🚀 LeetCode Journey

Algorithms | Data Structures | Problem Solving

A personal journal of my path to mastering algorithms, writing efficient code, and implementing CI/CD automation.

---

📖 Overview

Welcome to my personal collection of LeetCode solutions. This repository is not just a code archive, but an active workspace where I develop my problem-solving skills, analyze complexities, and apply software engineering best practices.

The progress tracking and solution tables are automatically generated and updated via a custom GitHub Actions CI/CD pipeline, turning this repository into a fully automated project.

🎯 Core Goals

The main goal is not just "passing the tests," but writing code that is:

• ⚡ Efficient: Strong focus on Time Complexity (Big O) and Space Complexity analysis.
• 📖 Readable: Clean, "Pythonic," and well-commented code following PEP 8 guidelines.
• 🛡️ Robust: Proper handling of edge cases, memory safety, and logical structuring.
