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...
Basic compiler question: Construct a regular expression for the regular language representing the set of strings where the number of b’s is a multiple of 3 and there can be any number of a’s. The alphabet is {a,b}
construct an nfa for the regular expression (ac)*(b|cd).
Provide a regular expression for the set of strings over {a, b, c} such that the number of a’s equals the number of b’s and is less than or equal to 2.
(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.

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}.
