The last week's topics depend on the instructor as there are a few optional things.
Rather than focusing too much on the new topics, 
I suggest spending most time reviewing old topics for the Final.
You can put together some predict the output / error spotting exercises 
from earlier weeks for practice. 


##################################### Discussion 1
REVIEW: Passing arrays to functions, range-based for loops
Final practice

##################################### Discussion 2
REVIEW: sets, unordered sets, recursion, 
Final practice
