Puzzle 19: Skyscrapers

Skyscrapers. Put a number between 1 and the length of a side of the grid such that each number appears exactly once in each row and column. If the numbers represent heights of buildings, the numbers outside the grid tell the number of visible buildings from that point looking into the grid, with higher buildings block lower ones in visibility. This one is somewhat easy.
