Multiplication Without Using * Operator

Problem statement

In this problem, we need to find the result of the multiplication of two numbers, a and b but without using * operator. This looks like a pretty simple problem. We can easily iterate a loop from 1 to b and add a to our result. But there is a catch: you need to write a solution with a Recursive approach.

Implementation

Let’s write the solution first, and then visualize how recursion is working.
