Question $2(10$ points$)$:

Purpose: To work with the concept of references a bit more carefully.

Degree of Difficulty: Easy. If you understand references very well, this is not difficult.

For each of the $5$ copy$()$ functions in the file a$3$q$2.$py$,$ do the following:

$$ Determine if the function makes a copy of the list. Hint: some do not!

$$ Determine if the function is suitable for use in selection$\_$sort$().$ Hint: some are not!

Do not change the function selection$\_$sort$()$ except to make use of one of the versions of the copy$()$

function on line $11.$ Do not change the code for any of the copy$()$ functions. You will only need one or two

lines of code to use the different functions, but exactly how many you need is part of the problem.
