## CCC '17 J1 - Quadrant Selection

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

`1`

#### Sample Input 2

`9 -13`

#### Sample Output 2

`4`
