5.18. For each of the following languages, give a transition table for a deterministic PDA that...
Define a deterministic PDA (give table of moves) that accepts the language of balanced strings of parentheses. For convenience, a special end-marker is added to the end of each string. Use the grammar S rightarrow T$ T rightarrow T[T] elmentof (b) Show the moves that parses the string []$, alongside with the corresponding steps in the left derivation of the string.
PDA:
please give me a PDA for the language.
You don't have to draw a diagram, but please illustrate the PDA
something like this:
1.δ(q0,0, Z0)={(q0,0Z0)}
2.δ(q0,1, Z0)={(q0,1Z0)}
......
12.δ(q1, e, Z0)={(q2, Z0)}
Thank you!

Use the pumping lemma for context-free languages to prove that
L3 is not a CFL.
L3 = { w: w e{a,b,c}* and na(w) < nh(w) < nc(w) }.
