The four sub-requirements are what make this interesting.
Start by clarifying requirements and edge cases, then design a flexible Logger class using composition or strategy pattern to support multiple behaviors. Implement each behavior as a separate method or decorator, and demonstrate with a simple example. Discuss trade-offs between different design choices.
Pro tip: Mention that behaviors should be composable and order-independent where possible, and consider using a pipeline of transformations for extensibility. Also, highlight the importance of thread safety if the logger is used in concurrent environments.
Ask questions to understand expected inputs, behavior interactions (e.g., stripping then truncating), and whether behaviors can be combined. Clarify if the logger is for production or just an exercise.
Decide on an interface with methods for each behavior (e.g., strip, truncate, uppercase, store) and a log method that applies configured behaviors. Consider using a list of transformation functions or a builder pattern.
Write code for each behavior as a pure function that takes a string and returns a modified string. Ensure the log method applies transformations in a defined order and handles storage separately.
Provide a simple usage example showing each behavior individually and in combination. Mention unit tests for edge cases like empty strings, overlapping substrings, and max limit boundaries.
Talk about pros and cons of your design: e.g., flexibility vs. simplicity, performance implications of string operations, and how to add new behaviors without modifying existing code.
