This repository contains a Sudoku solver implemented in C++. The solver uses a backtracking algorithm to find a solution to a given Sudoku puzzle. It is capable of solving puzzles of varying difficulty levels.

The Sudoku solver program reads a Sudoku board, solves it using a backtracking algorithm, and prints the solved board. The Sudoku board is represented as a 9x9 grid where 0 denotes an empty cell.

1. Validation: The isValid function checks if placing a number in a specific cell is valid according to Sudoku rules.
2. Solving: The solveSudoku function uses recursion and backtracking to fill the board with numbers.
3. Printing: The printBoard function formats the board for easy reading.

To use the Sudoku solver:

1. Clone this repository:

   git clone https://github.com/yourusername/sudoku-solver.git
   

2. Navigate to the project directory:

   cd sudoku-solver
   

3. Compile the code:

   g++ -o sudoku_solver sudoku_solver.cpp
   
   

4. Run the executable:

   ./sudoku_solver
   
   

The provided code includes a sample Sudoku puzzle. When you run the program, it will output the solved Sudoku board.
