It was my turn to organize the session today. My friend M didn't have much time, so it was a short one.
I explained to M how programming contests (coding) goes, and today I suggested him to solve a problem. I use the "Programming Challenges" book by Steven S. Skiena and Miguel A. Revilla (from Springer). I picked the problem "Minesweeper" from sect. 1.6.2 (PC/UVa IDs: 110102/10189). He works as a programmer and he's played Minesweeper (which allegedly used to be the most frequently used application on some OS...) before.
It's a basic problem, so he got rough idea of what needs to be done pretty quickly. So next time we're going to discuss how to implement his solution
