Hello,

Our training contest in Xidian University, named 2020-2021 “Orz Panda” Cup Programming Contest will start on Nov. 22, 2020.

The problems are prepared by Xi Ruoyao (me, loujunjie) and Wang Xiaoqing (qkoqhh). Thanks Huang Haitong (fffasttime) for testing the problems. And thanks MikeMirzayanov for Polygon and Codeforces.

The online mirror will start at Nov/22/2020 09:00 (Moscow time), one hour after the onsite training contest starts. Unfortunately I can't make the mirror public now, because some participant of the onsite round has Codeforces coach rights (for example flukehn). I will make it public after the onsite round starts.

We will select ICPC regional teams from the candidates in Xidian University, by the ranking of this training contest. The problems are easier than ICPC regionals though we tried to make them regional-like.

The training round is for teams, but both teams and individuals can take part in the online mirror.

The “Orz Panda” is a lovely figure we often use to show respect to others.

If you decide to take part in, thanks for support. If not, thanks for reading my bad English.

UPD1: Congratulations to team Symplectic Geometric Rhythm (flukehn, bzy, and danihao123), who won the contest with 7 problems solved! The ghosts and tutorial will be uploaded soon.

UPD2： The ghosts and tutorial have been uploaded.

Hello,

Our training round in Xidian University, named The 2019 “Orz Panda” Cup Programming Contest will start on Aug 20, 2019. There are some people who wish to participate in the round but they can not reach the campus at time. So as the contest manager I decide to mirror the round on Codeforces.

The problem set is prepared by Xi Ruoyao (me, loujunjie). Thanks Jing Linxiao (jl0x62) and Liu Sen (ls961006) for testing the round. Thanks Wei Yanming (wym6912) for providing IT support for the round. And thanks MikeMirzayanov for Polygon and Codeforces.

The online mirror will start at Aug/20/2019 11:00 (Moscow time), one hour after the onsite round starts. Unfortunately I can't make the mirror public now, because some participant of the onsite round has Codeforces coach rights (for example wang9897 and qkoqhh).

Most participants of the “Orz Panda” Cup are new candidates for our ICPC regional team. So the round is prepared to be relatively easy. The difficulty is like a Div. 2 (in my opinion) so it may be boring for experienced ones.

The training round is for the team but both teams and individuals can take part in the online mirror.

The “Orz Panda” is a lovely figure we often use to show respect to others.

If you decide to take part in, thanks for support. If not, thanks for reading my bad English.

UPD1: Because the training round is delayed for 40 minutes, unfortunately, we have to delay the mirror for 1 hour.

UPD2: There was an issue in the statement of problem I. The statement has been updated. Sorry again for the issue.

UPD3: The round is finished. I'll finish up the editorial (and including some solution better than mine, from the team Geometric Rhythm including wang9897, qkoqhh, and fffasttime), then publish it.

UPD4: The editorial is now available.

UPD5: The ghost participants have been added.
