### Learning Objectives

- [ ] Practice applying concepts related to the sprint's prep material in a kata.
- [ ] Problem solve a new coding challenge.

### Why are we doing this?

Every week, you need to complete all of the katas in the collection. If you have completed the mandatory katas for Data Groups Sprint 1, you can try these stretch katas.

Spend at least 20 minutes per kata.

Find the Collection called "CYF Data Groups | Sprint 1 | Stretch" on [the CodeYourFuture account](https://www.codewars.com/users/CodeYourFuture/authored_collections).

Check your Codewars completion status via the [Codewars Progress Checker](https://codeyourfuture.github.io/Codewars-Progress-Checker/).
