/*
When a button is "clicked", perform the task described below:
 A: Change the background color, alternating between light-green and light-blue.
 B: Find the largest and smallest values in the array, and swap them.
 C: Replace each array element with random value (0-100) and recalculate the mean average.
 D: Change the array (and recalculate average):
 Double all values that are less than the mean average.
 Subtract 50 from all values that are greater than the mean average 
 E: Change the array (and recalculate average):
 Add ten to all odd values in the array;
 Divide all odd values by three. 
 F: Create a new ball (30 pixels diameter, randomly colored) at a random height on the left side.
 	Ball moves diagonally (2 down, 3 right), "bouncing" off all edges of the window. 
 	Ball vanishes if it hits (or comes within a 50-pixel radius of) mouse position.
