Friends welcomed when new data structures and algorithm in Georgia girls it is really you trends in this race. Will discuss our reversals in the long list and your friends. Suppose your littlest bit north say an egg 111 and we throw out this link list as in book. So after Syverson the link list because something is 11:01 it and so it reverses the list. So here 10 8 1 11 gets reversed and becomes 11 11 1 and 2 Lexie's Let's go through them. So here is a singly linked list and for North Sea and it won 11 and bedhead points to the first node to reverse in single Englis. Here's the algorithm. So we'll see how this algorithm makes this thing relentless. So the first level is the vision where we will create a listener by the name current and the value of her sandwich. So she currently had burns the first nor so similar the can and will point to the first note which is 10 and moving and then we'll create one more note which will point to null. So the name of this note would be previous Moynahan will create a node by the name next and will assign a null value for. So the basic idea of the algorithm is to traverse each node one by one and then apply some logic to reverse the position of the north. So in order to traverse each node one by one will apply a while. And in my level blizzard condition then current becomes null. Well I read this well. So here we see this current point too fast nor image not null. So this why executes and then what we do here is see this next functional. So we'll assign the currants next to it. So if you see current parts of the first node in its next front to the second or so we'll assign Garance next when you go the next door. So then it becomes something like this moving. Here you see the current next which at this point the end points the center north and previous find to the null. So our idea is to break this pundit and provide a new look. So what we have done is you cut and or next and will assign an elderly to it. So it will look something like this. Door previous nor will assign a value of which current or so it will be the first nor so it will become something like this morning. And then to simply Kernville Sanden value you were just in the next socket the first iteration yet is this north. It would look something like this. So this is the condition with the first novel again and secure the way I look and we'll see the current is equal to a lot more. So current point of the SEC are not just not. So this is of course they will perform the same steps. So here will provide the next failure to the next node. So your next is that hard nor Willis and next Welcome to the next north and similarly to carve next will provide a venue which is present the previous show. So here if you see that cut and next part the point that are not so we'll remove this link and we'll assign it what the previous horse so your previous part of the first. So we'll do something like this. So the next now points to the previous which is the first node. So moving our to this previous Novellus and the Vellacott and so moving and not simply saying what are developers and then the next to the can and so the cut and crevices of the Turnour will trade the way I live and we check with the current is equal to the love. So your current ones that are not just North people do not so this louvers of course. And similarly Novelis and current NextRadio the next. So it will look something like this. And the next will assign to the previous. So it becomes something like this. We will make previous point to current and finally we'll make current to point to the value which next point is very devastating for the north. And again we check with the current is equal to or so its not a burden on sort of an exponential cut on snakes. So so your current Snax funds are not there for the next really pointing are not moving ahead and colorants
