Given a set of points in the plane, we define the convex layers of Q inductively. The first convex layer of Q consists of those points in Q that are vertices of CHQ). For i > 1, define Qi to consist of the points of Q with all points in convex layers 1,2,...,i-1 removed. Then, the ith convex layer of Q is CHQ:) if Qi 70 and is undefined otherwise. Give a O(n)-time algorithm to find the convex layers of a set of n points. Justify the correctness of your algorithm and its running time. Do NOT use Jarvin March algorithm, just adapt Graham Scan.
