LALR Parser is a powerful lookahead LR parser that reduces the size of the CLR parsing table by combining similar states into one state. It works similarly to CLR but combines similar states into one. To construct the LALR parsing table, write augmented grammar, define two functions: goto and action.

better than gate smashers
gate smashers is also much better and I must say gate smashers voice is clearer than him.Appreciated. Their way of teaching is different but quite understandable.
Sb ka apna apna point of views hota hai
He teaches more deeply and precisely than gate smashers.
Bas har jaga competition create kiya kro khud se 😅
Real😊
Sir today is my first day on your channel and your videos are just 🔥... Thank you so much sir ❤.. for this amazing content 💗
Thanks and welcome
0:50 main topic starts here
6:27 skip to 7:50
example 1: states merged without conflict in LALR(1)
8:52 example 2: LR(1) = LALR(1)
14:09 example 3: conflict (16:19) upon merging in LALR(1)
exactly more confused now
U r my saviour in my uni CD exam
Thank you and keep up the good work.
Sir bht bht shukriya aapka mere doubts clear krne k liye 💓💓💓
Great teaching
Sir ye last wali lale ambiguity wali question meri finals k paper m aai thi... Bilkul dot aisahi banai

Nice

Mashaallah
Rules: LALR(1)
1. Minimise form of CLR(1)
Parser.
2. Combine only Those symbol whose LR (0) symbol will be same and look ahead symbol must be different.
3. If a cell contain more than one symbol in a particular cell it is not LALR(1) Parser Otherwise LALR(1) Parser.
A small correction 4b must be r4 not r3 (Edit: I was wrong as we write the no. of production rule after r)
Thanks a lot
DESH KA YOOVA!!!!!!
Bhai thoda side mai hatt jaya kro note bhi krna hota hai
Kal kis kis ka exam hai aur aaj vedio dekh raha hai
I don't understand why muslims feel ashamed to keep their original name as their channel name. I know this channel is for GATE preparation, but still you would have mentioned your name anywhere. Every other religions guys put their names proudly I have seen many muslim popular channels don't wanted to do, like CodeWithHarry He is Haris Ali Khan), Sir you are Shoaib Ahmed, so it's fine . I understand tho we live in Islamicphobic country but still please don't hide your identity.
I recognized you because you didn't keep your name.
rkha to tune bhi nhi hai apna naam
