It aims to introduce the Polygon platform to the new problem setters, and guide them through the basic steps on creating a new problem from scratch. In the post, I have explained the concepts and practices that a problem setter need to know in order to use Polygon to prepare problems.
Download "contest.xml" file from the contest page by clicking the Download Descriptor link. If you use Download package link, you can also find a file named "contest.xml" in the package. However, problems in this file are indexed by lowercase letters whereas Codeforces needs uppercase letters.
As an allowed language on Codeforces and Polygon C++17 has been added. The compiler we use is 32-bit mingw64 version 7.2.0 (later will be updated when new versions are released). We are using a patch from h alyavin to speed up I/O when using scanf/printf (for more details, read here).
Polygon is a service to prepares programming problems and contests. It is usually used to prepare problems for olympiads/programming contests but it is also often used to prepare educational content. It is located at https://polygon.codeforces.com/ and is open to everybody. Here are three recent new features:
A guide for creating Codeforces problems on Polygon. The problem creator generates test case inputs using a test case script, generator, and (optional) validator. When a contest participant submits his or her solution, a checker can be used to verify if their program's output has valid syntax.
