🚀 Striver A2Z DSA Sheet – Complete Solutions 💻❤️

Welcome to my journey through the legendary Striver A2Z DSA Sheet!
This repo is my personal notebook of code, struggle, late-night debugging, and tiny victories — all in the name of mastering Data Structures and Algorithms.

🌟 About the Sheet

The Striver A2Z DSA Sheet is one of the most comprehensive DSA roadmaps out there — carefully crafted by Striver (Raj Vikramaditya) to guide you from absolute basics to advanced problem-solving.

Whether you're preparing for placements, internships, or just want to build your fundamentals like a boss, this sheet is a total game-changer.

📁 Structure of this Repository

This repo contains:

✅ Clean code for every question in the sheet.
🧠 Problem links (mostly from Leetcode, GFG,Coding Ninjas or CodeStudio).
📌 My insights & observations when something tricky shows up.

Each section of the sheet (Basics, Arrays, Sorting, Recursion, DP, Trees, Graphs, and more) has its code and built with 💙.

📅 Current Progress

This journey is ongoing. I’m committed to consistency.
Some days are easy, some days are brutal — but every line of code is a step closer to cracking it.

Keep an eye on this space — updates coming in regularly! 🛠️

🧑‍💻 Why I'm Doing This

Honestly?

To build real DSA muscle.
To stay accountable and consistent.
To help others walking the same path.
And yeah… maybe crack a few FAANG dreams on the way ✨
