Recently I started learning Haskell by studying the Intro to FP Programming course on Edx. Since then, I try to model different problems using Haskell.

One of these problems is the Skyline problem, which goes like this:

You are given a set of rectangular buildings in a city, and you should return the skyline view of the city. Input is a sequence of tuples (x_{left}, height, x_{right}), each describing a building. The output is a sequence of pairs (x, height) meaning that the height of skyline changed to height at the given x coordinate.
