Teacher's solution for Sudoku_solver

	=begin
	#PSEUDOCODE FOR PHASE 2
	solve!

	#STEP 1...next step is either step 2 or 3

kmandreza / The Power of Enumerable

Created January 30, 2013 00:47

When you need to operate on a Ruby Array, you can accomplish just about anything you can imagine with the each method. Often, though, using each is not the best way to work with Arrays. For example, when you find yourself adding conditional logic inside your each block, or using each to search, sort, or transform the Array, consider the power of…

	# Print the 1st, 3rd, 5th, 7th, etc. elements of a list on separate lines.
	def print_odd_indexed_integers(array)
	array.each_with_index do \|item, index\|
	if index.even?
	#should be .odd? in the spec
	puts item
	end
	end
	end

kmandreza / Build a simple guessing game

Created January 20, 2013 18:35

Create a GuessingGame class which is initialized with an integer called answer. Define an instance method GuessingGame#guess which takes an integer called guess as its input. guess should return the symbol :high if the guess is larger than the answer, :correct if the guess is equal to the answer, and :low if the guess is lower than the answer. D…

	class GuessingGame
	def initialize(answer)
	@answer = answer
	end

	def guess(guess)
	@guess = guess
	if guess > @answer
	return :high
	elsif guess == @answer

kmandreza / Pseudocode

Created January 12, 2013 04:28

Using pseudocode, write a simple hangman game. The point of pseudocode is to represent the logical structureof a program without getting bogged down in the syntax of a particular language. For example, a program to select the largest integer from an array of integers might be written like this in pseudocode initialize max_so_far to the first ele…

	# generate a word at random and store it in a variable
	# display the length of the word to the user
	# correct_guesses is less than the length of the word
	# prompt the user to guess a letter
	# if the guess is correct increment correct_guesses by 1
	# if the guess is incorrect increment incorrect_guesses by 1
	# and draw the next part of the hangman
	# if the incorrect_guesses is greater than 8, tell the user
	# they lost and exit the program
	# if correct_guesses is equal to the length of the word, tell the user they won

kmandreza / Refactor a method

Refactor a method

	def method_4(array)
	results = []

	array.each do \|num\|
	if num % 2 == 0
	results << num
	end
	end

	return results

kmandreza / fizzblam

Created January 12, 2013 04:24

Write a method called fizzblam that prints the numbers from 1 to 1000. But for multiples of 5 print “Fizz” instead of the number and for the multiples of 7 print “Blam”. For numbers which are multiples of both 5 and 7 print “FizzBlam.”

	def fizzblam
	1000.times do \|n\|
	if (n+1) %7 == 0 && (n+1) %5 == 0
	puts "FizzBlam"
	elsif (n+1) %5 == 0
	puts "Fizz"
	elsif (n+1) %7 == 0
	puts "Blam"
	else
	puts n + 1

kmandreza / returns the product of all the odd integers in an array

Created January 12, 2013 04:21

Write a method called product_odd which takes as its input an array of integers and returns the product of all the odd integers in the array. Remember that technically 0 is an even integer. For example: product_odd([1,2,3]) # returns 3, because 2 is even product_odd([0,-1,-10]) # returns -1, because 0 and -10 are even product_odd([1,2,3,4,5]) # …

	def product_odd(x)
	odd = x.select {\|y\| y%2 == 1}
	p = 1
	odd.each do \|y\|
	p = p * y
	end
	p
	end

kmandreza / return the product of an array of integers

Created January 12, 2013 04:20

Write a method called product which takes as its input an array of integers and returns their product. For example product([1,2,3]) # returns 6 product([0,-1,-10]) # returns 0 product([1,-1,-10]) # returns -11 If you need to iterate over the array, please use Array#each. Don’t use, e.g., inject.

	def product(x)
	p = 1
	x.each do \|y\|
	p = p * y
	end

	p
	end

kmandreza / concatenate strings

Created January 12, 2013 04:19

Create a method new_cat which takes as its input two strings. It should concatenate the strings and return the concatenated value, without modifying either of the input strings. For example, # One does not simply walk into... new_cat("Mor", "dor") # => "Mordor" Call this method and send your first and last name as arguments.

	def new_cat(str1, str2)
	str1 + str2
	end

	puts new_cat("Mor","dor")
