My team and I created the IUPC 2025 contest for Northern University of Business and Technology Khulna (NUBTK). The contest is now live on Codeforces Gym.
The development and problem-setting process were managed through the following repositories:
Step 1: Create a Codeforces Polygon Account
First we need to create a account in codeforces polygon. Then we have to create a polygon account. After registration we need to login in polygon account. After login we will see a profile page like this. Now we can create a New Problem.
Step 2: Create a New Problem and set general information
Name the problem using lowercase letters and no spaces. In the general information section, you must specify the input file, output file, time limit, and memory limit. If the problem is interactive, mark the interactive checkbox, add the problem tags, and then save the information. You can also add a contest name and a tutorial sketch if needed.
Step 3: Set the problem statement
In the Statement section, you define the core of your problem using LaTeX. This includes the Name, Legend, Input format, and Output format. You can also include a Tutorial, and Notes if needed.
- LaTeX Guide: Polygon provides a brief manual; however, note that standard LaTeX and Codeforces LaTeX have some differences.
- Images: To include images in the statement, upload them to the Statement Resource Files section and follow the syntax provided in the manual.
- Preview & Export: You can edit and preview your statement in the Edit and Preview section, or view it in the In HTML and In PDF sections.
