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 \((x,y)\).

Sample Input 1

12 5

Sample Output 1


Sample Input 2

9 -13

Sample Output 2
