# Exercise - The Match Case
First off - the goal is not to have a working solution (as soon as possible), but to show how you would tackle a technical problem.
As such:
- Describe in your own words the problem is
- Which steps you would take in order to solve it
- Take these steps to work out the algorithm, pseudo-code or actual :)
- Explain how it works, and why it works
After that:
- Given some edge-cases, explain why it does not work (if applicable)
- Work out & explain how to solve for these edge-cases as well
