It proposed to create an web platform on which students to upload their solutions at problems of Data Structures and Algorithms.

As technologies, it uses:

• Python for evaluating and compiling the solutions
• GCC as the compiler for C/C++ code
• Subprocesses to run the compilation routine
• Apache, MySQL, PHP and Laravel for backend of the server
• Using Laravel, it must build based on OOP and MVC principles
• Fronted was made using HTML, CSS and static React (Gatsby) to generate the webpages
• For CI pipeline and DevOps maintaining we used Docker containers

To make it extensible, we implemented a plugin/theme extension for Laravel, but it can use RESTful APIs if it is a must. To hook a plugin/theme, the app folder hosts all the plugins/theme files and it must be registered as class in plugins.php. Theme files are saved on the database and they are requested on home root when necessary.
