### 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 extra time, you can do extra katas at random on CodeWars.

Spend at least 20 minutes per kata, find time at least three times a week to complete this.

Find the Collection called "CYF Data Groups | Sprint 3 | Mandatory" 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/).
