Design a Tennis Scoring System

Problem Statement

Design a class TennisMatch to track the score of a standard tennis game between two players, "Player A" and "Player B". Your class should expose a method to register a point win and a method to retrieve the current score in the standard tennis format.

Scoring Rules

1. Points are scored in the sequence: 0 (Love), 15, 30, 40.
2. If both players reach 40, the score is "Deuce".
3. After Deuce, the next point gives the player "Advantage".
4. If a player with Advantage wins the next point, they win the game.
5. If the player with Advantage loses the point, the score returns to "Deuce".
6. A player wins the game if they score 4 points (and the opponent has 2 or fewer) or if they win from Advantage.

Requirements

Implement the following interface:

class TennisMatch:
    def __init__(self):
        # Initialize match state
        pass

    def point_won_by(self, player_name: str) -> None:
        # Update the score based on who won the point
        pass

    def score(self) -> str:
        # Return current score as a string (e.g., "15-30", "Deuce", "Advantage Player A")
        pass

Examples

• Input: match.point_won_by("Player A"), match.point_won_by("Player A") -> Output: "30-Love"
• Input: After 40-40, match.point_won_by("Player B") -> Output: "Advantage Player B"

Constraints

• You do not need to track sets or matches, only a single game.
• Assume player_name is always either "Player A" or "Player B".
• The game ends immediately once a player wins.
