Hello Codeforces!I have prepared a complete, beginner-friendly problem set designed specifically for a Div. 4 round.Crucially, the entire package is already finished in Polygon — all tasks have validators, generators, and initial test sets ready. I am fairly confident that most of the problems will pass review without any issues.However, I don't know whom to officially send this Div. 4 set to, and due to a very tight personal schedule, I will not have the time to make technical revisions or handle potential test failures during the review process. Furthermore, I currently don't have a co-author who could come up with and add backup problems in case a task gets rejected due to an accidental duplicate (overlapping ideas with past contests).Because of this, I am looking for a co-author / partner to take over the project.What is already done:100% complete problem concepts, statements, and balancing for Div. 4.Fully working Polygon packages (generators, validators, checkers, main solutions).What is expected from a co-author:Handle any required fixes, edge-case testing, or minor rewrites in Polygon if the testing team requests changes.Bring or come up with a few backup problems to safeguard the round in case of any issues.Since the heavy lifting of writing Polygon scripts from scratch is completely done, this should be a very straightforward and smooth process for someone who has the time to manage the technical feedback loop.Please PM me directly here on Codeforces if you are interested in co-authoring this round!
