Last week I tried solving Tuenti’s 1st programming contest, but even the challenges were somewhat easy and fun to solve, I got increasily busy with work-related things and had to drop. Now I have published on CodePlex the solutions for challenges 1 to 6, solved using C# and .NET 4.0. So, if you want to take a look or just see how other people figured it, give them a try. The current upload is hasty, “as-is” code, and I’ll try to comment it and/or minimally document in the following days.
