Vasily the bear has a favorite rectangle, it has one vertex at point (0,?0), and the opposite vertex at point (x,?y). Of course, the sides of Vasya's favorite rectangle are parallel to the coordinate axes.

Vasya also loves triangles, if the triangles have one vertex at point B?=?(0,?0). That's why today he asks you to find two points A?=?(x1,?y1) and C?=?(x2,?y2), such that the following conditions hold:

the triangle formed by point A, B and C is rectangular and isosceles ( is right);

Help the bear, find the required points. It is not so hard to proof that these points are unique.
