A B-bounded PDA (pushdown automaton) is a PDA M such that it crashes whenever its stack height reaches B. Show that the language {0n1n : n ≥ 1} can not be accepted by a B-bounded PDA for any B.

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.
6. Create a single stack pushdown automaton that represents/accepts this regular expression. Where m>p
2. [10 marks] Give a PDA (Pushdown Automata) that recognizes the language L = {o€ {n,y, z}* | 2|이|z = |0ly V 2\이 You can choose whether your PDA accepts by empty stack or final state, but make sure you clearly note, which acceptance is assumed 2.

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.
Please Help with this questions with short explanation thank you :) Consider the pushdown automaton with the following transition rules: 1.8(0,0,20) = {(q,XZ0)} 2. 8(9,0,X) = {(q,XX)} 3. 8(q,1,X) = {(q,x)} 4. 8(q,£,X) = {(p,ɛ)} 5. 8(p,£,X) = {(p,ɛ)} 6.8(p,1,X) = {(p,XX)} 7. 8(p,1,20) = {(p,ɛ)} From the ID (p,1101,XXZ0), which of the following ID's can NOT be reached? (p,101,XZO) (p,101,XXXZO) (2,01,XXXXXZO) O (p,01,8) Here are the transitions of a deterministic pushdown automaton. The start state is qo, and f...
Construct a PDA (pushdown automata) for the following language L={0^n 1^m 2^m 3^n | n>=1, m>=1}
Q1) Consider the following push down automaton (PDA). wak READ, PUSH bREAD ACCEPT READ,ab REJECT b) What is the language accepted by this PDA?
6. Consider a Pushdown Automata with TWO STACKS. Show that this machine is more powerful than a single stack PDA. (Use the language L = {a"\"c"which is not a CFL. Explain bow a two stack automata can accept this language.) HINT : Give a table representation of the 2PDA - it should have 7 columns : state, input, stack 1, stack 2, new state, stack 1 operation, stack 2 operation.
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}*}
4. Show that the pda constructed in Example 7.6 accepts the strings aabb and aaabbbb, and that both strings are in the language generated by the given grammar. EXAMPLE 7.6 Construct a pda that accepts the language generated by a grammar with productions We first transform the grammar into Greibach normal form, changing the productions to A bB, The corresponding automaton will have three states (go, 91,92), with initial state go and final state q2. First, the start symbol S...
