Describe a procedure for listing all the subsets of a finite set.

All right. So you were gonna write an algorithm? It's been taking a listed into Joseph. We just listed into juice be represented by a I here. I wouldn't have it wanted a tulip too. So we have n of them. And the idea is that we're taking starting yet the second element when it's attract the first, trying to find out what a two minus a one is. Don't give us some very some value, right? And we're gonna go ahead and say, OK, what is a three minus a two only up to a n minus A to the N minus one. Right. These are gonna give us incident value. Wanna check? We want return, which everyone knows is the largest. Maybe maybe our is the biggest. Then we would want that to be our output. So that's the idea. And so since we're working with a list, if you wanna call our procedure Max stiff here, you can call it certainly whatever you want. Uh, it's gonna take in some lists. It was gonna be these integers, right? 81 a two a lift to a n. And these are integers. And more importantly, we should also specify that we need. And to be greater than or equal to To write us a list of one, we can't actually take a difference. So the first thing we want to do is consider the case where there's just these two two elements. Right? So what would we do? What we would set our Max difference. Two a two minus a one. Okay, so now, now, if and for these, consider them as a very well being, I So if the suspect, I have more than three or more elements in the list. Okay, So maybe specify here that we actually want not just prayer than three, but it's gonna go from 3 to 2 end, right? So, four I equal to the number three, but also up to, uh, indigent. And we're gonna then set a new value. Right? So this is going to be I'm gonna set this new difference too. A three minus. Let's start with a three. Run is eight to inland. Dude. A a four months a three and a a five months before we can represent that, but I'm minus. Aye, aye. Minus one. Okay. They're gonna compare these two differences. We have our maximum, which was just said it the first difference possible. And then we'll compare future differences to that. And so, if we have is our Max difference is less than our current difference or reset our Mac difference to this new wonder into the larger difference of then we'll just say, Set our max. Def. Two, This other difference. We found it on the list that was larger. And then the important part here is that at the end, we want to return the max difference, right? We won't return the largest when we found. All right, then that is the

Okay, So here were describing an algorithm that will find our repeating introducing a list. Right? So let's just go ahead and call this procedure repeated something that explains what does and this procedure will take in a list of integers. So up to some n number of integers, I was gonna shortened integers two ends here. And of course, this will only work if there's at least one element in the list. Right? So we need and to be greater than or equal to one. And so this w slash just meets with. Additionally, it is a non decreasing list. So a one must be less than or equal to a two, which must be less than or equal to a three. How much must be less than equal to a four and so on sees the stipulations we have. And since we are treating a list of these numbers were going to initialize an empty set that we can add Thio. Additionally, we're gonna create an N plus one element to our list. Right? So all set a n plus one equal to a n this last moment in the list. Um, we're gonna subtract, attract one from it. So it's less than that. So you don't be confused here. And plus one is our sub script. Um, but then the ai n just the end is the sub script, and we're subtracting it. And so this By creating this last element, we do that due to the comparisons we're going to make. So, while investigating any element, we're going to compare it to both the previous and next element in the list. All right, so they have it listed things here. The problem is, once we get to the last element in the list, their ends up not being anything for us to compare it to. Okay, So where initialized We're just sort of creating something there that will Paris our cellist, um, in an appropriate way. Okay, so now that we have lived in that initialized these elements, we're going to run through the list, right? So for I that's gonna actually started thes second index right And does that because again, we're comparing to the previous previous items in the less sort of started it a two, and it's gonna run on the way to end. And if if the element we're currently investigating is equal to the previous one. It says. That's just checking to see if we have. If we're currently have a two, we're just seeing Haze. That is the thing before it also it too. Okay, that's that's not quite enough. Because if we had three twos, if all we did was check the previous one, we'll be adding to to our list of repeated elements twice, right? Both at the second time it occurs, and the third time it occurs so that make sure you only out it to our list once. We also want to check whether or not the next item is larger. Okay, so we represent that by saying air is less than a I plus one, right? This is it. This is why we had to do this initialization here in the second step. And if those both hold, then we want to add the element in question to our list. Right? So we'll take the list and said equal to itself Whatever is currently in there, plus aye aye. And then finally, we want to return on our list. We wantto see all the things that are repeated in our list that we at submitted in twos algorithm. So we want to return s. And that will complete

Okay, so for this problem, we wanna take a list of their input and just figure out how many of the introducing the list are Negatives will call this algorithm, count an egg for count. Negative. And our input is this list, right? So it's gonna be a list of numbers are in this case, it's into yours, and our list is going to be, uh, and elements long. Okay, These are integers, and it's also important to note that there should be at least ah, one element in the list. Okay, so not an empty list. What is the point here? Is that, uh, we're going to be counting something. And so to do that well, you want a counters will set K is our counter. I want to say equal to zero Rex. There might not be any negative numbers in the list. All right, then, if we let I be our index for the latest still safe for I mean, this is equal to one. So to start, and then it'll go up to end so equal toe I've up to and well say, if the element A I is less than zero. Well, then we want to add one to our counter. Right? So that will, well set k equal notice. Trying to add once will take whatever its current value is and add one to it. At the end of this, we will return kegs. That was what was counting are negative numbers. All right, So if we set a counter equal to zero here to start and then reiterate to the list of for every element in the list, if that element is less than zero, add one to the counter at the end of going to the entire list, return the counter.

All right. So here we want Thio describing algorithm that would take an input of integers and find the location of the last even into during the lists. We're gonna go ahead and just call this thing last even and stipulated by the question, is going to take as its input a list of n integers on. So there must be at least one of these images right specified. So there's gotta be at least one of the element in the list, and they are all into juice. Okay, So to do this, we're gonna just introduce variable will call it kay, and we're gonna set it equal to zero. Okay, that's gonna sort of keep track of the index value where even integers occur. Right? So then we just want to run through our list. So for being our index, I won't let it run from one the first element on the list to end being the last element in the list. And we will have a check each element for even this. So if if a eyes even that is, it's divisible by two, then we'll just set k equal to ay. And so as this thing runs through the list. Each time we find a new even number K gets updated with the index value of that number. Okay, we do this because we are interested in the location, not the value. Right? So otherwise, we would have said K equal today, I and once it's gone through the entire list that we just want to read urn. Okay, so this will give us the location of our last even value.
