I started to learn Backend and before i was interested to competetive programming. So i wondered how actually Leetcode works under the hood, how they actually check submissions? So i started to explore, and came up with idea by myself of creating isolated container with 128mb ram and running there N testcases and deleting the container.

In result, this is my project that i did. Its roughly MVP only for local stuff. Im lazy for making documentation for cloning the repo properly and etc, i dont remember even did i do the docker compose or not, it just works
