Taken Decisions

• I chose to use Python because it is a language that I'm confortable with.
• I didn't use any framework because it is a simple project, and a framework would generate a lot of boilerplate code.
• I didn't put the token directly in the code because I didn't want to make it public for a matter of security.

Note: To understand the code easily, you can follow from line 97.

Complexity

• The total time complexity is: O(n) + O(n x m_log_m) + O(n x m) = O(n x m_log_m), where n is the number of users and m is the number of activities for each user

How to run the code

Running locally

• Install Python if you don't have it already.
• Go to the project's directory and run the following command:
  • pip install -r requirements.txt
• Add a environment variable called API_TOKEN with the API's token.
  • If you don't know how to do that, simply run: API_TOKEN=<token> python3 main.py
• Run: python main.py (or python3 main.py)

Using Docker

If for some weird reason you don't have a python interpreter, but do have Docker installed, you can run this code through it. Run the following commands:

• docker build -t testslang .
• docker run -e API_TOKEN=<token> -it testslang, where <token> is the API's token.
