We consider the following Sudoku puzzle and only focus on the shaded squares. Use the constraint propagation technique as we did in class to fill in each of the shaded

squares with the minimum number of candidate numbers in the increasing order and without space $($e$.$g$.,4689,$ otherwise the autograder won't detect it correctly$).$ For

each shaded square, please use only the three constraints $($row$,$ column, and subgrid$).$ Don't fill in other empty squares.
