For the purposes of giving specific names to specific things, a "Square" is one of the 3x3 portions of the Sudoku puzzle, containing GRID_BOUNDARY "Ti

Copy the values from one sudoku grid into another Note: O(n^2) Runtime Complexity @param oldArray @param newArray

Traverse all tiles and determine if any all are not 0. Note: GRID_BOUNDARY = GRID_BOUNDARY @param grid @return

Check to see if the incoming state (what the values of each square happen to be) of the game is either Active (i.e. Unsolved) or Complete (i.e. Solved

Checks the if the current complete or incomplete state of the game is still a valid state of a Sudoku game, relative to columns, rows, and squares. @

Creates and returns a new Array with the same values as the inputted Array. @param oldArray

Convenience method to reduce repetitious code. X, Y, Height, Width, @return A Rectangle to specification

Note: Arrays which do not use an initializer have all elements assigned to 0 by default. This is convenient, as 0 represents an empty square in the su

Start with the basic logic to validate a valid Sudoku puzzle

After spending several days sorting out how to generate a new valid sudoku puzzle, this test will confirm if my algorithm works.

Each time the user makes an input (which can be 0 to delete a number), we update the user interface appropriately.
