RECURSION
The recursive functions, which form a class of computable functions, take their name from the process of “recurrence” or “recursion”. Recursion can be direct when an entity refers to itself directly or indirect. Recursion often allows easily expressing complex procedure, with often impressive results. Recursion is a programming technique that allows the programmer to express. For example, the natural numbers themselves are usually defined recursively.

This function uses recursion to compute factorials. I used some recursive definitions in my explanation of natural numbers and integers. What? It may be counterintuitive, but many turn-based.. Every recursive method must have a base case -- a condition under which no recursive call is made -- to prevent infinite recursion. Illustrated with examples: Factorial, Magic Squares, Tic-Tac-Toe (X&0).
