Implement pow(a,b) without multiplication or division

This is one type of very common interview question that is usually asked, where your goal is to implement some built-in language function, such as exponentiation, division, hash tables, etc. In this challenge we need to implement exponentiation, or raising **a** to some power of **b** which is usually written pow(a, b). In this variation of the challenge, we also need to implement a solution without using the multiplication or division operations, only addition and subtraction are allowed.
## Example of how pow(a, b) works
