🚀 DSA Practice – LeetCode (Python)

This repository contains my solutions to Data Structures & Algorithms (DSA) problems from LeetCode, implemented in Python.

📘 Python DSA Handbook

I’ve created a beginner-friendly Python handbook to make starting LeetCode less intimidating. It covers:

• Python basics (for absolute beginners)
• Built-in functions used in DSA
• Important problem-solving patterns

📘 Handbook: LEET Handbook.pdf

This handbook is meant to be a comfort guide — not a shortcut.

🧩 Problem Solving Approach

• Focus on understanding patterns
• Start with Easy problems
• Prioritize clarity over speed
• Revisit mistakes and learn from them

🎯 Goal

Build strong DSA fundamentals using Python and stay consistent with practice.
