Question 3. Write down a regular expression that denotes the following language. L = {a mb n : m + n is even} Question 4. Let L1 be the language denoted by ab∗ a ∗ and let L2 be the language denoted by a ∗ b ∗ a Write a regular expression that denotes the language L1 ∩ L2.
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?
Question 3. Write down a regular expression that denotes the following language. L = {a^m b^n : m + n is even}
Consider the language L below. (a) Is L a regular language? – Yes, or No. (b) If L is a regular language, design the DFA (using a State Table) to accept the language L, with the minimum number of states. Assume , (c) Suppose the input is “101100”. Is this input string in the language L? Σ = {0,1} L={w l w has both an even number of O's and an odd number of 1's}
Show that the language L defined below is regular: L={w/ w has an even number of O's and 1 is the last symbol)
1. Construct a DFSM to accept the language: L = {w € {a,b}*: w contains at least 3 a's and no more than 3 b's} 2. Let acgt} and let L be the language of strings consisting of repeated copies of the pairs at, ta, cg, gc. Construct both a DFSM to accept the language and a regular expression that represents the language 3. Let a,b. For a string w E ', let W denote the string w with the...
Question 1. Let S = {a,b}, and consider the language L = {w E E* : w contains at least one b and an even number of a's}. Draw a graph representing a DFA (not NFA) that accepts this language. Question 2. Let L be the language given below. L = {a”62m : n > 0} = {1, abb, aabbbb, aaabbbbbb, ...} Find production rules for a grammar that generates L.
Let ?= (a, b). The Language L = {w E ?. : na(w) < na(w)) is not regular. (Note: na(w) and nu(w) are the number of a's and 's in tw, respectively.) To show this language is not regular, suppose you are given p. You now have complete choice of w. So choose wa+1, Of course you see how this satisfies the requirements of words in the language. Now, answer the following: (a) What is the largest value of lryl?...
Please explain the answer shortly! :) The language of the regular expression (0+10)* is the set of all strings of O's and 1's such that every 1 is immediately followed by a 0. Describe the complement of this language (with respect to the alphabet {0,1}) and identify in the list below the regular expression whose language is the complement of L((0+10)*). (0+1)*11(0+1)* (1+01)* (0+11)* (0+1)*1(8+1(0+1)*)
Prove that the following language is not regular: L = { w | w ∈ {a,b,c,d,e}* and w = wr}. So L is a palindrome made up of the letters a, b, c, d, and e.
