Java Developer Needed for puzzle Game

Background Introduced code to solve a Sudoku puzzle. After working with the class, users had two observations: - Making puzzles is not convenient, as witnessed by the long bits of code in some of the JUnit test cases - Not all Sudoku puzzles have a unique solution, which makes testing harder because we don’t know if the solution that the class produces will match the solution that our test case outlines. The class code, has added a new method called solveMany( ) to produce multiple solutions to a puzzle (if multiple solutions exist). Problem The task is twofold: make it easier for users to define puzzles and help uses make sense of the output from solveMany( ). The specifics of your task are provided in a separate requirements document. The focus should be in the process you follow to create the solution. Specifically: 1. Design your solution and document it in the external documentation file. 2. Create test cases for the code that you are about to create. Implement those test cases in JUnit. 3. Implement each of the methods of your solution, as each method is complete and passes its tests 4. Revisit your test cases to determine if any tests should be added or refined. If yes, add the tests and ensure that your code passes them.
