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

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!
