Problem type

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 $$x (-1000\le x \le 1000)$$ followed by the integer $$y (-1000 \le y \le 1000)$$.

#### Output Specification

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