Your mission is to calculate the area covered by a union of rectangles. The rectangles can have a non-empty intersection, which means that a simple sum of given rectangle areas doesn't work. Every rectangle is represented as 4 integers. The first two integers are the coordinates of a left-top corner, and the next two - of a bottom right corner.
Input: Iterable with tuples.
rectangles_union([ (6, 3, 8, 10), (4, 8, 11, 10), (16, 8, 19, 11) ]) == 33

Sync solutions into your local folder
(in beta testing) Launch local server so your browser can use it and sync solution between local file end extension on the fly. (doesn't work for safari)
checkio serv -d
Alternatevly, you can install Chrome extension or FF addon
checkio install-plugin --ff
checkio install-plugin --chromium
