QUESTION 12 Consider the regular expression (a+b)'cdb Which of the following strings is not a part of the regular expression ? ababcabcd abaabbbcdbb aaaaacd cd
Which of the following strings would match the regular expression: [a-z]+[\.\?!] A. Shout! B. Cry C. weep.? D. Laugh E. smile? What is the answer and why. go through each expression please. eg what does\. do \?! do etc
Give a regular expression for the language of strings over {a,b} in which each substring of length 2 contains two distinct characters
(a) Give 2 strings that are members of language specified by the regular expression (0+ 1)∗ but are not members of the language specified by 0∗ + 1∗ . Then give 2 strings that are members of both languages. Assume the alphabet is Σ = {0, 1}. (b) For each of the following languages specified by regular expressions, give 2 strings that are members and 2 strings that are not members (a total of 4 strings for each part). Assume...
construct an nfa for the regular expression (ac)*(b|cd).
(4 points.) Consider the regular expression (11 + 00)'1(e + 01). . Give two strings of O's and 1's, each 6 to 12 characters long, that are both represented by this regular expression . Construct a nondeterministic finite automaton equivalent to the regular expression. (4 points.) Consider the regular expression (11 + 00)'1(e + 01). . Give two strings of O's and 1's, each 6 to 12 characters long, that are both represented by this regular expression . Construct a...
How to change regular expression to regular grammar? Please give me with details and explain me with easy ways. For instance (10*)*(110v001)* Binary strings contain substring 1001 Binary bring contains exactly two zeros
Find a regular expression for the following language over the alphabet Σ = {a,b}. L = {strings that begin and end with a and contain bb}.
Provide a regular expression for the following languages: (a) the set of all strings over {a, b} that start with ab and end with ba, (b) the set of strings over {a, b} where four consecutive occurrences of both letters occur in every word.
Write a regular expression that captures the set of strings composed of 'a', 'b', and 'c', where any string uses at most two of the three letters (for example, "abbab" is a valid string, or "bccbb", or "ccacaa", but not "abccba": strings that contain only one of the three letters are also fine). Give a non-deterministic finite automaton that captures the regular expression from Using the construction described in class, give a deterministic version of the automaton. Repeat the previous...
