Q. Implement a function product() to multiply 2 numbers recursively using + and - operators only.

You can understand by Watching video :-

Answer =

def product( num1 , num2 ):
    if 0 == num2 :
        return 0
    else :
        return product(num1 , num2 - 1 ) + num1

a = int(input("Enter a number : "))
b = int(input("Enter second number :"))
print(product( a , b))

Output :-

Enter a number : 5
Enter second number :6
30
>>> 

Enter a number : 75
Enter second number :2
150
>>> 

Enter a number : 10000
Enter second number :89
890000
