Hello Codeforces! :3

Yesterday, our small community in Mansoura held its traditional contest Game of Coders for the third year. And we are very glad to bring you the contest on Codeforces c:

The mirror contest will be held on Tuesday $$$16^{\tiny{\mbox{th}}} $$$ July 2024 at 19:05 UTC+3.

You will be given 5 hours to solve 13 problems that I have prepared (I hope they are all original). The contest is ICPC style with 20 minutes penalty for each incorrect submission, and problems are not sorted by difficulty, so read all the problems carefully. :3

This is my first time creating a full problemset, and it was a very fun (and exhausting) experience, and I would like to thank the people who I couldn't have done it without:

• TripleM5da, Hagry, no-you-didnt, Khaled_Hegazy, SaraXorSaraXorSara, 0xEmadeddin for testing and saving the day.
• MikeMirzayanov for Codeforces, Polygon, and Testlib.
• ICPC Mansoura Community for amazing organization of the event.
• Yansoon for helping me write the announcement.
• Finally, The Secret Partner for existing.

Hope you enjoy the contest and have fun solving problems. <3

UPD: The editorial (not really, just the codes) is finally out! I'll prepare hints and solutions and edit the blog later, hopefully. :3
