Refactor one thing

[dpshelio]

Continuing with the example you reviewed before and the discussion you had (issues #45, #46, #47). Let's implement at least one improvement.

1. First, take around 5 minutes to plan your changes.
2. Once that is done, start making changes according to your plan.

To get the files on your computer and push them back, remember to:

1. Fork the repository
2. Clone your fork
3. (create branch, make changes, commit...)
4. Push back to your fork

You can submit a Pull Request for the original repository when you have made some change.

• You don't have to wait until they're all done!
• Target the main branch of the original repository
• Indicate the example you have worked on in the title of the PR, e.g., "Boids: rename variables"
• Link your PR to this issue adding Answers UCL-COMP0233-23-24/RSE-Classwork#48
• If you have more time, add more commits to your branch so they are included in the pull request (update the title accordingly if needed)
