Racket walking

Racket walking is a method of moving a computer program efficiently through data structures like trees or graphs. It involves sequentially visiting each node or element in a systematic way, often using recursion or iterative algorithms, to process or analyze the data. This approach ensures all parts are covered without missing or repeating, making tasks like searching, sorting, or transforming data more organized and predictable. Racket, a programming language, provides built-in functions that facilitate this process, allowing developers to implement walking strategies that are clear, concise, and adaptable to complex data structures.
