@@GagandeepSingh-db8eh the discount is only for the first 20 people unfortunately :/ but you can still check out neetcode!
Stack is Last in, first out (LIFO). Queue is first in, first out (FIFO).
This is really well done! I love the focus on concepts rather than just the “big-Oh” times. And the examples made it pretty clear on when they’re useful, so this was awesome!
Thanks so much! I appreciate the kind words 😀

This video was really well-produced and you used really great analogies in very approachable ways. Good work!
Thanks so much! 😀
Outstanding video @PoojaDutt!!!! By far, one of the best explanations of some of the common DSA's used in code on YT! Keep it up!!!
Thanks so much! I really appreciate that 😀
I have learnt a lot in last 15 minutes, than those tons of class room lectures. Thank you and God bless!
This is easily the best intro to DSA that i've ever seen. Great video Pooja!!
And the sponsor isn't bad either 😉
Thanks so much!! 🎉 haha, can’t argue with that - the sponsor is pretty cool 😎
the way she explained certain topics with ease 🤧
That's frustrating now 😂😂😂😂
@@sk-kr1uy cz u can't catch up with every helpful info she has provided. yea kinda frustrating i must say 🤣🤣🤣
WoW i haven't seen anyone explain Data structures so smooth , great work keep it up
Awesome, wish I had a lecturer like you in my college. We just got a mini DSA pack in this, thanks for the video. It would be great we get a whole DSA Playlist from you 🙏
Same here

Why 0's and 1's means
It represents +5 and -5 volt ...
Its like giving power and stopping power to the conductor....so in that way a set of 0s and 1s represents plus and 0
...0001 represents the bits
Great high level overview of most common ds. Nice for refreshing and understang at a basic level.
In javascript "arrays" are done with Typed Array magic class where you can only store numbers (they can be resizable).
And Array is actually a resizable "struct" (? or buffer I guess) of pointers that point each to their data, so the data of the whole Array is sparsely stored in memory.
You can also just make a binary ArrayBuffer and interpret it however you like.
Love your videos! The animation and editing looks so good, and the content is so helpful.
I was finding it harder to understand DS until I came across your video. Thank you for using such amazing daily life example to visualize all the concept.
thanks learning for my day is from you. FYI : FIFO is mentioned as FEFO in the Queue chapter
Man this is kind of lesson one needs truly, the principles of the data Structures were explained so clearly. Thank youu :)
Very good video, in case it hasn't been mentioned the reason 0 index is the default is because it allow you to do modular arithmetic on the indices. If you've ever had the pain of trying to do modular arithmetic on a base 1 language, first I'm sorry, second you will understand exactly why 0 is the default.
I'd like to note that "linked list" is kind of an umbrella term and nothing is stopping you from linking the nodes in it with 2 or 15 neighbours (though you might be running into graph or tree territory), creating vastly different performance considerations.
Amazing video Pooja!! I was fascinated by your analogies and examples really improved my understanding of the data structures. I am definitely checking out your video on algorithms next. Cheers!
Thank you Pooja.
You made it so simple that's readily absorbed!
❤
amazing course ...u revised me all datastracture majors that i learnt in university
rThankyou!! A clear, well produced video is so refreshing !
Woah, thank you so much!!!! I am currently taking DSA in school. This is a blessing.
You make it seem so easy - great video !
Awww thank you!!
that's a problem, right ?🤣
Well explained 🙂 Big thanks!
How beautifully and simply you've explained ☺ Amazing video Pooja👍
time 0:51 "the array size is fixed when it is created." this depends on the language you use in java Yes in javaScript No
An ArrayList is actually an array and the size is fixed, but we don't handle the resizing or ... The collection interface is handling it.
Thank you so much for this video, you explained everything so well and I appreciate the examples!
So glad it was helpful 😀
omg thank you so much!!!! didn't know that learning DSA was fun until now
Wow!
This video is really helpful !
Thank you soo much for making this kind of Introductory videos 🙏😁
Stunned by the simplicity of this video. A perfect video to start with! Kudos!
Thanks so much!!

@@PoojaDutt thank you.
Under the hood, ArrayList uses an array. This means that removing and inserting items has a large overhead from shifting all the other items around. For that reason, we should look to avoid this method if possible.

Ther'es a reason why array indexing starts with 0, not a rule.
Outstanding video, thank you so much for your explanation. Keep it up.
Wow loved this video! I made a career change to software development and I've a lot of stuff to learn, I'm working as a junior and I want to learn more about data structures and algorithms to get to the next level. This video is great introduction thanks❤
So glad the video was helpful! 😀
This is such a creative video! xD thank you! I understand data structure more now
This is so helpful! Thank you. Can you do more videos like this ?
can u cover graph and DP?
BTW: this video was very informative
great introduction wowww, the examples were so helpful in order to understand the concepts, thank youuu so much!
I Revised entire dataStructures in just 15min from this video .... thankyou miss @PoojaDutt🙂
I have learned so much by listening to your views.
Array is a tiny container or huge.. important characteristic can't be skipped is its of SAME TYPE
The array starts with 0 is because the index is an offset inside the array. If you need to access the very first element your offset should be 0.
Thats how I learned it. You gotta make real life examples of it. I used actual file folders to break down the different search algorithms
Im a seasoned SWE and all i can say is real solid!
LEFO???? Last In First Out, LIFO!
holy... FEFO... i'm bailing.
Great video! could you please explain difference between Data Structures and Collections? I am confused.
You just blown my mind after watching this you are miracle lady
It was really helpful and what a great way to explain.
I did it, I learned what an array is!
It's a crucial phase for your channel's growth Pooja, try decreasing ads.
Excellent video, your real dictionary paper atlas cover cracked me up!
I know why starting from 0 because it reduce one minus operation calculation each time when we finding index location of index find by base address and index*size of element but this index is come by relative index for find relative index we perform operations indexe - lower index, hear if lower index is 0 than we not need this - calculation because of this we start with 0
So..
First In First Out -> FIFO
Last In First Out -> LIFO
They're acronyms. There's no LEFO/FEFO. It's just that when some people pronounce the acronyms as a word, they make the 'I' sound like 'ee' rather than 'eye'
Also, I don't think many list implementations are using just singly linked lists these days. But I've also never written a line of Java, so I don't know.
It's also important to note that a family tree isn't actually a very good analog of a computer science tree. Generally CS trees have the constraint that any given node only has one parent, otherwise you get the more general data structure, a graph.
One more nit: a tree is not at all like a hashmap. Hash maps use a hashing function to determine a slot to store entries and then a secondary data structure to handle collisions. In fact, a hash map might end up being built of many trees! Trees are, rather, more general cases of lists in which a node can have any number of children, but may only have one parent.
I agree..think uve not learnt the fundamentals properly
what about FILO and LILO
jk
Omg you are so good in explaining these topics.
Wow! Love how well explained her videos are!
So much too learn with all the different programming languages, but this video has made things a little clearer when it comes to Data structures and Algorithm.
Thanks for the informative video!

6:51:- I can say "Ventriculocisternostomy", but I struggle with "is". Excellent video.
How you easily pronounced the word 06:50😵💫😵💫😵💫.
Btw it was really very helpful because no one explains in this easy way, they are trying to make it harder stuff. So thank you so much for this wonderful content.
my man "Renaldo" is the linked list goat 😭
Me panicking because I have DSA Class this coming fall 2023, and then seeing this. Thank you 🙏🏾. I love that you used Ghana 🇬🇭! That’s weee I was born!
Edit: Like if you feel the same way too.
You’ve got this!!!
GH to the world!!!🇬🇭
Love this!
Thanks Lucy!! 😀
Hi Pooja Dutt. I mentioned earlier in the wrong video to please make a video reviewing the zero to mastery bootcamp. Please I will like to see this review to know if I should or I shouldn't go for this bootcamp.
Great video, thanks a lot, and thanks for all the links. Best regards
Thanks a lot✨
It really helped me🌸🌸🌸
Pooja, I hit the subscribe button right after watching this video. Thanks for helping me understand data structures, I've been struggling to understand them for a while now.
More people are using apps during the interview, like Coding Interview Champ to get the answers and then explain the solution to the interviewer, wondering how the success rate really is
This is a very good lecture ma'am, Can you please tech us the whole DSA ?
You just earned a subscriber, this was really helpful
Oh wow, I am from Ghana, and currently studying in India.😊
I quickly understood the examples, because of the 'plates'. Thank you.
Glad it was easy to understand 😀
It was an amazing video, I would like to know more on how you edited the video. Liked all of it.
Yo did great with setting examples with those items. Keep it up
thanks for such a clear explanation
I love the content of your videos Pooja! so useful! :)
Which code editor are you using??
Loved that you made video so fast after discussion about dsa in last friday discord session🎉❤
Ahh you noticed!! 😀
@@PoojaDutt ah well I was there that day
I love pointers in Pascal.
4:51 no renaldo is harmed in this video 😂...by the way great introduction to DSA
Thank You Pooja 🙏🙏🙌🙌
Using java is the easy amateur mode. Why not all write all from scratch using C where you have zero native support
Awesome explanations ! Thanks ! ❤❤
No problem!!
Very helpful video pooja thank u so much 😊😊😊
This is the best foundation to become pro 💯. Kudos to pooja🙌
Hello, Love your video!! Btw, what kind of theme do you use in your code editor? It looks so pretty!!
can you please make a full playlist in data structures and algorithms
Great video! Super informative :D
Very useful information, specially for beginners 👏👏
Thanks!! Glad you liked it 😀
😮 thank you so much 👍👍
I loved ur explanations. Definitely subscribing!
Thank you 😀
damn you actually explained linked list better than my prof i did not understand it back then
Can someone explain why so many data structures and how they actually differ in real world?
I mean, imagine a linked list, I imagine you could do the same with a list. What's the tradeoff?
Wow great job 👍
To be honest, I would give this video thousands of likes.
Ahh thank you!
Give one more... Ie 1001.... Logically that gives like to this video 😂
what editing software you are using for editing your videos?
