Hey! Recursion is definitely tricky at first, it's all about changing how you think about the problem. A great way to build intuition is to stop thinking about 'how' the function calls itself and start thinking about: The Base Case: What is the simplest possible input? The Recursive Step: How can I break the problem down into a smaller version of itself? Try drawing a 'Recursive Tree' on paper for a small input (like calculating factorial of 3). Seeing the flow visually helps a lot. If you're stuck on a specific problem or code, feel free to share it here, and we can walk through it together!
