Puzzle #92 - Skyscrapers

Here's a large Skyscrapers puzzle with relatively few clues and a tricky resolution.

Rules

Place a number from 1 to 9 into each cell of the grid so that every row and column contains each number exactly once. Each number inside the grid represents a building of that height, and clues outside the grid indicate how many buildings can be seen when looking along the corresponding row or column from the position of the clue. Higher buildings block the view of smaller buildings behind them.

Difficulty: 9/10
