LeetCode Problem Solutions

This repository contains my solutions to various LeetCode problems that I solve during my practice sessions.

📚 About

  • ✍️ Each file corresponds to a single LeetCode problem solution.
  • 📄 Solutions are uploaded as I solve them — no strict folder structure.
  • 🧠 Focused on improving problem-solving skills and algorithmic thinking.

🛠️ Languages Used

  • Python (mainly)
  • (Other languages may be added over time)

🚀 How to Use

  1. Clone the repository: 
    git clone https://github.com/Minhaj401/Leetcode.git

Browse through the files.

Each file is typically named after the problem title.

🌟 Notes

  • Solutions are self-written unless otherwise mentioned.
  • Some problems might include multiple approaches inside the same file.
  • Code is tested against LeetCode test cases.
  • If a solution isn't optimal, feel free to open a discussion or issue!
