A point (x, y) in the Cartesian plane is said to be dominated by point (x, y), if x, x, and y, sy, with at least one of the two inequalities being strict. Given a set of 1 points, one of them is said to be an extreme of the set, if it is not dominated by any other point in the set. For example, in the figure below, all the extreme points of the set of 10 points are circled. Given a set of point coordinates in the Cartesian plane, generate the subset of extreme points. Example: Input set ((45, 1.2), (5.1.-4.2), (21, 8.6), (-6.3, 15.2), (1.5.5.2), (3.4, 1.8) 13.4.4.2), (8.1. 3.21, (45,7.9) (58,-2.3)) Output extremes (12.1, 8.6), (-63, 15.21, (4.5.7.9), (98.-2.3))
