Rules: Given two grids are the same. Solve one, then turn the page upside down and solve the other. One view of the grid is a Skyscrapers puzzle, and the other one is a Gappy Skyscrapers puzzle. You should find out the correct views for each type and solve both.
Skyscrapers: Fill the grid with digits from 1 to 6 (1-4 for the example) so that each digit appears exactly once in each row and column. Each digit inside the grid represents a building with the height of the digit itself. Numbers outside the grid indicate the number of buildings that can be seen from the corresponding directions. Higher buildings block the view of lower buildings.
Gappy Skyscrapers: Follow Skyscrapers rules, except that there should be exactly one empty cell in each row and column. Use digits from 1 to 5 (1-3 for the example).
