Sudoku Solver

How it Works

This Sudoku solver uses dynamic programming (DP) to solve the puzzle. The algorithm works as follows:

• It iterates over each cell in the grid.
• For each empty cell, it tries all possible numbers (1-9) and checks if placing the number is a valid move.
• If placing the number is valid, it recursively attempts to solve the rest of the grid with the current configuration.
• If the grid is solved, it returns true, otherwise, it backtracks and tries the next possible number.
• Dynamic programming helps by memoizing (storing) previously computed results to avoid redundant calculations.
