The way this teacher articulated the ideas, along with his excellent comprehension of the material, had a significant impression.This is without a doubt the greatest in the series.I am speechless in my appreciation.

So, finally i got a one stop solution of my compiler design examination. Firstly, due to this pandemic, neither we could avail the books nor there were proper video lectures available on youtube to help me out in this subject. One of my friend suggested me this channel and surprisingly, watching the first video of this video series, made me realize that its going to be enough for my complete subject. The way this teacher has explained the concepts, his clear understanding as well as the clear vocalization of the subject had a huge impact. No doubt, this is the best of the series, i have ever watched in terms of Engineering subjects. No words to express my gratitude. Students like me who love to reach in depth of a subject, you have given a one stop solution. I cannot stop ravishing and thanking you "SIR"🤩. God bless😇
Thank you sir, the last point you said in the video was really useful as even I had that doubt from long time that why don't we call it RR conflict. Now its clear that it is due to the lookahead symbol 🙏
Go to the video link of LR0 or SLR1 the difference is only to write the reduce move in whole row in a parsing table in LR0 and write the reduce in only at the left of its follow for Slr 1.. And difference is only for the clr1 is to write the reduce move only at look ahead symbols.
sir i have a doubt that for item I6(A->c. ,d B->c. ,e), the reduced no. will be r5 and r6 so in table, we have to write r5 or r6, in look ahead d and e?
The reduce no. For d is r5 bcz of A's production no. Is 5 and for e is r6 bcz B's production no. Is 6 And for look ahead hm isme d or e me isliye likh rhe h qki jo . He vo e or d se phle h agr . e or d k bad hota to hm $ m r5 or r6 likhte I know ki apko ab iski jrurt nhi hogi but jese mene y doubt dekha vese kisi or ko iski jrurt pd skti h so isliye mene socha solution likh du syd shi ho
I0 contains the closure of augmented grammar...what that means is that it contains all the productions of start symbol with dot AND the expansion of those variables which has a dot to its left side. So when you put dot symbol to the start symbol productions, all those dots are either to the left of S' or a terminal. So we don't need to write the production of A and B. That's all
Sir, pehle canonical item mein apne A --> .c,$ and B --> .c,$ nahi likha hai...kya ye likhna zaruri nahi hai?? Agar aisa hai to total number of canonical items = 15 hona chahiye...??
Here, we are not considering A->c as A->.c and B->c as B->.c because First, In the production S'->.S, $ after (.), there is a variable / non-terminal 'S'. So, we just unwrapped all the productions of 'S' S->.aAd, $ S->.bBd, $ S->.aBe, $ S->.bAe, $ Now, in the above 4 productions, there are terminals after (.) in each production. There are no non-terminals or variables after (.) in every production. So, we are not considering the productions A->c and B->c in item. Hope you understood...
Question - how did you derived directly that there is no SR or RR conflict , is there any shortcut how did you know by just looking at Collection of item diagram ?
because the if you have to take a first and there is an identifier like +,d,a,*,etc. then you only consider the first identifier as the only first. Here d is an identifier therefore only d is taken as first.
Can you provide all the remaining lectures of this series of compiler ,I watched previous videos of this subject was too much impressive for me that's why I need full syllabus(gate,other Competitive exams). Thanks for your great effort
you should have explained its table also , i watched some other examples to understand this (we only put reduced state in {$,e,d} cause they were first )
can you also share or add parsing table, because at state I4 there are 2 reduce so in parsing table it will be "R5" in d and "R6" in e so in same row R5,R6 both will come ??? same doubt for state I4
here, we are not considering A->c as A->.c and B->c as B->.c because First, In the production S'->.S, $ after (.), there is a variable / non-terminal 'S'.

one of the best youtuber guide.... sir ur explaination is beyond infinity.... love u sir... thank u
I was badly waiting for next lecture sir. Thank you.

Very important topic in compiler design..
Hello , colleague 😅
Ur my snack
I was waiting for this... Thank you sir...
Sir pura btao na please parsing table kese banae
SLR wale vdos dekhle na.
Baki same bas reduced term look ahead pe rakhna. If you're still giving this exam 😅

trust me , our teachers teach us after learning from you
Your way of teaching is very good
Thank you sir for such beautiful content in free❤❤
Thank you sir for the Vdo..
Sir where can we get the CLR parsing table for this very example?
Yes
@@akashs8052 where , can u share the link
Go to the video link of LR0 or SLR1 the difference is only to write the reduce move in whole row in a parsing table in LR0 and write the reduce in only at the left of its follow for Slr 1.. And difference is only for the clr1 is to write the reduce move only at look ahead symbols.
Great sir gi
Best ever teacher ❤️❤️
Thank you sir. Great explanation ❤
Looking for a short trick to check if the grammar is in SLR, LR0 and CLR
keep looking cuz no algorithm because of undecidibility
Sir I have a doubt can you tell me that why is not add Production of A and B in I0 Canonical 🤔
there is no dot before a A or B from the S productions.
thanks alot sir for uploading
sir i have a doubt that for item I6(A->c. ,d B->c. ,e), the reduced no. will be r5 and r6 so in table, we have to write r5 or r6, in look ahead d and e?
Yes
The reduce no. For d is r5 bcz of A's production no. Is 5 and for e is r6 bcz B's production no. Is 6
And for look ahead hm isme d or e me isliye likh rhe h qki jo . He vo e or d se phle h agr . e or d k bad hota to hm $ m r5 or r6 likhte
I know ki apko ab iski jrurt nhi hogi but jese mene y doubt dekha vese kisi or ko iski jrurt pd skti h so isliye mene socha solution likh du syd shi ho
hi sir, in the First I0 shouldnt we also include the production rule for A -> c and B -> d ?????????
No, because there is .S and any production of S doesn't have A/B at start. So because .A or .B aren't present they won't be expanded.
Sir, In I-0 box ,why you not adding production rule of A and B
In I-0 , we write all production starting with . Symbol
Then why?????
Yes it right question and i have also doubt 🤔🤔🤔
I0 contains the closure of augmented grammar...what that means is that it contains all the productions of start symbol with dot AND the expansion of those variables which has a dot to its left side. So when you put dot symbol to the start symbol productions, all those dots are either to the left of S' or a terminal. So we don't need to write the production of A and B. That's all
@@atulkrishnan4673 Thank You
Sir, you are the best!
In I0 why didn't we add A and B productions ?
Whether in i0 state, we should add 5&6 production ???
Crystal clear🔮 . Thank u so much sir..!!!
Sir ye look ahead nikalte time ham ka next to left side ka first nikalte he kya?
plz make a video on parsing table of CLR
Thank you sir ❣️
CLR won't have SR/RR conflict ever? or it's just for this grammar?
Sir, pehle canonical item mein apne A --> .c,$ and B --> .c,$ nahi likha hai...kya ye likhna zaruri nahi hai??
Agar aisa hai to total number of canonical items = 15 hona chahiye...??
Ha bhai ese 13 canonical items bn rhi hai 🤔🤔
Here, we are not considering A->c as A->.c and B->c as B->.c because
First,
In the production S'->.S, $
after (.), there is a variable / non-terminal 'S'.
So, we just unwrapped all the productions of 'S'
S->.aAd, $
S->.bBd, $
S->.aBe, $
S->.bAe, $
Now, in the above 4 productions, there are terminals after (.) in each production.
There are no non-terminals or variables after (.) in every production.
So, we are not considering the productions A->c and B->c in item.
Hope you understood...
Difference between SLR and CLR is at 10:30
Waah
thank you ( i can't describe in a word but thank you!!)
Question - how did you derived directly that there is no SR or RR conflict , is there any shortcut how did you know by just looking at Collection of item diagram ?
Thanks a lot sir 🙏🙏🙏 thank u so much 🙏🙏🙏
Hi sir, @5:55 u took first () of d,$ as d only......why we not took as d,$ ?
because the if you have to take a first and there is an identifier like +,d,a,*,etc. then you only consider the first identifier as the only first. Here d is an identifier therefore only d is taken as first.
Sir , A -> c ka kya karna hai
❤❤❤
i am not indian but youre absolutlya blessing sir, stay blessed mann.
thank u sir❤❤
Thanku sir💫
Thank you sir gi.And you lives always Happy.You are a Great teacher and computer engineer.
Thank you so much
Thank you sir
If we don't have any terminal or variable after the A like s->a.A,$
How can we write in A->.c??
Plz tell CLR and CLR(1) are same or not
Can you provide all the remaining lectures of this series of compiler ,I watched previous videos of this subject was too much impressive for me that's why I need full syllabus(gate,other Competitive exams). Thanks for your great effort
perfect brother
if the grammar is
S->aAAb
A->c
the what will be the lookhead after opening S->a . AAb,$
will it be A or b??
8:37 sir we can direct the input on “c" to I6 in place of writing a new state (I9) right?
Anyone? Am i right?
Can you provide notes of all these lectures if possible? Thank you in advance
contact for free notes
Let say in A--> c if there was epsilon instead of c what should we do
In initial canonical item, why didn't he take production of A and B ?
you should have explained its table also , i watched some other examples to understand this
(we only put reduced state in {$,e,d} cause they were first )
What do you mean ???
Absolutely
I think for rows 2 and 3 there are 2 reduce symbols
d. e
2. r5. r6
3. r6. r5
Is this correct?
I still have doubt regarding how to make the Parsing table for this. can you please help?
Is the table available anywhere?
can you also share or add parsing table, because at state I4 there are 2 reduce so in parsing table it will be "R5" in d and "R6" in e so in same row R5,R6 both will come ??? same doubt for state I4
in above example there are two inadequate states
sir clr mein parsing table hai kya?
Sr operator precedence ka lecture ni mil ra
thankyou
Thank you Sir, Its very understandable
can somebody tell me
S -> Ba/bBc/dc/bda
B -> d
can we make a parsing table for this grammar??
Please someone reply !!!!
why is first taken here and not in lr(0) and slr(1)?
👍👍

after primary transformation check the same idea, you are getting .A and .B, that is where you will use that production
Sir plz make the video on LALR
Tnx alot sir.. all cleared my doubts you explain very well
sir can you share the clr table for confirmation?
Thank you so much sir... Please upload LALR soon as possible thanks
Sir can you please tell me to draw a parse table for CLR as well

Yeh clr1 hi h na?
Bhaiya Pura Course Upload krdo Exam hain
where is the parsing table?
But it is left factored grammer, don't we have to remove it?
LL(1) parser is sensitive to that, CLR is not. So we don't need to remove left factoring for CLR.
sir plxx come up with LALR fast
sir please make its parse table
sir table to banwayi hi nahi.. te most importatnt part... uske bina kaise kaam chalega
can you please add parsing table in this please

anyone have notes ?

Table values are written in FOLLOW in SLR whereas reduced Look ahead in CLR
So is this grammar CLR(1) or not? Anyone?
