Solution: The Skyline Problem

Explore how to solve the Skyline Problem by combining building outlines into a unified skyline shape. Understand step-by-step how union-find helps merge overlapping segments, track maximum heights, and remove redundant lines, all while managing time and space complexity for efficient results.

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.
