Solution: The Skyline Problem

Explore how to determine a city skyline from building coordinates and heights using the union find pattern. This lesson guides you through merging overlapping buildings efficiently and implementing a solution with time complexity O(n log n), helping you understand both problem decomposition and algorithm optimization in coding interviews.

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] ...
