Problem J1: Quadrant Selection

Time limit: 1 second

Problem DescriptionCopy Anchor Link

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 $x$ $(-1000 \leq x \leq 1000; x \not= 0)$. The second line of input contains the integer $y$ $(-1000 \leq y \leq 1000; y \not= 0)$.
