Interesting though, that it is bad code, considering, that it is not written to be tail recursive. Maybe good to show the idea of fibonnaci numbers or a theoret

Interesting though, that it is bad code, considering, that it is not written to be tail recursive. Maybe good to show the idea of fibonnaci numbers or a theoretically valid implementation. But hopefully people do not accept this kind of code, thinking, that because it gets the result in some simple cases and it was suggested by copilot, it must be the way to properly do things.
