WebMar 23, 2024 · Calculating Factorial Using Recursion A recursive method is a method that calls itself and terminates the calls given some condition. In general, every recursive method has two main components: a base case and a recursive step. Base cases are the smallest … WebDirect recursion is one way that reentrancy can happen. We’ve seen many examples of that during this reading. The factorial() method is designed so that factorial(n-1) can be called even though factorial(n) hasn’t yet finished working. Mutual recursion between two or more functions is another way this can happen – A calls B, which calls A ...
