# sudoku-solver-cpp

A C++ Sudoku solver using **backtracking**. Takes an unsolved 9×9 board and fills in all valid solutions.

## How It Works

1. Find the next empty cell

2. Try digits 1–9

3. Check row, column, and 3×3 box constraints

4. Recurse — backtrack if stuck

## Build & Run

```bash

make

./sudoku

```

Or compile manually:

```bash

g++ -std=c++17 -O2 -o sudoku "Sudoku Solver.cpp"

./sudoku

```
