WebAs in the usual divide and conquer algorithms, it has three major steps: Divide: We divide the set of n points into two parts by a vertical line into the left and right halves. Conquer: We recursively find the convex hull on left and right halves. Combine or Merge: We combine the left and right convex hull into one convex hull. Web1) Initialize p as leftmost point. 2) Do following while we do not come back to the first (or leftmost) point. a) The next point q is the point such that the triplet (p, q, r) is counterclockwise for any other point r. b) next[p] = q …
