CF336A.Vasily the Bear and Triangle

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 $A=(x_{1},y_{1})$ and $C=(x_{2},y_{2})$ , such that the following conditions hold:

• the coordinates of points: $x_{1}$ , $x_{2}$ , $y_{1}$ , $y_{2}$ are integers. Besides, the following inequation holds: x_{1}<x_{2} ;
• the triangle formed by point $A$ , $B$ and $C$ is rectangular and isosceles ( is right);
• all points of the favorite rectangle are located inside or on the border of triangle $ABC$ ;
• the area of triangle $ABC$ is as small as possible.

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

The first line contains two integers $x,y$ $(-10^{9}<=x,y<=10^{9},x≠0,y≠0)$ .

Print in the single line four integers $x_{1},y_{1},x_{2},y_{2}$ — the coordinates of the required points.
