# StrategySort-MVC-WinForms

A lightweight C# WinForms application that demonstrates string sorting using various algorithms. This project implements the **Strategy Pattern** for algorithm selection and the **MVC (Model-View-Controller) Pattern** to ensure a clean separation of concerns.

## 🚀 Features

* **Custom String Sorting:** Input any text and sort its characters alphabetically.
* **Multiple Algorithms:** Choose between Bubble Sort, Merge Sort, and Quick Sort.
* **Architectural Excellence:** Built using MVC and Strategy design patterns.
* **Robustness:** Includes a dedicated Unit Test project to ensure sorting accuracy.

## 🛠 Architecture

This project is designed with scalability and maintainability in mind:

### 1. Strategy Pattern
The sorting logic is decoupled from the main application. Each algorithm implements a common `ISortStrategy` interface, allowing the program to swap sorting behaviors at runtime without changing the client code.



### 2. MVC Pattern
* **Model:** Handles the data logic and the execution of the sorting strategies.
* **View:** The WinForms interface (`TextSortWindow`) which captures user input and displays results.
* **Controller:** Acts as the bridge between the View and the Model, processing user commands and updating the UI.

## 📸 How It Works

1.  **Input:** Enter any string into the text box (e.g., `github`).
2.  **Select Strategy:** Choose a sorting algorithm from the ComboBox:
    * `Bubble Sort`
    * `Merge Sort`
    * `Quick Sort`
3.  **Sort:** Click the **Sort** button.
4.  **Output:** The sorted result (e.g., `bgghitu`) appears in the output label.

## 🧪 Unit Testing

The solution includes a `Testing` project using **MSTest** to validate the sorting logic.

* Tests verify character sorting for empty strings, special characters, and long strings.
* Ensures all three strategies return consistent results.
