Egyptian National Contest 2009 Problem Set Analysis

[Khaled Hafez]

Hello contestants,

I hope you enjoyed the national competition. I'm glad to see that we have many strong teams this year.
I would like to congratulate Cairo University teams for dominating the scoreboard, and applaud to "FCI-Cairo Univ. 1" team for their amazing performance!

Please see the attached problem set analysis. It will come in handy if you are still wondering about the solution of one of the problems or wondering why you kept getting wrong answers in another one of them. I have also attached the actual problem set in case you lost your copy.

Please feel free to send me any questions/comments regarding the document.

I wish you all the best of luck in the regional contest this year.

Regards,
Khaled

Thanks for the analysis!

Anyone knows where can I find the judge's I/O for the problems? It is not published here yet.
