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.

What we have learnt
- Recursion involves breaking down problems into smaller subproblems of the same type.
- Each recursive function must have a base case and a recursive case to function properly.
- While recursion can simplify code for hierarchical problems, it may also lead to increased memory usage and performance issues.
Key Concepts
- -- Recursion
- A programming technique where a function solves a problem by calling itself with a reduced version of the original problem.
- -- Base case
- The condition under which a recursive function stops calling itself, preventing infinite recursion.
- -- Tail recursion
- A special case of recursion where the recursive call is the last operation in the function, which can be optimized by some languages.
- -- Memoization
- A technique used to optimize recursive algorithms by storing previously computed results.
