VineetLoyer/LeetcodeGrind ? reverse-engineered prompt

Build me a clean Python LeetCode practice repo like a grind journal, with one folder per problem and a working solution in each folder.

I want it organized by problem number and title, like 0001 two sum, 0003 longest substring without repeating characters, and so on, so it’s easy to browse and add new problems later. Keep the solutions simple and readable, with the usual LeetCode style, and make the main README act like an index of all the problems grouped by topic or category.

If it helps, you can also add a small stats file or summary so I can see what’s already done. Focus on making it tidy, consistent, and easy to extend as I keep adding more coding practice problems. If you need to check current best practices for README formatting or Python project structure, look them up online.
