A common problem in mathematics is to determine which quadrant a given point lies in. There are four quadrants, numbered from to , as shown in the diagram below:

For example, the point A, which is at coordinates lies in quadrant since both its and values are positive, and point lies in quadrant 2 since its value is negative and its value is positive.

Your job is to take a point and determine the quadrant it is in. You can assume that neither of the two coordinates will be .

#### Input Specification
