This prevents infinite loops. Point is, make sure you're extremely concrete. target number the number we know the step to the next element. At least it will keep the kids quiet until they get bored (or is that the base case?). Let me demonstrate this by calculating the sum of all the elements of a list recursively: sacrificing some of the nuances of it. Before we get in to the how we are going to convert that defintion to a program, let me give you a example as requested, that I believe can explain and help you get the idea for the need of recursion in programming.

With this intuitive, cloud-based solution, everyone can work visually and collaborate in real time while building flowcharts, mockups, UML diagrams, and more. Another good one can be found on "The C Programming Language" (Kernighan and Ritchie). Be realistic about how much you can explain to a non-technical audience with a single presentation or interaction. We know that the method we have made is recursive (and therefore an example of recursion) because in our method was called factorial and in it we call a method called factorial.

It will help give you a home base for direction, so if you start to sway too deep into a topic, you can pull yourself back and cater to the needs of the listener.
