"Final Scaled" is your final exam grade. I scaled the final exams, therefore it says "scaled".

The correct grades are not in the column "Final Grade Corrected". I apologise to those who had a wrong grade initially and were disappointed.

Hi everyone, Please ignore the course grade I entered for now. If you had 100 for an assignment, I erroneously converted it to "0" in my spreadsheet. So your final grade will have an error. I'll correct this today.

To 450:
If you mean complexity of function "incident edges" then the answer is yes.

To 449: I explained this in class many times, you should ask questions after class if you don't understand.

Is deg(u) O(m) in the worst case only for undirected graphs? or is it also for directed graphs

How can we determine the number of edges in a graph, such as in the question 12 on the practice exam? It refers to strongly connected/transitive closure specifically.

I was wondering if, just like the midterm, we are allowed to bring lecture notes to the exam?

Can there be more than 2 answers for the topological question in the exam?

444: These issues were extensively discussed during lectures. You have to follow the same algorithm as described in class.

I've seen some examples for 2,4 Tree insertion when overflow occurs, instead of moving the 3rd item to the parent, they move the 2nd item to the parent when doing a split. Are both of these correct or do you want us to stick with moving the 3rd one to the parent?
Thank you

No, A and G can be swapped as well.

For the topological question in the practice exam there is more than 2 solutions right?

I might be slightly late for the review session today.
