Hola Codeforces!

The 2023 Argentinian Programming Tournament (TAP) was held last weekend. This is a 2023-2024 ICPC subregional contest for teams from Argentina to qualify to the South America/South Regional contest. You can send your solutions or do a virtual participation in the Codeforces gym. I invite you all to solve the problems.

The problems were written and prepared by elsantodel90, fredy10, Guty, lsantire, pablobce and me (MateoCV)

I would like to thank MarcosK for solving and reviewing the problems and providing valuable feedback.

Feel free to use this blog to discuss about the problems :)

Happy coding!
