Factorial Using Recursion

Let's start with Main Class

public static void Main(string[] args)
{
    //Your code goes here
    int i = 5;
    Console.WriteLine("Recursive number of " + i + " is " + factorial(i));
}

Now we will create factorial function. Always start with the base condition, or when condition is stopped.

public static int factorial(int angka)
{
    if(angka == 1)
    {
        return angka;
    }
    else
    {

    }
}

If the number not met with base condition, we will doing recursion.

public static int factorial(int angka)
{
    if(angka == 1)
    {
        return angka;
    }
    else
    {
        return angka*(factorial(angka-1));
    }
}
