A8619. Hit Ball

编程题 普及/提高-

题目描述

The first line contains three space-separated integers $a,b,m$ $(1<=a,b,m<=100)$ . The first two integers specify point $(a,0,b)$ , through which the ceiling and one of the corridor walls pass. The third integer is the distance at which Valera went away from the door.

The second line has three space-separated integers $v_{x},v_{y},v_{z}$ $(|v_{x}|,|v_{y}|,|v_{z}|<=100,v_{y}<0,v_{z}>=0)$ — the speed of the ball after the hit.

It is guaranteed that the ball hits the door.

输入格式

Print two real numbers $x_{0},z_{0}$ — the $x$ and $z$ coordinates of point $(x_{0},0,z_{0})$ , at which the ball hits the exit door. The answer will be considered correct, if its absolute or relative error does not exceed $10^{-6}$ .
