Microsoft Development Center Serbia is thrilled to announce the finals of the 14th edition of Bubble Cup competition! Bubble Cup is an international, ICPC-style team contest aimed at university and high school students.
Just like the previous editions, this final will be followed by an online mirror competition on Codeforces. Mirror will take place on the same day about an hour after the start of the finals — Oct/09/2021 12:05 (Moscow time). Contest will last for 4 hours and ICPC rules will be applied. It will be a competition for teams of 1-3 members. There will be at least eight problems.
Just like last year, the finals are divided in two "divisions", called Premier League and Rising Stars. The two contests will have most of their problems in common, but the Rising Stars competition will feature some easier tasks targeted at high school contestants.
Both of the contests will be mirrored here on Codeforces, with Premier League mapping to the Div1 contest and Rising Stars mapping to the Div2 contest. The mirror will use native Codeforces ICPC team contest rules. Each team is allowed to use multiple computers.
Both contests will be unrated, due to the format and the length of the mirror being dissimilar to the standard Codeforces rated rounds.
The problems and their solutions were created by employees and interns of Microsoft Development Center Serbia: niksmiljkovic, acac97, renea, BubbleCup, nikolapesic2802, berke00, davidmilicevic97, ijevtic, dj0l3, igzi, Kole, Vasiljko, pavlej and me TadijaSebez.
We give our thanks to Nikolay Kalinin (KAN) and Mike Mirzayanov (MikeMirzayanov) for making these mirror contests possible and for the wonderful Codeforces and Polygon platforms. Special thanks goes to Alexandr Lyashko (knightL) for helping out with problem testing.

We wish good luck to all participants!
