The coordinates of the vertices of triangle and one more point are given in Cartesian coordinate system. Determine whether the given point belongs the triangle.
The four lines contain two numbers - the points coordinates. The first three lines contain the coordinates of triangle vertices, the fourth line - the coordinates of the tested point. All coordinates are integer, for every point (x, y) the following condition is true: -10 000 ≤ x, y ≤ 10 000.
Print the word "In", if the point is inside a triangle or on its border, or "Out" - if outside.
