ABC-Sky with regional match (742)
Instruction:
Solve two puzzles - As Easy as ABC and Skyscrapers with parks. Both puzzles use numbers in the range 1-4,
two cells remain empty in each row/column. The grey regions are identical. No information is given on the white regions (the cells may or may not be identical).
As Easy as ABC (left grid)
Enter the numbers 1 to 4 into the diagram, so that in every row and every column every number occurs exactly once; in every row and every column two cells remain empty. The numbers at the borders indicate the number that comes first from the given viewpoint.
Skyscrapers with parks (right grid)
Place numbers from 1-4 in some of the cells so that they do not repeat in rows and columns. Two cells in each row and column remain empty. The numbers represent heights of the buildings. The numbers around the grid indicate the number of buildings you can see from the given viewpoint. The building is visible only when it is higher than all the buildings in front of it.
