Задача 21772. Clock change


Another winter has come in a flat country, and we urgently need to switch to winter time! The problem is that the hand of the city clock (the only one, by the way) located at the origin is very, very heavy, and therefore the workers want to know which way to turn the hand will be faster. To make things easier for you, they have already figured out where the arrow is pointing and where it should point. Help them!
 
Input
The first line specifies the point where the arrow is pointing. It is specified by the coordinates X1 and Y1 (\(- 10 <= X_1, Y_1 <= 10\)).
The second line specifies the point where the arrow should point. It is specified by X2 and Y2 coordinates (\(- 10 <= X2, Y2 <= 10\)).
Coordinates are given by the real type.
 
Output
On a single line print "Clockwise" if the arrow needs to be rotated clockwise, "Counter-clockwise" if it needs to be rotated counterclockwise , and "Doesn't matter", if it takes the same time, in which direction it would not be twisted. Phrases should be displayed without quotes.
