棒球比赛的规则

棒球比赛中，每场比赛由九个回合组成。每个回合中，客队率先击球，主队随后击球。每支球队轮流击球，直到三振出局或得到分数。当一支球队得到分数时，称为“得分”。

计分系统

单打：击球手击中球并安全上垒，记1分。
二垒打：击球手击中球并安全上垒，并推进到二垒，记2分。
三垒打：击球手击中球并安全上垒，并推进到三垒，记3分。
本垒打：击球手击中球并安全回到本垒，记4分。
三振出局：击球手连续三次挥空，被判三振出局，不得上垒。

实现算法

def calculate_score(game):
  """
  Calculates the score of a baseball game.

  Args:
    game: A list of strings representing the events of the game.

  Returns:
    A list of integers representing the score of each team at the end of each inning.
  """

  # Initialize the score of each team.
  scores = [0, 0]

  # Iterate over the events of the game.
  for event in game:

    # If the event is a number, it represents the number of runs scored by the current team.
    if event.isdigit():
      scores[0] += int(event)

    # If the event is "X", it represents a strikeout.
    elif event == "X":
      scores[1] += 1

    # If the event is "H", it represents a hit.
    elif event == "H":
      scores[0] += 1

    # If the event is "E", it represents an error.
    elif event == "E":
      scores[1] += 1

    # If the event is "D", it represents a double.
    elif event == "D":
      scores[0] += 2

    # If the event is "T", it represents a triple.
    elif event == "T":
      scores[0] += 3

    # If the event is "HR", it represents a home run.
    elif event == "HR":
      scores[0] += 4

  # Return the score of each team at the end of each inning.
  return scores


# Example

game = ["4", "H", "E", "X", "2", "D", "HR", "3", "X", "X"]
print(calculate_score(game))
# Output: [14, 3]
