feat: Implement Run Service

[georgetayqy]

Description

We do not have a sandboxed environment where we can execute code right now.

We can integrate Judge0 into our application to ensure that users are able to execute code on the server.

An instance of Judge0 has been deployed onto AWS, and I have shared the IP address privately with you to prevent abuse of the system right now.

Remember to include the API Key with the Headers X-Auth-User and X-Auth-Token to ensure that you are authorized to make calls to the /submissions path on the sandbox to execute your code.

The Schemas for the inputs and outputs have been added into the team's Miro board, but I have included them below for your convenience:

Request

{
  "source_code": "string",
  "language_id": "71", (for Python)
  "stdin": "string",
  "expected_output": "string", (w.r.t stdout, users need to print their answers ~ Kattis)
  "max_processes_and_or_threads": 1,
  ["cpu_time_limit": 10.0 (in seconds)],
  ["cpu_extra_time": 1.0 (in seconds)],
  ["memory_limit": 12800 (in KB)]
}

Note

The [] values represent optional values you may or may not want to set. Defaults have already been set on the server.

Response

 "stdout": null, (or string)
  "time": "0.02", [in seconds]
