Solution: The Skyline Problem

Explore how to solve the skyline problem by computing the city outline using a union-find data structure. Learn to merge overlapping building segments, track height changes efficiently, and build a clean skyline representation in C++. Understand the algorithm's time and space complexities.

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] ...
