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.
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!
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
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
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!
Thanks for sharing your knowledge!! I really appreciate your teaching style! I process info differently than most... so, the visual aspects & examples really help make this info easier to grasp! Thanks!!👏🏼🎉🧡😁
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.

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”

@@flow5718 No worries.... the people who conceived Python and JS were obviously shy of any formal education as well.
Short, no BS. That's why I love you and I'm here. Thanks Aaron!
Why do RUclips 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. RUclipsrs 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😐
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!!
The editing really stood out in this video, great work!

dude!!! that's a leap in video editing, that blow my mind, is amazing!!! and as always you help me alot!!! ty so much!!
this is hands-down the best data structure explanation that I ever saw on the internet
Wow.
This was incredibly visually pleasing and also interestingly presented,
I'm subscribing.
Keep it up!

Your channel is a gem, i'm so glad that i've found It.
Dude. Never stop making your videos. You are clear, concise, to the point and you have clear thought processes.
Good work, subscribed. Thanks!
Love the visual explanations, helped me clear some doubts!
The shortest, quickest and most enjoyable tutorial on data structures I have seen in my life. Excellent video. Kudos!
