Day 2: Mastering Object-Oriented Programming 🧠📦 | OOP Refresher for Low-Level Design

Описание: Welcome to Day 2 of our 62-Day Low-Level Design (LLD) Masterclass!
Today, we dive deep into the core principles of Object-Oriented Programming (OOP)—the foundation for designing scalable and maintainable systems. From encapsulation to polymorphism, learn how to apply these concepts in real-world LLD with clarity and confidence. 🚀
👉 Includes theory, real-life analogies, design exercises, and common pitfalls to avoid.
Perfect for engineers preparing for system design interviews or building production-level architecture!
