Good afternoon, doctor. The voice is muted.

Okay, thank you very much for letting me know. You should be able to hear me now. Okay. I'll

start a few minutes early just to discuss a few logistics things. So technically we

are somewhere here. I'll update this. This is the first time we run it. I didn't know

exactly when we are covering what, but we'll cover everything. Don't worry. We'll finish

off with sorting today. Searching, we briefly started already before Christmas. And then

next week we'll talk a little bit more about something more practical about version management,

Git, and so on. And then depending on the time that's left, we'll definitely discuss

trees and graphs to some degree and up to Dijkstra. And then we'll see if we can cover

this as well. This is something you can also look up yourself if you're interested. That's

basically how dictionaries work. But right now we'll see how far we come. And then we'll

probably be in the first week of February, which is the last week, where we shouldn't

do too much things anymore because the week after, 14th, I think, or 13th of February,

we'll have the exam. Okay. And speaking of which, I don't know if everybody has seen

this yet, but before Christmas I released this mock exam. There was some discussion

before that you can only do it once. I think I changed it now. The system is not so easy

to navigate. So I think what you can do now, if you have done it already once, is to delete

your pass and then redo it, something like that. Let me know if this works for you. This

was the only option I could find. My intention was really to take the configuration from the

actual exam system and reproduce it here as good as I could in that student system so that you have

the kind of experience you'll get during the real exam. But now you can redo them as often as you

like. Really, I know I'm not judging you if you just click through it and submit, then you have

zero points. That's totally fine. And if you really give it a go and try to get as many marks as

possible out of it, yes, great. It's not marked. It has no influence whatsoever on your exam. So

feel free to have a look at how the exam might be. The questions in the actual exam are, of course,

different questions, but in a kind of similar style. And all of these questions will be double

checked manually. So there is probably there's one error text in this mock exam, which doesn't

seem to work out that well. So all of that will be checked. Don't worry. Also the programming bits,

I think even the exam system gives you some weird feedback. If you submit something correct in a

kind of piece of code, it tells you it doesn't work or something like that. That will all be done

manually. The only things I think that are really easy to do automatically are multiple

choice questions and so on. So they are usually tame multiple choice questions. So it will tell

you how many answers, for example, will be possible if there's only one answer possible,

things like that. Okay. And I think there will be 30 something questions in the exam,

all very short questions, but a lot of them. So take your time and then you should be fine.

Okay. And this is where we are actually now, kind of around here, lecture 11.

I've here the slides still in week 10. Yeah, I need to reorganize this a little bit,

but the material is all there. Okay. Any questions about logistics? Yeah. In student exam.

So there is a spatial system, which is looks totally the same as student, but it's a, I don't

know, more secure and yeah, but you can log in as in student at that time. And then you'll have

only that exam option for you, which the exams you've signed off. Did anybody do this already

on student exam? And somebody here? No, nobody. Okay. So it's, it pretty much looks similar as

here, except that it's a disjoint system. Yeah. And then you have this as this test exercise in

there and then you click. So it likes to the mock exam. So the problem in the student, I

checking my Python. Can I use Python? It's an open book exam. You can use the internet. You can

use Wikipedia. If you're quick, you can use of course the lecture slides and everything. You can

use your own Jupyter notebook next to it to check. Yeah. You can ask check GPT to ask to write that

for you. You can do all of that. All of that is allowed. Yeah. So, so that's fine. Probably the

chat GPT version would not fit the bill for that specific question. So you need to at least update

it slightly. But, but all of that is totally fine. Yeah. Just don't do too many things. So without
