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

$\text{[math]}$

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

Input Specification

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

Output Specification

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

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