Thank You
mam
i didn't understand inside addFirst method if( head == null)
here head where did it come from?
please hlp me out

This topic took me 2 days to understand nicely. Felt like a webseries. Thank you mam. Very engaging session.
Last few minutes and starting few minutes is a bonus knowledge for us.
Nice tutorial, within 48 min, got to know many of things, By which I became comfortable with linked list, Thanks Sarhda didi for making amazing explaination.
These videos makes more sense to me when I forget the concepts in the middle of a problem. Best teacher💕
es wali video ke home work question ke Ans bhej skti ho
I love this channel. You are doing a noble job here. There is an enormous learning here. Again thanks.
Very good idea of starting linked list before binary search.
Because if you study binary search first then during practising on leetcode or any platform
Usually public submitted their answers in advanced form which we are unable to understand.
These contents are awesome. It would better if you can add English subtitles for international students like me. Cheers from Sri Lanka
Mam when you smile while teaching is the best part of this video 😀😇
And your method of teaching is very good 👍
Thanks for the video. It would be great if you could make a video on how to add/delete a node from the middle
mem jab jab aapka lecture dekhta hoon mera self confidence gir jaata hai
but mem aapka concept high lvl hai
I am a python user but, I learn concepts of these data structures and algorithms from here, Your style of teaching is awsome, So Thank you very much,
Love from pakistan
I am a python user also
Same here bro ♥
Nice explanation with very ease. I have tried many videos for linked list but this is best video to learn linked list from scratch.
We need this similar course in c++
It's better than previous one
You can learn concept from here and watch source code in cpp course.
This course is almost language independent.
or you can refer to channel code help .......for DSA series with C++

@5:45 She actually means that time complexity to "get" an element by index is O(1). While time complexity to "search" an element in an ArrayList is O(n) which is same as of linked list since we iterate over the entire list to search for a particular element.
Thanks Rinki.... I was thiniking the same and you clarified it.

@@mdsarfarazalam8452 Sir "Node next" will take the reference of node upcoming nodes. In runtime polymorphism we take reference of base class and use constructor of child class
Thanku mam, first you created a base of what a LInkedList is by teaching to add delete the element from scratch and then next by collection framework thanks for the efforts......
Thankyou Ma'am for making it easy to understand.
Since morning I was stuck into this topic.
Onboarding to assignments now✈️
es wali video ke home work question ke Ans bhej skte ho
in the video she hasnt initialised the head variable, why is it not giving error?
Apki video dekhar me coding basic puri tarha se sekh gaya thank you 🥰
I got a little emotional such a simple explanation In my college the linked list had started before OOps and I understand nothing and this is first time got to know that there are 3 types of linked list Thank You Apna College
Great way of teaching. Touching the mind .
your way of teaching is so good that no-one can feel bored while watching your video.
Even our teachers was not able to explain like u..👌👍🏻👍🙏
06:07 Linked list is a data structure that consists of nodes linked together.
12:14 Linked list is a data structure that links different data together
18:21 Linked list is a data structure in which each element is connected to the next element through a chain of pointers.
24:28 Insertion and deletion operations are key in linked lists.
30:35 Traversal and manipulation of linked lists
36:42 Two key operations in Linked List are add and delete
42:49 Linked list operations in Java
48:50 Link list in Java can be used to add, remove, and traverse elements.

amazing lecture i have studied earlier but i always learn new things from your lectures
i have never been so grateful to understand hindi
2nd problem -- it,s note a proper solution but
try to solve the second problem ---
public class ll1 {
//linkedlist Node
static class Node {
int data;
Node next;
// method for to delete a nodes whose value is greater than given value
static ll.Node deletenodes(ll.Node head, int rem){
ll.Node temp,p=head;
if(head==null){
return null;
}
while(p!=null && p.data>rem){
temp =head;
head = head.next;
temp.next=null;
}
while(p.next!=null) {
if (p.next.data>rem) {
// Node p = head;
temp = p.next;
p.next = temp.next;
temp.next = null;
}
else
p = p.next;
}
return head;
}
//function to print linkedlist
static void displaylist(ll.Node head){
ll.Node temp = head;
while(temp!=null){
System.out.print(temp.data +" ");
temp = temp.next;
}
}
// utility function to crete a new node
static ll.Node newNode(int x){
ll.Node temp = new ll.Node();
temp.data = x;
temp.next = null;
return temp;
}
public static void main(String[] args) {
//start with the empty list
ll.Node head = newNode(1);
head.next = newNode(2);
head.next.next = newNode(3);
head.next.next.next = newNode(4);
head.next.next.next.next = newNode(5);
head.next.next.next.next.next = newNode(6);
head.next.next.next.next.next.next = newNode(7);
int rem = 4;
head = deletenodes(head,rem);
displaylist(head);
}
}
Excellent Teaching Skills. By the way, can't define that you are laughing or speaking by looking you. That's a compliment. :)
Best lecture in linked list
Awesome 👌 the way of your teaching is outstanding... I wathed this video yesterday ... today i code all the methods without revisit the video ...
there are many videos i watched to understand the LinkedList, but this is the best out of them.
Thank you didi you are the best teacher who clear my all doubts without asking it.❤
Gajab mam
Saara concept clear ho gaya
KOTI KOTI NAMAN HAI AAPKO
everytime i watch this video ... i learn a new thing
thanku dii and aman bhai
Who were thinking Node Head is not declared and why editor is not showing error 🤔🤔😊
Same here dude, I was thinking this whole time... it was frustrating !!!!1
@@mayankupadhyay4447 same here.. i was in great confusion😑
Did you figure out how to fix that?
@@eashitadhillon1577 just declare

Check out notes
Hii ,your session improve me in dry thinking, knowledge etc. Thank You , Miss
Hello Aman Bhaiya,
There are few more concepts that we need as in college as professional, if possible if you can make video on these concepts of Java:
Java API Packages
Multi threaded programming
Managing Error and Exception
Managing I/O Files
Java Collection
Applet Programming
AWT
Event Handling
JavaFX
JDBC
Java Networking
Thank You
Durga software se karlo
You can learn from Smart Programming
Abdul bari sir ke java course se kar sakte ho
In line no. 14, where did the "head" come from and what it's type
28:47
Wow nice timing di!!
I'm searching for this 😊👍
Thank you so much!!!
Hii
didi, i was need it with java because i am learning java for placement and you are giving java lacture and DSA using java. so thank and thanks apna college
Your concept is so clear. All the very best wishes Betaa..Jio jee bharke..Am so proud of you.. Dear viewer, do not miss this video..Aap bahat aage jaaoge betaa.. keep it up 👍👍👍👍

The best thing is to understand using diagrams.Thankyou
such a greate level explenation
i have tried to get it into my mind from last 4 to 5 days but not able to understand till watching before this video........ thank you so much......... i think best teacher in the coding era..... whose very much aware where students got stucked.... and knows very well how to get out of them..... again thank you so much..........
aapse sikne k baad dubara padne ki jarurat nhi .great
Mam really yrr aaj tk ek bhe lecture samaj me nahi aaya linked list kaa your way of teaching is so amazing from scratch 😍 . Full of full concept clear just keep it up ☺.
@7:40 time complexity to insert "at the start of linked list" is O(1) while the time complexity to insert at end of the list or in the middle of list is O(n) because first we have to traverse the list to reach that node after which we want to insert new node.
exactlyy ,
if you know i have one question how can we check for head ==null without declaring it to a node type t=21:21
@@anilptl she mentioned at last
Can u pls explain about asymptotic notation and time complexity. It will be helpful if u could do it.
Really Lovely Explaination ..............................
where the head node is declared in here?
I watched the starting of code and there is no head declared but then too its not throwing any errors how??
same doubt
Declared at 28:46
Time complexity for accessing array element is O(1) and for linear search it's O(n).
Masha'Allah bohot umda.
finally didi is back and firsttime i understand concept and some one say me where to practice progrming qp on linked list
Agar linkedlist pahle se tha to start main itna kyu karwaya interview ya placements main kaam aata hai kya
Thank did...hat's to u didi....when i was at your age not able to grasped such a valuable knowledge and presentation...👍👍🏻👌👌
Cpp wale me bht easily smjh aa gya tha 😄

Excellent explanation,very helpfull
Thanks
my face in whole video 😧😧 then the video came of last five minutes got me 😌😌
You are a very GOOD person and always RIGHT
The way of teaching the concepts is clear & excellent 👌
Thank a lot for this valuable video ♥ Helped me a lot !
Mam ek Question hai ki Array index hum ( Zero se hi kyu Start krte hai ) Mam Please Answer
Good and great teaching skill 😍

Great.... Easily Understand ✨
From starting i will thinking it very hard but when i complete this video i think it is not hard as compare to i think . Thanks to shradha didi
Thank you so much mam .I was searching for this kind of explanation and now I understand.God bless you 🙏
Train wala example for linked list is the best one. 👍
My all problems are solved by Mam Sharadha, Love from pakistan
your teaching skill is so good!
But I am struggling to understand Hindi!
You can add subtitle!
Good explanation but I'm sure no one can implement linkdelist in real-world . Can you please also explain with some custom classes ?
Sukriya didi kafi Acche se bataya appne is topic ko
Samaj nhi aya... Lekin sunka accha laga😊
after watching this video , I fall in love with LinkedList
LinkedList explained so nicely.. got this video thankfully, :)
Thank you maam it helped a lot
Thank you for explaining it very well and making it clear..
Most important topic in java...POINTERS ...Pls....upload a video on this.....it will be helpful for all
there are no pointers in java. They are in c.....
Exactly , no pointers in java
Java has reference instead of pointer
U r too good teacher..Thanku :)
Thank you so much 🔥🔥🔥
Maaaaam u kept video title java&DS but explained only java code..... there is no code of Linked list for DS
head is not declared initially it shows red line in my vs code ...!!!
shradha maam is the physicswallah of coding

great way of teaching thanks dear.
hi, wonderful playlist.....can someone please guide me with some explanation about "HEAD" & "NEXT" declared in node class
Thanku u so much mam for anonymous teaching..
Best teacher ever world
The name of the channel should be "Apni didi"
super the way you are teaching is very good
How no one is talking about the head implementation in the addFirst method.
Good efforts 👍
mam, please make sub-sections in the longer videos, easy to rewatch.
1 topic 1 video is always have good learning experience
More video means distraction
@@rajkumarmaurya9635 no i mean like time-stamps on same video.
