Hashing and Hash table in data structure and algorithm

[@Shaltha]

Came looking for an explanation of double hashing, ended up watching the entire playlist. I understand this chapter in my data structures class so much better now, thank you!

[@sonisingh6781]

Saurabh's pick line.......... He is B.Tech from IIT and MS from USA :)

[@soulsaga]

Hey man! Salutations from Australia! Thanks for explaining this out for me. It really helped me grasp why hash tables are so useful.

[@priya24gill]

you made a mistake... in very first step, when you took mod of 21 with 10 i.e 21mod 10=1 but you save 1 in 1 storage table, you have to save 21 at 1....

[@wilmar8192]

by "not visible" he meant the color he was typing with..

[@dhimanroy2831]

Avneet Benipal yes actually

[@hamnarafique2849]

yeah..you are right

SUMMARY OF KEY POINTS: So basically a hash table is a thing involving hashing which is useful for hash tables. There're many distinct numbers congruent to one-another modulo a fixed integer. Hashing is fast because Hash tables and hash functions. Okay. Oh and multiples of 5, okay. Please let me know if I missed anything.

[@qee540]

I think you made a mistake in the 2 row '1' where the value of " X " is 21. there are all of us relying on you. thx

lul

[@sonaligupta8838]

Lolllll

[@Kemolz1]

great vid, its my first day im just curious to know why you would present h(x)=x%10 and not something thats more general equation of h(x)=x%size or something because i missed it and then came back to let you know how easy that small amount of important information was a little obscured for me. other wise great video

[@assaulterevil2493]

It made me easy to understand hashing

[@srirambalachander4286]

Thanks for the video..waiting for the next lecture...post it soon :-)

[@saurabhschool]

Yes, I have posted all videos on hash table

[@jacknoble1184]

why can't anyone make an instructional video about hashing without it being completely fucking mind numbing?

[@themikster1212]

ok

[@SpMeKP]

How about some code as well?

[@TheLiakos7]

Can u send me the code of this algorithm? In Dev C++? in C language

[@lakhanbenwal9729]

You have saved my midsem . Thanks a lot :)

[@PouyanArephpoor]

I just want to tell you I didnt watch your video because there was a long advertising at beginning :( I Very disturbing one

[@DoItNowNotThen]

thank u you explained very nice

[@nilashishchakraborty3983]

Thanks a ton for the lesson, Saurabh. I have a basic doubt regarding the advantages of Hash Tables. As we know, that implementing hash tables costs us the overhead of hash function. However, if we use an array of structures to save our dictionary pair we will not have to waste CPU cycles for calculating the hash function. In an array of structures, the key(in the dictionary pair) shall serve as the index while performing a search. For e.g., I have to store the following data set: (1, ABC) (2, CDE) (3, EFG) (4, GHI) and if my structure is called "info" then we can perform a search in O(1) time using "info[1].data" to retrieve "ABC". We will also have the advantage of never having a collision(if keys are primary :D). So my question is why do we use Hash Tables at all? Thank You. :)

[@joneshshrestha]

Hashing okay and okay Hash okay Table okay in okay data okay structure okay

[@vinodkp7905]

Very simple and helpful. thank you...

[@szanqoole]

wow what a teacher! amazing, I would love to be in a class that you teach, i never fully understood before today. thanks

[@toufiq-ul-alam6475]

i assume that it will be 21 in the index number 1?

[@angladephil]

This video is very (much) OK !

[@kamleshbachani8132]

Correct me if i am wrong but we cannot enter anything at the 0(zero) index!!!!!!

[@seventea7]

Kamlesh Bachani Yeah you can, 20 mod 10 is 0. Or (any multiple of 10) mod 10 = 0.

[@shohrabhossain2022]

awesome....:)

[@preethimukundkumaresh8928]

Thank you so much it was really helpful to study!!

[@curtisshaw7688]

Best video on hashing. Hands down. Thanks.

[@gabrielpereiramendes3463]

Thanks a lot!

[@VikashSharma-wv5vv]

Very well explained

[@sajinarayanan4941]

Nice video.

[@Mr1Samurai1]

Great stuff, very clear and concise.

[@joshsmit779]

Excellent explanation!

[@rekha8875]

thank you soooo much......😊

[@Msvip11]

thank you so much

[@taymurahmed7119]

Love the way you are explains everything !!! Appreciated :)

[@asifanwarsadi7676]

Hey, thumbs up! It helped me a lot. Thanks :)

[@amitkashyap2986]

Keep up the good work saurabh :-)

[@saurabhschool]

Thanks Amit!

[@PrettySparkle1]

Great!

[@anshulrally287]

Thanks for the lecture. BTW, which drawing program , pen tablet and screen recording software you use for recording your lectures ?

[@saurabhschool]

I use i ball pen tablet and camstudio for desk top recording

[@anshulrally287]

saurabhschool and the drawing program on which you wrote with pen tablet ?

[@muhammadmustafa2365]

Anshul Rally😍😄😍

[@jeathtunes769]

how can 48.7 devided by 10 is equals to 8?

[@Gurpreetsingh-xd2cn]

+Jeath Tunes Its modulo(%) man not a .7 .

[@spreen_co]

**mouse wiggles restlessly** 'oke?'

[@moizazeem7362]

ay belol

[@vishalarora919]

Well Done!!! From Canada

[@marcushandley3017]

Isn't this just a dictionary?

[@yoteango]

Yes. A hash table is basically a dictionary.

[@sachinjaiswal4632]

Writing is so poor

[@rahuljain4691]

I think S.Saurabh needs to do some extra homework before explaining the topics.

[@Merajmohdkhan]

very good explanation although its understandable but just make it perfect please correct 21 value.

[@scotthawkins8707]

I didn't understand a single point that You tried to explain. Sorry.!
