Hello Codeforces

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 interesting and helpful.
