Good day, Codeforces! Or in my language, magandang araw, Codeforces!
Of course, this round is not made by me alone. So, I would like to thank the following people for their help in making this round possible:
- coordinator PikMike, for coordinating my round even when he was very busy;
- testers antontrygubO_o, McDic, 300iq, adedalic, isaf27, farmersrice, NeverBeNutella, Vovuh, CaseRuten,Stresshoover, ZeroAmbition, Pavlova, defolaut, and Arpa, for testing problems and giving very valuable feedback;
- and of course, MikeMirzayanov and Codeforces staff, for providing us with the amazing Codeforces and Polygon platforms!
There will be 6 problems, and you will be given 2 hours to solve them.
The scoring distribution is as follows: 750-750-1250-1750-2250-2500.
I hope you enjoy the round!
