🧠 LeetCode Solutions

Welcome! Here I collect my solutions to problems from LeetCode — with descriptions, difficulty levels, and approaches to solving them.

📌 Structure

Each problem is represented as a separate file and includes:

• 📄 Problem description
• ⚙️ Difficulty — Easy, Medium, Hard
• 🧮 Solution - Python, SQL
• 📈 Asymptotic complexity — Time complexity, Space complexity
• 💡 Additional details — brief explanation, approach, optimization (multiple solutions from simple to advanced)

In addition, there is a 📁 code_templates folder with reusable patterns for solving common types of problems, such as:

• 🔍 binary_search
• 🧩 backtracking
• 🌳 binary_tree
• 🌐 graph
• ...and more
