🚀 LeetCode Solutions in C++

Welcome to my collection of LeetCode problem solutions written in C++, organized simply by question number for quick access and clarity.

This repository is my personal archive to track progress, revise daily, and help others who are practicing for coding interviews and competitive programming.

👨‍💻 About the Repository

  • 🟦 Solutions are named using the LeetCode problem number, like 1.cpp, 42.cpp, etc.
  • 🔢 Covers a wide range of topics including arrays, linked lists, trees, DP, backtracking, and more.
  • ⏱ Most questions are solved using optimal or near-optimal time/space complexity.
  • 📘 Written using clean, readable, and beginner-friendly C++ code.

📌 Sample File Naming

Here’s how solutions are named:

  1. LC_1.cpp //Two Sum
  2. LC_2.cpp //Add Two Numbers

You can search the LeetCode website using the question number to match it with the solution.

✅ Why Use This Repo?

  • 📚 Revise core DSA concepts and common patterns (e.g., sliding window, two pointers, recursion).
  • 🧠 Great reference during interviews and contests.
  • 🤝 Helpful for students, job seekers, and those practicing consistently on LeetCode.
  • ✨ All code is hand-written, well-tested, and explained with comments wherever needed.

🧠 Recommendations for Practicing

  • Start with easy/medium questions by topic (e.g., Arrays, Strings, Linked Lists).
  • Focus on patterns like Binary Search, Heap, Backtracking, DP, etc.
  • Try solving problems yourself first, then refer to solutions here as needed.

🏁 Getting Started

  1. Clone the repo:

    # Clone the main repository from the parent directory
git clone https://github.com/your-username/your-new-repo-name.git

  2. Open any .cpp file using your preferred C++ IDE (VS Code, CodeBlocks, etc.)

  3. Run and test locally, or copy into an online IDE like LeetCode Playground or OnlineGDB.
