Write a function that uses the same process to draw a vertical line down the middle of the picture, and a horizontal line across the middle of the picture, neatly separating the picture into four quadrants. This function can work for any square or rectangular picture.

What will be an ideal response?

```
def drawQuadrants(picture, lineColor):
vertical = getWidth(picture)/2
horizontal = getHeight(picture)/2
for p in getPixels(picture):
x = getX(p)
y = getY(p)

if y==vertical:
setColor(p,lineColor)
if x==horizontal:
setColor(p,lineColor)
```

Note: The question does not specify that a line color should be passed in, so one can just write a function that always uses the same color.
