I do both, pay for BS degree in cs and watch these videos to learn on the side.
@@BlastinRope The Harsh Truth remains same in all places. without youtube we students will fail.
@@sayan_dasgupta how did the students managed before UA-cam then?
@@whannabi I can't even imagine. They most probably created the language we code in.
You have the skill of making most difficult problems easy and importing into human being's mind.
I have got to say, YK you are a genius, thank you for the entire playlist. Missed most parts of my semester after having had my eyes operated on and couldn't attend classes and after watching these videos, I can safely say I understand better than I would have even if I had attended the classes. Thanks YK, keep up the good work.
hey bru how are ur eyes feeling now , also how much did points did u recover and can u use computer normally now? i wanna do "lasik" but i am concerned about mine, PS: ik this is creepy but i just wanna know lmao :P
@@junaidahmed3981 same here. wanna know. have read about success stories but also heard that it can go wrong?
sir, please continue this. This seems to help a lot in building a way how to think about data structures and algorithms. you are a very good teacher. A lot of appreciation from India.
This is the coolest explanation of hashtable I've ever watched. Thank you!

finally found the best dsa series .
really appreciate man.
keep uploading
Finally one well made tutorial with dark background
I was just about to give up until I found your video. As someone new to programming, you have saved me from failing my Python and Java courses! Legend YK!!!
Hey, thank you, YK. You're king at this!
One of my favorite teacher ❤️

I’ve been searching (no pun intended) for a video explaining hash maps. Best one I’ve seen on UA-cam - thank you!
You explain so well
This is the best explanation on this subject matter on UA-cam
This bought clarity to one of the most basic data structures used. Thanks 🙂

Hi YK, my whole hearted thanks to you for making videos on this topics. I really enjoyed watching this content and grasp the knowledge. Really awesome!!. We really appreciate if you can make some more videos and package to cover main topics for the coding interview prep. Thanks in advance!!
you look so kind, like a kind oniichan or senpai helping us kohai. I appreciate you
You made data structures easy. Thank you❤️
Which channel
素晴らしいです!動画が分かりやすいし、YKの笑顔も癒せます😊
Two vids in a month!!!!! :)))))))))))))
I'm currently learning data structures and algorithms so it's a big help! Thanks!
Haha yes, I'll try to increase my frequency tho :P
And thank you!!

Please do more, you're my only hope 😁😁
Thanks soo much Dojooo because I have been taking Data structures in begin of this year and I was waitng for your perfect contents about data structure ... please keep going this seriess :)
Thanks a lot again
A bunch of love from myside bro u are amazing . Excellent explanation 🔥🔥👍👍👍
Hope you are doing great and hope we can see your update soon!
Well-explained. This is really helpful especially to beginners. Keep up the good work. :)
Hi. Does working as a programmer cause health problems due to too much sitting down near vision adaptation? Also what about carpel tunnel syndrome due to using the keyboard?
Great explanation. Just to add, In Java, HashMap is a popular Hash table implementation. There are more like Hashtable and ConcurrentHashMap but HashMap is the most common one.

Very good tutorial! Thank you
Great overview!
i'm here 15 minutes before the exam heh thanks man!
You Are the algorithm expert!!!
no need of algoexpert.io .... lol
I have been watching your channel for quite a while now and I love it!!!. Awesome and by the way did you know I also have a stuffed toy penguin that looks just like yours.😀😀
hey cs dojo, great content. Would you open up a series on building web app with python flask sometime in the future?
Hii bro...ur videos are amazing bro ...and ur way of teaching is awesome bro ... and we are learning so much information from u bro ..thanks a lot bro ...
Thanks for the great tutorial!
Can you tell me pls, what redactor do you use for the demonstration?

Thx for sharing...!!!! Greetings from germany Christoph 👍👍👍👍👍
Thank you 👍 for this helpful video .
Thanks a lot, Keep it UP!!!
great job buddy
I'm really enjoying your lessons. I'm fairly new to CS to you lost me at 13:00 but otherwise, great video. Maybe one day you can drive deeper into the math
I understood the linear probing and double hashing explanations but at 13:00 he started speaking gibberish.
Waiting for your next video on data structure.....only following you for data structure..
Love ❤️ from INDIA..🇮🇳🇮🇳🇮🇳🇮🇳
Good explanation man..
you're the goat thanks
Hello!
Thank you for explanation! But I think I misunderstand one point.
Can you check whether a mistake in double-hashing search and insertion complexity estimation?
If m1 and 1/(1-alpha)
Hello sir, i have a question. why in the hash table that used linked list, the new elements (that collides) we put it in the beginning of the linked list not in the end? thank you
love it wow almost 1000 views in 30 minutes and no dislikes amazing keep going!😘
Thank you!!
@@CSDojo no problem,love you from india

Thanks, helped a lot
Very nice, thank you.
A video on how to improve my computational thinking... :D
Is there any reason why CSDOJO appended 'd'? to the second hash function? Or was it just there to be different from the first hash with a different key.
Thank you for this video.
feeling a future with hashing after this video xD
Great video
Hi; thanks for the nice video. Two corrections: on 13:33 the reason is not to cover all the array. The reason is that it makes sure that no two elements will be positioned in one cell anymore. Also on 13:44 c should be a positive integer also it SHOULD not be divisible by m. For example m = 7 and hence c cannot be 14 although it is positive (since 14 = 2*7).
Did he admit it's wrong?
It would be amazing if you can continue doing this amazing course!
and like in the beginning using Java.
(Java because you are focusing on to teaching the logic and understand the concept and Java seems like the perfect language unlike Python)
and even I can't know how much effort it takes, time it consumes... Overall how hard it is to make these videos in this quality... but I can say that you are doing an amazing job and people that has seen your videos can see and appreciate what you do.
I personally want to say thank you for making these quality introduction videos and looking forward to see more in the future.
Have an amazing day!
Keep on being clearful #data nd algorithms can be difficult💜
U mean cheerful?
Hi! Can you explain what graphs are? Thank you for your effort!
thank you for this great video. I have a question though: I did not get why search can be O(1).
Say you have a 1/3 filled array with 9 elements total.
Say you have a 1/3 filled array with 10^99 elements total.
Why wouldnt it take much longer to find an element in the second array?
