I need a recursive Python algorithm that multiplies two numbers through successive sums

Question

Multiplication must be done by successive sums, 6x4= 4+4+4+4+4+4+4+4

Program entry: 6 4 Output from the program: 24

Answer 1

First you need to create a function with two parameters (factor and multiplying). In the case how the function is recursive, I will name the parameters as x and times.

Within this function you must create a condition to check whether the parameter times is greater than zero. It is this parameter that will tell how many times more the function should be called.

If the parameter is greater than zero, the function should return the value of x added to the call return of the same function with the same parameters, however, the argument value times shall have its value decreased.

If the variable value times is equal to zero, the function must return the value zero. Thus, the final result will be the sum of the returns of all the calls until times is equal to zero.

def mult(x, times):   
    return x + mult(x, times - 1) if times else 0
