   How to calculate a factorial if a number is not zero?

   • We again start by checking if the input number is zero, and if it is, we return 1. If the number is not zero, we multiply the number by the factorial of one less than the number. This is done by recursively calling the factorial_recursive function with the argument n - 1. For example, the factorial of 5 using this function would be calculated as:
