End of Round 5

I hope you all enjoyed our last round for a while. Unfortunately there was an error in one of the test cases for #4, making the maximum possible achievable mark a 4/5. We apologize for any inconvenience this may have caused. Apart from that this round seems to have run smoothly. We'll most likely have summaries of the solutions to the problems up CompSci.ca sometime in the next couple of days, so keep an eye out for that.
