Canadian Computing Competition: 2017 Stage 1, Junior #1

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

Output Specification

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