10 Build the Sudoku Reviewer ( the testing program). The specification is below. Please note: you DO NOT have to build a Sudoku solver. To test you just need to build a class that generates a 9x9 2D array with the values you want to test. You can assume the value types are valid. (integers from 1-9). 1-The main purpose is to make sure the Sudoku solver actually solved it correctly! 2- You are also confirming the solver solves puzzle in no longer than a minute 3- Solver (not the reviewer) requires 7 INDICES (ELEMENTS) filled in the input array at least. 4- The reviewer receives both the original puzzle and the solution. The Reviewer needs to confirm the solution is not only a valid SudoKu solution but also the solution to the original puzzle. 5- Solver will return a 2d array filled with -1s if input array has an error/bad input (exception). Reviewer will check for this case.
