A Warrior's Chronicle of Data Structures & Algorithms

⌨️ Written in blood, sweat, and pure C++ ⌨️

🔥 The Manifesto

"Every array reversed, every tree traversed, every DP table filled — is one step closer to the offer letter."

This repository is not just code. It's a battle log. Every file here is a boss fight I've defeated on my road to becoming an AI/ML Engineer at Google. No shortcuts. No copy-pasted solutions. Just raw problem-solving, one .cpp file at a time.

🧠 Why This Repo Exists

while (!goal.achieved()) {
    solve(oneMoreProblem());
    commit("Slightly better than yesterday");
    push();
}
// goal.achieved() == "AI/ML Engineer @ Google"

I'm currently pursuing a BS in Data Science & Applications (IIT Madras) alongside a BSc in Physical Education & CS (DDU College, Delhi University) — and this repo is where I sharpen my problem-solving blade daily on LeetCode, one commit at a time.
