Long multiplication algorithm with numbers that may be very large (may not fit in long long int). Should be done in C++.

Sould also have an addition and subtraction function to be able to use in the long multiplication algorithm.

- Needs to read two digit strings a and b. Should be done using VECTORS. The numbers a and b can be very large, for example, they can be thousands of digits -Need an algorithm that will multiplty a and b by brute force time complexity of Long multiplication algorithm with numbers that may be very large (may not (n^2). Also known as "third grade multiplication" or "pencil and paper multiplication". and output the result.
