Question

Write a recursive method called, doMyMath, which takes as input any positive integer and calculates the factorial (use comments for necessary items).

Answer 1

Answer:

def doMyMath(n):  

    if n == 1:  

         return n  

    else:  

         return n*doMyMath(n-1)  

Explanation:

This line defines the function

def doMyMath(n):  

This line checks if n is 1. If yes, it returns n (1)

    if n == 1:  

         return n  

If otherwise, it calculates the fibonacci recursively

    else:  

         return n*doMyMath(n-1)  

To call the function from main, you can use:

print(doMyMath(5))

or

num = int(input("Number: "))   --- This gets the number from user

print("Result: ",doMyMath(num)) --- This calculates the factorial
