Constuct NFAs for the following. ∑ = {0,1} 1) The language a(abb* + b ) +...
Exercise 2: Find the NFAs that accepts the following regular expressions: The language (10 u 110)* The language Σ*0012 -
For the following grammar (7 points) 1. B - Ba|A S - ABb A - Aba |A to find a grammar without A productions that generates the same language, we first identify non-terminals that drive A. These non-terminals are: A and B. Then from S - ABb, we construct S from A - Aba, we construct A - from B - Ba, we construct B - So, the grammar without A that generates the same language is:
Find a dfa that accept the following language L((aa∗)∗ + abb)
Give a six-state (including dead state) DFA for the language {w ∈ {a,b}*: w contains abb as a substring, and does not contain bba}
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...
QUESTION 8 For the following equation, solve for the language L. {a, aa, ab} L = {ab,aab,abb, aa aaa, aba} O L = {bb,aa,a} O L = {b,a} O L = {b,aa} L = {4,b,a} QUESTION 9 Consider the regular expression (a+ab)*(b+ab)* Which of the followings

1. Construct a Finite Automata over Σ={0,1} that recognizes the language {w | w ∈ {0,1}* contains a number of 0s divisible by four and exactly three 1s} 2. Construct a Finite Automata that recognizes telephone numbers from strings in the alphabet Σ={1,2,3,4,5,6,7,8,9, ,-,(,),*,#,}. Allow the 1 and area code prefixing a phone number to be optional. Allow for the segments of a number to be separated by spaces (denote with a _ character), no separation, or – symbols.
