# Kattis - quadrant
[題目連結](https://open.kattis.com/problems/quadrant)
## 題目敘述
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 $0$.
:::success
一個數學上常見的問題是給你一個座標點,問你這個點落在第幾象限上。
象限被編號為 $1$ 到 $4$,如圖所示。
(見上圖)
例如座標為 $(12,5)$ 的點 $A$ 因為 $x$ 和 $y$ 皆為正數,因此落在第一象限;
而點 $B$ 因 $x$ 為負、$y$ 為正,因此落在第二象限。
你的任務是對給予的點座標,計算出它落在第幾象限上。
題目保證 $x$ 和 $y$ 都不會是 $0$。

## 輸入格式
The first line of input contains the integer $x$ $(−1000\le x\le 1000;x\ne 0)$. The second line of input contains the integer $y$ $(−1000\le y\le 1000;y\ne 0)$.
:::success
輸入第一行包含一整數 $x$ 保證 $(−1000\le x\le 1000;x\ne 0)$;
第二行包含一整數 $y$ 保證 $(−1000\le y\le 1000;y\ne 0)$。

## 輸出格式
Output the quadrant number $(1, 2, 3$ or $4)$ for the point $(x,y)$.
:::success
對於點 $(x,y)$ 輸出它所在象限 $(1, 2, 3$ 或者 $4)$
