Silhouette of some buildings in a city - Need help coding this algorithm, please!

[1_2_Soar]

Imagine the skyline of a city:- you are given (in integers)
(1) the x-coordinate,
(2) the height,
(3) and the width
measurements for a number of the buildings.

You are required to give the silhouette of those buildings in that city.

By the way, someone else has a descriptive posting in this problem domain (in the link provided below), in an entirely unrelated discussion.

I wish that, they had posted the solution as well.
