Practice 3.3: Bubbles
Make a program that uses an array to make bubbles float up the screen



Part A - Background

Your program should show a blue background.  Make sure the array is both declared and initialized!

Part B - Initial Placement and Drawing

ellipse(i * 20, yPositions[i], 20, 20);

A bunch of bubbles on the screen.  Look closely and you'll notice they are evenly spaced horizontally, but random vertically.

Part C - Movement

Your bubbles should be moving upward and wrap from the top of the screen
