Online Judge (Online code evaluation system)

All project files added in branch master. Project information shown here:

Overview

This project is an Online Judge system built using Django. It allows users to register, login, browse programming problems, submit solutions, and receive automated feedback on their submissions. The project consists of three main applications:

1. accounts - Handles user authentication and profile management.
2. home - Manages problem statements, test cases, and submitted solutions.
3. compiler - Compiles the code and checks if the problem submitted is correct or incorrect using the testcases.

Features

• User Authentication: Registration, login, logout management.
• Problem Management: View programming problems.
• Submission Management: Submit solutions, view submission status, and results.

Technologies Used

• Django: Web framework for the backend.
• SQLite: Default database for development (can be switched to PostgreSQL/MySQL for production).
• HTML/CSS: Frontend technologies for creating responsive and interactive UIs.
• Bootstrap: Frontend framework for styling.
