Hi all. My problem is not about code, it's not that my code is not working. It's that I don't have a code at all. I don't have an idea for an algorithm to solve the following question: I need to write a program that rotates a number (for example, 1234) one turn to the right (to get 4123). Easy right? wrong. I need to do this recursively, and really, I have no idea how to solve this rather simple problem recursively. I'd appreciate any ideas or suggestions...I'm stumped.

What do you mean by "recursively"?
