Well, recursion is just a function calling itself. In theory, it shows how a problem can be broken into identical subproblems, which is a core algorithmic idea. But the real insight comes from how you manage the call stack and avoid infinite loops. It’s not magic, just a pattern that repeats. If you want a deeper lesson, look at tail recursion or memoization. Otherwise, it’s just a neat trick.

I’d prefer to pull the stack clean and finish the problem, not just keep pushing new copies. If it’s a real issue, let’s look at the base case and termination condition first. Otherwise we’ll just end up in an endless loop.
