Wow this video just made me realize A.) how much I forgot since I graduated, and B.) how much I haven’t needed to remember any of this so far in my professional developer career
so you mean these doesn't apply to your working experience. I am a student and I saw some competition problems like these and couldn't solve some. Then I thought that what will I do when I got a job?
@@makima7457 no, your job doesn't require this. However, it just improves your understanding of coding overall. If you are very good at leetcode, then employers can be confident in you. It shows employers that you have the discipline t to learn any skills required for a job.
@@makima7457 These kind of problems improve our problem solving abilities. That's why we learn / practice these pattern. In professional career, there not many situations where you need to use these patterns as there are already templates given. We just need to know how to use them accordingly.
I am still under 200 problems solved but I think I'm already qualified enough to say that this video is exactly the advice I would give too. The 80/20 rule... that 8 patterns will help you solve about 70% of mediums with the caveat that you DEEPLY understand the patterns and all the possible subtle variations. The other 30% are either different algorithms, tricks / math knowledge, greedy algorithms or DP problems... but most DP problems can be solved well enough with DFS + top-down memoisation.
Its one thing to master solving these problems. But its completely different story when it comes to identify these patterns in real world problems or modelling real issues with these data structures.
I just discovered your channel after 4 months in a basic Python and intro to data science. During the course, I've written a few programs to automate tasks at work. I'm deciding where to go next and the most efficient way to get there. This channel is awesome! It has put so much into the right context to make the next decision.
Striver has already made series on each pattern with problems. Check it out on his channel #takeUforward, course name - Strivers A2Z DSA Course. He is the best.
Hi, I really admire your content which is unique and worth, could please make sure that after every new method maintain few seconds time so that we can process it. Actually your words have clarity only transition of topics need a little gap
Can you please tell me if it is important to slove competitive programming questions ? Is it important to my career. I am good at coding and problem solving but don't slove hard questions
Highly misleading, came to see patterns but saw generic DS& Algo script , patterns are there, what matters is the patterns that build from intuitions not concepts
@@Simple_OG I disagree, doing something yourself if good for reaching "depth" like a path in a DFS. Doing a course/reading a book is like a BFS in a given domain. It gives you the overview and wires the concepts together. So, you need both.
I am taking CS50, Introduction to Programming with Python. Sometimes, when I try to solve problems, I can't figure them out. I might understand the logic, but struggle with implementing it. After attempting to solve the problem myself, I often have to look at the solution. When I do, I understand it. Does this mean I'm a bad programmer, or that programming isn't for me?
It's always Ok to look at the solutions. But Make sure you understand the solution. But do revisit the problem the try solving it again, this time maybe chose a different language (any lang works, it's good to know more languages).
Sir, I am a data science enthusiast I have covered all the mathematics behind machine learning, practice the implementation and did same for deep learning also. I started NLP please guide me towards this role I want to get a good job this placement season it will start later this year kindly guide
please should learn DS and algo to build big stuff and give it to open-source problem with Indian developers learn DS just to crack interviews thats why there is no Indian big open source community which has build some extreme stuff like Database, streaming solution, or compilers or anything not even a framework

Brother you doing great job 👍 ... But can u suggest me best book fundamental of DSA stuffs in java
The link is not working....
1. 2 pointer: 6:18
2. Binary Tree BFS: 5:26
3. Topological Sort: 4:33
4. Binary Tree DFS: 3:39
5. Top K Elements: 2:45
6. Modified Binary Search: 1:35
7. Subset: 1:04

@@rafiashan8389exactly but then when you wanna change job this is the kind of questions they ask in interviews, hence why I am here xD

I need some help
Its one thing to master solving these problems. But its completely different story when it comes to identify these patterns in real world problems or modelling real issues with these data structures.
Once you've solved enough of each pattern, you can reduce any given problem to the basis (some "ideal", simple problem).
8. 0:16 Sliding Window Pattern
7. 1:02 Subset Pattern
6. 1:34 Modified Binary Search Pattern
5. 2:45 Top k Elements Pattern
4. 3:40 Binary Tree DFS Pattern
3. 3:34 Topological Sort Pattern
2. 5:25 Binary Tree BFS Pattern
1. 6:18 Two Pointer Pattern
Several great easy takeaways from this video and I’ve only watched it once. I’ll implement bisect left and right in swift now lol. Love it, thanks

happy to see you, love from Bangladesh ❤
Are you a software engineer in Bangladesh?
I practices a lot of leetcode but my brain feels frozen right now and I cannot write any code even if I know the approaxh
How many problems you have practiced?
Me too
This video is mind-blowing !!!
Sir, Why don't you start a series on each pattern???
It would be useful for everyone even though it is paid 🙏
Striver has already made series on each pattern with problems.
Check it out on his channel #takeUforward, course name - Strivers A2Z DSA Course.
He is the best.
can you share list of problems in each pattern to practice? That would be very helpful, Thanks
Life changing video ❤
Hi, I really admire your content which is unique and worth, could please make sure that after every new method maintain few seconds time so that we can process it. Actually your words have clarity only transition of topics need a little gap
It would be great if you could share curated questions list for each pattern for practice
look up Neetcode
I'm so gonna consume these patterns into my soul.
Thanks for useful content!!
Thanks for providing the advice regarding the bisect module functions.
Bro speaks in Lowercase
😂 dang I lol'd so hard. His chill is unbeatable yeah.
Too valuable. Thanks Sahil❤
Thank you such a great video that doesn't take 1 hour.
I love you Sahil!!! Your journey inspired me to apply for a masters in computer science at Northeastern University!!!
I am always looking for your new videos ❤
That was really insightful ❤
this video is only useful for those that have already solved enough of those Leetcode problems
Can you please tell me if it is important to slove competitive programming questions ? Is it important to my career. I am good at coding and problem solving but don't slove hard questions
How do you create such animations?
I feel he should have mentioned the 2 pointer pattern at the top as the first pattern
More like 40%, to solve another 50% to be at the desired 90% you need only 35 more patterns.
what are those patterns and where to know them from?
What are those 😊
As someone commented earlier - Bro talks in lowercase 🤣🤣🤣
Good effort bro
Greater explanation
Bro speaks in lowercase
Hashmap is pretty important too
Great knowledgeable video❤
You have to implement it too
Highly misleading, came to see patterns but saw generic DS& Algo script , patterns are there, what matters is the patterns that build from intuitions not concepts
Grow up kid
please make complete courses on devops, cloud computing.
Stop watching courses do something with yourself

Are you a front-end / back-end developer or something else?
Which is the best course to learn DSA and their time complexities?
Thank you Sahil ❤
I subscribed to the interviewmaster mailing list. But no mail is delivered.
Please make a video on Salesforce Developer path
Prefix array, hashing are add-on
How to learn to solve subset and substring problems? Can you please guide
Hard to digest in 8 minutes make detailed video.
Please tell us about how to start leetcode for beginners
good video bro..could you please suggest me DSA course for golang
Sir, I am a data science enthusiast I have covered all the mathematics behind machine learning, practice the implementation and did same for deep learning also.
I started NLP please guide me towards this role I want to get a good job this placement season it will start later this year kindly guide
Can you please tell how to improve logical and critical thinking skill??
Hai.you should solve sudoku and logical problems which are available free on internet
By practicing.
Hi Sahil...sometimes I feel difficulty in thinking logic...I think it will improve over time by solving many problems. I don't know if I am right ?
Solve sudoku.. and other corelated ones.
Sure I will start solving now. Thanks alot
Can you please make video on Salesforce developer path.
i love your videos😍
Suprised DP patterns is not on the list.
Nice video❤
Finally you've uploaded a video
please should learn DS and algo to build big stuff and give it to open-source problem with Indian developers learn DS just to crack interviews thats why there is no Indian big open source community which has build some extreme stuff like Database, streaming solution, or compilers or anything not even a framework
Which software do you use for animation?
Thanks a lot.
Thank you❣
People from India 🎉
isn't that all😂
can you please share tools used to create these content
bro whats difference betn 2 pointer and a sliding window
I can't think logic of an easy leetcode problems can't solve a single easy leetcode problem till now from 2 years I m learning 😖😖😖
Sor I want to know is currently there scope in the industry because there is massive layoff please help me I have to prepare.
Bro can u make a video on doing a project on git hub for beginners plss
Sir I didn't understand leetcode problem what can do please help.
Should we do DSA in JavaScript
Can do in any language JS is popular because its the backbone of web
я удивлён тем, что много чего из этого списка есть в ЕГЭ
Thank you.....🔥🔥🔥
you inspired me sahil. btw how did you get 300K package? is it your negotiation skills or due to COVID you got a high package? please tell me
What about UnionFind?
Is it in the topological sorting?
what no that's totally different
Valuable video
I want to be an AI engineer which topics should i learn durinh my BSC beside DSA
I am bigger python can i join your course are not
Love from IIT Delhi jwala hostel
Me after listening to him: may be bro is very serious person in life
Me after seeing thumbnail: may be not 🤔
But the patterns will have subpatterns
Where is DP?
Very good
What about dynamic programming and graphs ?
That's the remaining 20%
Good for revision
Subscribed but no email..
your voice awesome
The legend!
I am from a very small village in Bihar. I am 19 years old and I don't even know how to operate a computer. Can i became a good software engineer?
Yes
thanks a lot
Hi Sahil, can I know if your running any consultancy for outside India jobs of so can you provide me the details
Thank you Sir
All this is good until DP and Graphs come into play :P
bro is like sidhi baat no bakwas
DP is no tmentioned?
Thank you Sahil anna
Amazing

Didn’t know topological sort is important.
6:18
where's dynamic programming? 💀
Sir Maine Ise kiya hai
catcha is nt working
