My coworker sent me this fun website of programming projects to do. They are math related so you know the formula to help optimize your solution, even better for you. Each project has a question that involves some mathematics and you get a submission form to submit your answer to see if you are right.
The website is at http://projecteuler.net/ and I really recommend anyone to register and go down the list of projects to do. I’m doing mostly in java at the moment but I would love to try using C# as well as some of the other variants built on java like groovy or scala.
So far I’m on project 3 and having a blast solving these problems!
