You are so good at explaining! This and at least 10 other videos on your channel helped me greatly, thank you so much and please continue teaching.
Thanks very much!
I always had trouble understanding why cfl's are not closed under complement..it got cleared with this video. Thanks a lot
You're welcome!
Great video and great explanations! You're like meant to teach this stuff. Btw that plane transition screen had me dying 😂
Planes are not context-free
@@EasyTheory except United Airlines. They’ll punch you in the face and drag you out without much context
Thanks for the video! Great content helped me out.
You're very welcome!
This was just what i needed, thanks!!
you secured my successful exam
well, until shtf, we will keep pushing forward soldier ;-)
sir plz prove how inverse homomorphism of cfl is closed.
your proof for L* , is it a proof? I dont get it
hello, how do i test if CFL are closed to union and concatination?
Not sure what you mean, isn't that what is shown in the video?
@@EasyTheory yeah and you use | in union instead of U. Please correct me if I'm mistaken.
@@eclarexegulane U is used for unions of arbitrary sets. Languages are sets, so it works with them. Some people use | for unions of languages (e.g. in regular expressions), but using U is certainly valid.
Wow! This is pure gold 🪙
