This is the code for our AP CSA command line sudoku project.
The following is an explanation of each function utilized in our program:
- writeMatrix(int[][] arr) Displays the Sudoku game board as a grid with the numbers placed in rows and columns.
- different(int random, int row, int col) Checks if inserting a number at a specific position in the Sudoku grid meets the game's rules of being different in rows, columns, and each 3x3 grid.
- letter(char A) Converts the input character for the column (A-I) into a numeric index (0-8).
- check(char A) Validates if the input character for row or column is within the valid range (A-I).
- randomHide() Randomly hides a certain number of elements in the Sudoku grid to create a puzzle for the player.
- gridNum(int i, int j, int rand) Assigns a number to the specified cell in the 3x3 grid section.
- softlock(int row, int col) Implements backtracking to solve the Sudoku puzzle and ensure the generated board is solvable.
- winner() Checks if the player has filled in all the numbers correctly, confirming a win condition.
- main(String[] args) The main function that orchestrates the entire Sudoku game, including generating the board, managing player input and game outcomes, and prompting the player for a rematch.
