I have been quite busy over the weekend... I have graded your exercises and evaluated the competition.
You can find the new slides online, the new exercise sheets and an example solution for symbol-based indexing. Note that this solution may not be very efficient; instead it was tuned for readability.
Also, if you have not done so yet, I would appreciate if you could fill out the following questionnaire. Thanks!
