I would like to contribute to the project by adding a new feature: a GCD (Greatest Common Divisor) quiz mode. This feature will present users with a series of problems requiring them to find the GCD of given pairs or sets of numbers, enhancing the educational value of the application. Rationale: The GCD is a crucial concept in mathematics, particularly in number theory, and understanding it is important for students and enthusiasts alike. A quiz mode dedicated to GCD problems will provide an interactive and engaging way for users to practice and reinforce their understanding of this concept. Proposed Implementation: User Interface: Add a new option in the main menu or toolbar for the GCD quiz mode. Design a quiz interface where users are presented with a GCD problem and input their answer. Provide feedback on whether the answer is correct or incorrect and display the correct answer if wrong. Include a progress tracker showing the number of questions answered correctly. Quiz Logic: Generate random pairs or sets of integers for each quiz question. Ensure the difficulty level can vary, with simpler problems for beginners and more complex ones for advanced users. Implement a scoring system to track user performance. Backend Logic: Use the Euclidean algorithm to compute the correct GCD for quiz problems. Maintain a question pool with a variety of problem types and difficulty levels. Testing: Develop a suite of tests to ensure the quiz mode generates correct GCD problems and accurately evaluates user answers. Test the user interface for usability and responsiveness. Benefits: Provides an interactive learning tool for users to practice GCD calculations. Enhances the educational value of the application, making it more appealing to students and educators. Offers a fun and engaging way to reinforce mathematical concepts. Conclusion: I am enthusiastic about contributing to this project and believe that the addition of a GCD quiz mode will be a valuable enhancement. I have experience in [mention relevant experience or background], and I am confident in my ability to implement this feature effectively. I am looking forward to your approval to start working on this task. Thank you for considering my proposal. Best regards, Yusuf Azam mygithubprofile:-https://github.com/yusufazam225
