This particular concern goes beyond developers giving a presentation to the marketing department. The idea used by compilers to optimize tail-recursive functions is simple since the recursive call is the last statement, there is nothing left to do in the current function, so saving the current function's .

To break the ice, jokingly acknowledge the fact that youre a computer nerd or tech geek and apologize in advance if you get too technical. Boxes inside of boxes. In other words, a factorial is just our main number multiplied by the factorial of the next number down from it. The techniques for executing recursive functions are well-known: each function call has a piece of memory, called a stack frame. In the same manner as you would any other informationin a clear and compelling way. Then use various "basic shapes". Don't try it with mathematics or whatever the other people here are suggesting. This is a technical article catered to developers, technical project managers, and other technical staff looking to improve their skills. Recursion is the repeated sequential use of a particular type of linguistic element or grammatical structure. Visual content is easier to learn and more frequently recalled than concepts learned by reading or just being told.

Using a few of them can elevate any industry-specific topic and make it accessible for the general population. 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). As such, tail recursive functions can often be easily implemented in an iterative manner; by taking out the recursive call and replacing it with a loop, the same effect can . (That is, it is a heap except that its root might not be larger than that of its children.) Heres the second way in pseudocode.
