Quickhull Algorithm for Convex Hull
Given a set of points, a Convex hull is the smallest convex polygon containing all the given points. Input : points[] = {{0, 3}, {1, 1}, {2, 2}, {4, 4}, {0, 0}, {1, 2}, {3, 1}, {3, 3}};Output : The points in convex hull are: (0, 0) (0, 3) (3, 1) (4, 4)Input : points[] = {{0, 3}, {1, 1}Output : Not P
