This explain pretty much the concept of recursion. Like, number of legos in a box after applying the next step in the algorithm (which I'd advice to call something less scary, such as a turn or a step). Recursion is a powerful technique that helps us bridge the gap between complex problems being solved with elegant code. If Pokemon could call himself from Pokeball that would be recursive call (Did he watch Pokemons?). Example of a real world recursion: Sometimes this means coming up with useful analogies that explain an idea in a way that is relatable.

Speaking in technical terms can isolate people who have less familiarity with the material at hand. It's too abstract and boring for them. (divide and conquer) then use a simple visual example side by side with the code to explain how this relates to recursion in code. Those same software engineers often have all of the raw material to be great communicators. One way to ensure that you start out at the right level of explanation is by asking the listener what they do and dont already know. Are you sure you want to hide this comment? Do it properly, and the chances of success are so much higher. This particular concern goes beyond developers giving a presentation to the. Here is a recursive function to calculate the factorial of a number: Now lets see what happens if you call fact(3) The illustration bellow shows how the stack changes, line by line. Concerning the "why you would use it": Does this matter to non-programmers? Let me demonstrate this by calculating the sum of all the elements of a list recursively: One way to ensure that you start out at the right level of explanation is by asking the listener what they do and dont already know. In this tutorial, you will learn to create a recursive function (a function that calls itself). The infinite mirrors example works as well as a tangible example. Focus on the initiatives and pain points that your audience cares most about, and your interactions will have a much greater impact with executives and other non-technical employees at your organization.
