## Round 1 - Coding ## Problem Design and implement a simplified card game engine. You are given a standard 52-card deck. Players take turns drawing and playing cards. Implement the core game loop. ```python class Card: def __init__(self, suit: str, rank: str): ... class Deck: def shuffle(self) -> None: ... def draw(self) -> Card: ... class Player: def __init__(self, name: str): ... def play_card(self, index: int) -> Card: ... class CardGame: def __init__(self, players: list[Player]): ... def start(self) -> None: ... def get_winner(self) -> Player: ... ``` ``` Example: game = CardGame([Player("Alice"), Player("Bob")]) game.start() # Each player draws 5 cards; highest-rank card wins each round. # After 5 rounds: winner = player with most round wins game.get_winner() -> Player("Alice") ``` ## Follow-ups 1. How would you handle ties when two players play the same rank? 2. Extend to support 4 players - what changes in your design? 3. How would you make the game rules configurable (e.g. swap rule engine)? 4. If game state must be persisted mid-round, how do you serialize it?
