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.

The first line of input contains the integer $x\ (-1,000≤x≤1,000;\ x\neq 0)$. 

The second line of input contains the integer $y\ (-1,000≤y≤1,000;\ y\neq 0)$.
