People who would also love to have a competitive programming/dynamic programming course from harry bhai plz like this comment!
P.s ,Thankyou for your videos
Aayega bhai, sab aayega chahe der se hi sahi
aati h kya isko Dynamic Programming
@@DeepakKumar-yc9hr bhai kya bol the ho harry bhai ko competitive programming aati hai tabhi toh voh ye course leke aaye hai na aur aap aisa bol rhe ho.

yes bhai i want that ques solve hi nhi hte h CP ke😟
Bhaiya, I really like how you keep English subtitles there. I am from Nepal and I do understand Hindi language but if I don't understand some words in Hindi, I can easily see it from subtitles.❤️❤️❤️❤️ You are the greatest.thanks
The real life examples always boost up the concepts..even if its difficult.. Grateful to you that i learnt DSA from you!!!
Summary of video:
BigO(1): constant time to run algo.
BigO(n): linear time to run algo.
Mathematics definition of Big(O):O(n)orO(n^2)....
Industrial definition of BigO: order of
Graph of O(1) constant graph of k (constant y axis)
Graph of O(n): linearly increasing.

My parents was shoked that i learn c language in just 20-25 days
All because of you harry sir
Love ❤ from barnala, Punjab
Thanku so much❤🥳
@Meme Man hi brother.... C is basic language and I'm just 18y/o so it will be taught by our professors un future and as harry sir said, if you learn c then you 60% learn c++... That's why im learning it
I'm sry .. Learned it

Thank You Very Much Harry Sir
Hamare School ke sir kahte ise dekhkar ki yadi tumhe ab samajh nahi aaya to tumhe bramha ji bhi aakar nahi sikha sakte 😅
For the First time I have learned Time Complexity in such interesting way.It was boring when I had learnt Data structures and Algorithm.You are Awesome and Great
The most creative computer science teacher I've ever seen.🙌 Please keep on this revolution.
You have a gift for teaching. Way to go brother!!
awesome!!!...
too good...finally got a perfect data structure and algorithms tutorial to FOLLOW...
thank you so much...
your way is the Best way to explain dsa , keep going Harry!
Concept cleared ,thanks harry bhai u r genius. Your real life examples made to topic so easier to understand .Thanks to u
I cannot thank you enough Harry bhaiya. You really made it so easy. I tried watching several videos before this but no one can explain like you. Thank you so much.
Most awaited series is here🔥🔥
Plz include interview questions 😁
Big O(1) - time independent hai input=file (algo) to run ke liye ( 1gb file- 1tb file Time same consume)
Big O (n) - time dependent on input=file (algo) to run
( 259kb -T1; 1gb-T2 (T2>T1))
Your and mine name are same bro😁🙃
one of the best teacher on youtube for coding . keep going bhaiya ..hats off to u
You explained the 'Big O' chapter in cracking the coding interview gracefully...
Thank you👍
Not good enough
are you able to download the handwritten notes??
Most people use that example
Thank you so much sir. For this awesome lecture and notes🙏
I came to realize that this expiation to time complexity is way better than Apna College's course. And i have decided to move forward using this . Thanks Harry Bhai
Finally someone who can really teach the stuff in the most efficient and effective way.... thank you soo much sir
superb explanation. You explained this complex topic in a very simple way. Thanks a lot
Sir, please also make one video on the payment gateways as this question is also asked in the interview. I have searched everywhere but no one provides a genuine content like you. You are providing a great acumen to us and I am also learning more from your javascript videos.

I have started watching DS/A from so many other channels but they all make me sleep but the moment I click on your video I was smiling and learning side by side what a genius person you are and so young also definitely you'll become big name in future. I wanted to get in Microsoft or Google that's why I'm focusing on DS/A. If I get my dream job MY FIRST SALARY WILL BE YOURS lots of Love from Lucknow
Hi harry,
Do we calculate time complexity of in build function?
Eg:- in java we have string, collections
In string if we use length()
, substribg..
I wish to get teacher like you. You are greate bro, very good explaination. Love you bro...keep it up👍👍👍👍👍
I am a mechanical engineer but I have been watching your video series for the last 7 days more than 5 hours everyday 👍
Kis college se kar rahe ho
thanks bro ... i have seen three different videos and i didn't understood what they were saying. Yours was very easy to understand. It is difficult to understand a concept and trying to teach someone in such simple ways.
amazing explanation...agar iss course ki playlist bhi hoti to maja aa jata.......
Ekdum sahi bola Kishore bhai

Haa Shai baat hai yaar 😪😪
You are the legend bro !! Just amazing !!

Mind blowing way of teaching.
So much thank you sir 😊
Awesome way of explanation. Thanks!
Hi..
Really appreciate your all efforts...
I just wanna request you to make a vedio on cloud computing.
Like how different cloud computing is from programming..which is more simpler to learn..
Just a humble request
Thank you very much. Sir please upload Lectures of Competitive programming for also🙏
U re really appreciable god bless you sir ❤️
Thank you for this series...🙏
I liked your real world analogies. They added more colour to the lecture.
this is what i used to do in my 8th class in 2013, my friends used to bring pendrives and i used to go to my friends' home alongwith HDD, used to open their computer cabinet, it was a lot of fun, thos sweet child o' mine.
Mai isko refer kar dunga apne junior ko jo muje problem hua smajne me aaj video dekh kar laga kaas ye video pahle mil jata etna simple way smaj me aana koi v smaj le... thanks Harry bhai
You are clearing the complex concepts in a very easy way thanks alot for teaching amd sharing your valuable knowledge to us
When my school teachers give examples, I always like 🙄 its not matching to the topic (khi se khi tk match ni hora)
You always give great examples related to the problems.
Hello brother, I'm from South India. Your lectures are awesome. It will be very helpful if English subtitles are added. So that everyone can watch your videos. I have never seen such a UA-cam channel teaching and providing notes too. All the best for your upcoming videos brother.
