// *******************************************************
// LinkedList = Nodes are in 2 parts (data + address)
// Nodes are in non-consecutive memory locations
// Elements are linked using pointers
// advantages?
// 1. Dynamic Data Structure (allocates needed memory while running)
// 2. Insertion and Deletion of Nodes is easy. O(1)
// 3. No/Low memory waste
// disadvantages?
// 1. Greater memory usage (additional pointer)
// 2. No random access of elements (no index [i])
// 3. Accessing/searching elements is more time consuming. O(n)
// uses?
// 1. implement Stacks/Queues
// 2. GPS navigation
// 3. music playlist
// *******************************************************

TL;DR
small data set: LinkedList = BAD
large data set + lots of searching: LinkedList = BAD
large data set + lots of inserting/deleting: LinkedList = GOOD
import java.util.LinkedList;
public class Main{

public static void main(String[] args) {

may i know why 1. implement Stacks/Queues
// 2. GPS navigation
// 3. music playlist
is more suitable to use linked list?

This channel doesn't have normal content.
rather masterpieces

[@leihan2670]

I just love the way you teach， straightforward， easy, and clear。 Lucky to have you in this world

[@deafprophets9009]

That was the most simple straightforward no bs explanation for a data structure ever. You make DS&A look approachable!! Thanks for the content 🙏

[@jaimuelsilva5016]

Your videos teach me more than my professor.

[@siphiweclintonmthebule6474]

More knowledge in a shorter period of time

[@marxLz]

they're really practical

[@Ryder-gd9tl]

seriously same lol, learned in 10 min what took my professor a 90min lecture

[@amaanshaikh6868]

True😹

[@joelikespotatoes8321]

Same here, I wish I could pinpoint why this is so common, honestly it's concerning that "professionals" are getting dunked on by youtube.

[@adityajain7486]

You are a god of programming, Thank you for making my life easier. you are way more better than my stupid college teachers.

[@marklaw3938]

What a godsend of a video. I'm crrently doing online CS 1103 course and literally the topic for this week is about linked lists. Thank you for this video. Your videos have truly helpful in my studies thus far.

[@BroCodez]

Awesome! Looks like I made this video just in time!
I'm glad they're helping!

[@DeveloperLewis]

Awesome, simple explanation covering LinkedList thanks

[@hillcountrydev]

Just found your channel. One of my fav dev channels on YT. Proud to call myself a bro 🤙🏼

[@Amir_Plays_non_stop]

Hahahaha never stop surprising me! Each video is literally blowing my mind, what a way of explaining! Keep it up!

[@fadethecreator]

Hey bro, could you please do one on singlys like using the linked list class. This is eternally helpful, though I’m struggling to find tutorials on youtube that cover anything like the ListNode class, so if you could that would be amazing because your videos are the best!

[@shivamjha5962]

A docx/pdf file of this courses source codes and notes will be really helpful...thanks for keeping this course free really means a lot!!

[@visna3319]

your videos make me LOOOVE coding!! never thought I would say that so THANK YOU 🙏🙏

[@brandonkruger9040]

We on a roll tonight! Thanks for sharing bro.

[@iRandroid]

Great as always

[@musicspirit7015]

Thank you very muchh! I've been struggling alot about linklist address pointers and arrays for so long , but i watched just 10 mins of yours and I now understand everything! Thanks again brooo T-T

[@muhammed5667]

Thanks for the concise explanation, I feel confident for my quiz!

[@sigmaxricky6411]

gave a like before watching coz i know it will be amazing as always

[@theuberman7170]

OMG right on time!! Are you reading our minds?

[@Wonder_Chariot]

I absolutely love the way bro introduces himself. i love you bro

[@user-pi1nr5uf7w]

Holy shit, that’s incredible man. I really like your tutorials

[@GrowthPulse509]

Pretty helpful thank you so much sir

[@RyanHurku]

it is unfair that this video only has 554 likes at the time of my viewing , you explained in under 15 minutes , what took my professor 3 hours and 2 slideshows

[@wolanus]

Great video, thanks!

[@mohdsaleh3516]

Thx Bro for all your videos, i love them all, plz finish as much as u canbon data structure, then plz java design patterns, generics, functional prog. in java (lambda expressions), and parallel programing. Anything you like...

[@aymanmouhcine5749]

Amazing explanation

[@dashunderscore7470]

thank you bro , loved it , its so detailed and wasy to understand

[@rahulmandal1380]

Hlw Bro Code!
Keep updating this playlist at regular intervals.
The way you explain is Awesome..
😊😊😊😊😀😀😀

[@BroCodez]

Thanks! I will!
Weekly is a good interval, these are tough topics to discuss 😅

[@ottttoooo]

Hey Bro, I just finished the java for beginners playlist, it was very well done btw! Prior to that, I had absolutely zero experience in coding, and that was a great start.
What would you recommend for me next? maybe specific projects I could work on to improve my skills? because I feel kinda lost now :D
Thank you!

[@B3Band]

I've been solving problems on leetcode and hackerrank
That's how I ended up here, because I've never heard of a linked list despite following Bro Code for like 3 months now

[@Lalogum]

better than all my prof. much love

Since the LinkedList can be used as a Stack and a queue, is there a really a need to use the Stack or Queue class in Java?

[@letampatrickbienwi4610]

A video on how to reverse a Linked List please. Btw love your videos 🙌

[@drunkpancakes6277]

Can you do some object oriented code for Java. Love your channel and need it to not fail my class. Threads and recursive methods and stuff 🥵🙈??

Bro, just what I nedded for a project!!!!
You are awesome sir.

Nice! I made it just in time then!

[@creampielover69]

So linked lists work sequentially, like memory cells in the RAM right?

[@achillesa5894]

The first 5 minutes of this explained it better than a year of university

[@gameGXT]

[@slavkomag]

Hey, Bro! Could you (or any other of you folks grasping big Oh notation) explain, why inserting and deleting is O(1) and not O(n)? Would'nt the algorithm need to traverse the nodes to find the appropriate place to change the addresses for the newly created element?

[@NikolasToCore]

I'm still learning, but i've also been thinking about this, and i think you're right. The time complexity of O(1) for deleting and adding data in a linked list is only at the beginning and end of the list, because there is no need to shift elements like in an array. However, the time complexity becomes linear, O(n), if the element is somewhere "inside" the list. Because linked lists do not have indexes (that's the whole point), the element you want to delete or change within a list has to be found first, and as i understand, it is done by traversing the list. You have to go through all the elements of the list until the end or until a matching element is found.
So the main advantage of linked lists over arrays is that they can shrink and grow faster if elements are added or deleted from the beginning or end of a list.

[@Iamfafafel]

@@NikolasToCorealso learning but I think deleting at end is O(n) not O(1) since you need to transverse through the whole thing to know where the new end is. Deleting at the beginning is definitely O(1) though
