Construct a Pushdown automaton that accepts the strings on alphabet {a,b,(, ) }, where parenthesis “(””)” matched in pairs. For example strings “((ab))”,”(a)b()” are in the language, while “((”,”(ab))” are not. Please determine if your PDA deterministic or nondeterministic. (With Proper Steps and explanation) PLEASE DO NOT COPY PASTE THE ANSWER FROM OTHER SOLUTIONS, AND PROVIDE PROPER EXPLANATION AND STEPS.
Give a PDA (Pushdown Automata) that recognizes the language L = {σ ∈ {x, y, z} ∗ | 2|σ|x = |σ|y ∨ 2|σ|y = |σ|z} You can choose whether your PDA accepts by empty stack or final state, but make sure you clearly note, which acceptance is assumed.
4. Construct a pushdown automaton for each of the following langauges – by giving its 6-tuple formal defintion and brief/precise interpretations of its states and transitions: (a) {a" x | n > 0, and x € {a,b}* and (x) <n}. (b) {W € {a,b}* | w has twice as many a's as b’s}. (c) (0+1)* — {ww | W € {0, 1}*}
Construct a deterministic finite-state automaton for the language L = {w ∈ {0, 1} | w starts with but does not end with 010}
Use a general algorithm to construct a (non-deterministic) pushdown automaton that corresponds to the following context-free grammar with the starting variable S: S → Aab, A → Sba; S → ε. Show, step by step, how the word baab will be accepted by this automaton. Its derivation in the given grammar is straightforward: S → Aab → Sbaab → baab.
Describe (or draw) a pushdown automaton (PDA) that accepts the language L5 in the previous question. Especially if you are drawing the PDA, you must explain your design in 1-2 sentences.
1. Design an automaton to accept the language ((a²b3)* :k:0})*
Construct a PDA (pushdown automata) for the following language L={0^n 1^m 2^m 3^n | n>=1, m>=1}
