The humor in this video is top tier and the fact that you’re delivering it with a straight face makes it even better
Thanks Kelly.
He has that deadpan humor, i like it
“If you didn’t do it in one hour - Stop solving and check how others solved this” this is the best advice on this topic for me!
It took me many months to realize this.
That's right. Trying to figure out the solution on your own by spending too many hours is not worth it.
I only spend 30 minutes on an average problem and then start searching for hints on Google.
Please don't look at the solution yet.
If you can't figure it out in 1 or 2 hours, start looking for solutions.
Try to understand them well and choose the best one.
Don't just copy and paste the answer. You'll gain little to nothing.
or leave it and try another one, sleep on the one that you couldn't solve.
Well, i just check how other solved it if i can't solve it in 10 minutes hahaha
@@sahilandsarra please.. I need to know. I almost solved this in about 2 hours. The last test case timed out. If I practise enough will I be a decent developer. I'm constantly afraid I'm being overpaid.
SUMMARY:
• Solve all 37 easy problems first and then move to medium and then difficult in the 150 top interview problems
• First try to think about the solution and then jumping into coding part. In interviews coding rarely takes 15 minutes of time but major part goes in thinking. It may take 100 questions to practice this or 500 for some.
• In interviews you are given 45 minutes to solve a question so even in practise, if you are not close to the solution in 1 hour then see the solution
• Check atleast top 3 solution by sorting by most votes because sometimes the top solution is not practical for the interviews.
• Try to understand the solution instead of memorizing it
• And go to the editor, try to write the solution on your own ,even if it is the exact same code that you just read and then re-do it after few days completely on your own
• Even if you did the question on your own, go read the others’ solutions to find an optimized solution. ( In sir’s opinion, if you wrote more than 20 lines of code for a question then there is a possibility of better existing solutions)
• If you can solve a medium leetcode problems in 30-35 minutes then you are ready to go as mostly coding interviews are 45 minutes long and you are given a medium level question from pov of leetcode.
Thanks for your efforts
The key takeaway for me in this video is to think first about the solution approach and then think how to code. Although I know this, and I try to think of an approach before coding, I still end up thinking about how I will code. This video was a reminder about keep focusing on the approach first. I am a beginner coder, and it gives me immense relief to hear from you that with practice, I'll be able to differentiate between the two. Thanks for this gem of a video! Saving it 🙏🏻
It took me quite a few years to slowly accept the fact that if you really want to learn something deeply then you have to swallow your ego and start from the beginning; and to undertand that it's gonna take time, at least months if not years, so don't beat yourself up for feeling stupid.
So simple idea but in today's fast-paced world one might get frustrated with even the smallest of failures.
Keep going. In 10 years it doesn't matter if it took you 3 months or a year to ace a coding interview (or whateber you're working on).
Most people think short term. Thanks for sharing your wisdom. We need it 👍
so true, the world of instant gratification is making it harder for people to really invest in themselves.
@@viky293 True. It is why parents need to teach kids to read good qualities of books, debate skills with others, analyze our society and social issues, Math and English, etc. In the era of Tickok and Instagram, many young people are eager for something instant and pleasant. However, in the programming world, it doesn't work at all. We constantly need to learn from others, correct ourselves, and think deeply.. Hardship wins..
I spent 1+ years and solved 600 still I feel stupid
spot on. Ego is the #1 enemy at the beginning
What set your content apart is your honesty. Everything you said make sense unlike other UA-camrs. Keep it up ❤
YEAH u r right..
Thanks ❤️
Its just hard to believe that you actually sat there for six hours trying to figure out this simple problem. And additionally didnt even understood the solution after a hour.
Agreed
@@hjtvgfhjtghvfg5919 Nothing is hard about it when you don't understand it, in terms of code for beginners especially this is true.
This is what most of us need, not the person who always knew what is the path and what needs to be done, but the person who was left alone in the darkness and had to struggle to find the path to the victory.
I can totally relate with you I am in the same struggling phase as you were in the beginning of your journey. Every time I watch you I feel like if he can do it I can do it too.
Thanks Ritik. Struggle when done right is very important to grow. Only time I grew in life was during my struggle phases. Good luck Struggling 👍
क्या आप अधिक विस्तार से उत्तर दे सकते हैं?
Relatable
How you doing now in your journey ?
But the person who was left alone in the darkness and had to struggle to find the path…
These words hit hard atm…
I think one of the reasons people love your content is because you are so honest about your journey
I always hated coding but not slowly slowly building habits to learn it in an enjoyable way and then also seeing your videos so I don't lose hope. Maybe today is not my time to shine but tomorrow will be. Never lose hope. Keep making videos.
This is the video that gave me the courage to start with the dreaded leetcode. This video had everything I needed. I finally have a game plan. Thanks a lot.
i am reALLY SUPRISED how he softly and clearly spoke everything. i really liked the way he explained and I can relate this 100%
Thanks Sourabh!
Yes! I spent even days on just a single question just because I felt so bad I couldn't solve. For most, I eventually solve them but with worse time and space complexities. Thanks so much for your advice!
True
It is really surprising to realize how we all started in the same place. I remember struggling with even the first coding challenge and thinking whether there was something wrong with spending hours on the easiest problem and still not even understanding it. Today I can confidently say I have progressed a lot as a programmer, but videos like this help beginners to set realistic expectations and to continue pushing forward
What a superb video. This is the first guide on DSA that I find relatable and sensible.
That's the strategy I was seeking most of the time. Thank you for this 😇
lol I relate so much with that story in the beginning! I felt so bad about myself that I put off applying for an internship for 2+ years after I've already done all of my coursework for my Bachelor's degree, essentially dropping out.
It seemed to start when the only success stories that I ever heard from other students were that they had to submit over 200 applications before finally getting a response, and they already had a few substantial personal projects in their portfolio. Plus, they could solve these coding interview questions in 15 minutes for what would take me 6 hours.
Then I went to one of the in-person college presentation events and saw more capstones and internships that sound like something I could do than those that went over my head. Maybe it's just that those students aren't generally going around humble bragging to their friends in the room nearby to me. I don't even want to work for a FAANG company anyway. I want to have a healthy work life balance.
Idk what you going through, but keep working
You're godsend. I made my first leetcode submission today and you drop this ♥️
This is such a perfect timing Abdul! Good luck 👍

Finally, was waiting for this video...
"I recommend that if you are solving a problem which is outside these 150 problems, make sure that it’s your 151st problem." - the most importent point

I'm just now starting to prep for interviews later this year and hearing your journey is so similar to mine is really comforting. This is a great video, gonna give it a try! Thanks!
Best tutorial till date, its been years since I'm stuck with these languages and couldn't get a job but now I'm motivated again and sure that I'll bag one soon by following your routine practices.. thank you very much for this heck of a gem
Wish me luck guys
Good luck Randhir 👍
Exactly the THREE mistakes I'm taking currently! Lucky enough to be a beginner and see your video. Thanks!
I don’t often comment on videos but this was the perfect advice. I’ve had the same issues with trying to practice and this just makes sense. I’m acruelly excited to start studying again!
Thanks Ryan! Good luck 👍
Lucky enough to get this video as a recommendation in my YT feed!! You're amazing...You changed my approach of solving a problem..
I have been struggling in coding interviews..they are extremely depressing now... I hope I would see some positive changes after following your guidance..thank you so much🥺❤
Good luck Neha 👍
@@sahilandsarra Thanku sir!
@@sahilandsarraTo crack faang interviews, should i choose C++ or Python or Java. I know python basics and love it. Doing leetcode problems in Python will help or should i focus on C++/Java?
Your video quality is so amazing brother especially the way of conveying the message
Thanks Ragesh!!
You are the only honest UA-cam speaker who gives actually useful advice. I have been loving your videos, going to watch all of them soon. Love from Pakistan
Thanks Daniyal 🙏
Currently in my course I started 5 weeks ago and I'm having trouble learning Java in this time span. I know it takes time to learn, however having these assignments and due dates really effect my learning, being a slow learner. I've lost motivation but I will keep going
Thanks a tonne for keeping your promise as always by bringing up this video.... Appreciated
Thanks Dev.
Excellent video! Keep it coming and never stop! You are what we need.
A simple question. Coming from your Data Structures video which was your last video, you mentioned to take the free course by Coursera. I remember you mentioned that just Algorithm 1 is enough. So, can we start doing leetcode questions after finishing Algorithm 1?
Thanks! You need parts of Algorithms 2 like I mentioned in my DSA video.
@@sahilandsarra Got it! Thanks!
Thank you so much for this video. I'm in a situation where I have the IT industry experience of a decade but very bad at solving Leetcode problems. I was overwhelmed when I started to learn. I almost went into depression thinking I have made a very big mistake in my life by not keeping in touch with DSA. But, I have started to code 1 easy Leetcode problem everyday since this week. I hope I will be able to make some progress where I get some confidence that is expected out of my experience level.
Straight to the point. Great video! Glad I found you!
Thanks Jose
Thanks for the tips, I think one important point you missed about practicing is to go back to the problem after a few days to make sure you grasp the concept. And progressively increase the time since you last did it.
Good advice mate
Thank you bro.. I asked you to make video on leetcode preparation in previous video 👍🤝❤️
And I hope this video was helpful, Pranam!
I'm actually in the process of preparation for big tech and this video gives me really good advice. Thanks you my friend.
Good luck 👍
I cannot believe that it actually happened. I was thinking for a couple of days about what will be the best approach for solving problems on a recently bought course from Algoexpert. I was wondering about asking the creators of the course about the approach. Then I accidentally opened this video coz the title sounds interesting to me. I was looking for copper, but I found gold. Sharing your experience is nothing but amazing, I believe you helped a lot of future interviewees like me by publishing this video. So I wanna say - thank you!
I’m glad you found the video helpful. Thanks 🙏
I love this, I have been looking for a clear path on how to prepare. Thanks a lot
Glad you found it helpful 😀
The best content for someone who is changing his/her career to programming from something from non coding
I’m happy you found it useful. 😁
@@sahilandsarra you i am an agronomist trying to shift to programming wasted 6months and all my savings around 80k but your video made me realise like how dumb i was. But yeah i can start it in a proper way.
Weirdly enough, I've encountered some medium problems that were easier than easy problems. And I've tried some easy problems that utterly stumped me.
same here
very important information you are posting but in reality it is difficult to do all this without determination. Big thank you for all your effort.
That’s right! Good things don’t come easy because everybody wants to have them.
@@sahilandsarra yes you are right Sir & again hats off to your work!!
No bragging...direct to the point explanations👍🏻
I only did leetcode in college and honestly it's great to eval more junior level devs but seniors or even mid level are going to be doing much different kinds of problems
Hi guys...your content is amazing..i am following your steps seriously.. went through Algorithmic Part 1 Series by Robert Sedgewick .. started with solving the percolate problem and failed miserably. Then started listening his lecture on Dynamic Complexity and found it really interesting.... way more to go into the deeper insights of the course.. thanks for letting us know about great Content...
Great to see your progress, Shanmukha. Good luck 👍
@@sahilandsarra :)
@@sahilandsarra Hi Guys!! Wanted to update my progress
1. Learnt OOPS concepts in Java Programing as i wanted to explore core syntax experience.
2. Followed online edition of sedwick and solved intresting coding challenges daily and now comfortable with java.
3. Got deeper insight of inheritance, Polymorphysims, Encapsulations and exception Handling through HeadFirst Series
4. Started Practising Leetode EASY ARRAY PRBLEMS status 5/~2000
Waiting for your videos of learning intersting stuff
@@shanmukhasrinivas4883 well done bro..
Sharing your experience at the right time helps us a lot, keep going. I always support you.
Thanks Saravana!
Sir, I've watched so many videos but this one was the best so far! thanks man!
Thanks Kshitij 🙏
This might be the best video on how should one practice for interviews
TLDW; Algorithm:
0. Sort problems by difficulty level
1. Start solving new unsolved problem from lowest difficulty
2. IF solved OR (NOT solved AND time spent >= 1 hour): view best solutions
3. IF NOT solved: solve with reference of the above best solutions
4. IF new unsolved problem exists: repeat from step 1
Thanks for summarizing so well 🙏
even if you're starting your career or in the middle of it, no matter wherever you are, they ask you ds questions at every stage and this is by far the best answers you gave to the questions I had in my mind. Thanks
i love how calmly you explained each and every mistake and how to overcome them thanks alot got a ton of knowledge from you
Amazing video. I was just about to start using leetcode and this was what I needed
Love no waiting time and be authentic...great content
Thanks 🙏
This video is a gem 💎 . Crisp and practical
Thanks Aniruddh 🙏
Thank you ❤️ for sharing your experience.
Good luck for your future .
Keep moving forward ⏩👨💻.
Thanks Yash. Good luck to you too 👍
Hey Sahil, thank you so much for making this video. Really appreciate it
Thanks 🙏
very honest and amazing video !! totally relatable . On Leet Code, If we want to sort the easy problems further we can sort by acceptance % column, this helps a lot if you are beginner.
Thanks for this very helpful tip.
Been following a routine like this for last 2 months but i also make sure to solve one CP problem from codefoces in 1200-1800 range each day and in just 2 months i can tackle 2/3 medium level problems by myself
That’s great progress in 2 months. Good luck 👍
i don't know much about coding but the advice he is giving we can apply it on anything.thanks to you i now realized something.
Everything you say makes perfect sense! Thankyou!
Great to have guidance like you 😍
Thank you Harsh!
Great video Sahil. You have been a great inspiration to me... Keep your work on... And keep motivating others also.
Thanks Akash 🙏
Thanks for making the video and sharing the advise. It was very helpful. I found you might need to have the mic closer to you, your voice was a bit low and I hand to crank it up to hear you. Just a suggestion. Keep up the good work.
I love the subtle humor in this video. Great advice ! approaching the medium problems on leetcode is a common mistake I did too
If you cannot solve a problem, you feel sad. But if your friend solves the exact same problem in under 15 minutes, you are heartbroken.
Dude just won me over in that one sentence 😂👌❤️
We really appreciate making this vlog. I have a small request. What if you guys make a video about a list of impactful open-source projects that can get us a MAANG interview or how to choose remarkable projects to get interviews?
That’s a great idea Karna! We’ll keep it in mind for our next videos 😊
Thanks, this advice is really helpful tbh. I have had a couple of problems that maybe it takes me 3/4 hours on, and it kinda made me feel stuck about where to go.
Happy to help, Cameron 😀
when thinking of the solution "forget you know how to code". thank you, this just unlocked my brain!
Amazing tips! I would like to share another one: sort by acceptance rate for the easiest problems!
Btw. video production quality went up a lot 😮
Thanks for this very useful tip.
currently i have solved exactly 150 problems ,but they are random,
my suggestion : its different for everyone some get good at only 150, but for me i have set target of 1000 because i am from tier 3 and i am not as fast as these youtubers and there is no one ready to give me referral if i solve only 150 probs and also for me to become confident i have set atleast 1000 as goal, hope you all are doing good 😊
I talked about that at end of the video. Thanks for sharing.
Thanks for sharing man. I appreciate a lot this video!
Thanku so much for guiding 🙇♀️
This is really helping me out .
I usually waste 1-2 days in solving a single problem which wasted my lot of time and because of that I am not able to concentrate on other subjects .
Thanks 😊
As a senior engineer who has also spent lots of time practicing on LeetCode, These are really really good tips. Nice sharing.
Mathematicians spend the bare minimum learning a concept and spend most of their time solving problems. They "train" for speed and familiarity. If they can't solve a problem in 15 minutes, they immediately look up the solution. That's why so many mathematicians become great programmers.
I didn’t know this. Thanks for sharing 🙏
... what type of mathematicians are you talking about?
Lol! Not even close to being true. No serious mathematician "trains" for speed. Serious mathematicians do the opposite of this stupid statement - "Mathematicians spend the bare minimum learning a concept".
Look up the solution where?
Mathematicians are finding those solutions by working on them for far longer than 15minutes.
Also:
1) You never heard about mathematicians that don't become "great programmers".
2) Mathematicians are already preselected for the most intelligent and/or diligent people.
One of the most honest reviews I've ever seen. The "ego" part hits hard.
Thanks 🙏
I will call you "The Honest Bro". Man! Watched 2 videos and subscribed. Thanks a lot.
Thanks 🙏
Which language will be best for me as a beginner java or c++ ? I don't have any idea about coding or programming or language . I admitted in a collage in Information Technology branch recently . please suggest me 🙏
First C then java
Python or Julia.
Are you a human or robot..? Give some expression like sad, surprised, happy
I am curious about coding and I might start learning soon for fun this video was very good thank you for the insight.

Thanks Ishan 🙏
@@sahilandsarraabsolutely!! can you let us know how to crack systems design interview as well?
You are the on point and straight forward to the topic person and the best quality of your.
So request if you have time can you please start 1 JAVA programming series which covers all topics from beginner level to advance level and DSA.
Thanks for everything ❤️😊
Thanks! Making a good series is very time consuming and I don’t think it will help if I make “just another series”.
@@sahilandsarra okay sir no problem 👍🏽😊
I'd say it's easy to waste time on problem solving and not training your programming skills efficiently. I try to avoid hard questions since there's a huge risk the time will not be spent efficiently.
Most of the time should be spent on projects if your goal is to learn programming.
Thanks for sharing your thoughts 👍
Bingo.
Most of programming is not about making some specific operation a little more efficient by using several pointers, maps and linear algebra, but about writing code that fits into larger programs, fits edge cases and is easy to understand and change.
Cool video @Sahil bro !!
discovered your channel today, good work man ! Keep it up 🤟🤟
Thanks Jagpat! 🙏
one of the most awaited video....🙌🙌...learned a lot from this ...thanks Sahil🙏
Thanks 🙏
This video should be a manifesto. I should watch this for the next 6 months every week until I land a job at FAANG.
I mean, you answered a series of very important questions:
- How many leetcode problems you need to get good at DSA? 150.
- How to solve a leetcode problem? First think and talk about it and then code it.
- How do you think about solving the problem, if not code-like? Think about it logically, in general concepts.
- How long should you try to figure out the problem? Try to solve it in 45m-1h. Best to do it in 30-35m.
- What if you can't solve it in the given time? Read the best 3 leetcode solutions, if not so.
- What if you can solve it? Still read the best 3 solutions, because your solution might not be optimal.
Thanks for the video. You managed to answer all these questions in a little over 7 and a half minutes. I really liked it!
Thanks for summarizing ❤️
Sir,I am asking silly doubt but i hope you will answer me .
Currently I am learning DP and my on campus placement season will start from July 2023 .Can i master DSA for Campus placement till July? I am from tier one College (one of the top NIT)where many companies visits.
There’s no fixed timeline for it. Different people take different time.
Great great video! Exactly what I needed right now!👍
BROTHER, YOU ARE THE BEST!!! You oooh really helped me!! THANK YOU VERY MUCH!
Happy to help 😀
I like the way the content was delivered, others just try to sell it without supportive args..
Thanks Yash 🙏
My man, to point, loved it!
Thanks Akhil!
06:02 my biggest insight from the video - after understanding the solution, the most important thing is to write up the solution from scratch by myself. I will put this into practice. Thanks!
There is clarity in your content. Good keep it up. Also if I completely skip leetcode part what else should I do to become good in programming and get good job
I have already covered this in other videos.
Thanks for sharing ur luggage experiences and knowledge. Appreciated 🙏
agree that 150 is good to cover all the patterns. more is always helpful to perform better to get a higher compensation offer.
Love ❤ you sir you gave the right advice at the right time. I just starting DSA... ❤❤❤
thank you for your videos. They are very useful.
Grind 169 really helped me. I used Neetcode 150 to test myself without skipping the ones I already did.
What’s really important is your thought process. For harder questions your not going to magically come up with a solution. Learn how to derive results with your arsenal of algorithms you learnt.
Your content is brilliant!
Firstly solve everythign on paper, come up with a full solution, then interpret it to code!!! - The best advice that helped!!!
Along with all the rest!!!🤩😍😘
Thanks Dear for your honesty and sharing such a wonderful advise.
I’m glad you liked it. Thanks 🙏
Bro how calmly you are talking.. superbly amazing 🎉
thank you for your video. i not junior developer, so i think i know how to prepare. but your video show me why i everytime tired from continue solving. and in most, show me what i have done wrong. so i coming back to the easy questions again. and see how it's build piece by piece, and how one question prepare you to the next question. so i cannot jump immediately to the medium questions before i done all the steps before. and more important thing is to stop my ego for trying to solve questions 4 hours, and look at the discussions for learn. so thank you! :)
