If the Can Place function returns true and then the sudoku solver also returns true then we print the solved sudoku matrix as an output otherwise print “Sudoku cannot be solved”.And if at any point we are unable to place any digit then we backtrack and remove the previously filled digit and try any another digit at that place and moves ahead.

To solve the sudoku we define a function named sudoku solver, in this function we recursively call the function to solve the sudoku and at every cell if a digit is correct to place or not, to check this we define a function named Can Place function, and in this function, we check if the digit has occurred in a row, column, or in 3X3 matrix(sub-matrix).

In the program in the main function, we initialize the sudoku matrix of size 9X9 and taking input from the sudoku matrix. Each player takes turns marking the board, with the first player to mark three in. The game board is a 3×3 grid, and players can either mark the grid with an X or an O.

It is a game of strategy and luck, and the goal is to be the first to mark either three X’s or three O’s in a row. Count problems to find a suitable solution. Tic Tac Toe is a classic two-player game written in Java.The best solution to optimize the algorithm.references Algorithmics of Sudoku may help. Decision-making problems to find a suitable solution to a problem. Sudoku - Rosetta Code Task Solve a partially filled-in normal 9x9 Sudoku grid and display the result in a human-readable format.Generally, backtracking involves starting with a possible solution, and if it doesn’t work, you backtrack and try another solution until you find the correct one.īacktracking is useful for the following three types of problems: Backtracking is a useful algorithm for solving the problem with recursion by building a solution incrementally. To solve the sudoku we use recursion with backtracking. The game initially has 9 squares combining rows. The playing grid of sudoku consists of the 99 squares space. In this packet, the C++ programming language is used to solve the Sudoku game. Sudoku is one of the most popular classic games. Sudoku is a logic-based combinatorial number-placement puzzle.
