Sudoku is a wildly popular puzzle game. Sudoku puzzles are 9x9 grids, and each square in the grid consists of a 3x3 subgrid called a region. Your goal is to fill in the squares so that each column, row, and region contains the numbers 1 through 9 exactly once. And some squares already contain numbers or symbols, which lend clues toward the solution.
