"Somebody please get this man a medal". He's been doing such a great job, from unknown times. Thank you Navin sir, you've helped us a lot
10 years in IT zero programming skills. Started learning coding and was looking for Data structures and Algorithms , and someone heard my prayers and google recommended this video. Thank you Navin sir.
In which domain you are working?
This is the course all the Java Devs were waiting for. Kudos Navin Sir 🎉
STILL I DIDN'T SEE FULL TUTORIAL BUT YES I CAN CONFIDENTLY SAY THAT, LAKHS OF PEOPLE WILL BE HELPFUL COZ OF THIS TUTORIAL... THANKS A ALOT NAVIN SIR, YOU ARE DOING GREAT WORK, 👍👍👍👍
i dont know java only python i know. will tthis be benificla for me
You are right!!
@@ranjansamant9841no
bhai java seekh le, nhi to DSA using python seekhle@@ranjansamant9841
I still wonder how this man is not awarded with the dronacharya award because if I were the president definetly I will honour him withthat prestigious award.I would really be thankful for your free service towards teaching us with one of the most demandable course.
The best thing that happened to me on youtube so far is coming across this channel, truly a master piece!
same i am so happy for this gentleman thanks a lot sir.
Navin sir giving tutorial free so teaching method is awesome so last bench student also will understand. 🙏🙏🙏🙏🙏🙏
those are greate video series which make me come back with Dev, I understand in detail what you are teaching, thank you Navin
I am doing Complete java course by watching your previous awesome video. That was amazing. Very helpful tutorial.
U will not believe i was look for ds in java 2-3 days before n confuse where to start i look for teluska but didnt have any update videos n look here it is ,thank you teluska
Thank you for this wonderful tutorial Telusko. I really loved how the way you explain.
Navin sir you beauty , Before this dsa i was watching your java course then after 4 weeks i started looking at opps then i realised its all are already cleard. The way you give real world examples are realy 👌👌👌 .Thank you sir.
Thank you so much sir, can't thank you enough. If you could please also upload the other algorithms as well they will be very useful!
Thank you navin sir🙏Really helpful. So easy to understand. Hats off to your great way of teaching😇😇
Thank you so much sir,🙏🙏🙏 for your deep explanation of DSA, this video was really helpful for me.🙏🙏
Thank you sir it's very useful for the interview and job purposes you are doing it for free thanks for understanding problems of the interview 😇❤️👍
Great job Navin sir, it's so helpful for the students and you are giving the best. Even the college lectures also not giving this much of clarity about DSA and how it's usefull
Thanks Navin, for wonderful video... 🎉 You have been my real mentor in Java
Can't imagine a perfect timing of this video ,, thanks sir❤
the best tutorial is by learning from the Pro. thanks sir Navin!
thank you, sir, for much needed simple understanding of DSA in Java, one more request sir please make a video on how to prepare for a Java interview for fresher or nearly 2 years of experience with which topics to cover and how much DSA and other advanced topics so as a beginner we focus on the main topic and help in an interview..thank you for helping us in this java journey.
sir, when i see you in person, i am going to kiss..no matter if anyone calls me gay 😂😂.. you are the best of best for teaching such concepts for free to students..this shows the passion you have towards yours teaching..thank you soo much once again...
A masterpiece is an explanation of outstanding skill.
Total video good sir but the way and technology used in the first 16 videos or upto linked list are amazing 😍
Thank you for helping me out brother! You are awesome! I hope to use this so I can relearn DSA.
Thank you very much sir, we need more videos about dsa
I am recently for searching for same concept in java......Thank You, I got it from my Favourite Channel
This is a quality content for DSA
GOAT of explaining programming.....Devudu sir meeru🙇♀
Great work sir, it's really helpful for people like me.
Amazing work and learning a lot from your tutorials.
Great Work! Really Helpful Thank you Naveen Sir.
Thank you so much Naveen sir,If you could please also upload the other algorithms as well they will be very useful.
been waiting for this!!!!!one of the best instructors ive had
Thank you so much for this
A combined course for these was needed❤
Thank you so much sir
I also waiting for this course 🥳👏
Great work!
I was just waiting for this course.
Thank you ❤
Thanks for making it so simple.
GREAT GREAT GREAT only 3 words I have. Thank you very much for the Video.
3 years working as software engineer and never taking any algo and datastructure course.
I must take it since my goal this year is MAANG
Bro I lots of love,the way you teach is awesome
Best explanation ever, thanks a lot!
Thanks teacher massive concept.
Grateful to you sir, right time got the right video from your side sir, it is very helpful to my placements sir ❤
I started loving DSA 😍😍🙌🙌
Tq for making this video, u r the best❤️❤️❤️❤️
Thank you sir this vedio is really helpful to learn DSA
i have one more suggestion, please daily solve some difficult hacker rank questions or make a series solving hacker rank or code chef etc from begginer to advanced level. There is very less content in RUclips for problem solving
Best lecture for someone who wants to revise DSA concepts
Where can i get full course for DSA in java? Including Graphs, DP etc.
@@DivineCodeMythologyalgorep dsa 31 vids
Hey, actually i do love the way you explain! Tnx for the free Video !
Thank you, sir, for making this video. It will be helpful for me.
This is such an awsome video.. Thanks
you are just great sir.❤
Most awaited course ❤
Helllo Naveen, thanks for the whole package it will be helpful. 👍🏻
great tutorial..i watched scaler video on DSA but i didn't like that..Your videos are good and animations are also awesome..Thank u so much from 🇳🇵I am feeling confident now😊
For dsa which programming language can be better for fresher either java or c++
So iam in first year of clg
54:25 mid = left + (right - left ) is correct math logic to get the correct result.
Love from Kolkata Navin sir ❤
Thanks for this tutorial sir can you make a video on backtracking and recursion in java
This is truly a master piece, I am able to understand data structures now.
I have one question on linkedlist:
When we delete an element from a Linkedlist, we are just changing its pointer, are we leaving cleanup to GC? or can we do it in the code itself ?
GC takes care of it.
Can you make a similar to this for other datastructures in java collections
Furthermore on concurrent data structures?
sir 15:34 since the integer is allocated two bytes of memory so the memory address should be 101,103,105...is thsi correct?
Thank you so much sirrrrrrr!!!!!!!
Really needed this ...
Thank You Sir..
This is a video I am waiting for and finally 🎊
amazing please sir can you recommend the best DSA and algorithm sheet to follow ?
Thanks Sir🙏
Thanks Telusko.
Hi Naveen,
Thanks for the great tutorial.I have one question in "inorderRec" method in Tree Implemantation.
How the root value available to this method "public void inOrderRec(Node root)",ofcourse we are passing inOrderRec(root);
for me its showing root=null,thats why its not going to show the final sorted values.
How can i get the root value to inorder traverse method...
thanks naveen very cool
clean and neat
Its good sir, i thought vedio is telugu by channel name. But its in English good work
Sir please provide notes ❤❤that will help us a lot
thank you
Thank you bro 🙏🙏🙏
Waiting for this one 🥲
Can you please also help with Design Patterns videos with Spring...
In stack, show method, it should get printed from top to bottom right?
Telsko,why don't you teach web development?
Most awaited content for aliens from Telusko
I love ur videos :)
If we add random values to array don't we need to check if they are in ascending order or. not??
Thank you sir
Hi, I'm a learner, but i have a question in show method of linkedList topic at 3:17:34, instead of checking node.next =! null, why not check node =! null and it will print all value. we need not need extra system.out.println to print the last node data after while loop. Please correct me if am wrong.
How can we restrict system.exit() called by third party library in Java 17+ without using security manager?
Life saver.
15:34 if each integer is taking two bytes of memory then how come the integer memory location is marked as 101,102 becasue it is occupying 2 bytes. so the memory alocation should be 101,103,105... sir which one is correct
Sir, please make tutorial video on JavaFx
I don't understand, what makes difference using liked list or tree or quee....and arrayList....we can use arrayList also but how it will be as a topics in DSA ....I may be wrong but i don't understand how these concepts will be help 🙂🤔...if you have time can you please explain with small words by replying to this message
Sir youre father of java ❤
Any one suggest me next what I want to do for my better understanding or learning please 😊
I found a small mistake in the bubble sort alg
the Correct code is
The code is in Kotlin :
private fun bubbleSort(list: Array) {
var temp: Int
for (i in 0 until list.size - 1) {
for (j in 0 until list.size - i - 1) {
if (list[j] > list[j + 1]) {
temp = list[j + 1]
list[j + 1] = list[j]
list[j] = temp
}
}
}
println(list.joinToString())
}
The mistake is in the first loop, the last iteration is unnecessary so it need to be removed
thank you for content ! can u share notes for the same
Is data structures and algorithm concepts the same for Java and Python? If I go through this video, do I have to go through data structures and algorithms in Python as well? A suggestion can help me.
Yes, the fundamental concepts of data structures and algorithms are almost same across all programming languages. The core ideas of algorithms such as sorting, searching, and various data structures like arrays, linked lists, trees, etc., are not at all any language specific.
However, there are syntax differences, and built-in functions or libraries that you might use to implement certain algorithms or data structures are quite different for each language.
So, I think you need to go through the with the implementation of those algorithms in python for handy experience.
@@AbhinavRaj_P Thanks for the information brother!
❤❤love you sir
perfect
Sorry sir,
Has anyone realised that sir are looking like Bhupendra Jogi 😄
BTW love you Sir ❤
Please upload the courses for React and node js.
DSA is all about building logic, not just viewing videos. Please don't waste time on a 5-hour video. In my experience, it takes around 8 months to 1.2 years to master DSA in Java. However, it's important to note that DSA is not just about learning specific algorithms and data structures. It's also about learning how to approach problems and write code efficiently. Therefore, it's crucial to understand the fundamental concepts and principles behind DSA. While this guy may teach DSA, you also need to know how to approach problems and write efficient code
why we shouldn't waste 5 hrs on this video when we have to waste 1.2 years!!! It's Does matter if we waste 5 hours it's Negligible in 1.2 years although Programming is dead in this AI Era. Why someone would Learn Programming in this Ai era when Ai is sufficient to do 40 people's work alone!!! Companies are shifting in Ai world to save money that's why all the layoff happens!!
@@iamnotfamous6591who said that programming is dead in this AI Era if you dont know programming you definitely will not be able to understand what code snippet has been provided by AI you need to know programming in order to explain AI what do you want. And this guy is spitting facts in order to improve in DSA you need to know how to approach problems rather than just implementing Algos and DS. DSA is about problem solving because it contains so much Discrete mathematical topics
@@immor8al808 Ai can Do everything because programmers are on their way to build a Ai Software engineers who can do everything. If some high level SE doesn't want that people should work with coding then why should students waste their time in this.......
@@iamnotfamous6591 Bro I can literally send you tons of screenshots where chatgpt failed to even understand the context of the problem not able to solve many of the problems where I even explained the context of the problem clearly. Even Ai's make tons of mistakes developers clearly mentions that Ai's can also make mistakes no Ai can replace developers
I will remember your words throughout my life , thankyou!!
