🚀 Alpha - Java Placement Course

Mastering Data Structures & Algorithms, One Commit at a Time

---

This repository contains the complete Java + Data Structures and Algorithms (DSA) code from the Alpha Placement Course.The goal of this repository is to help students learn Java programming, master DSA concepts, and prepare for technical interviews and coding placements.

---

📚 Course Overview

The Alpha course focuses on building a strong programming foundation in Java and gradually moving toward advanced Data Structures and Algorithms.

Students will learn:

• Java programming basics
• Problem-solving using DSA
• Algorithm design techniques
• Coding interview preparation

This repository contains practice codes, examples, and implementations used throughout the course.
