Sweep Line Algorithm for Rectangle Union Area and Perimeter
Algorithm Overview
The sweep line algorithm efficiently computes the union area and perimeter of multiple overlapping rectangles. By simulating a line scanning across the plane and processing horizontal and vertical segments, it achieves O(n log n) time complexity.
Area Union Calculation
Problem Statement
Given n potentially overlapping rectang ...
