新Swiftで行こう…第２１回「ポーカー６」 田部井保
前回の問題は、ペアの詳細を判別出来ないかという事でした。
前回の問題の答えの一つです。

}
}
if chk {
let alert = UIAlertController()
alert.title = "フラッシュ"
alert.message = "フラッシュです"
alert.addAction(UIAlertAction(title: "OK", style: .default))
present(alert, animated: true, completion: nil)
} else {
var ck = 0
for i in 0 ..< 5 {

}
var msg: String
switch ck {
case 1:
msg = "ワンペア"
case 2:
msg = "ツーペア"
case 3:
msg = "スリーカード"
case 4:
msg = "フルハウス"
case 6:
msg = "フォーカード"
default:
msg = ""
}
if ck > 0 {
let alert = UIAlertController()
alert.title = "ペア"
alert.message = msg + "です"
alert.addAction(UIAlertAction(title: "OK", style: .default))
present(alert, animated: true, completion: nil)
}
}
}
@IBAction func btnGoTouch(_ sender: Any) {
for i in 0 ..< EnumCard.Count {
check[i] = false
}
count = EnumCard.Count
for i in 0 ..< 5 {
put(i: i)
}
flush()
}
@IBAction func btnReTouch(_ sender: Any) {
for i in 0 ..< 5 {
if eachButton[i].currentTitle == "on" {
put(i: i)
eachButton[i].setTitle("off", for: .normal)
}
}
flush()
}
}このように役の判定はとてもシンプルに出来ます。もちろん他の方法でも良いです。
ここで、ペアがあったら、フラッシュ、ストレート（番号が5つ並ぶ）はなく、ペアが無い場合にフラッシュとストレートがある可能性があります。フラッシュとストレートは同時に起こる可能性もあります。作って来たシステムでは、フラッシュかどうか調べ、フラッシュでなければペアを調べるという形になっています。ここは、まずペアかどうか調べ、ペアでない場合に、フラッシュ、ストレートを調べるという形にします。とりあえず、ストレートは後回しにして、フラッシュとペアを入れ替えます。

}さて問題です。ストレートを判定するにはどうすれば良いでしょう。ストレートとは5枚が連番になる組み合わせです。本来ストレートはK(13)の次にA(1)が続くのですが、今回は、Kの次にAが続かないとして良いです。AからKまでの中で続いていたらストレートとします。
