The Skyline Problem

Understand how to solve the Skyline Problem by analyzing building positions and heights to produce the city’s outline. Explore using the union find pattern to efficiently identify height changes and avoid redundant skyline points. Gain hands-on experience designing a solution that handles complex building overlaps and transitions.

We'll cover the following...

Statement

Imagine standing at a distance, viewing the skyline of a city. The skyline is the shape formed by all the buildings in the city when viewed together. Your task is to determine the shape of this skyline, given all the buildings’ position and height. Each building is represented by three values in the array buildings, where buildings[i]=[lefti, righti, heighti]buildings[i] = [left_i,~right_i,~ height_i] ...
