Project 1-Sudoku Solution Validator A Sudoku puzzle uses a 9 9 grid in which each column and row, as well as each of the nine 3 3 subgrids, must contain all of the digits 1 . . . 9. Figure 4.19 presents an example of a valid Sudoku puzzle. This project consists of designing a multithreaded application that determines whether the solution to a Sudoku puzzle is valid. There are several different ways of multithreading this application. One suggested strategy is to create threads that check the following criteria: A thread to check that each column contains the digits 1 through 9 .A thread to check that each row contains the digits 1 through 9 Nine threads to check that each of the 3 3 subgrids contains the digits 1 through 9 This would result in a total of eleven separate threads for validating a Sudoku puzzle. However, you are welcome to create even more threads this project. For example, rather than creating one thread that checks all nine
