Sir!
Make a video on pumping lemma
Difference b/w example no. 1 and example no. 8??
i am so glad i understand hindi...
Excellent work..........In so simple language ...................which is easy to understand...............thank you................
Sir, you explain in hindi is so much Mindblowing
Its a wonderful ques for univ.and gate exam thx sir
thank you sir you are my inspiration...!!
You're most welcome dear 😍 Keep learning & supporting, do visit our website www.knowledgegate.in for more amazing courses & contents 👍😊
Self referential note:
If any language is finite,then it is a regular language
awesome teaching...
Thanks a lot sir. Very helpful video
Thanks sir ... Very well EXPLAINED 😃
please upload more videos on toc sir...
Good video air apne mera concept clear kar diya
Glad to know this, keep learning & stay connected for more amazing contents👍😊
sir please complete toc lectures as soon as possible
Thank you sir
U made it crystal clear ✌️
Thank you so much Shradha.. Keep learning and supporting !!
awesome way of teaching sir.........I salute you please upload all subjects video
Sir ,you are great. Huge Respect and Love.Keep Blessing sir...
Sir plz explain about pumping lemma

Thank you so much sir. It's help a lot in net exam.....
Thank you very much.
brilliant sir ...thank u
U r awesome...I also wish to become like u
in one and two...epsilon is to be present as 'n' can be zero
Very helpful video
Thankyou sir
Concept concept......kudos...
Thank u so much sir 🙏
sir , at 11:08 , In example 8
how can we compare the strings if the range is bounded ?
let say L = a^nb^n / 1
Fantastic
Dear sir thanks for the tutorial.
I have a small doubt. hope you ll not ignore.
If I am not wrong, we design machines (here FA) for language not for a specific string. In the question 5 for each value of n we need separate machines (I can't think of a single machine to work with values from n=1 to n=10).
Correct me if I am wrong.
Golak Bihari Dhal watch from ~7:25 min again....
this is the technique which we can use to design a single machine for 5th question which will satisfy every criteria.
question no 1 and question number 8 dono hi to fir regular hona chahiye naa kiyunki Q8 me bhi toh order maintained ho raha hai.....
but order k sath sath number of alphabet bhi equal hain aur vo FA machine count nhin kr skti.
Sir in first diagram of this lecture.You took b when changing state. This way b will become minimum string . We can't have epsilon this way.It is not correct I think.
The initial state was also final, so epsilon will be accepted :)
Sir plz discuss using pumping lemma. Thanks in anticipation
anticiation? LOL
confusion in first second third if they are regular then why eight bcoz limit to same hai na n>=0 or m,n>=0
Please join our official telegram discussion forum and put your query there. tiny.cc/telegram_kg
Thank you sir
Sr in question 1 and 2 your are fixing permanent b and c respectively,what if we have m,n both zero
Sir , I appreciate your effort .
But I think are is small mistake in Example 2 ) bcoz u can't generate string a^1 b^0 c^1 i.e. ( ac ) if m,n,q >= 0 using your DFA representation (is wrong) . According to your DFA representation condition should be m,n,q>=1 or (m,n,q>0 but not >= equal )... According to your DFA representation its not possible to generate string 'ac' .
Correct me if m wrong . :) THANKS
It can produce epsilon with b^0
Use NFA
Mr Rishabh I think if u put null on the place of b that is transection between q0 and q1 then your problem will solve
Mr Rishabh it's NFA Representation not DFA Representation
loved it !!
amazing
Is the designing of 2nd question's NFA true ???
I think designed NFA will fail in case of "aaaacc" like all strings, where n=0
Keya hoga aap batiye plz.mera vi confusion hai ...
Thanks for the video Sir. Can you please put a video explaining pumping lemma ?
Sir, its "whether", not "weather". Please change your video's thumbnail and title. By the way, Great Work.
Caroline Channing 😂😂
Awesome
Too gud sir thanks
thanks a lot priyanka...
Thanks
awesome sir awesome!!!!!!!!
Thanks sir ji😆😅😅😄😃😂😀😉😊😋😎😎
In question no. 2, let us suppose m=0, n=0, and q=1 then the output is only C how did it come by this design, I think we must put epsilon
Superb
sir first question me m and n ki value bhi to infinite h to vo bhi infinite automata hoga na?
Nice sir
Sir jab a ki power m and b ki power n thi vo b toh infinite thi na sir fir b vo regular language thi...But jab a ki power n and b ki power n thi tab kese Ni bani...Hum same logic use kar k iske liye b NFA design kar sakte h na..
I have also this same doubt ..plz clear this
a^m b^n : The number of a's and b's are independent of each other and need not be equal this means we can have ANY number of a's and b's so DFA can be constructed of accepting strings having any number of a's followed by any number of b's.
a^n b^n : The number and a's and b's here need to be equal that means we have to STORE the number of a's and then compare the number of b's with the number of a's but the problem is the FA does not have any such memory to store the number of a's and b's hence comparison cannot be done so dfa cannot be constructed for this language. Hence language is not Regular !
Hope that helps ! :)
Bhumika Gupta yes but that any could also be infinite... So what about that

What r various models to represent regular language
Thank u soooo much sir...this video helped me a lot.
Sir can we construct FDA for all INFINITE languages if they are regular?
Sir please Upload DAA subject video in hindi ......I hope you will be respond my request
Thank u sir, i was too much board to study this subject but after seeing your video tutorial i an excited and i interested to study this subject...... Again Thank you sir..
hi sir i have an query n>=0 is mention question 1 and question 8 also same so how both languages are different on the basis of language
Sir first question aur last question mein kya difference hai
Thank You Sir🙏🙏🙏🙏🙏
You're welcome Subhadeep, keep learning & supporting. You can also visit our website www.knowledgegate.in for more amazing videos👍
awesome
Sir in this video take question no 1 usme vhi toh m and n vhi toh greaeter than equal to 0 hai phir yeh sawal kuy regular hua......but question no 8 is not regular why...sir???plz give the answer plz
👍
sir if we use pumping lemma then grammer 5,6,7, come out to be not regular..i m a little bit confused
Pumping lemma is not guarantee of non regular language , pumping lemma is guarented for regular language always
My que is if we can't say on comparing at infinite number say '' n`'' then how can we say at a^m and a^n, since m and n could have infinite values also
In case of a^m.b^n altough m,n may tend to infinity but Finite Automata can be drawn because no memory element will be required, a memory element will be required in case of a^n.b^n because no of a must be equal to no of b since Finite Automata doesn't contain a memory element therefore in this case Finite Automata can't be drawn.
Thank You Sir
Most welcome dear! Keep learning & stay connected! You can also check out our website www.knowledgegate.in for more amazing videos & contents👍😊
Question 1) mey bhi infinite ha aur Question 8 mey bhi. toh aik accepted aur dosra rejected kiyu ha?
Kyoki 8th me a &b equal hone chaiye to uss ko yaad rakhna padega,memory use hoga par 1st me aise kuch nahi hai iss liye 1st ka FA ban jayega aur 8th ka nahi banega
language is infinite...in case of example i).ii) and iii). Still they are regular why?
If example 1 is regular why not ex 8 becoz example 8 also has the order but dont have the finite so it is non rglr but look at ex 1 there also order is same and order is not countable and it is regular how it is possible
Sir confused in que 1 and 8
1st and last question quit similar because both language goes to infinity but ans is different,How?????
Cool
plese upload more video on toc plese sir
first and second question me v toh range bounded ni hai where m>=0 and n>=0..........
can anyone tell me that how |w| = 4 ?
Sir a^n b^n ngreater than equal one
Sir , In example 1 and 8 range is infinite then how can 1 is regular and 8 is not?
Q2
@@sanbha1565 I didn't get it
@@prachipolakhare6440 as q no.2 also same as 1and 8.
ohh yes but how Q1 and Q2 are RL and Q8 not?
@@prachipolakhare6440 all q are RL
L= {a^m b^n} m,n>=0 es mai m or n ka value kaise lenge m phle lenge 0 fr n lenge
👏
Sir plz make videos in english for all these toc topics..
1 and 2 will be Not Regular Languages
