Ah! You've travelled far ny friend. Hope you don't mind some tea? My name is Ilori Stephen and I am a software engineer who's created this resource to help you understand some concepts around data structures.
This repository is divided into several folders and possibly sub-folders representing different data structures. I forgot to mention that the most of the solution is written in typescript. However, if you are interested in writing or converting this to other languaged to help others, please, send in a pull request.(and your tea is getting cold).
