Polygon.Codeforces Tutorial - A Guide to Problem Preparation [Part 1] 08 Mar 2022. This is the first part of my series on problem preparation for a programming contest. In this part, we are going to familiarize ourselves with Polygon -- a modern platform for this purpose in a professional way!
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.
27 wrz 2020 · Checker should read the contents of the input, output and answer, decide whether participant answer is correct (and optimal being compared to the jury’s answer if there can be unoptimal answer in this task) and return one of several pre-defined verdicts.

I will present two algorithms for each problem: one for arbitrary simple polygon, and one for strictly convex polygon, that has better complexity. The priorities in implementation design were as follows: handle all the corner cases, except for degenerate polygons with zero area; perform all computations in integers;
You can find the tutorial here. This tutorial is beginner friendly, I tried to explain every step in details and through the tutorial I have created a complete simple problem. I hope you will find this tutorial interesting and helpful.
The mission of Polygon is to provide platform for creation of programming contest problems. Polygon supports the whole development cycle: problem statement writing; test data preparing (generators supported) model solutions (including correct and wittingly incorrect) judging; automatic validation
