The segment is given by the coordinates of its endpoints: M(x₁, y₁) and N(x₂, y₂). Find the coordinates of O(x, y), which divides it in ratio α.

   Input

   In a single line x1,y1,x2,y2 coordinates of segment endpoints and the number α are given(0< α<100). All coordinates do not exceed 1000 by the absolute value.

   Output

   Print in one line the coordinates x and y of the desired point, separated with one space. Print the result with two digits after the decimal point.
