Reaching this lecture in just 2 days from starting, your teaching style is osm bhaiya ❤️❤️❤️
Great Explanation Sir now I m confident for my examination
No words sir👏.... You are really really amazing person in Computer Science field.... There are also lots of channels available in yt but none one can explain like u 💫❣️..... Thanks for giving us so accurate information about each topic ✨✨....
Sir par kahan hai aapke..
Bas aishrwaad lena
Very helpful sir!
Referred dbms ,toc, CN and Found useful and understable..

You know what I can give lectures now after Watching ur TOC playlist
Today is my exam, and i see the video before 4 hours.
Thank you so much 🖤
Thankyou so much 🙌 it's really helpful for me
Sir! You are the Dawn of the Computer Science Thank you
Sir your classes very useful for me
Wow 🔥...

Thank you sir, ap ka lecture samaj agia.
Sir Mera aik Question hain, Sir ap nay (S------->AB) grammar li huwi hain
to sir ap nay (A) variable say aaA production nekali hain
to kia hum (A) variable aaaA, aA production nekal saktay hian.?
Tysm🥺
00:48 Understanding derivation and language production from grammar
01:36 Derivation can be done in two ways: leftmost derivation or rightmost derivation.
02:24 Leftmost and rightmost derivations focus on different variables
03:12 Produced A, AA, and lambda in left
04:00 B, B and lambda are the key variables in the traversal
04:48 Derivation tree helps in deriving strings from a grammar
05:36 The process involves opening and substituting variables in the rightmost position.
06:22 Derivation tree helps determine if a string belongs to a language
Sir,Please make video on CFG to GNF and CFG to CNF conversion
Whaaa whaaaaaaaaaa ❤️❤️
You are my floki😭😍... thankyou!!
Ur welcome
Bhai aap Computer Science ke Bhagwan Ho.
In rightmost derivation, the input is scanned and replaced with the production rule from right to left. So *in rightmost derivation, we read the input string from right to left.*
Love from gujrat sirji
Thnku sir
Sir , make a video ambiguous and unambiguous grammer please
Consider the following context-free grammar:
(a) A1 → A2 id(A4)
(b) A2 → id
(c) A2 → A2∗
(d) A4 → A3|epsilon
(e) A3 → A2 id, A3|A2 id
The terminals in this grammar are id, (, ), ∗, where $ is the end-of-input marker, and the non-terminals are A1, A2, A3, A4.
Input string id∗∗ id(id∗∗∗∗ id) belongs to the language generated by the above grammar.
Question: How can we check if the above grammar is left or right associative ?
Thanks in advance
Sir plz suggest me important topics in system software and software engineering for ugc net 2020 exam...plz sir waiting for ur reply
pls try to complete the series!!
sir A-> aaA,lemda kab tk krna hai A->lemda leke apne 3rd level pe hi terminate kyu kia?
I understand only yours video 😊
Sir please do videos on Artificial intelligence
tnx
why parse tree string read left to right?
sir i have a doubt in right most derivation, why did you take lamda on right side because we have to derive right most string na.
Thanks🧡

@@abdurrehmankhan4349 kyu love jihad kroge
so shouldn't we stop when we lamda if not then what's the point of LMD RMD
sir aap online aye the baad continue kyu nhi kiya?
Hello sir, Should both trees always be identical?
How to deal with these type of question when the grammar is given.?
Give strings that cannot be generated from the context-free grammar.
Sir yeh LMD and RMD sirf non-terminal pe use karte hai na??
sir gate k liye aapka lectures kaafi h Kya Jo subjects aap upload Kar Rh ho???
Sir can i suggest something sir pls subject wise previous year questions from 2004-2020 ke question krwa dijye
saying competitive exam is permanent😂❤
Sir dono condition me tree same hi banegi left most derivation and right most derivation....
What's actual difference b/w LMD & RMD?
Sir plz is topic k baad computer graphics krvana plz
construct context free grammar to accept the language L equals to a^n + 2 b^m+ 1 |n = m will you explan this my exams aare coming
sir thore mushkil question bhi solve krna sikhaye paper me jb krne beth jate ha tu kuch nae ata jitna easy ap btate ha utna halwa nae ata paper me
Anyone from CU?
Yes bro
Yes bro😂
Yes
stop kb krna h lambda laga k end m ya kasa pta chalgya
Show that the following grammar is ambiguous
S-> iCtS
S-> iCtSes
S-> a
C-> b
Uttrakhand technical University
but your answer pf left most derivation tree and right hand derivation tree are same no difference between them

haiy shukar haiy ap Urdu ma lecture daity haiyn
Sir Jo Capital A and B hai woh kha gye
Sir aap saare video me yahi bolte hai ki ye competitive exam or college yaa university exam me babut puche jaate hai. Kabhi to bol diya karo ki ye naa to competitive exam me or naa hi college or university exam me nhi aayega 😁😁😁
#DoNotStudy 😁😁
Sir apna num mil sakta hen?
aaA->aaaaA this step is missing here.
Bhaii tere kitne aaye the toc mein mujhe nahi lagta tune first try mein clear kiya hoga 4 baar to backlog aaayi hogi tujhe TOC mein khud padh le phir mujhe pada nahi to teri vajah se meri college mein pehli back aayegi aise lag raha hai mujhe.....'
Tameez se baat kar
Tujhe or kya ayga backlog chorkar , parhna to ata nahi hoga
