Hello!

I invite you to participate in the 26th Spain's Olympiad in Informatics' Online Mirror. This is the first year we are doing the mirror contest and we hope it will be a success. The two contests will start on 2022 April 2 16:00 CEST and 2022 April 3 16:00 CEST and will last 4 hours each.

Contest facts:

  • Two 5-tasks contests with OI scoring (subtasks).
  • Statements in English and Spanish.
  • Problems are not ordered by difficulty.
  • Problem authors: FelixMP EdgarMM19 BlancaHM gog.gerard
  • The problems will cover a wide range of difficulties, and the subtasks make it possible to progress in all problems, so it should be an interesting contest for participants of all skill levels. For reference, see last year's problems here and here.
  • The allowed languages will be C++, Java and Python.

In order to participate in the contest, you must register using this form (use a translation service if you do not understand something). The contest will be held in a CMS platform and you will receive your credentials and instructions for participating in the email you provided on the form. The deadline for registering is 26 March.

Good luck and enjoy the problems!

Los problemas del año pasado fueron muy interesantes. Estoy segura de que los problemas de este año serán buenos. ¡Buena suerte! (Spanish is not my native language, hopefully I didn't have grammar errors)

Hello, hope you all enjoyed the problems. Answering some questions:

  • There is not a full editorial, but there are some documents here in Spanish explaining very briefly the main ideas behind the solution of the problems, with the code of the official solution.

  • Here you can see the standings of the onsite contest if you want to check how you did against the actual contestants. If you participated in the mirror contest, you should have received a copy of the mirror contest standings to your email.

  • If you participated in the mirror contest, you also should have access to problems for upsolving. At some point, we will publish them somewhere so everyone can submit.
