Project Euler #125

It is interesting how I analyzed this problem --> first attempt was doing an horrible brute force which  would take milliards of years to complete.

Classical problem, where I had to re-design the solution, after getting a couple of "duplicate numbers" (also incorporated to the problem). Simple & Hard. This is the taxonomy of problems I must create.

My performance is a little slow:
