This project is a collection of code samples and wiki articles on basic data structures and algorithms that are created using Kotlin. This project is useful if you are trying to get more fluency in Kotlin or need a refresher to do interview prep for software engineering roles.
developerlife.com has a set of tutorials that are based on the code that's provided in this repo. I would recommend you check these tutorials out as a way to get a handle on what the code in this repo does.
