This small project uses FastAPI. To run it, use Python 3.9 (3.10 should work too). Python 3.9+ is required because of the @cache decorator.
After creating a virtualenv or setting up Python3.9 the way you prefer, do pip install -r requirements.txt, which will install FastAPI, Uvicorn, and Pytest.
To run the server, do uvicorn main:app --reload, which will run the project on port 8000 by default.
The endpoints are:
/special-math/{number}/special-math/{number}/no-recursion
The first runs the function with the @cache decorator and does recursion. The second, as the name imples, uses a non-recursive solution, and can therefore accept larger numbers.
To run the tests, just do pytest.
