Web16 giu 2024 · Using the backtracking algorithm, we will try to solve the Sudoku problem. When some cell is filled with a digit, it checks whether it is valid or not. When it is not valid, it checks for other numbers. If all numbers are checked from 1-9, and no valid digit found to place, it backtracks to the previous option. Websure you have the heart of the algorithm correct and allows the other pieces to be developed, test, and debugged independently. First, let's just take the exhaustive permutation code and change it into a backtracking algorithm.
