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.
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!
27 wrz 2020 · Problem. Given an array of \ (n\) integers, you should print any prime number in the array. It’s guaranteed that the array contain at least one prime number. Constraints: \ (1 \le n \le 10^3\), \ (1 \le A_i \le 10^3\). Create the problem.
Recently someone asked for a tutorial about using polygon to prepare problems, I couldn't find such tutorial so I decided to write one. 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 ...
*has extra registration. → Streams Atcoder ABC #362 Solution Discussion
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;
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
