This should call a new instance of the class - but the first line isn't liked

	val wager = "Great! How much do you want to wager?"
	val leave = "Well, thanks for coming out today, partner."
	val again = "I didn't quite catch that, sonny. You'll have to speak up."
	val get = readLine()

	class wagers
	println(wager)
	class leaves
	println(leave)
	class agains

There must be an easier, non-compiler-breaking way

	def wager(bet: Int, heads: Int, total: Int, flip: Int): (Boolean, Int, Int) = {

	if(total > 1000) = heads match {

	case 0 => (false, 1, total-bet)

	case 1 => (false, 0, total-bet)

	} else {

You can't have an if inside a case


	object WagerGameAction extends GameAction {
	def execute(gameState: GameState): GameState = gameState match {
	case Wager(stake) => {
	println(wagers)
	print(increments25)
	print(increments25ForYou)
	val betVal = readLine()
	val realBet = confirm(scala.math.abs(betVal.toInt))
	if (!afford(realBet, stake)) {

It's an api, you fool. Don't make the whole game!

	TTT API requirements
	object tttmeanderings {



	//make a move (which takes a board state gives me back the updated board state)

	//

	//ask who won (which only takes a board state that represents a finished game and tells me that X's won, O's won, or it was a draw)

DeepSky8 / problem26.scala

Generate the combinations of K distinct objects chosen from the N elements of a list. In how many ways can a committee of 3 be chosen from a group of 12 people? We all know that there are C(12,3) = 220 possibilities (C(N,K) denotes the well-known binomial coefficient). For pure mathematicians, this result may be great. But we want to really gene…

	scala> combinations(3, List('a, 'b, 'c, 'd, 'e, 'f, 'g, h', i', j', k', l'))
	res0: List[List[Symbol]] = List(List('a, 'b, 'c), List('a, 'b, 'd), List('a, 'b, 'e), ...

	def combinations[A](size: Int, pool: List[A]): List[List[A]] = pool match {
	case Nil => Nil
	case h :: t => if(size <= 0) Nil else if (size == 1) {
	list(h) :: combinations(size, t)
	} else {
	helper(h, combinations(size-1, t)
