Can you make a similar to this for other datastructures in java collections Furthermore on concurrent data structures?

[@trnqulizr1289]

Thanks Telusko.

[@codewithgk9974]

Helllo Naveen, thanks for the whole package it will be helpful. 👍🏻

[@rushabhgujarathi1075]

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 ?

[@okcomputer2112]

GC takes care of it.

[@milankbudha]

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😊

[@mamidisaikrishna8233]

For dsa which programming language can be better for fresher either java or c++ So iam in first year of clg

[@commenter9451]

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 KZbin for problem solving

sir 15:34 since the integer is allocated two bytes of memory so the memory address should be 101,103,105...is thsi correct?

Can you please also help with Design Patterns videos with Spring...

[@tallurivamsi6413]

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...

thank you for content ! can u share notes for the same

[@samahmahdi5511]

I love ur videos :)

[@lokeshrajan6522]

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

[@shafi1164]

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

[@SaiTeja-ht4do]

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.

[@AbhinavRaj_P]

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.

[@SaiTeja-ht4do]

@@AbhinavRaj_P Thanks for the information brother!

[@krishkhemani96]

If we add random values to array don't we need to check if they are in ascending order or. not??

[@sayafhameedsheikh]

❤❤love you sir

[@user-yh5rm8oc5x]

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

[@binzilav8659]

Finally!!

Sorry sir, Has anyone realised that sir are looking like Bhupendra Jogi 😄 BTW love you Sir ❤

[@sabarinathan9422]

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.

[@namitatare7423]

Hello Can you please post the same video but in Python?

[@ArunKumar-vd8zt]

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

[@iamnotfamous6591]

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!!

[@immor8al808]

​@@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

[@iamnotfamous6591]

@@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.......
