Lec-15: Difference between LALR & CLR parsing table | Imp. Example | Compiler Design

[@_AroobaSajjan]

That happiness when u search a topic and find Gate Smashers video already present 🤩🙏👏

[@kanakyadav2498]

So, finally i got a one stop solution of my compiler design examination. Firstly, due to this pandemic, neither we could avail the books nor there were proper video lectures available on youtube to help me out in this subject. One of my friend suggested me this channel and surprisingly, watching the first video of this video series, made me realize that its going to be enough for my complete subject. The way this teacher has explained the concepts, his clear understanding as well as the clear vocalization of the subject had a huge impact. No doubt, this is the best of the series, i have ever watched in terms of Engineering subjects. No words to express my gratitude. Students like me who love to reach in depth of a subject, you have given a one stop solution. I cannot stop ravishing and thanking you "SIR"🤩. God bless😇

Bhaiya Jii thank u apne 3 video k baad aakhir bata hi di LALR ki parsing table aur merge karna bata hi diya THANK YOU SO MUCH❤️❤️❤️❤️❤️❤️❤️❤️

Hello,sir! Your are teaching very very well, keep it up,lot of love from Pakistan. But sir, at the cononical item 4 you do wrong, you was to go for (NT) S but you went for terminal ( .Because of this mistake,tables of CLR and LALR 80% changed. Thanks for Every Video. 😇

Finally cleared all steps 👍👍👍👍👍👍👍👍👍 Only because of you sir Hats off to u 🙏🙏🙏🙏👍👍👍👍🙏👍🙏👍🙏👍🙏👍🙏👍👍🙏👍

Such an exceptional explanation, just wanna correct one thing that ordering has a mistake I mean I4 should be I5 and I5 should be I4 , which makes a difference in the Parse table anyway love the way you teach sir ❤❤

yes sir your all videos is helpful.

Very important question discussed

[@gulamali6080]

Concept clear sir😊😊

[@lalitkumar8445]

Hi sir, in LALR table u merged S7 and S9 as S79 for state no. 58.....but if there is any merger of reduced for any state then how to write e.g merger of r1and r2 for any state then we write it as r12 or r1r2 ?

[@animationcrust1993]

Very easy explanation... thank you 😊

[@sohamsamanta]

[@jyothisai1]

sir will you add liveness analysis??

[@zafeerkhan7617]

thank you sir...

[@atharvshah5582]

Will LALR and CLR parsing table will be the same if there are no common items? i.e if there's a case where they cannot merge.

[@adityasharma1351]

Sir last vedio me bhi to look ahead same nhi the to apne bola tha ki vo merge nhi ho skti .fr yaha bhi look ahead different h to merge kyu ki

[@deepanshuujjainia9805]

Sir in question no.1 in CLR table row no. 2 shouldn't it be R6 instead of S6? (As it is reduced form)

[@khushiagarwal9553]

LALR wale table ke 0 state ke 1st column mein S24 hoga na kyuki 2 aur 4 ko merge kar diye hai

[@bhanvimenghani2156]

sir pls complete the video tutorials we are dependent on your videos only

[@diwakarkirar5102]

sir I2 state ( pe I2 pe hi jana chahiye tha na?

[@SumitThakur-hv9ec]

Pira parser padh ke gaya ma'am ne LALR me epsilon daal diya.

[@KapilGaikwad-dg2ob]

Sir, I made the CLR parsing table for the following Grammar:- S --> aAd | bBd | aBe | bAe, A --> c, B --> c. It was like in [0,a - s2, 0,b - s3, 0,S - 1, then 1,$ - Accept, then 2,A - s4, 2,B - s5, 2,C - s6, then 3,A - s8, 3,B - s7, then 4,d - s10, then 5,e - s11, then 6,d - r5, 6,e - r6, then 7,d - s12, then 8,e - s13, then 9,d - r6, 9,e - r5, then 10,$ - r1, then 11,$ - r3, then 12,$ - r2, then 13,$ - r4.] Is this correct? (The sequence I took for the terminals was a, A, b, B, d, e, c, $, S) (In Item no 6, C was reduced, so I added it in the go to which is d for A (A --> c., d) which is production no 5, and e for B (B --> c., e) which is production no 6, hence r5, and r6.) (In the same way I did it for Item no 9, where A --> c., e and B --> c., d, hence it was r6, r5, placed in d, e.) Then for Items 10, 11, 12, and 13, I put the reduced values in $ since it was the go-to of those, which became r1, r3, r2, and r4.) Is my table correct sir? Please guide me. I know it's hard to explain this in a comment, but still, I am trying. 😅

10:26 it will be r2 in (2,)) and no s6 in (2,a) in CLR parssing table

[@sushilghimire2899]

while merging 5 and 8 , there is s7 at 5 position and s9 at 8 position ,merging is possible? Let me clarify this!!

[@ashishkumaryadav5252]

Same doubt

[@pradipmalla8059]

please complete cdc lectures sir

[@karthikbhandary879]

what if there are odd no of states then should we just leave one of the states as single?

[@vinitakeer515]

Thanks sir

[@NandhiniRCS]

Bhai I want video on triggers and active databases plz as early as u can please bhai

[@shashankkothari8066]

Can someone tell me if the order of counting the items matters or not. Because the table also depends on the order in which we count the items.

[@shashankkothari8066]

I think it doesn't really matter how you order the items and how the table looks because the main purpose of this is just to check if the parser will accept the grammar or not.

[@madhavsingh8384]

Sir kya ye jaruri h ki LALR table banane ke liye CLR table banana jaruri h

[@akahito8053]

For the LALR parsing table there is no state as 2, 3, 4, 6 so what does the S2, S3, S4, S6 represent as written in the rows 0 and 24?

[@pradipmalla8059]

exactly

[@chagantisubhash]

S2 will go state 24, S3 will go to state 36, S4 to 24 and S6 to 36. Just like how we merge Finite Automaton in DFA.

[@crispytek6783]

Is there no such thing as a shift-shift conflict? S79 seems like a conflict but you claimed it isn't. Please help!

[@20_ayushsahu32]

Which is more powerful lalr or clr ?

Clr

[@rishabnegi2334]

Sir you have said in previous lecture (L-14) that there will be multiple entries but now you are merging, so it's confusing me. Sir please help

Is there any rule to give names of states

अगर CLR मे sr conflict नही है तो LALR मे भी नही आयेगा लेकिन CLR मे rr conflict नही आ रहा है LALR मे आ सकता है

In the lecture 14 video you are claiming that we cannot merge two productions with different lookahead but in this video you're contradicting your own self. Please clarify this doubt of mine, I have got an exam tomorrow. Thankyou. kzbin.info/www/bejne/fYDPpIylm6-dr7M
