#another way to do it using string interpolation

	def fizzblam
	arr = (1..1000).to_a.map { \|elem\| "#{'Fizz' if elem % 3 == 0}#{'Buzz' if elem % 5 == 0}#{elem unless elem % 3 == 0 \|\| elem % 5 == 0}"
	end

abrahamsangha / grocery_list.rb

Created June 3, 2013 20:22

	def addition item
	@list[item] ? @list[item] += 1 : @list[item] = 1
	@list
	end

abrahamsangha / reverse_words

Created May 9, 2013 12:51

a method reverse_words which takes a sentence as a string and reverse each word in it.

	def reverse_words(str)
	str.split.each { \|word\| word.reverse!}.join(' ')
	end

abrahamsangha / separate_comma

Created May 9, 2013 12:39

method separate_comma which takes an integer as its input and returns a comma-separated integer as a string

	def separate_comma(number)
	number.to_s.reverse.gsub(/(\d{3})(?=\d)(?!\d*\.)/, '\1,').reverse
	end

abrahamsangha / regexpssn

Created May 9, 2013 11:50

Using Regexp to find Social Security Numbers

	# Determine whether a string contains a Social Security number.
	def has_ssn?(string)
	string.match(/\d{3}\-\d\d\-\d{4}/)
	end

	# Return the Social Security number from a string.
	def grab_ssn(string)
	string[/\d{3}\-\d\d\-\d{4}/]
	end

abrahamsangha / Die

Created May 9, 2013 11:46

Implement a basic Die class which can be initialized with some number of sides. We can then roll the die, returning a random number.

	class Die
	def initialize(sides)
	raise ArgumentError.new("Need at least one side") unless sides >= 1
	@sides = sides
	end

	def sides
	@sides
	end
