Comet and Tracker

Time Limit: 2 Seconds      Memory Limit: 65536 KB      Special Judge

Tom invented a tracker which can track a comet. He want to know the position of the comet and the tracker in the process of time. After long-term study, he got some relatively simple formulas. When the coordinates of the comet is (x1, y1) and the tracker's is (x2, y2), the velocity vector of the comet is (-A*y1, B*x1) and the tracker's is (K*(x2-y1), K*(y2-x1)). A,B won't be negative and K is always positive. Tom knows the comet is at (x10, y10) and the tracker is at (x20, y20) now, he want to know where will the comet and the tracker be when the time passed t.

Input

There are multiple cases. Each case has 8 float numbers: A, B, K , x10, y10, x20, y20, t. Each number has at most 5 digits after the decimal point. (0≤ A, B ≤ 1; 0< K≤ 1; -5< x10, y10, x20, y20< 5; 0< t< 10)

Output

For each case, output x1(t), y1(t), x2(t), y2(t) in one line. Either absolute error or relative error of the output should be less than 10-8.
