Java Programming

Write a Sudoku validator for 4x4 grids made up of 2x2 regions instead of 9x9 grids made up of 3x3 regions. Sudoku puzzles that use 4x4 grids only use the numerical digits 1 through 4 instead of 1 through 9.


Things to Remember:

-Dont use arrays
-Input 16 values into 16 seperate variables
-Try using only if and if/else statements


Outcome should look something like this:

Welcome to the Sudoku Checker v1.0!

This program checks simple, small, 4x4 Sudoku grids for correctness. Each column, row and 2x2 region contains the numbers 1 through 4 only once.

To check your Sudoku, enter your board one row at a time, with each digit separated by a space. Hit ENTER at the end of a row.

Enter Row 1: 1 2 3 4
Enter Row 2: 3 4 2 1
Enter Row 3: 1 2 3 4
Enter Row 4: 4 3 2 1
