Snack 1: Renban skyscrapers 9x9

(Published on 2. December 2010, 13:00 by RobertBe)

Fill each cell inside the grid with a digit from 1 to 9. Every digit must appear once in any row or column. Every digit inside the grid represents a building with a specific height. The digits outside the grid (which are also to be determined by you) indicate the number of buildings visible from that direction. A building is visible if all the other buildings are lower than it. Cells with the same color must contain consecutive (all different) digits, even when they are not connected.

Solution code: The diagonals, first from top left to bottom right, then from top right to bottom left

@Dugong: there is also a renban condition on the grey cells. Your solution would have 224 for this renban, which is invalid.

Changed due to a question regarding the meaning of consecutive. Meant is of course three or nine different numbers, like 2,3,4 of 6,8,7 or ...

Robert, it seems you've done some studies after my Hochhausblöcke. Fine!
