1.	Which of the following factors account more to the cost of Chan’s algorithm?(a) computing a single convex hull(b) locating points that constitute a hull(c) computing convex hull in groups(d) merging convex hullsThis question was addressed to me during an interview for a job.My doubt is from Computational Geometry topic in chapter Computational Geometry of Data Structures & Algorithms II
Answer» The correct answer is (C) COMPUTING CONVEX hull in groups Easiest EXPLANATION - The majority of the cost of the algorithm lies in the pre-processing (i.e.) computing convex hull in groups. To reduce cost, we reuse convex hulls from previous ITERATIONS.
