Shapeskyscrapers (345)

Place all of the given shapes into the grid. The shapes may be rotated and/or reflected. Shapes cannot cover the cells marked with ‘×’. Shapes cannot touch each other (not even diagonally). The numbers outside the grid indicate how many black segments (groups of adjacent black cells) can be “seen” in the respective row or column from the respective direction; shorter and equally-sized segments are “hidden” behind longer ones.
