Low-Level System Design Repository

Welcome to the Low-Level System Design repository! This repository is a comprehensive guide for mastering low-level system design concepts, with a focus on SOLID principles, design patterns, and practical design questions. It is structured to facilitate learning through a combination of theoretical explanations, UML diagrams, practical examples, and hands-on practice questions. The repo contains the collection of Questions generated with the help of ChatGPT.

📁 Repository Structure

The repository is organized into the following key sections:

1. Behavioural Design Patterns

• Folder Structure:

  LLD/
  └── Behavioural DP/
      ├── Chain of Responsibility DP/
      │   ├── Description.md
      │   ├── Question.md
      │   └── src/
      └── [Other Behavioural Design Patterns]/
  

• Contents:
  • Description: Provides a detailed introduction to the pattern, including a UML diagram, real-world examples, advantages, disadvantages, and a summary.
  • Question.md: Contains practice questions to test your understanding.
  • src/: Contains the solutions to the practice questions.

2. Structural Design Patterns

• Folder Structure:

  LLD/
  └── Structural DP/
      ├── [Structural DP 1]/
      ├── [Structural DP 2]/
      └── [Other Structural Design Patterns]/
  

• Contents:
  • Similar to the Behavioural Design Patterns, this section covers Structural Design Patterns in detail, with descriptions, UML diagrams, practice questions, and solutions.

3. Creational Design Patterns

• Folder Structure:

  LLD/
  └── Creational DP/
      ├── [Creational DP 1]/
      ├── [Creational DP 2]/
      └── [Other Creational Design Patterns]/
  

• Contents:
  • Detailed explanations of Creational Design Patterns, along with UML diagrams, examples, practice questions, and solutions.

4. SOLID Principles

• Folder Structure:

  LLD/
  └── SOLID Principles/
  

• Contents:
  • A thorough breakdown of the SOLID principles, with explanations, examples, and best practices for applying each principle in your designs.

5. Design Questions

• Folder Structure:

  LLD/
  └── Design Questions/
  

• Contents:
  • A collection of low-level design questions to challenge your understanding and application of the concepts covered. Each question comes with an in-depth solution to guide your learning process.

🎯 Purpose

This repository is intended to serve as a one-stop resource for anyone looking to:

• Master low-level system design concepts.
• Understand and apply SOLID principles in real-world scenarios.
• Gain expertise in various design patterns (Behavioural, Structural, and Creational).
• Practice design questions to prepare for technical interviews or real-world system design tasks.

🚀 Getting Started

To get started with the repository:

1. Clone the Repository:

   git clone https://github.com/snandkule/LLD.git
