    {
        static void Main(string[] args)
        {
            Random rand = new Random();
            int aiChoice = rand.Next(0, 3);//0~2 사이의 랜덤 값
            bool isWin;

            int choice = Convert.ToInt32(Console.ReadLine());
            switch(choice)
            {
                case 0:
                    Console.WriteLine("당신의 선택은 가위입니다.");
                    break;
                case 1:
                    Console.WriteLine("당신의 선택은 바위입니다.");
                    break;
