I have N rectangles with sides parallel Ox and Oy. Exists another rectangele (model). I need create algorithm, which can tell: is model covered by N rectangles? and code him.

I have some ideas. First I think need sort rectangles by left side (it can be done by O(n log n)). Then I think need use vertical sweeping line.

Thanks.
