The vertices of triangle have integer coordinates. Find any point with integer coordinates strictly inside the triangle. A point must not belong to the boundary of a triangle.

Input

Contains three lines with two integers in each line: xi, yi (-106 ≤ xi, yi ≤ 106) - the coordinates of triangle vertices. It is guaranteed that the triangle is non-degenerate.

Output

If there is no required point, print "No". Otherwise print two integers - the coordinates of any point strictly inside the triangle.
