Hello everyone, we are happy to announce that the 1st Universal Cup is started officially.

Universal Cup is a non-profit organization dedicated to providing training for competitive programming teams. Our website is https://ucup.ac/ (in English and Chinese).

In recent years, Chinese problem-setter teams have created a great number of high-quality contests. We have reached an agreement with most of these setters, that they agree to provide contest materials to Universal Cup for hosting mirror contests before publishing the set in public. We believe that such an arrangement can provide good opportunities to teams who want to do better in the future competing.

Every year, with the permission of the problem setter team and without involving copyright disputes, the Universal Cup will hold mirror contests for some undisclosed competition sets. It is expected to hold at least 10 contests a year. We will simulate the actual situation in the competition, using the DOMjudge platform and executing the board freeze in the last hour. At the same time, we will provide an overall rating board, which will help the team to make a reasonable assessment of itself.

In the 1st Universal Cup, with the support of multiple problem-setting teams, it is expected to include at least 6 undisclosed ICPC/CCPC contests and 4 provincial collegiate contests. We are also inviting outstanding teams and players from all over the world to participate in the competition as well as helping us to promote Universal Cup. At the same time, we are also contacting various problem-setting teams to discuss cooperation matters. It is very welcome that any team would like to provide their sets.

We expect to host the mirror contest on some Saturdays. To resolve the timezone issue, we plan on hosting three time windows:

  • 13:00 — 18:00 (UTC+8) on Saturday
  • 19:00 — 24:00 (UTC+8) on Saturday
  • 02:00 — 07:00 (UTC+8) on Sunday

There will be an independent scoreboard combining all previous results during each time window.

The first contest will be the 2022-2023 ICPC Shenyang Regional on January 28th. The second contest will be the 2022-2023 ICPC Hong Kong Regional on February 4th. The upcoming contests will be announced on the official website.

We require registration to participate in the Universal Cup, please follow the instruction on the official website.

I started using TopCoder Web Arena to upsolve older SRMs, since moving to a new practice room takes too long while using Java Applet (could be my Internet issue).

Here's the problem. Large integers (about $$$10^{16}$$$) can't be shown correctly in the Web Arena.

Example:

And as you can see, the verdict shows N/A instead of Correct or Wrong Answer. It's very weird.

Be aware of this hmehta.
