Rekursif : Calculating the Value Program with Recursive Factorial (Program Menghitung Nilai Faktorial dengan Rekursif)

In mathematics, the factorial of n natural numbers is the result of multiplication of positive integers less than or equal to n. Factorial written as n! and is called n factorial.

For example, 5! is worth 5×4×3×2×1 = 120.
