As a current JAVA software developer, I have not been using more than 10% of my thinking power, and I can guarantee you don't need to fully understand the shxt in this video to do coding. Since most people NEVER understand business logic/idea, and they don't even understand their own code. They just copy existing code, edit it, turn them to trash code that somehow pass QA testing and code review, and thus, the trash code is in production.
@@caojidan8913 maybe that is true in your environment but unfortunately that is not how you pass interview for a developer especially junior they expect you to know a lot for data structure and algorithms you do not need to know perfectly how they work in reality but theoretically with examples for sure it is mandatory.
@Jerry Grauert Can you explain how it's constant time to insert element into LinkedList because if I want to insert an element at middle of list then I would have to iterate over first n/2 elements right? So it would be O(n)
No, all you do it ‘disconnect’ the pointer between the two nodes you are inserting. Then you point the previous node to the inserted node, and point the inserted node to the next node. Insertions is always O(1).
They don't necessarily explain it better, but because your professors have already introduced you to the topic, it becomes way easier to digest the second time you encounter it through youtube.
Because universities usually aim to educate for research and academical careeers. Not nescessarly to match market demands of programmers. And professors are usually very academically merited but that won't guarantee a pedagogical skill. And youtubers are very pragmatic, explaining a specific topic in a specific context usually. And not always right either - in the sense that they tend to simplify or focus only on parts of interest. Neither is bad, but it's a little like comparing apples and pears, or something. Aaron does a very good job in opening up the world of getting software jobs "in the industry", at least from his poinr of view. And he's very good at explaining too. That's for sure.
Your videos on programming are some of the absolute best I’ve ever seen. Keep it up, I’ve referred so many noobs to these lately. Great paced explanations and visual aids. Top notch, really.
Your Awesome, I have a Master now working on my Ph.D. in DBA/Data Analytics with Certs in 8 Programming languages with repositories on GitHub BUT, I'm still not confident in this area of Data Structures/Algorithms. You have a new fan because I love your "Lay-Men" method of teaching.
Aaron jack, I swear watching this video from you has made me more passionate in Computer Science than any of my profs have (aside from a few), but even then you motivated me more
i saw this video a few months back and didn't understand anything except arrays and objects. now that i studies all these basic data structures i can appreciate you simple/straight to the point presentation. Thank you so much
Very good and concise explanations! Thank you. One note regarding arrays - the term "array" is used in different languages to represent two different things - a fixed size array (like in C) and a vector. A vector is basically an array you can add elements to, usually allocated on the heap (in C usually with malloc). A fixed-size array can reside in either stack, heap or data section. In the video you refer to both as "array", it can be good to clarify that while similar, these are usually considered two different data structures.
I just wanted to say that I've been watching your channel since your second or third video and you have come such a long way. I can tell you are much more comfortable in front of the camera and your videos seem much more natural. Anyways, great work and thanks for the amazing content!
I’ve done a little bit of most types of tech jobs (web programming, DevOps, Data Eng) and I’ve always been intimidated by these concepts. I’m faced with having to find a new job and it’s been a bit terrifying having to get out there again. I am enormously grateful that I ran across this channel. I wish all teachers were as talented as you are at delivering information. You’ve given me hope.
I miss algorithms so so much! This was a great reintroduction! Thanks! I want to find a good job that I can use all this in. Reminds me of the class that I took the first year in university. "Discrete Math". I was getting 35's, 45's the first half. Suddenly one day I was slapped with the realization that it was easy! Basically 2+2. It got into calculus and it was so simple to do calculus after this! I then went into programming classes and algorithms were just so fun! Pity that I didn't go right into the working world. I had a huge multi year hold and I have lost most of my grip. But you have just reignited my drive! Thank you!
I didnt completely understand this and I even bought your course knowing i didnt really understand this but I wanted to support you. After completing courses in html5 css and javascript I was getting things but they werent lining up. Everytime I've hit a wall though, I always just keep pushing and I found a udemy course on swift that really explains things crystal clear and at a great pace for beginner programmers. While its a great course, I think its my determination to continue to expose myself to this information even when i dont completely understand it yet is helping me out. Dont give up! and thank you Aaron for making such wonderful content!.
This is the best video on DS I have seen on internet in last 6 years. Very Comprehensive. If you make a course on DS and Algo, I will definitely buy that
Very well done. The clarity was on point and the examples were handled very well with just enough information for comprehension. Also, very good use of graphics to increase comprehension. Thanks!
One video, and I'm subbed. I appreciate the high-level explanation of these DS's, as I am a student. Also, I dig the subtleties and nuance of your design/imagery in your videos. Strong work, please keep it going!
Really great job! Quick and too the point! Would have been cool to have the big O notation for operations since you brought it up at the beginning, but maybe that is for another advanced video since this was aimed at not using as much jargon.
Hello Aaroon, You always publish great content. Very useful information, simply put, straight to the point , no bullshit. Your channel should have more thana million subs, but, I guess people have not found you yet. Most channels I have been to are full of 'unecessary' information. However, yours is as long as it should be and as short as possible. Thanks , your content is greatly appreciated.

Answer:
1) Linked lists,
2) Arrays,
3) Hash tables,
4) Stacks and queues,
5) Graphs and trees
But, what is the question?
thescales18 Is this Jeopardy? **What Are** “DATA STRUCTURES you MUST know”
@Jerry Grauert Can you explain how it's constant time to insert element into LinkedList because if I want to insert an element at middle of list then I would have to iterate over first n/2 elements right? So it would be O(n)
No, all you do it ‘disconnect’ the pointer between the two nodes you are inserting. Then you point the previous node to the inserted node, and point the inserted node to the next node.

@@flow5718 No worries.... the people who conceived Python and JS were obviously shy of any formal education as well.
this is hands-down the best data structure explanation that I ever saw on the internet
Why do UA-cam guys explain concepts so much better than university professors?
they were at the same point as we are now
University professors don't have to be good teachers to be professors. UA-camrs need to be really good and entertaining to get enough viewers.
They know what they are talking about ;) :D

i love the darkness, feels like a true programmer
Dunno about that, I was kinda waiting for him to pull out a bong at the end.
and no plant or guitar in the background... or even (oh my gosh) a black cat😐
The shortest, quickest and most enjoyable tutorial on data structures I have seen in my life. Excellent video. Kudos!
You are the best programming teacher I’ve ever seen. I LOVE how you state the pros and cons and reasoning behind things. Thank you so much!!
Short, no BS. That's why I love you and I'm here. Thanks Aaron!
Fire content ! ! !
I'm currently self studying all of these CS fundamentals.
you got this
u go for it bruh

Love the way this channel is headed, im noticing the increase in production quality. Liked and subscribed 👍
cheers, I won't lie this took forever to edit
Aaron your way of explaining concepts is very effective. I will recommend this to my friends as well.
Your editing skills are on point.
Great job, man! Keep it up.
Omg thank you! As someone who zones out a little at length explanation, this really helped.
Please make more videos like this. it was so much easy to understand.
the first video that actually made me understand it rly fast and easy. Keep it up mate
One of the best videos I have watched yet 💖 Thank you so much ✨🙏
This is perfect review video for data structure class. Thanks!
🙏
This is the best video on DS I have seen on internet in last 6 years. Very Comprehensive.
If you make a course on DS and Algo, I will definitely buy that
Outstanding info and video. Lots of useful info packed into 7 minutes. Bravo 🙌👏👏
this was amazing
figured i've worked with these already even tho I was scared of data structures.
Very well done. The clarity was on point and the examples were handled very well with just enough information for comprehension. Also, very good use of graphics to increase comprehension. Thanks!

Wow the density of information in this video is out of this world! Great work! Keep it up. I’ll keep watching and liking!
@0:38 What is a Data structure?
@1:30 Linked List
@2:16 Array
@3:13 Hash Table
@4:07 Stack + Queue
@5:04 Graphs + Trees
I learned bst within few seconds I guess. Please make a full course on Dara structures and algorithms. I'll buy it first.!!!
very helpful video for some revision before an interview. many thanks

Ahhh the .push() and .pop(), how you explained it was gold! Thank you for that! That was cool haha
Excellent clarifying video. Thank you!
Great job, it's really easy to understand your explanation
keep up the good work
You are my motivation to keep studying software development.Thanks!
Also, for students, your recommendations at the end were gold. Thanks man.
came to learn data structures stayed for awesome intro :)
Off topic but I love that you have puar - shopping spree playing in the back, I found that song last year and I was vibing so hard lmao
I first learned Data Structures back in 96.
Today you made me wish we had UA-cam back then and your amazing videos. Great job man.
Most value I've got out of a 7 min video today. Great job
Great explanation of the pros and cons without getting too complex. nice!
Nice job man. Did a great job describing those in an easy to understand manner.
This is really amazing. Explanation with real time example! Excellent
I commented on an older vid of yours and made some comments on your editing. Now I'm eating my words. Great content dude!
super cool video, lot of knowledge summarized in one 7 mins video. Congratulations on this m8!!
I hope all college Professors be the same like you! thank you so much for your great explanation.
Thanks for the breakdown
Aaron, your presentation and production had both really improved. Fantastic content.
Keep it up!
Good explanations. As a person getting familiar with data structures this was very good
So glad youre killing it man! This content is soooo great...I have never understood why people dont explain these concepts in such simple ways...

Wicked short, nicely done.🙂
Thx!
Wow amazing setup 😍
Explained at masterpiece level
Thanks a lot!🙏

Simply the best sir... well done and very well presented
Lovely explanation.. Few months back I also posted video on DS and Algo for my Hindi speaking viewers and they are loving it 😊
Great explanation Aaron!
wow, that was so dramatic. never knew I could feel so much learning about algorithms
Very good explanation with less time.
