Funny how i have to pay 10K for data structure course at my University and still learn nothing but here i understood everything for FREE. Thank you so much sir.
Can someone tell me what will happen if lets say the 1st element in the linked list is at address 100 so the integer part will take 100-103 address and the node part will take 104-107 and lets say the next element in the linked list is from address 110. Now I want to insert a new element at the second position but there is no address available for that (as the new element + the node will take 8 bytes but only 3 bytes are remaining) Then what will happen?
Hi Greg, Low level languages are machine language(instructions in binary) and assembly language. C is mostly called "mid-level language" because it gives a lot of low level control. But, generally the idea is that high level languages should give you a source code that should be portable to any architecture. Machine and assembly code work for a particular architecture only and need to be re-written if they need to be ported to other architecture.
I'm currently taking a data structures class. I've listened to my professor. I've read books. I've watched youTube videos. This video is by far the clearest, easiest to understand, most well put together lecture on linkedLists I have seen. You are very talented at explaining things.
Hi Mohan, Insertion at end will take O(n) because you will have to traverse the complete list to insert at end. Insertion at head will take O(1) ( constant time )
*My takeaways:* 1. Limitations of arrays 0:18 2. Linked list 7:43 3. Unlike an array, we can't access an element of a linked list in constant time O(1) 14:29 4. The time for accessing an element of a linked list is O(n), for inserting an element to a linked list is also O(n) 15:06 5. Benefits of linked list 16:29
My dream is to become a Software Engineer in the Bay Area, and as I sit through my first Data Structures and Algorithms course, and cringe at the explanations given by my professor and barely understand other concepts so far, this explanation of Linked Lists give me hope. Thank you so much for paying forward your knowledge, and presenting it in a way that I could understand it.
@@oscarwang7920 - Just keep learning, guys. You _will_ get there. Sometimes, a particular concept doesn't make proper sense until you understand other, related concepts, so you have to press on with a partial appreciation during the interim, but, your patience and dedication will pay off.

I cannot understand how anybody can disklike your videos. They are so well structured, considered and explained. Absolutely amazing. Dont give a .... on them who dislike your videos and keep up the good work.
Holy hell - I've looked through a lot of videos/courses and have yet to see an explanation of Data Structures that is this clear and intuitive. Seriously, thank you so much for this. The pictures and metaphors really makes concepts clear.
I love this tutorial but have not watched it yet because of my hearing-impairment i cant hear what is being in this video :( So please get me their subtitles so i can use them to add it on it using VLC player. Thank.

I usually dont like videos after I watch any video but this guy explained in such a way I could resist myself from liking it . I wish he may find peace wherever he is at
Dude you have no idea how much the scenarios helped. I wish my professor explained things like this instead of reading off of 90 powerpoint slides. I wrote it down in my notebook the same way you explained its really helped a lot.
+mycodeschool plz help, I don't understand when he says that insertion of a node will take O(n), howwww...........??? i think just two replacements of Link values happened so it shoud be O(2), right??? so confusing... :( Introduction to linked list

I study at one of the top CS universities in the world, but I still don't understand what my professor says. You explained WAY better than my university professor. Subscribed. Thanks a lot!
Enrolled in cs50 didn't understand anything on lecture about data structure because the lecture kind of just sweeped through lots of data structures without in depth explanation, but just the basic concepts of each, so now im struggling to do the assignment, and I saw a vid recommending your channel and I'm not dissapointed so far.. Thank you so much for this vids helps a lot
The day after tomorrow is my exam and I don't even knew why linked list is so important. This is the best video on Linked list. Nicely explained. Thank you very very much sir. God bless you...
Thanks Albert! Finally, someone just demystified the understanding of the Linkedlist. Important to understand Memory Bytes assignments to Nodes. Once you understand behind the scenes about the Memory Bytes Assignment for the Head Node and all the Nodes in the LinkedList, and then, the game is over, and you can be traverse the LinkedList as you want and delete any Node you want in the Linkedlist.
This actually helped me out quite a bit. Your videos have great quality and I appreciate the jump-cuts when you're drawing and the accurate subtitles. Thank you.
It's my first time to learn link lists during summer class which is only 6 weeks. I wish my professor began the class with an explanation or rather an illustration such as this one. After watching this I can clearly understand what link lists are all about. Thank you
Your content is on a different level than other youtubers who are making similar study content. When I start seeing your video I get assured in the beginning that I will understand the concept. Thanks for giving that confidence to your viewers through that content. cheers

Beautiful Explanation! I think this is the first time I have understood what linked lists are! Fluidic demonstration and wonderful manner of progressing on a topic.
I was struggling to get understand and how to implement this linked-list ..but this cleared my many concepts....May Allah show straight path to u brother.....
Jimmy Watson I would quote a dialogue from the famous movie Matrix, " What's real NEO? If real is something that you can see and feel and touch, then they simply are electrical signals generated by your brain." Allah, God or anything you want to name it is a question. A question, "What's the source of our creation?".. And as the Buddhist say, till the time you do not know the answer, you should say "I do not know".. I call Allah or God a seeking, an attempt to answer some unknowns, a submission to some higher energy in which we all dissolve. Whether its real or not is a conclusion and I cannot draw it. I am certainly accepting Rahim's wishes. And I am accepting your reasoning too. :)
What a fantastic video. I love how much there is to learn online these days. I need to learn more about data structures to be a better programmer and I also want to be prepared for when I eventually start my Bachelors level classes in my Computer Science degree. I saw the use of a LinkedBlockingQueue in a game programming series I'm going through which led me to Stacks and Queues, and then Linked List, and next is Blocking Queues
In C, structs are not created on heap or what we call dynamic memory. So, if you just create a Node normally , it will go on stack. Anything on stack is freed from memory once a function call finishes. You want to keep a node in memory till the time you want. So, you use malloc in C or new operator in C++. A node created using malloc has to be referenced through a pointer. That's why we have to use Node*. contd to part 2..
Very great , thank you sir Tommarow is my exam.. It helped me a lot because i understand the principle......,. Not like byhearting it....thank you.......sir
Explained brilliantly!Our college professors should teach like this.I was having a lot of troubles in understanding,feels like i am going on the right rack now.
if someone doesn't understand this ,then its better that you leave IT field and become something else!!!!!!!!! This is the best ever explanation possible.
Thank you for this explanation! I had some knowledge of how linked lists worked, but my knowledge was limited and convoluted. This video answered many of my questions. Thank you. Great video!
part 2... In Java, you can create a class class Node {int data; Node next; } and you will be good because classes in Java are automatically created on Heap (dynamic memory) and are referenced by variable name. To know more about stack and heap, see our series on pointers for a lesson on dynamic memory allocation.

plz help,
I don't understand when he says that insertion of a node will take O(n), howwww...........???
i think just two replacements of Link values happened so it shoud be O(2), right???
so confusing... :(
Introduction to linked list
muhammad waqas its not constant to say o(2) and there's no O(2) in Big O notation ... Also you don't know how many process you need to do (you don't know the linked list size ) So Its (n) processes ... I hope you got it :)
muhammad waqas Because it's worst case scenario, meaning you probably will have to travel n nodes to insert.
O(n) means that the order of operation is proportional to n (number of elements), and that in the worst case you'll have to traverse the entire list.
We have some important examples of data structure and linked list, you can visit tutorialgyan.com/what-is-linked-list-c-with-example/
