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 8. Sliding window: 0:17

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

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.

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

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 🙏

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.

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.

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

Bro speaks in Lowercase

More like 40%, to solve another 50% to be at the desired 90% you need only 35 more patterns.

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

happy to see you, love from Bangladesh ❤

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

Too valuable. Thanks Sahil❤

Thanks for useful content!!

People from India 🎉

As someone commented earlier - Bro talks in lowercase 🤣🤣🤣

Thanks for providing the advice regarding the bisect module functions.

Thank you such a great video that doesn't take 1 hour.

I am always looking for your new videos ❤

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

Thank you Sahil ❤

That was really insightful ❤

Please tell us about how to start leetcode for beginners

Love from IIT Delhi jwala hostel

Hashmap is pretty important too

Hard to digest in 8 minutes make detailed video.

Which is the best course to learn DSA and their time complexities?

Thank you❣

please make complete courses on devops, cloud computing.

I subscribed to the interviewmaster mailing list. But no mail is delivered.

Good effort bro

Thanks a lot.

Greater explanation

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

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?

Me after listening to him: may be bro is very serious person in life Me after seeing thumbnail: may be not 🤔

Thank you Sahil anna

Please make a video on Salesforce Developer path

Are you a front-end / back-end developer or something else?

thanks a lot

Great knowledgeable video❤

What about UnionFind? Is it in the topological sorting?

bro is like sidhi baat no bakwas

good video bro..could you please suggest me DSA course for golang

Can you please make video on Salesforce developer path.

Sor I want to know is currently there scope in the industry because there is massive layoff please help me I have to prepare.

Suprised DP patterns is not on the list.

Good for revision

i love your videos😍

Finally you've uploaded a video

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

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

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 ?

Thanks

Bro can u make a video on doing a project on git hub for beginners plss

я удивлён тем, что много чего из этого списка есть в ЕГЭ

Very good

The legend!

your voice awesome

Amazing

Sir I didn't understand leetcode problem what can do please help.

I want to be an AI engineer which topics should i learn durinh my BSC beside DSA

Which software do you use for animation?

can you please share tools used to create these content

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?

Bro speaks in lowercase

All this is good until DP and Graphs come into play :P

DP is no tmentioned?

Hi Sahil, can I know if your running any consultancy for outside India jobs of so can you provide me the details

I am bigger python can i join your course are not

Can you please tell how to improve logical and critical thinking skill??

What about dynamic programming and graphs ?

Subscribed but no email..

❤

Where is DP?

your rate of speech is a lit bit fast i couldn't get you so make it solw and improve credibility of your voice

where's dynamic programming? 💀

Sir Maine Ise kiya hai

Should we do DSA in JavaScript

I am a student of Kunal Kushwaha

How to build logic

Cool

Bhai sahil , aap thora dheere bola karo yaar... saans lo bich mein. Itna tez bolte ho matha ke upaar chala jata hai. Aap woh creator ho jisko 0.25x mein dekhna padta hai

People from india👇

People from Africa👇

good effort, on lighter side if you are mentioning heap for top k elements (and not quick select), you are a noob! :D

Funny thumbnail

sir is talking in lowercase

❤

Op

you Are going way too fast. slow down and take your time with explaining or showing samples. this not TikTok you have plenty of time bro
