Each bold region must contain at least one labeled cell. Each number (including any given numbers) must equal the total count of labeled cells in that region. When two numbers are orthogonally adjacent across a region boundary, the numbers must be different. (Note: While not required, it may be helpful to shade in the unused cells, as seen in the solution here.) <\/p>\n<p><b>Answer String:<\/b> Enter the length in cells of each of the segments labeled with numbers from left to right for the marked rows, starting at the top. Separate each row&#8217;s entry with a comma.
