Hi Gabbar... hope you are doing good. I had written to you about the changes you brought in my life, I hope you remember and now I am back again preparing for GATE 2015. In 2013 I had attended your SILK CN class but we couldn't complete as you hadn't come back, but this time I am sure these videos will suffice all the needs.. Thanks a lot. You are doing a real great job...

how do i deal with problems where arithmetic operators aren't there? How do you come up with a string that is used to design parse trees to check the grammar's ambiguity?

@sanomi4492 6 жыл бұрын

How about parenthesis?? If I want to add a parenthesis rule, which has the highest priority, without ambiguity into the very first example in this vid, should i write something like: A -> A + B | B B -> B * C | C C -> ( A ) | T T -> id Or, for the third rule, A -> A + B | A + (A) | B B -> B * T | T T -> id But I'm not sure whether this is UNAMBIGUOUS or not. Please someone help me out!

@kunalupadhyay7970 5 жыл бұрын

(examples of Boolean expression and after that )How can you say it is left associative, because when I draw it's parse tree I found it being right associative since right operations evaluate first

@damnikjain8985 5 жыл бұрын

Great

@DonatedMountain 7 жыл бұрын

For a boolean grammar would it no make more sense to have G -> not( E ) | t | f so you would be able to parse something like NOT( a OR b ) AND c??

How to remove the ambiguity if there is no operators like s tends to 0S1|SS|epsilon for a string 0011 like this problems

@saadmanahmed860 4 жыл бұрын

only for plus(+) associativity does not matter. but still (+) is left associative. + < * if we take care of two things viz. associativity & precedence . then grammar can be made unambiguous associativity - recursion precedence - level
