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 ...
