Goal: Identify and correct the wrong entries in the Sudoku grid. Rules: - Use the row and column Nonogram clues to determine which cells must be shaded. - Every shaded cell marks an incorrect Sudoku entry; unshaded entries remain fixed. - Replace the incorrect entries so each row, column, and 3×3 box contains the numbers 1–9 exactly once.
