ashmsd7/DataStructures-Algorithms ? reverse-engineered prompt

Build me a clean Python study repo for data structures and algorithms, with one folder per problem and a simple place to keep my notes as I go.

I want it organized around common coding challenge questions, where each problem folder has the solution code and a short explanation of the approach, time complexity, and any tricky edge cases. Make it easy to add new problems over time, and keep the structure consistent so I can quickly find things later.

Please set it up so the repo feels like a personal progress tracker too, not just a dump of answers. A simple top level overview would be great, along with a clear way to see which problems are done and what category they belong to, like arrays, linked lists, trees, strings, and dynamic programming.

Keep the code readable and beginner friendly, and if you need to check current Python conventions or docs online, go ahead.
