32:15 Why is first of S d,g and not d,g,h because if we put epsilon in place Of B in A->BC, then we should consider C productions for calculation of first
Hi sir I am a big fan of your teaching style Lirerally I am waiting for your wishes for my exams and Really you are the one and only best lecturer in my point of view it means a lot to me sir❤
I hope I will do better in the semester exam.I have sem exam this Friday .I had failed in internals but hope I will do better in semester exam.Thank you sir
i wrote the semester exam well, by watching your lectures thank you sir❤,for bottom up parsers, we can draw flow graph little easier,hope you will add that in your next videos❤
I SALUTE YOUR TEACHING SKILL SIR . U R ONE OF THE WELL KNOWLEDGABLE PROFESSOR IN THIS UTBE . I ALWYS SUPPORT YOU KEEP IT UP. SIR YOUR WAY OF TEACHING IS REALLY UNDERSTANDABLE .

I thought I will fail Later My lecturer Shared your video links ❤️❤️Suman Sir
ya what you said is correct . We need to calculate first(C) also. But there is no change is no change in result why because we calculated first(C) for the production first(CbB). Thanks for your observation.

Hy sir I passed compiler design subject because of your vedios thank you so much sir yesterday we got jntuk results sir
Congrats
Very clear explanation sir.👍
Thanks sir.

32:15 Why is first of S d,g and not d,g,h because if we put epsilon in place Of B in A->BC, then we should consider C productions for calculation of first
Then it becomes first of A=h,epsilon
was stryggling to unerstand this, thank you sir
Welcome. Plz subscribe to the channel and if possible share with your friends. Thanks in advance.
Example 4: S--->ACB/CbB/Ba
A--->da/BC
B--->g/€
C--->h/€
So first should be {a,b,d,g,h,€} but you wrote only {a,b,d,g,h} but € not written
Okay. Plz subscribe to the channel and if possible share with your friends. Thanks in advance..

At ex 4 32:11 wen we substitute B as epsilon than it will bcome A-->C from A-->BC , so again shouldnt we calculate first of C And include..?
ya what you said is correct . We need to calculate first(C) also. But there is no change is no change in result why because we calculated first(C) for the production first(CbB). Thanks for your observation.
