I do coding problems sometimes - I've decided to dump mine in this repository so I can look at them later if I need and example of how to do something that I know I understand.
Each directory has a slightly different structure
exercism is problems from exercism.io
Exercism is great, it has a command line tool which neatly downloads the tests and readmes into a folder. As such - the folder structure is better.

└── language
└── task

tl is problems from techseries.dev
These are copied and pasted from somewhere I don't quite remember. I don't tend to do these often.
└── problem
├── README.md
└── main.lang
codewars is problems from codewars.com
These are copied and pasted from the website. This is more of a dumping
ground. Each solution contains a link to the kata. kyu is a measure
of difficulty used by the site. Smaller number is harder.

Exercism is a clear favourite for me.
