Sudoku solving algorithms

Sudoku solving algorithms refer to the various methods and techniques used to solve Sudoku puzzles. These algorithms can range from simple, heuristic-based approaches to more complex, systematic methods. Here are several common types of algorithms used for solving Sudoku: ### 1. **Backtracking Algorithm** - **Description**: This is one of the most straightforward algorithms for solving Sudoku. It uses a brute-force approach, testing each number in the empty cells and backtracking when an invalid placement is found.
