It offers a unique, pattern-based approach to mastering technical interview questions, making it an invaluable resource for anyone preparing for software engineering interviews. Instead of randomly tackling problems, this repository groups questions under specific subtopics, allowing users to focus on repeatedly applying common patterns and solidifying their understanding of fundamental data structures and algorithms. The full question list is available on a dedicated website.\n\n## Installation\n\nTo get started with the Leetcode Patterns project locally, follow these steps. The application is built with Next.js (App Router), React 19, TypeScript, Tailwind CSS v4, TanStack Table v8, and Lucide React for icons.\n\nFirst, clone the repository and install the dependencies:\n\nbash\nnpm install\n\n\nThen, you can run the development server:\n\nbash\nnpm run dev\n\n\nThis will start the application at `http://localhost:3000`.\n\nFor testing, you can use:\n\nbash\nnpm test            # single run\nnpm run test:watch  # watch mode\n\n\nA Husky `pre-push` hook is configured to run `npm test` automatically before every push, ensuring code quality.\n\n## Examples\n\nThe core of Leetcode Patterns is its curated list of questions, organized by common patterns. You can access the entire question list directly on the project's website:\n\n[Leetcode Patterns Question List](https://seanprashad.com/leetcode-patterns/)\n\nSolutions, primarily written in Java, are available in a dedicated branch within the GitHub repository:\n\n[Solutions Branch (Java)](https://github.com/SeanPrashad/leetcode-patterns/tree/solutions)\n\nThe repository also emphasizes the importance of understanding fundamental data structures like Arrays, Maps, Linked Lists, Queues, Heaps, Stacks, Trees, and Graphs, along with algorithms such as Breadth-first search, Depth-first search, Binary search, and Recursion.\n\n## Why Use Leetcode Patterns?\n\nLeetcode Patterns stands out due to its systematic and focused approach to interview preparation. By categorizing problems by underlying patterns, it helps you build a strong intuition for problem-solving, rather than just memorizing solutions. This method is highly effective for:\n\n*   **Structured Learning**: Move beyond random problem-solving to a guided, pattern-focused study.\n*   **Skill Reinforcement**: Repeatedly apply common algorithms and data structures within similar problem contexts.\n*   **Interview Readiness**: Directly target the types of questions frequently encountered in technical interviews.\n\nThe project draws inspiration from renowned resources like \"Grokking the Coding Interview,\" the \"Blind 75 list,\" and articles on common coding interview patterns, ensuring a comprehensive and effective study guide.\n\n## Links\n\n*   **GitHub Repository**: [https://github.com/seanprashad/leetcode-patterns](https://github.com/seanprashad/leetcode-patterns)\n*   **Live Question List**: [https://seanprashad.com/leetcode-patterns/](https://seanprashad.com/leetcode-patterns/)\n*   **Solutions Branch**: [https://github.com/SeanPrashad/leetcode-patterns/tree/solutions](https://github.com/SeanPrashad/leetcode-patterns/tree/solutions)","metrics":{"detailViews":3,"githubClicks":1},"dates":{"published":null,"modified":"2026-07-17T23:48:52.000Z"}}
