LeetCode

A personal collection of LeetCode problem solutions with clear problem statements, well-tested code, and detailed design documentation.

Each problem lives in its own folder and contains everything needed to understand, run, and review the solution.

What’s Inside Each Problem Folder

File	Purpose
README.md	Official problem statement, examples, constraints, and link to LeetCode
src	Clean, production-quality implementation with unit tests
design-doc.md	Solution explanation, time/space complexity, why this approach was chosen, alternatives considered, and any interview notes

Goals

• Clarity – Every solution is explained thoroughly so it can be revisited months later.
• Correctness – Solutions are backed by automated tests.
• Interview readiness – Design docs capture the reasoning and trade-offs you would discuss in an interview.
• Consistency – Uniform structure across all problems makes navigation easy.

How to Use

1. Browse by problem number or title.
2. Read the problem README.md first.
3. Review the design-doc.md for the thought process.
4. Look at the code and run the tests if desired.
