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.
