Write quadrant(x, y) that returns which quadrant of the coordinate plane the point (x, y) lies in: 1 (both positive), 2 (x negative, y positive), 3 (both negative) or 4 (x positive, y negative). If the point lies on either axis (x or y is 0), return 0.
Examples
Input: x = 3, y = 4
Output: 1
Input: x = -2, y = 5
Output: 2
Input: x = 0, y = 7
Output: 0
Constraints
-1000 <= x, y <= 1000
Goals
- Combine the signs of two numbers with and
- Treat points on an axis as a separate case
