A common problem in mathematics is to determine which quadrant a given point lies in. There are four quadrants, numbered from 1 to 4, as shown in the diagram below:

For example, the point A, which is at coordinates (12, 5) lies in quadrant 1 since both its x and y values are positive, and point B lies in quadrant 2 since its x value is negative and its y 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 0.

Input Specification

The first line of input contains the integer x (-1\,000 \le x \le 1\,000; x \ne 0). The second line of input contains the integer y (-1000 \le y \le 1000; y \ne 0).

Output Specification

Output the quadrant number (1, 2, 3 or 4) for the point (x, y).

    Just set the x and y to if it was negative or positive and it should be smooth sailing from there!
