Bowling Score Calculator

This Ruby application is designed to calculate the score of a standard ten-pin bowling game. It takes a series of rolls as input and outputs the score for each frame.

Features

• Handles all standard bowling scoring rules, including strikes, spares, and open frames.
• Accurately calculates scores for incomplete games.
• Provides error handling for invalid roll sequences.

Validations

• Rolls Format: Accepts only numbers between 0-9, 'X' for strikes, and '/' for spares. Invalid input will raise an error.
• Spare as First Roll: A spare ('/') cannot be the first roll of a frame. An error is raised if this rule is violated.
• Strike Followed by Number: A strike ('X') cannot be followed by a number in the same frame. This sequence will trigger an error.
• Spare Followed by Strike in Strike Bonus: In the strike bonus calculation, a spare ('/') cannot follow a strike ('X'). An error is raised if encountered.
• Spare Followed by Spare in Spare Bonus: In the spare bonus calculation, a spare ('/') cannot follow another spare. This will result in an error.

These checks ensure that the input adheres to standard bowling rules.
