CMSC420-0201: Lecture - Shared screen with speaker view
Bailey Fokin
17:25
when you say open internet, you mean the course material on the website?
Sharon Halevi
18:58
Will the exam be a pdf on gradescope? Could we download it so we can continue working if our internet goes out?
Olayemi Oyindamola Ajayi
19:19
yes
Sonya Rumenova Radichkova

ues
Sonya Rumenova Radichkova
19:23

Maya Fuchs

We won't have classes Thursday, will we?
Maya Fuchs

Maya Fuchs

lol
William Cao
20:31
can we upload the same pdf for all the sections?
Olayemi Oyindamola Ajayi
20:39
^
Maya Fuchs
20:52
thanks!
William Cao
20:54
because often it's easier to just do all the work
William Cao
20:56
in 1 document
William Cao
22:42
how many questions?
William Cao
22:45
are we estimating
William Cao
22:47
on the exam?
Jane Li
22:50
if we submit everything in 1 file, how would we submit on gradescope?
James Brunner
28:01
Could we potentially have proofs?
Afe Addeh
28:30
I noticed on the practice midterm there's a lot of proof and proving things in terms of n. Will that be the case on the midterm?
Olayemi Oyindamola Ajayi
31:23
Are you writing something on a different screen?
Kira Loshin
31:27
Should we be able to see the screen right now?
Kamtochukwu Okafor
31:40

William Cao
35:37
wait you could give 48 hours and scale difficulty
Rahul Khanna
40:12
Is there gonna be true/false on the exam?
Sharon Halevi
41:21
Wouldn’t showing your thought process favor uploading your own document rather than filling out the exam template on gradescope?
Yaeji Shin
45:38
Could there be a printable option for the exam similar to the homework template?
Hyen Jeong
45:40
Is it okay to write every single answer on paper and upload on the last question?
William Cao
45:48
you can print the page
Hyen Jeong
46:05
yeah but can we upload that page on the last question?
Bailey Fokin
51:49
R.I.P to all the trees that were used for my answers to HW2
Bailey Fokin
53:28
Say we did everything correct except we forgot about node 8, how many points do you think we wouldn lose for that?
Neehar Peri
54:15
How big can we expect trees to be on the exam?
John Heide
58:06
If I did the delete for the AA tree by converting to a 2-3 tree, should it be the same end result after converting back to AA tree?
John Heide
01:02:31
Oh I see my problem, I copied the tree down wrong, I had the 6 and 8 switched around
Bert Love
01:05:35
Should we be seeing the solution
Olayemi Oyindamola Ajayi
01:05:43
^
Rahul Khanna
01:05:44
We can’t see the solution
Hyen Jeong
01:06:05
no
Haroon Wardak
01:08:41
I thought the problem stated that we could assume all size values are valid for 4a
Hyen Jeong
01:09:19
do you give credits if the pseudocode is not necessarily identical but works?
Neehar Peri
01:09:51
Does the subtree of a node p contain p?
Afe Addeh
01:10:13
for 4a I believe on piazza it was said that all the sizes will be valid so we don't have to check if a node is null
Haroon Wardak
01:10:30
^
Hyen Jeong
01:11:30
to simplify the pseudocode, I just stated "p.size" instead of doing "size(p)". Is that wrong?
Shannen Lam
01:12:24
size() is a function he wrote to account for checking the size of something that's null
Hyen Jeong
01:13:21
I see
Afe Addeh
01:15:07
^ I misunderstood that too
Sonya Rumenova Radichkova
01:15:53
If we didn’t initially do the whole size function/null check for size, would our next problems also get points off?
Sonya Rumenova Radichkova
01:17:15
(I just assumed from the question that size was this int field that would always have a value)
William Cao
01:20:14
proof by induction?
Jordan Foster
01:21:56
Can’t we also go from top down for 6a
Xinyi Shi
01:22:37
just to verify, we can and should submit the exam multiple times during the 2 hour window?
Samantha Tang
01:22:46
Say we are studying Thursday, can we still raise general questions on Piazza? Or do you still want private in case it’s on the exam and we didnt know that
William Cao
01:23:37
you can make piazza private
William Cao
01:23:38
only
Yaeji Shin
01:23:49
if we resubmit, do we have to re-upload everything on exam page or would previous uploads be there?
William Cao
01:25:29
Thanks!
