02:05 Ambiguous grammar generates more than one parse tree for an input string. 04:10 Ambiguous grammar generates multiple parse trees. 06:15 Ambiguity in grammar can result in multiple parse trees for the same input string. 08:20 Explaining ambiguous grammar ambiguity 10:25 Demonstration of ambiguous grammar 12:30 Leftmost derivation expands leftmost non-terminal 16:36 Ambiguous grammar generates multiple parse trees for input string.

[@adelnourbakhsh]

great teaching but there is an issues in example 1.two parse trees are the same . we should find two different parse trees to say that our grammar is ambiguous.

[@SudhakarAtchala]

one is left most and another one is right most. Please like the videos, subscribe to the channel, and share it with your friends. Thanks in advance.

[@manish4275]

some textbooks say grammar is ambiguous if more than 1 left parse tree or more than 1 right parse tree can be constructed.

[@SudhakarAtchala]

A grammar is said to be ambiguous if there exists more than 1 parse tree(2 left parse trees or 2 right parse trees or combination of both) for an input string.

[@AdityaMuley-ws1cl]

Pu t another way, an ambiguous grammar is one tha t produces more than one leftmost derivation or more than one rightmost derivation for the same sentence. I guess , sir we should get more than one lmd or rmd

[@SudhakarAtchala]

Both are correct only as per my knowledge. Plz subscribe to the channel and if possible share with your friends. Thanks in advance..

Sir edhi ambiguity kada ah ?

[@c.d.premkumar6867]

Why are the strings derived step by step ? Can't it be done in one step itself ?

[@SudhakarAtchala]

no ,in a particular step we can replace only 1 symbol. we have to follow step by step procedure only.

Removal of ambiguous grammar videos can you upload sir

[@SudhakarAtchala]

we can remove ambiguity using 2 approaches such as left recursion and left factoring.
