Write a Python program to multiply two integers without using the * operator in python

The program defines a recursive function multiple that takes two integers a and b as arguments and returns their product. The function works by repeatedly adding a to itself b times using recursion, until the value of b becomes 1, at which point the function simply returns a. If the value of b is negative, the function calls itself with b replaced by its absolute value and the sign of the result is negated. If b is 0, the function simply returns 0.

In the main program, the user is prompted to enter two integers a and b, which are then passed as arguments to the multiple function. The result of the multiplication is then printed to the console.

Source Code

def multiple(a,b):
	if b < 0:
		return -multiple(a, -b)
	elif b == 0:
		return 0
	elif b == 1:
		return a
	else:
		return a + multiple(a, b - 1)
 
 
a = int(input("Enter the Number :"))
b = int(input("Enter the Number :"))
print(multiple(a,b))

Output

Enter the Number :12
Enter the Number :34
