formal languages and automata Construct an NPDA for accepting the language L = {ww^R: we {a,...
Construct a NPDA with transition graph using 4 states that accepts the language L={w: na(w)-nb(w)=2} on Σ={a,b} subject-- formal language of automata theory.

Question: For = {a,b} construct
the DFA that accepts the language consisting of all strings over
the with no more than
one a.
The DFA constructed should be in a form similar to the below but
obviously built using the above language:
We were unable to transcribe this imageWe were unable to transcribe this imageb b b 1,1 2,3 3,2 a a
b b b 1,1 2,3 3,2 a a

Study Question.
Find the equivalent DFA from the following NFA which is represented by a transition diagram. The black state represents the final (accepting) state.
AUTOMATA Given the language L, L = {w | w ∈ {a, b}* and w starts and ends with the same symbol} (a) Define the context free grammar G that generates the formal language L. (b) Define the deterministic pushdown automaton A that recognize the formal language L.
