Consider the following code. Assume that copy has been imported. W = [1, 2] z = copy.copy (w) z = copy.deepcopy (w) print (z + w) Z = W 4. (2 points) How many different objects will exist in the computer's memory after the code has been executed? Assume that no optimizations have been performed and that garbage collection has been executed. 5.
