02:38 And how can we have a tail pointer?
For knowing this, look at the addToEmpty() [Named as circularSingly() in the last lecture] function of this lecture.
Notice these points :
1. addToEmpty() function is returning the Tail pointer!
How? how the function is returning the Tail pointer?
- Because that pointer's next part is pointing to the first node of the list, therefore, that pointer is Tail!
2. Thus, by the Tail pointer we can easily complete our tasks and reduce the time complexity.
And in this lecture, the addAtBeg() function is also returning the Tail pointer.
How or why?
- Because the pointer that it is returning whose next part is pointing to the first node of the list.

Thanks :)
I love Neso Academy.

Sir Ur content is very helpful
But plzz upload lectures regularly 🙏🙏....

[沼氨]

Impressive from the beginning to the end!
Thx U guys for providing a wonderful platform to learn ALL these amazing knowledges!!!

Exceelent sir, in this programme I have learned the importance of function, that we haven't work more on main function but we simply distribute our work in small small parts, this is one of my favourite Lecture, you are great sir

Dear Neso Academy , Please reply what is the difference between datastructures and advanced datastructures?

[NitinReddy-iwll]

Wrong, line number 38
Struct node * tail = head;

[devanshchauhan]

but pls upload how we take input from the user

[universalstarcpu]

In 11th line of prgrm there is malloc(sizeof(struck node))
What does malloc mean what does it do ?

[nageegundala]

Sir, can you give complet source code single Linked list, double linked list and circular linked list

[aramvijay]

what about the head pointer? newnode added at beginning, its address should be updated to head ?

[ashwathbb]

Sir here u take only one one node .if we have to insert node to more then one node I mean list ...how to insert to list using tail
.

[utkarshlath]

sir how to makes notes out of your videos ?are you providing one in your app?or do i take screenshot and make a pdf or handwritten?

[raimasoni]

realy helping can we have algorithm also ?

[tatsuyashiba]

Please upload trees🙏
My exam is from 28

[utkarshlath]

Sir please assure me, I am from NON- CS background.Is your content enough for gate cse?do i need to practise anything apart from previous years gate papers after fully understanding and memorising your content?

[shreepadabhat]

U didn't explained how to insert to circular linked list with more than 2 elements...

[aravindks]

newnode->link = tail->link;
tail->link = newnode;
this isn't work forme
but this works for me
newnode->link = head;
tail->link = newnode;
head = newnode;
can anyone say why didn't that works for me ?
