Chapter 12.3, Problem 16SCP

Explanation of Solution

Recursive method:

• A technique where an algorithm is described in terms of itself is called as recursion.

Iterative method:

• A technique where actions gets repeated using a loop is called as iterative method.

Converting the given iterative method into recursive method:

//method definition

public static int factorial(int n)

{

    //condition to validate the value

    if (n == 0)

    {

        //return 1

        return 1;
