For Part 1 we just need a BBC micro:bit... but this will be inadequate to display our card game, so we will use additional hardware in Part 2

// TESTING: -----------------------------------------

input.onButtonPressed(Button.A, function () {
    for (let index = 0; index <= 4; index++) {
        basic.showNumber(playerHand[index])
        basic.showString(".")
    }
    basic.showIcon(IconNames.Yes)
})
input.onButtonPressed(Button.B, function () {
    startNewHand()
    basic.showNumber(handsPlayed)
    basic.showString("X")
    basic.showNumber(numberPackShuffles)
    basic.showIcon(IconNames.Yes)
})

// Shuffling and resetting deckOfCards -----------------------------------------
// 
// very generic - no changes should be required here for different games.
function shufflePack () {
    resetPack()
    for (let loopX = 0; loopX <= packSize - 1; loopX++) {
        cardChosen = randint(0, originPack.length - 1)
        deckOfCards.insertAt(loopX, originPack.removeAt(cardChosen))
    }
    activeCard_PackPosition = 0
    numberPackShuffles += 1
}
function getDealtCard () {
    if (activeCard_PackPosition >= 52) {
        shufflePack()
    }
    return deckOfCards[activeCard_PackPosition]
}
function resetPack () {
    originPack = [packSize]
    for (let loopX2 = 0; loopX2 <= packSize - 1; loopX2++) {
        originPack[loopX2] = loopX2
    }
}

// EDITABLE FUNCTIONS:-----------------------------------------------------------
// 
// When you build your card game the functions below will need to be adapted. It
// is likely you will need to implement these functions in some form: they are generic
// to the architecture of any card game.
function startNewHand () {
    handsPlayed += 1
    playerHandSize = 0
    for (let index = 0; index <= 4; index++) {
        playerHand[index] = getDealtCard()
        activeCard_PackPosition += 1
        playerHandSize += 1
    }
}
/**
