Facebook Hacker Cup 2012: Qualification Round

This past weekend the Facebook Hacker Cup 2012 took place. I found it was very well organized, and everything was working fine, including the submissions and the scoreboard. If you haven’t participated this year, I highly recommend you do so next year.

The qualification round consisted of 3 problems, and any participant solving at least one of them correctly would pass to the first official round (which will take place on January 28).

I found two out of the three problems relatively easy to solve. The third one was quite difficult though. I ended up qualifying in position 819, out of 6000 or so participants who also qualified to the next round.


Below you’ll find a link to the problems and my solution:
