Implement a basic Die class which can be initialized with some number of sides. We can then roll the die, returning a random number. It should work like this: die = Die.new(6) die.sides # returns 6 die.roll # returns a random number between 1 and 6 If we pass Die.new a number less than 1, we should raise an ArgumentError. This is done using the …

Working off your previous Die class from Die Class 1, implement a new Die class which takes an array of strings as its input. When Die#roll is called, it randomly returns one of these strings. If Die.new is passed an empty array, raise an ArgumentError. It should work like this: `die = Die.new(['A', 'B', 'C', 'D', 'E', 'F’])` `die.sides # still …

Exercise: Build a simple guessing gameCreate 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 …

	# INPUT: initialize a game passing the correct integer answer to instantiate;

	# if the most recent guess is too high, too low, or correct
	# #solved? outputs true if the most recent guess is correct and flase otherwise.
	# STEPS: #initialize -> set answer to instance variable, answer
	#guess -> return corresponding symbol for too high, too low, correct

Exercise: Class Warfare, Validate a Credit Card NumberGiven a credit card number we should be able to validate whether it is valid based on the Luhn algorithm. While the word algorithm sounds scary you can just think of them as a series of steps you use to solve a specific problem. An example algorithm:Heat water until boilingAdd pastaIf pasta c…
