They can take an iterative approach, or they can write a program that does Java factorial recursion. For those who aren’t math wizards, the factorial of a number is the product of all the whole ...

It's also worth noting that support for tail recursion makes tail recursive and iterative loops equivalent, that is, recursion doesn't always have to waste the stack. Also, a recursive algorithm ...
