Android coding challenge

We wanted you to complete the code challenge which is a pre-requisite before scheduling the client conversation. You will need to complete the attached code challenge and return within 24 hours. Photon Team will evaluate the code kata and provide you with feedback before submitting for client. Attached is also short one pager of Developer Guidelines. They do not expect all developers to be an expert in all of the points, however a developer should be aware of all items on the page and be able to demonstrate an understanding of all the points. If you have created apps you can share the code on github as well. Instructions - 1. Can you ensure you implement the solution using TDD approach to developing the application. There are many good articles on the web about TDD development patterns. 2. Specifically, we are looking for tests to drive the design and development of the code. To do that, tests are written in conjunction with the code (often before the code). 3. Code should be properly factored into appropriately named/intentioned TDD-ed classes with appropriate separation of concerns. 4. Share your code through github link 5. Please write test cases as TDD approach is followed and client requests test cases to be submitted 6. Make sure GUI has option to input values for testing. 7. There should be comments with code. After you complete the code, please check it for the below inputs. we need correct output for all the cases. You can include them as part of your test cases.
