Great Tutorial. Just want to add one thing. In bubble sort you can reduce the number of iterations of outer loop one time. It will perfectly work fine and will make the code more efficient. public static int [] BubbleSort (int [] arr){ int len = arr.length; int temp =0; for(int i=0;i
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
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.
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, 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.
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
Bro, I'm so happy you're channel is doing well. idk anyone else who can take DS/Algo and make it funny and interesting at the same time. But, I still want to know who Telusko is.
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 TH-cam for problem solving
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
16:27 array in java doesnt nesserily store in sequence because arrayb stored in heap memory which states that doesnt store sequencely to solve this issue java in array contains a reference variable and what you say is the case when we talk about c language it uses pointer to point a memory allocation of array
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
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.
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
if you have not started dsa yet this video is fine but otherwise its just waste of time to spend 5.5 hours move ahead if you have your basics clear already.
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
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...
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😊
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.

This is the course all the Java Devs were waiting for. Kudos Navin Sir 🎉
The best thing that happened to me on youtube so far is coming across this channel, truly a master piece!

Great Tutorial. Just want to add one thing. In bubble sort you can reduce the number of iterations of outer loop one time. It will perfectly work fine and will make the code more efficient.
public static int [] BubbleSort (int [] arr){

for(int i=0;i

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
