The title explaines it all. I have been studying for my exam all day, and I have faced the truth: I cannot come up with recursive solutions.

Actually, I understand how recursion works and solve output(or similar code-reading) problems. But when it comes to solving a problem in a recursive way, I have severe difficulty in developing a solution.

I wanted to ask if there is a specific way to study recursion. I mean, the best way is solving as many problems as I can, but still maybe you can give some advices about recursion. Even though it is too late for the exam, I do not want to put recursion aside.
