(d) Let L be any regular language. Use the Pumping Lemma to show that In > 1 such that for all w E L such that|> n, there is another string ve L such that lvl <n. (4 marks) (e) Let L be a regular language over {0,1}. Show how we can use the previous result to show that in order to determine whether or not L is empty, we need only test at most 2" – 1 strings.

1. (Non-regular languages) Prove that the following languages are not regular. You may use the pumping lemma and the closure of the class of regular languages under union, intersection, complement, and reverse (b) L2 = { w | w ∈ {0, 1}* is not a palindrome }. A palindrome is a string that reads the same forward and backward
Use the pumping lemma to show that the following language is non-regular: [a"b2n,n> 1) 1) usually we need to find a word in the language as an example, what length of the word we should use as the example? what are the three possible ways to choose substring y in the pumping lemma? if a language satisfy the pumping lemma, is this language a regular language? Why?
Prove the following language is not regular (you may use pumping lemma and the closure of the class of regular languages under union, intersection, and complement.): (w | w ∈ {0,1}* is not a palindrome} Please show work/explain. Thanks.
Use the pumping lemma to show that the following language is not regular: L = {bi ajbi : i, j ≥ 1}
John Doe claims that the language L, of all strings over the alphabet Σ = { a, b } that contain an even number of occurrences of the letter ‘a’, is not a regular language. He offers the following “pumping lemma proof”. Explain what is wrong with the “proof” given below. “Pumping Lemma Proof” We assume that L is regular. Then, according to the pumping lemma, every long string in L (of length m or more) must be “pumpable”. We...
show that language L4 = { wabw : w ∈ {a,b}* } is not regular, use pumping lemma
1. Let L = {ambm cn | m <n}. Use the pumping lemma to show that L is not a CFL.
10 punts Use the Pumping Lemma to show that the the following language is not CF { xxn20AXE (a.b)* } Notice that this language is not the language of all strings with n characters from (a,b) on the left of the cand another n characters to the right of it. This language requires the same string to be repeated on both sides of the 'c. For example, if abbacabba and abbaabbacabbabba are both in the language using x = abbay,...
