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

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

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

Sir how take a input string to language
Thanks for explaining
You're welcome divyasri. Plz subscribe to the channel and if possible share with your friends. Thanks in advance.
Sir is this compiler design subject or. Flat??!
cd but in flat also we have this concept.
We can derive aabb from right too
Okay. Plz subscribe to the channel and if possible share with your friends. Thanks in advance..

@@SudhakarAtchala sir can you please share me the links of finite automata videos..
In Playlist there is only 15 videos...I can't find remaining videos of finite automata
uploaded 15 videos only. very soon i will start uploading remaining videos
Sir for consructing parse we should to take only left most derivation or right most but you take both it is possible sir
As per my knowledge we can take one lmd and one rmd also. Plz subscribe to the channel and if possible share with your friends. Thanks in advance..
Why are the strings derived step by step ? Can't it be done in one step itself ?
no ,in a particular step we can replace only 1 symbol. we have to follow step by step procedure only.
sir i have a dought sir in first example why we cant use (E) sir
You can
sir what is difference between ambiguous and LMD &RMF
We are checking whether grammar is ambiguous or not using lmd or rmd .

@@SudhakarAtchala 24-04-2019
But sir here both the parse trees are same, how can be the grammar said to be ambiguous
But derivations are different one is lmd and other one rmd. Plz subscribe to the channel and if possible share with your friends. Thank you so much.
