Description
Suwa Yorishige, excited by Tokiyuki's success in solving the assignment, decided to give him a more challenging task. Unsurprisingly, Tokiyuki couldn't solve it on his own and came back to seek your help.
Given two points P(x1 , y1) and Q(x2 , y2) on a plane, output the slopes between each point and the origin O(0, 0).
If the slopes of the two points are the same, output "yes"; otherwise, output "no".
Input
The first line contains two integers x1 , y1 .
The second line contains two integers x2 , y2 .
Constraints
-
x1, x2 ≠ 0, -109 ≤ x1, x2, y1, y2 ≤ 109.
Output
The first line outputs two floating-point numbers representing the slopes of P and Q with respect to O, separated by a space, rounded to three decimal places.
The second line outputs whether the slopes of the two points are the same. If they are the same, output "yes"; otherwise, output "no".
Please remember to print "\n" at the end.
