Я пытаюсь разработать карточную игру, как показано:
- В начале игры каждый игрок по очереди берет карту из перетасованной колоды из 52 карт. Игроки должны иметь одинаковое количество карт.
- Например, если есть 5 игроков, то каждый игрок получит 10 карт. Затем игра продолжается раундами.
- В каждом раунде каждый игрок разыгрывает карту. Игрок, который разыгрывает самую крупную карту, выигрывает. Порядок карт, которые разыгрывает игрок, является порядком получения карты.
- Например, если Алиса др aws S5, D2, HK, SA, C4 в этом порядке, она сыграет S5 в первом раунде, D2 во втором раунде и т. Д.
Проблема : В классе CardGame у меня возникли проблемы с методом play () . В // разрабатываем l oop для каждого раунда , мой подход состоит в том, чтобы создать 2 списка массивов и в конечном итоге распечатать имя победителя раунда:
- сравнение1 список массивов для хранения сыгранных карт
- сравнение2 список массивов для хранения сравниваемых карт из сравнения список массивов
Однако, я получаю ошибку:
