There is a cycle with its center on the origin. Now give you a point on the cycle, you are to find out the other two points on it, to maximize the sum of the distance between each other you may assume that the radius of the cycle will not exceed 1000.
输入解释
There are T test cases, in each case there are 2 decimal number representing the coordinate of the given point.
输出解释
For each testcase you are supposed to output the coordinates of both of the unknow points by 3 decimal places of precision Alway output the lower one first(with a smaller Y-coordinate value), if they have the same Y value output the one with a smaller X.
NOTE
when output, if the absolute difference between the coordinate values X1 and X2 is smaller than 0.0005, we assume they are equal.
