Which principle does Karel utilize to effectively solve problems in programming?

Karel effectively solves problems in programming by creating detailed and clear functions. This principle is essential because well-defined functions allow for better organization, readability, and reusability of code. When functions are created with clarity and specific purposes, it becomes easier to break down complex problems into manageable components. This modular approach not only enhances the understandability of the code but also enables Karel to solve tasks more efficiently by leveraging these functions multiple times throughout a program.

Moreover, clear functions help in debugging and maintaining the code, as each function can be tested independently to ensure it performs its intended task. This focus on creating detailed functions leads to a more structured and logical flow in programming, facilitating problem-solving and allowing for easier adjustments as needed.
