thanks !

[@TeenyPort]

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

[@makima7457]

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?

[@sidtalks2885]

@@makima7457 Believe me , you won't need any of these

[@hen56349]

@@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.

[@rafiashan8389]

@@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.

[@Bladermishal10]

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

[@austecon6818]

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.

[@nadim379]

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

[@Brajgamer]

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.

[@svistetsky]

Once you've solved enough of each pattern, you can reduce any given problem to the basis (some "ideal", simple problem).

[@YashTrivedi-iq3ft]

Bro speaks in Lowercase

[@the-real-dr2050]

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

[@lakshmi8347]

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 🙏

[@avinashkumar3116]

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.

[@habibalnoman845]

happy to see you, love from Bangladesh ❤

[@Bladermishal10]

Are you a software engineer in Bangladesh?

[@BrownStain_Silver]

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.

[@anamikakumari3879]

It would be great if you could share curated questions list for each pattern for practice

[@anthonybustamante5736]

look up Neetcode

[@dasariasritha7974]

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

[@Shhhh-ni5jw]

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

[@rammuchhal3708]

How many problems you have practiced?

[@thomasthomas3655]

Me too

[@chandup832]

can you share list of problems in each pattern to practice? That would be very helpful, Thanks

[@navin_thomas]

Thanks for providing the advice regarding the bisect module functions.

[@045sunilkumar2]

Please tell us about how to start leetcode for beginners

[@J4RMAMS]

I love you Sahil!!! Your journey inspired me to apply for a masters in computer science at Northeastern University!!!

[@juq6971]

this video is only useful for those that have already solved enough of those Leetcode problems

[@jonathanjohnson2785]

Too valuable. Thanks Sahil❤

[@thanhn2001]

[@ranihirani]

I'm so gonna consume these patterns into my soul.

[@syedsaad4160]

Hashmap is pretty important too

How do you create such animations?

Greater explanation

[@ayushtiwari6473]

Prefix array, hashing are add-on

[@SDGful]

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

[@vishwaroop1431]

bro whats difference betn 2 pointer and a sliding window

[@shanthim2573]

Good effort bro

[@MADA_QWE]

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?

[@youtubeuserwhowatchesyoutube]

same bro same....i feel like iam working so hard for nothing🥲

[@anihadagali4725]

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).

[@CodingWorldHere]

Hard to digest in 8 minutes make detailed video.

[@mdyusufansari8897]

please make complete courses on devops, cloud computing.

[@Simple_OG]

Stop watching courses do something with yourself

[@carl.bergmann]

@@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.

[@pawelsubko7277]

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?

[@NatureNourisher]

Solve sudoku.. and other corelated ones.

[@madhvishrivastava3646]

Sure I will start solving now. Thanks alot

[@rahulkumar11a98]

Should we do DSA in JavaScript

[@nofeah89]

Can do in any language JS is popular because its the backbone of web

[@pawanterdal2261]

What about dynamic programming and graphs ?

[@suprakashghosh4224]

That's the remaining 20%

[@rishiraj2548]

Thanks

[@jotrades26]

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
