The Sudoku Solver is a utility that analyzes and completes Sudoku puzzles by systematically filling in empty cells while adhering to the rules of the game: each row, column, and 3x3 grid must contain all digits from 1 to 9 without repetition. It is widely used in puzzle solving, algorithm testing, and programming exercises where logical reasoning and constraint satisfaction are critical. For instance, when generating a Sudoku puzzle for practice or validating a partially completed grid, having an automated solver ensures that solutions are accurate and consistent.
