    Haha! If I had been at home for the announcement I would have shocked you 😉 My solution to http://projecteuler.net/problem=96 is by no means complete, nor bug free, but I’ll submit it all the same. I wish I had more time to enter the challenges, but https://www.edx.org/course/mit/6-00-1x/introduction-computer-science/1122 and https://www.edx.org/course/mit/6-002x/circuits-and-electronics/1130 may be of interest to people here.

      interesting the problem 96 link does not open
      the background of this challenge is that my son is student and he got this as homework few monthes ago, but he couldn’t solve it and searching the net didn’t show solution too 🙂
      I helped him with lazy brute force solution, but I’m sure there are more elegant solutions too

        Actually the way it (is supposed to!) works is that you get the challenge, but abide by an honour code to solve it yourself. A great way to practice using a new language, as are your challenges also!
