Create a PDA that recognizes the language described. 1. {0n1m | n≠m} 2. {0n1m | m=2n} 3. {0^n1m | n≤m≤3n} 4. {w | w∈{0,1}∗,num of 0's in w=2(num of 1's in w)}
1(a)Draw the state diagram for a DFA for accepting the following language over alphabet {0,1}: {w | the length of w is at least 2 and has the same symbol in its 2nd and last positions} (b)Draw the state diagram for an NFA for accepting the following language over alphabet {0,1} (Use as few states as possible): {w | w is of the form 1*(01 ∪ 10*)*} (c)If A is a language with alphabet Σ, the complement of A is...

Problem 1. From a language description to a PDA Show state diagrams of PDAs for the following languages: a. The set of strings over the alphabet fa, b) with twice as many a's as b's. Hint: in class, we showed a PDA when the number of as is the same as the number of bs, based on the idea of a counter. + Can we use a...
Construct a PDA (pushdown automata) for the following language L={0^n 1^m 2^m 3^n | n>=1, m>=1}
3. [20 points] Give short answers to each of the following parts. Each answer should be at most three sentences. Be sure to define any notation that you use. (a) Explain the difference between a DFA and an NFA. (b) Give a regular expression for the language consisting of strings over the alphabet 2-(0, 1) that contains an even number of 0's and an odd number of 1's and does not contain the substring 01. (c) Give the formal definition...
Prove that for two machines M and N, M indistinguishable from N does not imply that M has the same behavior as N. Hint: one way to prove this is to exhibit two machines, a two state machine M and a three state machine N, both over X = {0,1} and Y = {0,1} with this property
Consider two 2-bit inputs labelled M1, M0, N1, N0 and an output labelled F. Draw a gate-level schematic for the following combinational logic: F = M > N. Include the truth table and simplification method in your answer.
. Please design a standard TM (i.e., a single semi-infinite tape, deterministic) for the laın guage of all palindromes over alphabet {a, b} . Please give both the high-level description (text description or pseudo-code algorithm) and the low-level state transition diagram. Please analyze how many steps (one transition is considered as a step) it takes to accept an input palindrome with n symbols . Please design a deterministic Turing machine with two semi-infinite tapes for the same language. Please give...
