20.6

[Colin Thompson]

For 20.6 are we supposed to mutate the elements of the array to the
average values and return void, or are we supposed to make a new array
and return that?

"it takes an array of prices and replaces the values with their moving averages."

Are we allowed to make a new array to help us that we do not return?

[Jay McCarthy]

I guess, although I can't think of why that would be useful. Take what you did in #5 and convert it to a while loop with mutation and array rather than a list. There's no intermediate array there. Also, you can't really make new arrays you're stuck with the ones you start with.
