That's total 1411.63 minutes of quality content, 23.52 hours in total, great work!
Brother,I have started watching your lectures since my 2nd year starting,now I am in 3rd year,now I am easily understanding any recursion,dp,trees,linkedlists etc very easily and now I am getting an idea of how to do any problem because of you brother and I am solving those by your tricks and nice explanation.Thankyou soooooooooooooooooo much brother striver. Keep rocking............... From your brother.
The entire series has been absolutely phenomenal. You explained DP in the most intuitive and simple manner. Kudos!!
Thanks so much! You have helped me get over my fear of DP. Now most problems are a cake walk.
Congrats to everyone who successfully completed this playlist :)
Yes home boi :)
It was amazing experience 👏🎉
Now after completing this I have a question for you please reply is this playlist is completed or it is enough for placement
@@Ritik007A I have also completed this playlist, this is more than what is required. You can go for Aditya verma's playlist and that would suffice in most of the cases as far as placement is concerned. I've seen that one as well.
@@AbhishekYadav-rm4hw is it enough for internship preparation?
Listen Raj, i don't know will you read this comment or not, but as you are working days on ur job and night for us and bringing us this level of content specially freely on youtube, man , you are contributing a small role in making india a superpower, people will learn quick and will apply this knowledge to make indian IT community the best in future.
Hi striver😊, recently i started dp series and today finally completed it💪💪 My mother said who is this boy in red shirt you watch him everyday. Even your jacket is famous now, 😍Thank you for amazing series.👍❤❤
My mom was saying the same ❤❤
how much time did it take to complete brother
10 -15 DAYS ....
My mother also said the same thing :-)
@@steyn5723 you are legend. Keep it up .
ive finished the playlist today and i cannot thank you enough striver you made even the most complex problems seem easy and only a truly master of their craft can make anything they do seem simple. Not everyone can teach as good as you and im so blessed to have found your youtube. Take u forward is by far one of the best DSA channels outhere. and like always understood!
Great to hear!
Confidence ++ ;
Fear -- ;
Just completed the playlist, thank you so much for making this!! 🙌
cool
Watching this last video of the entire DP series has build a lot of confidence. At the same time w.r.t one of your SDE sheet related preparation video, you had said, "I played my own videos in 2X while preparing and went through all my notes each and every day!"
So, thanks for being utterly honest with the audience so that we also know that it isn't that easy that if you do it once you'll remember for life!
Thanks for the entire series and everything.
Extremely grateful. Kudos to you! :)
Hey Striver,
Just wanted to say a big thanks for the awesome DP playlist! It was seriously awesome and made dynamic programming feel like a breeze. You're the best!
Congrats to everyone who finished the playlist! 🍻
Hey
Since you've completed the playlist I just wanna know do the videos follow the sde sheet order and if any other resource do i have to look up on or any other advice u wanna give for a begineer.
Hi bhaiya , recently I got an offer from Amazon. Your videos have helped me a lot to prepare for DS algo questions , thanks a lot !
was there any system design or lld round, if yes, from where did you prepared them.
party de bhai.

@@kumarsamaksha7207 no no sometimes they do ask, if u went through interview experiences u will get to know
Understoood *56 !The dp playlist ended and so the fear of dynamic programming . What a batch in we are to be blessed with striver as teacher !!
Started this playlist on 1st Nov and today is 22nd Nov. I went from not even recognizing a DP problem or what DP is to now completely understanding the whole DP along with its intuition and logic building and coding it myself. This playlist will be more than sufficient to master DP. For anyone who want to start DP don't think twice just go for it.
bhai mai confused hu ki inse padhu dp ya aditya verma se...help krskte ho
@@thedarkknight1865 inse pado kafi acchi padaya hai inhone. Space optimization aditya verma ke Playlist me nahi milega par unka bhi tik hai. Mujhe inse ache se samaj me aya bas uthana kafi hai.

How long did it take to finish this whole series ?
Thanks for the DP playlist striver.
Your playlist is the most structured way to learn DP.
Amazing man and amazing series. I used to suck at dynamic programming and recursion so badly, but this series has really helped me a lot. Thanks a lot
Amazing Series! Thank you for such amazing content. Wrap up for the DP series! Really enjoyed every single one of your videos & your approach to the problems.
The Best playlist for DP to exist on youtube. Learnt a lot from this playlist. 🔥🔥🔥
brilliant buildup! I didn't need to go through the whole video. I understood what to do when I reached at 7:48. More power to you.
Finally Completed series !! Thank you so much Striver !! This is the first time I have completed any playlist !
WOAH WOAH!!! Completed the most amazing DP playlist.
25 days back i was not able to solve a single dp question, cut to today "ane do ane do, aur dp ke questions ane do"
All thanks to u striver bhai
Amazing work 🔥🔥🔥🔥
In jethalal style😂😂
You able to solve dp questions on codeforce?
@@pradhyumansinghmandloi8240 that is on different level. this playlist is for those who are beginners in dp and want to prepare dp for placements. This is definitely not even upto the level of medium problems on codeforces but this playlist lays a strong foundation for people who may in future do questions easily on codeforces.
Completed the playlist today. It boomed my confidence because by just reading the most of the DP problems I am getting the intuition to solve the problem. Your are the GOAT striver. Maybe someday will meet you. waiting for that day. ❤
Before starting DP it felt like it would be a very difficult topic, but now after reaching the end of playlist it seems so easy, all credit goes to you. Your explanation of each problem is mind-blowing!!.
Completed the full series with 56 "fully understand" messages 😊
Thanks striver for such a amazing dp series!! 🙏
Thankyou man, for letting me get over my fears of DP!
Truly the best teacher. Really grateful to you for your hardwork and dedication. Finally completed this playlist and feeling confident enough! Thank you once again🙏
No better feeling than this...completing this series does add much value..learnt a lot of concepts of DP and variations as well....well now i'm much confident on myself to approach and try to solve each and every DP problem....Thank you for inflicting such a confidence in me....
And as always Understood
Thanks a lot for this excellent playlist striver! I have completed this playlist, and am confident about dp. At the beginning, I used to be scared of the word dp, but now I have understood all the basics of this vast topic and I am sure, I will be able to approach dp problems without any fear now
Thank you so much for this playlist @striver sir! Outstanding DP playlist ! Looking forward to complete all of your videos
Completed this series. Now I am much confident on solving DP problems.
understood and also completed the entire dp series , when i started DS algo every senior of mine told me that DP is tough to understand and these type of things , but i can say because i followed your lecture it never felt tough to me also now i feel confident that i can now do any DS algo question ........ and again Thankyou very much
Your playlist made me so good in DP such that i was able to solve many of your playlist questions without seeing the solution. In this question i was able to solve this problem without using any extra space that too without seeing the solution. All thanks to your previous videos i can be able to solve lots of dp questions on my own
