In this test, you'll need to prove your problem solving skills worth.
The repo contains a spec file, which will test your code against the expected result.
The problem you need to solve is the next one:
Remember to create your branch and upload your results there. Do NOT upload directly to master.
If you want to test your logic against the automatic test, install all dependencies with
npm install
Then run the test suite
npm test
Good luck! :D
