Hello Codeforces community!

I would like to announce Algoge Round 4. The contest will be held on Sunday 10th May at 15:00 UTC.

Algoge is site created by students of the Faculty of Computer Science during quarantine days in Serbia, based on the DMOJ platform. As there are no onsite contests these days, we decided to organize $$$5$$$ online rounds mainly for participants from Balkan. In the first three rounds, the tasks were only available on Serbian. Easier tasks were prepared by us and harder ones were taken from Moscow Workshop competitions. We had between 50 and 150 participants per round.

This is the first round fully created by us. For that purpose we decide to translate the tasks into English (Serbian version will be available too) and invite all of you to compete. Round will have $$$5$$$ or $$$6$$$ tasks and lasts $$$3$$$ hours. Tasks will be slightly harder than usual CF Div 2 round.

All task are prepared by ICPC team RAF Penguins: Pajaraja, milisav and allllekssssa.

Also I would like to thank DuX and all other students from my faculty for maintenance the platform.

As some labels on the site are in Serbian, everything that you need to know for doing contest is the following:

After registration on the site you need this link for the round (currently round is in upcoming part). In the moment when round starts you can join — there is no extra registration for the round. English statements will be in a visible place.

See you on Sunday!

UPD 1: Scoring for the round: $$$30 - 50 - 70 - 80 - 120 - 140$$$

English versions of statements will be at the top of each problem. As I didn't mention before, scoring system is same as AtCoder system with full feedback, only you are getting $$$10$$$ minutes for wrong submission.

UPD 1: Contest starts in $$$30$$$ minutes.
