Read in two integers that represent a vector (x, y) in a 2D space. Print out the quadrant number where the point is.

The 4 quadrants of a 2D space are:

Point P is in Quadrant II.

The input vector will always have exactly 1 quadrant. Ignore the case of points that are along the axis (e.g. 0,y and x,0 are not valid inputs).
