Contains Questions from Tier 1 to Tier 3.

Every folder has instructions for the challenge and a test suite.

To run the test suite, Node.js needs to be installed. After, just run npm install in the root directory (where the package.json file is located) and you can run npm run test. If you want to run a single test suite instead of all of them, you can go to the directory and run npm run test -- <test-file-name>.test.js.

Please refer back to the Google Doc that was shared with you for further instructions on how to submit.
