A curated collection of clean, optimal, and multi-language solutions to LeetCode algorithmic and database problems.
Track my problem-solving activity, ranking, and contest progress directly on LeetCode:
- Multi-Language Solutions: Problems are implemented across Python, TypeScript, JavaScript, Java, and SQL.
- Clean & Optimal: Focus on readability, optimal time/space complexity, and modern syntax.
- Reference Headers: Solutions include problem titles and links back to the original LeetCode challenge.
Solutions are organized into modular range folders to keep the repository structured and scalable as more solutions are added:
Leetcode-Solutions/
└── <range_folder>/
└── <problem_id> - <Problem Title>.<ext>
- Range Folders: Group problems into convenient batches (e.g.,
3851-3900/,0151-0200/). - File Naming:
<problem_id> - <Problem Title>.<ext>containing the solution along with problem links and notes.
