Hello Codeforces! The 8th Stage of the 1st Universal Cup is coming. It will be held from Mar 18th to 19th.

The contest is based on an official ICPC European regional contest. It has been used in the 2022 ICPC Central Europe Regional Programming Contest, which was held on November 25, 2022 — November 27, 2022 in Ljubljana, Slovenia. Please, don't participate if you are already familiar with the problem set.

Thanks to the authors of the problem set: thocevar, koci, jureslak, jklepec, nbasic, MKoding and others.

As usual, there are three time windows in which you can participate in the contest:

• Mar 18th 13:00 — 18:00 (UTC +8)
• Mar 18th 19:00 — 24:00 (UTC +8)
• Mar 19th 02:00 — 07:00 (UTC +8)

Please note that you can see two scoreboards in DOMjudge. The 'Local Scoreboard' shows the standings ONLY IN THE CURRENT TIME WINDOW. And the 'Combined Scoreboard' shows all participants, including the onsite participants, and the cup participants in the previous time windows.

Central European Olympiad in Informatics 2017 will this year take place in Ljubljana, Slovenia from July 10 to July 15. I would like to invite you to an online contest featuring the CEOI task which we'll organize after the conclusion of the on-site contest.

The online contest will last 5 hours and feature 9 problems from the practice session and both competition days. It starts on Saturday, 15 July at 14.00 CEST (UTC +2). Registration will be enabled after the conclusion of the on-site contest on Friday.

The contest will be suitable for a wide range of contestants with the typical divison of problems into subtasks. With a relatively narrow time frame of 5 hours it should present a challenge even to the best. We're looking forward to your participation.

UPDATE 1: The onsite contest has concluded. You can check the results.

UPDATE 2: Registration on the online judge is now open. Good luck tomorrow.

UPDATE 3: Congratulations to demon1999 for winning the online contest and thanks to everyone who participated. We will upload the tasks, tests and solutions to the web page shortly.

The Gym contains a nice set of NEERC contests, which are a valuable learning resource. After spending 5 hours on a problem set you learn where are your problem solving limits. But to move beyond those limits, you need some help in form of solution outlines.

European regionals usually post solution presentations on official websites, but I can't find them for the NEERC regional and subregional contests. I don't speak Russian, which makes looking for them even harder. This site has a large archive of final standings but only a few solution presentations. Does anyone know where to find the rest? Google translate works well enough so it's not a problem if they are in Russian. How about attaching the solutions to the gym so you don't have to go looking for them elsewhere? If they are not already available, whoever sets up a gym contest could add their own.
