Auto-Submission Script for Ejudge

This project contains a Python script that automates the process of submitting solutions to the Ejudge online platform, adding test cases to a C++ solution, and re-submitting until successful.

---

Features

1. Automated Run ID Retrieval: The script fetches the latest run_id from the Ejudge page.
2. Dynamic Test Case Extraction: Extracts the last test case's input and correct output from the Ejudge submission page.
3. Test Case Insertion: Dynamically adds new test cases to a provided C++ solution file.
4. Solution Submission: Automatically submits the modified solution back to Ejudge.
5. Error Handling: Handles missing test case sections and ensures robust interaction with the Ejudge platform.

#How to Use Clone the repository and navigate to the directory:

Копировать код
git clone https://github.com/monlaf-sfk/ejudge_generator.git
cd ejudge_generator

Set the required constants in the script.py file:

• URL: Base URL of the Ejudge platform.
• SID: Ejudge session ID.
• PROB_ID: Problem ID to submit the solution for.
• FILE_PATH: Path to the C++ solution file. Run the script:

python main.py

The script will:

Fetch the latest run_id. Extract and add test cases to solution.cpp. Resubmit the modified solution. Key Functions add_test_case_to_cpp(cpp_file_path, test_input, correct_output) Adds new test cases to the specified C++ file.

fetch_run_id() Retrieves the latest run_id from Ejudge.

submit_solution(run_id) Submits the solution and handles the process of extracting and injecting test cases.

main() Orchestrates the overall workflow.

Future Improvements

Add support for multiple languages (not just C++). Implement retry logic for failed submissions. Enhance logging for better debugging. License This project is open-source and available under the MIT License. Feel free to use and modify as needed.
