Hello Competitors,

I would like to invite you all to participate in the follow up of Third Coding Marathon of Princess Sumaya University for Technology. The contest was originally held on April 30, and it will launch in Codeforces Gym tomorrow; May/07/2016 10:00.

The problems were prepared by Hasan0540, SaMer, and Dr. Ibrahim (earlgray).

The contest will be held with extended ACM ICPC rules. You'll be given 14 problems to solve within 270 minutes. Some of the problems have two parts (A and B), where A is easier than B, and the statement of B depends on the statement of A. The difficulty of the contest is similar to Codeforces Div. 2 contests.

Good luck to you, and I hope you can enjoy the problemset.

Note: Don't forget to use fast I/O methods.
