Package for this problem was not updated by the problem writer or Codeforces administration after we’ve upgraded the judging servers. To adjust the time limit constraint, solution execution time will be multiplied by 2. For example, if your solution works for 400 ms on judging servers, then value 800 ms will be displayed and used to determine the verdict.

standard outputVasily 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.

Input

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

Output

Print in the single line four integers *x*_{1}, *y*_{1}, *x*_{2}, *y*_{2} — the coordinates of the required points.
