Java factorial recursion explained Notice how the recursive Java factorial function does not need an iterative loop. Instead, the code repeatedly calls itself until a stop condition is met. In this ...

This is one of the most common examples of the need for recursive functions. Recursive functions, at their simplest, are functions that call themselves. These types of functions are used in the ...

Recursion has more expressive power than iterative looping constructs. I say this because a while loop is equivalent to a tail recursive function and recursive functions need not be tail recursive.
