Section 22.10.1 introduced the gift-wrapping algorithm for finding a convex hull for a set of points. Assume that the Java?s coordinate system is used for the points. Implement the algorithm using the following method:

Point2D?is defined in Section 9.6.Write a test program that prompts the user to enter the set size and the points and displays the points that form a convex hull. Here is a sample run:

/** Return the points that form a convex hull */ public static ArrayList getConvexHul1(double[][] s) How many points are in the set? 6 -Enter Enter Enter 6 points: 1 2.4 2.5 2 1.5 34.5 5.5 6 6 2.4 5.5 9 The convex hull is (1.5, 34.5) (5.5, 9.0) (6.0, 2.4) (2.5, 2.0) (1.0, 2.4)
