The program fills in missing numbers in a 9x9 Sudoku grid while ensuring the solution follows Sudoku rules.\n\n## How It Works\n1. The program initializes a 9x9 Sudoku board with some prefilled numbers.\n2. It applies a **recursive backtracking algorithm** to find a valid solution.\n3. If a solution exists, the solved board is printed; otherwise, a message indicates that the board is unsolvable.\n\n## Features\n- Uses **backtracking** to find a valid solution.\n- Prints the Sudoku board **before and after** solving.\n- Ensures:\n  - Each row contains unique numbers (1-9).\n  - Each column contains unique numbers (1-9).\n  - Each 3x3 subgrid contains unique numbers (1-9).\n\n## Installation \u0026 Usage\n1. **Clone this repository**  \n   ```bash\n   git clone https://github.com/sofiasawczenko/sudoku.git\n   cd sudoku-solver\n\n2. **Compile and Run**\n   ```bash\n    javac SudokuSolver.java\n    java SudokuSolver\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsofiasawczenko%2Fsudoku","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsofiasawczenko%2Fsudoku","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsofiasawczenko%2Fsudoku/lists"}
