Compiler Design: Finding First & Follow Sets

[@JordanAyala]

The only lecturer with an understandable accent

[@officialfrancismendoza]

This video is severely underrated. You explained everything so clearly and I understood it right away, compared to 2+ hours cycling through lecture slides and other youtube videos. Thank you!!

[@sameerkazmi7052]

This is a good video to learn compiler a day before exams thanks

[@andresdavila1316]

i am in this exact situation lol

[@prammar1951]

Wow finally someone explained it clearly, most other tutorials just complicate things. Thank you

[@AldoniSinaga]

3:11 " OK, so for computing *follow* these are the rules that you would have to *follow* " **giggles** nice dad jokes m8

[@pratimmoulik7349]

I'm studying for my compilers exam on Thursday. This is much easier to understand than my lecture notes.

[@MrSaintRai]

You are the first person that I can understand explaining this, thank you so much

[@inquisitive.mind25]

ahh perfect tutorial before compiler exam ....... thanks a lot ....

[@Sora-sz1nk]

OMG I was thinking I would never understand this, but you manage to make it so simple, thank you so much :)

[@liangjack3305]

I"m a cs student from China, appreciate your great video !

[@johnp4301]

awesome video the only video that speaks proper english and can understand

[@farhanchohan2479]

Superb explanation ! well spoken english with proper terms. If i were awake in the starting of semester i would be rocking but no problem i still will rock the ending.

[@SumbaSlice]

Finally someone I can understand. Thanks

[@asadhaider]

Thanks allot, I've watched so many videos to understand First and Follow but no luck, but your video helps me understand the concept more clearly. Thanks, Keep it up

[@myyt4e]

thank you SO SO SO SO SO SO SO SOOOOOOOOO much!!!! My exam is tomorroooooooow and you saved me

[@ash432]

Was struggling with follow set, now it is clear to me.

[@anusuyanallathambi248]

What is the intuition behind rule 3 for the follow set computation?

[@arpanmukherjee4625]

Why in the last example FOLLOW(T) [from the E -> &TE | epsilon] became FIRST(E) although E (which is beta here goes to epsilon)?

[@gbraghim]

Wow!! Good work! I've watched many videos and your video is the best one! Thank you so much for your work, I finally got the knowledge!!! Thanksssss keep helping us!

[@thilinachathuranga566]

The way you present is very understandable. Thanks a lot.. :)

[@DootLordtheDooty]

Cheers for this! Extremely nicely explained process.

[@stoup8778]

This was so freaking helpful. Thank u maam

[@codr6934]

Best Video for First & Follow sets (imo)

[@Nepal071]

Thank you for making this video!

[@AbsoluteZerosAndOnes]

Hey. in the second example S-> (A) | ε, why didn't we cancel out the closing bracket since there is the ε so that we use the of ⍺A method? Help clarify.

[@pizzavibes]

Great videos. Particularly helpful videos on First & Follow Sets, and LL(1) parsing table, THANKS

[@신호중-i8h]

Thx you saved my life 😂

[@danielrosales4596]

thanks for sharing this information!

[@sinamhm6405]

thanks, I've got exam tomorrow. it really helped.

[@Aksuduvhjrjiwoqo]

Very clear and exceptionally helpful

[@teezy13500]

Lol off topic...Just a compliment, you are probably one the most attractive computer science girl person I have seen.

[@milomolo7702]

lol, she is not that cute

[@developer_hatch]

Funny accent

[@sentinem]

Great! Thank you very much and keep up the good work!

[@pmcca]

What about a production rule A -> BqC where A,B,C are non-terminals and q is a terminal?

[@fatemaaurin746]

Thanks for this, Mif!

[@mahmud4191]

Thanks for the tutorial. I have a question: if the production is of the type A -> D* which form of production would it fall into, (2) or (3). Can it be said that Follow(D) = Follow(A)

[@squillace91]

good question! did u find the answer?

[@ChewyGummy17]

Right of A is not empty so First of * which is *.

[@khamanfarhat3129]

Derive D, eg. D= print B. so you print B * , Follow(B)=First(*) = {*}

[@riwajchalise8317]

How to calculate follow for patten like Aa?

[@chethanprabhu4475]

how is that first of opening bracket is opening bracket?

[@joodjindy318]

clear as a crystal! thank you man

[@minejohn1]

Thank you y're a life savior

[@manosvafeiadis5385]

Amazing explanation!!! Many thanks :)

[@inquisitive.mind25]

can you make a tutorial on how to generate parsing table with stack simulation ...

[@ninistories]

finally a video that makes sense

[@yousifal-patti7277]

Compilers exam next week :( Many thanks :)

[@Empriction]

It's understandable, but hard to apply to your own code :(

[@dafemartdafemart4020]

what if you have something like this for the first sets,, A -> Ax

[@amirhosein_gpr162]

Thank you very much!

[@info-cj7tp]

thnx it was really helpful u"r a life saver

[@edoardottt]

Nice Video! Thanks

[@shramanaroy7179]

Very nice explanation....Tysm

[@saaraa8605]

very good description.. (y) easy to understand..

[@akibnizamify]

Love from Bangladesh!

[@estiamaliqari5393]

Thank you! So helpful and understandable

[@karolbielen2090]

basically good video, but I think you failed to mention that you have to apply all applicable Follow rules, not just one. Alse you didn't mention that alpha might be epsilon (at least that's what I conclude from my notes made at classes)

[@ZirJohn]

i still dont get the follow sets but thanks for the first sets

[@michaelvigato3228]

Thank you, this was extremely helpful

[@a.sarlove]

I've got a question on example 2 .. u can write the first one as S->(A due to the ε then the follow(A)=Follow(S) so I think you should include $ to all your Follows . Or I'm I wrong ? :\ plus your tutorial is very helpful thanks :D

[@carlosog5]

I had the same question, I think you are right!

[@Sebasuraa]

How can you replace ) with ε? S -> ( A ) | ε would derive (TE) (aE) (a) or (b) or (c) or recursively derive A, but it will never give you (A, so I think you're wrong.

[@squillace91]

I dont think so, because you dont have A -> (AS

[@codebrothers5544]

Thought the same at first, but all the comments here are right. Only if there were a production like "(AS", so we can replace the S with epsilon and afterwards we could use the 3 rule.

[@Fajeth88]

Thx a lot it was very well explained.

Thank you so much............angel........................

great explanation, thank you so much

[@annelin1416]

Thanks a lot!!!

[@thomaspgeorge4339]

Thank you for this. :)

[@ibingobingo]

Thanks, but your're mixing different written form of the rules misleadingly: Rule 2 could be either "add FOLLOW(a) = FIRST(beta)" or "FOLLOW(a) is superset of FIRST(beta)" but not the form you're writing; Rule 3 is fine.

[@Flying1Machine]

how did you learn all this are my teachers bad or am i stupid?

[@aryamukherjee2443]

this video helped me ...Thanks Mifta :-* :-P

[@ecemilgun9867]

Thank you a million :)

Thanks , i'm very grateful ^^

Tq for the great i was blank when my teacher taught me this

[@bstrong17861]

happens to alot of us

[@chalietarekegn8491]

thanks for your video but not clearly readable like example T AND T' ,F AND F'

[@philliey]

What does =>* mean?

[@satya-official]

Applying productions multiple times. It is like Kleene star.

[@matheuscaldas]

Thanks a lot man!

[@NabidAlam360]

It doesn't mean J??? :v Chatgiya talent!
