Hi everyone! I'm glad to announce that the registration process for Divisional Informatics Olympiad 2014 has finally started. Anybody eligible for this competition can register by going to the following link: Register here

If you are thinking what this olympiad is all about, it is an olympiad related to computer programming. However, you don't really need to be a pro in programming to participate in the divisional olympiad. In fact, divisional olympiad fully focuses on participants' analytic skills and has a paper based test only.

The event is to take place on 28 February, 2014 in 5 different cities. Participants will go through multiple selection process. After that, the best participants will participate in one of the most prestigious computer science competitions in the world, International Olympiad in Informatics (IOI) 2014, Taipei, Taiwan. (July 13-20, 2014)

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
