What is Recursion

# What Is Recursion? A Beginner's Guide with Examples (Modern C++) Have you ever thought about how a problem can be solved by breaking it down into smaller, self-similar instances? That's the magic of recursion! Recursion is a powerful programming technique where a function calls itself to solve a problem. It's like a set of Russian nesting dolls, each containing a smaller version of itself. Understanding recursion is crucial for mastering algorithms and data structures, opening doors to ele
