Online Judge

by Shubham Goyal22/1/2022


Online-Judge is a small replication of platform like SPOJ. Where a piece of code is submitted against a pre existing question. The platform will run the submission against various test cases to decide whether the submission is accepted or not.

This year in Foss Overflow 2021, I have worked on Online Judge project. It is a backend system to run and check submitted code


I achieved a lot of things during this project, some of them are:

  1. Create a submit code API.
    • The API will take a piece of python code to run against a question.
  2. Run submitted code in background
    • The code are submitted and run in the background. This frees up the API for further use.
  3. Predefined Questions and Test
    • Currently, we have some predefined questions and tests. Against which a submission can be submitted
  4. Code submission status API:
    • Any code submitted will be allotted some id. Status of a code any time can be checked. The status can be Accepted, Wrong Answer, Run time error

and much more...


I have been working on this project a lot since the start and I am happy with the results. We managed to achieve what we had hoped for the backend part. It was a great experience for me. I met many new people and learned a lot through this project. I am glad to be a part of this project.
