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 to , as shown in the diagram below:
For example, the point , which is at coordinates lies in quadrant since both its and values are positive, and point lies in quadrant 2 since its value is negative and its 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 .

no math required
Just set the x and y to if it was negative or positive and it should be smooth sailing from there!
