Derivation Tree (Left & Right Derivation Trees)

[@frontback4574]

In my 4 th semester I studied automata from nesco because my teacher sucks and I got 68 out of 100 in my automata and I'm happy that I have survived that course all credits goes to you Sir .

[@mohammad-karbalaee]

Sounds about right about me too.

[@nicolasningshen23]

our teacher sucks too LOL.

[@UNMEASURED100]

Our teacher is good but I cannot focus in class sometimes..

[@shadowslayer2248]

Same situation here. Really lucky to have Neso as an Angel that will help us ace our exams.

[@krishnakarthik4752]

Computer science courses, like the ones on automata theory and theoretical comp sci, are often quite hard.

[@dogemaester]

At least I get some aSS from Neso. Thank you Neso.

One day I'll be mature enough to read the production to aSS without laughing.

While constructing the right derivation tree, the string has to be read from right to left is it??

Let's say we have aaB .(B-->b).In this case ıs aab left most derivation for us ? And similar to that we have also right most derivation as aab . that means the left and right most derivations are the same ,right ? Please answer

derivation tree or parse tree are same??? or different ???

[@harshiscool007]

same

[@nancyanto4988]

same and different name of the parse tree

[@norhaking]

if its for CFG ..then why to use that T..there will be sigma right ?..or Derivation tree is also applicable for normal
regular grammer too ?

[@subhajitdas8075]

sir please say that is there any difference between parse tree and derivation tree??or both are same..??

if its a CFG then sigma symbol should've been used instead of T no?

in the first example you write p as the starting symbol in the touple and then uses s as the starting symbol.......?

Yeah, derive as much as needed to obtain the string.
