) and N(`x[2]`

,`y[2]`

). Find the coordinates of O(x,y), which divides it in ratio α.

## Input

In a single line the coordinates of segment endpoints and the number α are given. All coordinates do not exceed 100 by the absolute value.

## Output

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