6. Demonstrate Proficiency in Recursive Problem-Solving

Recursion is a fundamental programming technique in which a function calls itself to solve smaller instances of a problem. It effectively simplifies complex problems, such as tree traversals and mathematical calculations, although it can introduce challenges like higher memory usage and slower performance compared to iterative approaches. Mastery of recursion requires practice in defining base cases and recursive strategies, which enhance problem-solving capabilities in various programming domains.
