Give a regular expression for these languages i) {w| w is a word of the alphabet = {0,1} that represents an integer in a binary form that is a multiple of 4} ii) {w belongs to {0,1,2}* | w contains the string ab exactly 2 times but not at the end} iii) { w belongs to {0,1,2}* | w=uxvx that x belongs to {0,1,2} u,v belongs to {0,1,2}* and there isn't any string y in the sequence v that x<y}

Give regular expressions generating the languages of 1. {w over the alphabet of {0, 1} | w is any string except 11 and 111} 2. {w over the alphabet of {0, 1} | w contains at least two 0’s and at most one 1} 3. {w over the alphabet of {0, 1} | the length of w is at most 9} 4. {w over the alphabet of {0, 1} | w contains at least three 1 s} 5. {w over...
Give the regular expressions of the following languages (alphabet is ab): a. {w | w has a length of at least three and its second symbol is a b} b. {w | w begins with an a and ends with a b} c. {w | w contains a single b} d. {w | w contains at least three a's} e. {w | w contains the substring baba} d. {w | w is a string of even length} e. The empty...
Solve Regular expression to epsilon-NFA problem For the following regular expression: (((00)*(11))|01)* Over the alphabet {0,1} Give an epsilon-NFA that recognizes the same language. HELP: Block Canvas Tutorial
L = {w|w contains the substring bab} give the regular expression that describes L are the 2 languages L and L* the same language? Is L(aba)* a regular language?
1. Given L = { w∈ {0,1}* | w doesn't contains 111 }, provide a regular expression. 2.Given L = { w∈ {0,1}* | w contain 111 }, provide a regular expression. 3.Given L = { w∈ {0,1}* | w begins with 00 and ends with 1 }, provide a regular expression.
. Terminals: • Any character from the alphabet is a terminal . Epsilon (E) is expressed as: le, leps or lepsilon The empty set is expressed as: lemp or lemptyset • Operations (R is a regular expression) o Union is expressed as RIR o Star as R* o Concatenation as RR o Plus as R+ Problem For the following regular expression: (Elab Over the alphabet: {a,b} Give 2 words that the regular expression recognizes and 3 words that the regular...
4.[10 points] Let A be the language over the alphabet E-(a, b} defined by regular expression (ab U b)*a U b. Give an NFA that recognizes A. Draw an NFA for A here.

************Theory of Computing ***************** 1. Generate a regular expression of “all words over the alphabet Σ = {a b} that either begin with a and end with b OR begin with b and end in a.” Thus, the first few shortest words in this language are “ab” “ba” “aab” “baa” “abb” “bba” “aaab” etc. So, if a word begins with a it must in end b, and if it begins with b it must end in a. 2. Consider the...
