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!

[@PoojaDutt]

Thanks so much! I appreciate the kind words 😀

[@davemerkury]

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!!!

[@PoojaDutt]

Thanks so much! I really appreciate that 😀

[@evansala7814]

This video was really well-produced and you used really great analogies in very approachable ways. Good work!

This is easily the best intro to DSA that i've ever seen. Great video Pooja!! And the sponsor isn't bad either 😉

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

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

[@supremely450]

Great high level overview of most common ds. Nice for refreshing and understang at a basic level.

[@Ryan-qu4vx]

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.

[@jovanaycart]

Love your videos! The animation and editing looks so good, and the content is so helpful.

[@tahmidamajumder5067]

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.

[@DineshGgoogle]

thanks learning for my day is from you. FYI : FIFO is mentioned as FEFO in the Queue chapter

[@Artofnatiee]

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!

[@vladimir0rus]

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.

Thank you Pooja. You made it so simple that's readily absorbed! ❤

[@anuragchakrabarty]

Man this is kind of lesson one needs truly, the principles of the data Structures were explained so clearly. Thank youu :)

[@alirezarezaei8624]

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.

[@adismahmic2685]

rThankyou!! A clear, well produced video is so refreshing !

[@cnkumar20]

Array is a tiny container or huge.. important characteristic can't be skipped is its of SAME TYPE

1:25 , comparing strings with == ? hmmm

[@wixse.quisee]

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

[@NRRRRRRRR898]

This is so helpful! Thank you. Can you do more videos like this ?

[@bhoot-eu1he]

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

[@AdrianWright-k3p]

6:51:- I can say "Ventriculocisternostomy", but I struggle with "is". Excellent video.

[@graziribeiros]

Which code editor are you using??

[@BilalKhan-sq2qj]

great introduction wowww, the examples were so helpful in order to understand the concepts, thank youuu so much!

[@vladimir0rus]

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.

[@Traveltheworldforfun]

It was really helpful and what a great way to explain.

[@WellActualllyyy]

what language is are you using in the array explanation ? it seems fairly easy to understand

[@glen9620]

Just one question : can we implement x ADT with x DS? Like stack with stack ?

[@neerajslab]

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.

[@julia_rodrigo]

This is such a creative video! xD thank you! I understand data structure more now

[@gopesh97]

Ther'es a reason why array indexing starts with 0, not a rule.

[@avinashgardasalgonquin4371]

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.

[@obviouslyblack]

1:12 Please correct me if I'm wrong because I don't have formal training in CS. I just kinda learn bits and pieces as I dicked around with coding. This is how I imagined it when I learned about pointers and addresses. If a guy name Bob has a home at an address, then the person living one house over is Bob's 1st neighbor, the person living 2 houses over is Bob's 2nd neighbor, etc. In a way, Bob is his 0-th neighbor. I thought that computers dealt with arrays in the same way. It will find an address in its memory to be a home for the 1st number in the array, then it will house the 2nd number as the 1st neighboring address, then the 3rd number as the 2nd neighboring address, etc.

[@jedi10101]

[@davem-1944]

[@PoojaDutt]

[@bwalyajunior613]

[@taniaa9248]

It's a crucial phase for your channel's growth Pooja, try decreasing ads.

[@God0f0dd]

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.
