2. Calculate Factorial using Iteration Simple and the most basic version to find the factorial of a number. publicstaticlongfactorialIterative(longn){longr=1;for(longi=1;i<=n;i++){r*=i;}returnr;} 3. Calculate Factorial using Recursion Using plain simple recursion may not be a good idea...

of course, I could save myself a lot of computations. One way to do this is to use recursion, but if we’ve already calculated the value, store it away for future use. Thus (using HashMap, because it’
(n); } catch { throw; } } public static int Recursion(int n) { if (n < 0) { throw new ArgumentOutOfRangeException(); } try { int factorial = 1; if (n >= 2) { checked { factorial = n * Recursion(n - 1); } } return factorial; } catch { throw new ArgumentOutOfRange...
This function is said to be defined recursively. The first condition needed for recursion definition is thebase case. This is the point at which the recursive calls will stop. In the factorial example this will be when zero factorial (0!) is reached. ...

In this tutorial, we'll learn how to calculate a factorial of an integer in Java. This can be done using loops or recursion - though recursion is arguably a more natural approach. Of course, you should implement the one you're more comfortable with. Calculating Factorial Using Loops Let's...
