Hello, Codeforces!
The 2026 ICPC Gran Premio de Mexico Repechaje was held two weeks ago. This is part of the 2026–2027 ICPC subregional season and the final contest of the 2026 Mexico Grand Prix, a series of cumulative contests for teams from Mexico and Central America to qualify for the Mexico Regional Contest.
Huge thanks to the problem authors: yongwhan, Bashca, racsosabe, Baus, wiritos, Juan Pablo Marin Rosas, Eddy Ramírez Jiménez and me (IvanBorquez).
I would also like to thank the systems director for making it possible to have a platform for the contest Franco1010, and the chief judge, Juan Pablo Marin Rosas, for adapting the problems to the official platform, preparing the problem books.
You can check the editorial (in Spanish) for the contest at the following link.
Feel free to use the comments to discuss the problems.
Good luck and have fun!
