Sudoku Validator

The Sudoku Validator is a Rust program that validates a Sudoku puzzle using multithreading. It checks if the given Sudoku puzzle is valid by ensuring that each row, column, and 3x3 subgrid contains the digits 1 through 9 without repetition.

Prerequisites

To compile and run the Sudoku Validator program, you need to have the following installed on your system:

• Rust (version 1.x.x)

Getting Started

1. Clone the repository or download the source code files.

2. Open a terminal or command prompt and navigate to the directory where the source code files are located.

Compiling the Program

To compile the Sudoku Validator program, use the following command:

rustc sudoku_validator.rs

Running the Program

To run the Sudoku Validator program, use the following command:

./sudoku_validator

This command executes the compiled Sudoku Validator program, which validates the predefined Sudoku puzzle.

Modifying the Puzzle

By default, the program uses a predefined Sudoku puzzle grid for validation. If you want to validate a different Sudoku puzzle, you can modify the grid array in the main() function of the sudoku_validator.rs file. Update the values in the grid array to represent your Sudoku puzzle. Each row of the puzzle corresponds to a subarray in the grid array, and each digit in the puzzle is represented by an integer value. For example, to validate a different Sudoku puzzle, you can modify the grid array as follows:

let grid = [

[6, 3, 4, 6, 7, 8, 9, 1, 2],
[6, 7, 2, 1, 9, 5, 3, 4, 8],
[8, 9, 8, 3, 4, 2, 5, 6, 7],
[8, 5, 9, 7, 6, 1, 4, 2, 3],
[4, 2, 6, 8, 5, 3, 7, 9, 1],
[7, 1, 3, 9, 2, 4, 8, 5, 6],
[9, 6, 1, 5, 3, 7, 2, 8, 4],
[2, 8, 7, 4, 1, 9, 6, 3, 5],
[3, 4, 5, 2, 8, 6, 1, 7, 9],

];

After modifying the grid array, save the changes and recompile the program using the rustc command mentioned earlier.

Validation Result

After running the program, it will display the validation result in the console. If the Sudoku puzzle is valid, it will print "The Sudoku puzzle is valid." Otherwise, it will print "The Sudoku puzzle is not valid."

Troubleshooting

If you encounter any issues while compiling or running the program, ensure that you have Rust installed correctly on your system.
