Top 5 Data Structures they asked me in 127 interviews

1. How to learn Data Structures and Algorithms?
2. The best course to learn Data Structures and Algorithms in Java and Python
3. How to crack coding interview?
4. How to use Leetcode effectively?
I will answer all these questions in this video.

After watching and listening to countless youtubers, I can say you provide the most relevant, practical, effective, articulate and to the point videos that people really need. I really enjoy watching your videos and I have learnt a lot too. Kudos to you!

[@stupidfrog]

Graphs are the best. It's usually pretty easy to recognize when you have a graph problem in front of you, so as long as you've memorized the graph algorithms, you should be fine. Stacks, on the other hand, are the worst. It can be pretty hard to recognize that you need to use a stack a lot of the times.

Is it necessary to learn implementing data structures from scratch? As there are many built-in data structure especially in Java language. Please answer Thanks

[@Sandeep-kl9hb]

[@Om-bn3xb]

Most of people suggest go with c++ or java for placements and Don't go with python What's your suggestion?

[@gsettu7255]

Python as more inbuilt functions and it's very easy to do what you think when it's so easy u don't build ur logical ability how does that works behind so writing the code from scratch and learning from c++ and java is that's why always preferred and resources for the dsa questions solution are flooded with only these two languages anyhow there is no harm in doing with python u can explore

[@newfaith912]

Learn one..... You will most likely fail to understand it. Than learn another one and again, most likely u will fail again, but when u come to your third you will begin to grasp what u like and how to get a job. Programming is not easy as it seems. AI can program but ai cant solve unique problems. Thats where u come in and thats what ppl play you to do.

[@rajmajumdar5253]

​@@gsettu7255 c++ also has STL and Java has Collections. So that way people can also not learn the basic way to implement these DS and use the built-in libraries of C++ and Java.

[@CaliburPANDAs]

what if you only know JS?

[@LolLol007]

You can use any language you're familiar with i think

[@chideraferdinand3168]

Stacks and queue were the easiest I learnt but I try to think of were I can apply them

[@fdg-rt2rk]

They're mostly used while developing system softwares. For example: Queue(FIFO principle) is used in messaging systems like rabbitmq . Queue is also uses in javascript event loop architecture

[@munib2023]

Is it necessary to implement every data structure from scratch according to your experience? Please answer

[@codr0514]

You should know how to implement some basic data structures like LinkedList(Singly & Doubly), Stack, Queue, Binary Tree, Trie, Graph, Heap. In most of the interviews you no need to implement Heap, but knowing it's algorithm is always better. Same with graph. Once you know the inner workings of these data structures then you will be better off to know when and where to use to these DS.

Sir i am your big fan. I am a Civil engineering student (1st year). But i am too much interested about programing and also i have a dream to be a programmer, and almost i am starting learn python because of your inspiration.But now it is very hard decesion for my carrier that would i continue both civil Engineering and programing or focus on just specific one?
