Math

This problem arose a couple of months ago in a competition at work. I promised I'd work on it, so here it is.

I'm back after a long break. This time there are some trivial problems and a couple of math related ones.

Back to c++ and Topcoder! Another set of simple problems while I try to get on schedule and think on how to solve a couple of harder problems.

Finally, after a sequence of major things (that Murphy himself seems to have devised) that stopped me from continuing with the challenge , I'm back with some more problems. A very nice math problem, a cute scala implementation and some easy python problems this time.
