## ✨ Key Features
* **Production-Grade Java**: Solutions written focusing on optimal runtime (`Time Complexity`) and memory usage (`Space Complexity`).
* **Concept Clearance Tools**: Deep-dives into fundamental data structures through custom implementations and mock test problems.
* **Modern Java Practices**: Code utilizes practical modern APIs up through Java 11 and Java 17.
---
## 📂 Repository Structure
The workspace follows a clean, standardized Java application layout:
* **[`src/`](./src)**: The main source folder maintaining all algorithm solutions, package definitions, and conceptual mock problems.
* **`.vscode/`**: Custom workspace configuration settings optimized for immediate execution in Visual Studio Code.
---
## 🧠 Topics Covered
This repository actively archives problems and solutions across these critical engineering domains:
### 🧩 Data Structures
* **HashMaps**: Collision handling, lookup optimization, and frequency counting.
* **Stacks & Queues**: Linear data pipelines, lifo/fifo ordering patterns, and buffer handling.
* **Arrays & Matrices**: In-place mutations, sliding window algorithms, and two-pointer passes.
### ⚙️ Design Patterns & Best Practices
* **SOLID Principles**: Object-oriented design blueprints for building modular, maintainable software.
* **Singleton Pattern**: Creational design workflows for thread-safe global access resource configurations.
### 🗄️ Database & Queries
* **SQL Queries**: Relational database operations, intricate joins, grouping, and analytical window functions.
---
## 💻 Getting Started
### Prerequisites
* Ensure you have the **Java Development Kit (JDK 11 or 17)** installed.
* **Visual Studio Code** with the *Extension Pack for Java* is highly recommended.
### Local Setup
1. Clone the repository:
```bash
git clone https://github.com/MrAkashKumar/leetcode-challanges.git
cd leetcode-challanges
```
2. Open the directory in VS Code. The IDE will auto-detect the compiled binaries workspace output path under the `bin/` folder.
