This is wrong ..we use new production S' or S1 when on right hand side there is S but in this ques there is no S in right hand side but still u create new production.
tmrw is my exam .. learnt the concept in just under 10 mins .. while lecturers in my college took whole lot periods to explain them thanx for the help mam 🙏

Good day, Priya, thank you very much for taking out time to put these videos out, your series has helped me immensely. however, in an earlier video where you introduced CNF, you explained away a unit production without eliminating it, while in this video, you've shed more light. I do not know how the contradiction can be reconciled, I just thought to point it out. thank you very much once again.

If there is s on right hand side.. We have to take s'->s.this is the rule. here there is no need to take s'->s, because there is no s on rhs. May be she is wrong
but after replacing production of B with B then it will not rechable from S symbol then how it is ..,i'am confused can any one please having the soluton why B production is writeen as it is......😅
I had a doubt that why we didnt do removal of useless production. If we does that directly it iwll go to s1-->a,b which is in CNF. We can actually remove useless symbols from there @Education 4u

you didnt explain in line
S --> a | aA | B
why we didnt put null in capital A of that line ?
because it is already having a if we put means it will get like s->a/aA/B/a it is coming 2 times so it needs to put
I too have toc exam tomorrow 😂 thank you mam for your support we are learning in easy way 💐💐💐
Was this helpful
@@saminiyazgawandi3954 yesp this is help ful i have exam within 2 hrs i ll update you as well.
there is no need to define a new start symbol because in RHS there is no S.
isn't it? i had the exact doubt.
I thought the same thing
This is wrong ..we use new production S' or S1 when on right hand side there is S but in this ques there is no S in right hand side but still u create new production.
She does not know that
Yup
in neso academy . learnt that new start symbol is to be made if S occurs on some right side. but u said sth different.getting confused
right
Yes dont refer to this

No 1 ever cares to read your big paragraph Be short and crisp and point to point
yes, but answer is right .... she just copy the javapoint website notes

Shouldn't A be removed since it is non generating symbol?
U r confused .. U have made simple thing complex to understand . SAD :/
Ma'am, isn't S is usless symbol ??
very clear concept you teach thank you so much
if two terminals comes, that will effect or not mam??
its effect brother ,i think
in 2x speed production sound like protection , i am literally confused at some point
So ambiguous method.
Thank you 🙂
that thanku is so cute maam
why is S1-> S added i dont think it is necessary because the starting non terminal was not repeated anywhere
VEry good explanation, thank you mam
Thank you so much
Thank you so much for teaching 🥰 vry easy to undrstd all topic
Thanku mam.. concept is much more clear in ur lecture comapare to colg lecture
Thanks
Except for the first step others are correct.
Nice explanation.
Thankyou
how ??
no S on RHS
Your r very confident to enough....
She is totally confused
varun vaiyaa>>>>>>>>>>>>>>>>>>>
Thank you
Nice teaching
In final result you not added So------> Epsilon
thanKS
What about the repetition in S and So. Aren't we going to remove that.?
Mam most of the time you look confused.
A big Thankss To you Mam
Why we can't replace BB with R ??
Good explanation mam 👍👍 that's correct one
....
Thanks madam
A->AA is also CNF????
very well explained and very simple to follow thank you very much
Mam please try to write letters short in size so that the entire problem can fit into 2 pages so that there would be no confusion
Abe yaar
exactly

mam you are ther one , make everything easy to understand

excellent video
THANK sO MUCH MAM
when x-.> a then the production we may get is s->X/XA/AX/b which may be not a cnf
X -> a does not mean that a -> X
super
Mam why u changed s1 to s0 mam
wf is it?? nothing I understood
First step is not needed.
U can avoid it
GREAT

The start variable is no where in the production rules, expect the first production rule. Then why should we replace the start variable?????
"From a source, I have seen that the start variable is replaced only when the start variable exist in other production rules."
Exactly
She copied it from javatpoint
thankyou madam
U r just confusing not expllaninh it properly ratta marna band karo bhai
wrong info yar since S doesnt exist at RHS we can't create new Start symbol
Good
Ur Step1 is wrong, no need to add new state "S not", else everything is right
What is correct
thnks mam❤️
Miss, why we took the new start symbol? is it mandatory? S1-> S
please let me know soon, Thank you
If there is s on right hand side.. We have to take s'->s.this is the rule. here there is no need to take s'->s, because there is no s on rhs. May be she is wrong
@@snehi_05 yes. It's wrong
She Is Doing It As Per Rule But I don't think that matters...
Apply it when there will be S In RHS..
Both Will Be The correct
B is not reachable from start so why you didn't remove it?
How A is reachable and from there we get B
I think S-> a| aA | B |S
Helpful
She is already confused..

whoever liked the Neso video on this topic better, give a like!
there's no need of s' i think
"So" production is not required here...
but after replacing production of B with B then it will not rechable from S symbol then how it is ..,i'am confused can any one please having the soluton why B production is writeen as it is......😅
Because from A you can reach to B
B is useless production since no link
Here A is a useless production .but it is not removed why??
mam hindi me pdhao na plz
I had a doubt that why we didnt do removal of useless production. If we does that directly it iwll go to s1-->a,b which is in CNF. We can actually remove useless symbols from there @Education 4u
same question dude
did you find the solution for it ?
@@simarsinghchugh8402 Yes bro, its been long back. We can do that too . Better follow remal of unit, epsilon and useless and then do further
simple problem ko itna complex kar diya ki pura mood kharab ho gaya
I want ur help Mam,can u help me?
Very confusing mam
One more example madam
Warning Students!!!
Please delete this vedio, because it is wrong we never use S' when S is not appear on the RHS
Baki right hai ya Nahi
couldn't understand what you teach mam...
confused,
First step is wrong
kuch samjh nhi aya
The correct ans is
S- a/XA/b
A- YB
B- AX/b/a
X- a
Y- XB
What happened to another Aa
Step -3 mein kuchh samjh hi nahi aaya😐
thankyou so much
thanks mam from ethiopia
It's so confusing here,
Are madam question to likha karo next page pe
Completely confusing mam
Step 2 is confusing can anyone explain
for that, you need to learn grammer reduction
Kuch samj nahi aya 🤧🤧🤧
Madam agar aata nahi ho to chod do but bacchon ko galat maat padhao .. the books have more simplified solved examples than her explanation.

So confusing and complicated vedio
Mam you are confused yourself
kch smjh ni aaya 3 bar video dekh chuka
Bhai kese pass krru ye beekar subject 😢😢😢
Madam start symbol me bhi A ke place pe null put karenge???????
this is wrong !!!
