Greater Than Skyscrapers (439)

Place number from 1 to N where N is the size of the grid into each cell so that each digit appears exactly once in any row or column. Each number in the grid represents the height of a skyscraper. The clues outside of the grid indicate how many skyscrapers can be seen when looking from the corresponding direction. Higher skyscrapers block the view of smaller ones. If there is an inequality sign between a pair of orthogonally adjacent cells, the numbers in these cells must be placed according to the given sign.
