I've assumed that if a player runs out of cards during a 'war', then the other player automatically wins the game.
<lang ecmascript>import "random" for Random
import "/queue" for Deque
var rand = Random.new()
var suits = ["♣", "♦", "♥", "♠"]
var faces = ["2", "3", "4", "5", "6", "7", "8", "9", "T", "J", "Q", "K", "A" ]
var cards = List.filled(52, null)
for (i in 0..51) cards[i] = "%(faces[i%13])%(suits[(i/13).floor])"
var ranks = List.filled(52, 0)
for (i in 0..51) ranks[i] = i % 13
var war = Fn.new {
var deck = List.filled(52, 0)
for (i in 0..51) deck[i] = i
rand.shuffle(deck)
var hand1 = Deque.new()
var hand2 = Deque.new()
for (i in 0..25) {
hand1.pushFront(deck[2*i])
hand2.pushFront(deck[2*i+1])
}
while (hand1.count > 0 && hand2.count > 0) {
var card1 = hand1.popFront()
var card2 = hand2.popFront()
var played1 = [card1]
var played2 = [card2]
var numPlayed = 2
while (true) {
System.write("%(cards[card1])\t%(cards[card2])\t")
if (ranks[card1] > ranks[card2]) {
hand1.pushAllBack(played1)
hand1.pushAllBack(played2)
System.print("Player 1 takes the %(numPlayed) cards. Now has %(hand1.count).")
break
} else if (ranks[card1] < ranks[card2]) {
hand2.pushAllBack(played2)
hand2.pushAllBack(played1)
System.print("Player 2 takes the %(numPlayed) cards. Now has %(hand2.count).")
break
} else {
System.print("War!")
if (hand1.count < 2) {
System.print("Player 1 has insufficient cards left.")
hand2.pushAllBack(played2)
hand2.pushAllBack(played1)
hand2.pushAllBack(hand1)
hand1.clear()
break
}
if (hand2.count < 2) {
System.print("Player 2 has insufficient cards left.")
hand1.pushAllBack(played1)
hand1.pushAllBack(played2)
hand1.pushAllBack(hand2)
hand2.clear()
break
}
played1.add(hand1.popFront()) // face down card
card1 = hand1.popFront() // face up card
played1.add(card1)
played2.add(hand2.popFront()) // face down card
card2 = hand2.popFront() // face up card
played2.add(card2)
numPlayed = numPlayed + 4
System.print("%("? ")\t%("? ")\tFace down cards.")
}
}
}
if (hand1.count == 52) {
System.print("Player 1 wins the game!")
} else {
System.print("Player 2 wins the game!")
}
}
war.call()</lang>
{{out}}
