4. Pumping Lemma for Regular Languages Here are three incorrect statements of the Pumping Lemma for regular languages. In each case, explain why the statement is not correct. Try to identify the most serious problem. (a) Suppose L is a regular language over the alphabet . Then the following property must be true. For every string wL, there exists a constant n such that wn, and it is possible to write w as w=xyz such that i. y= ii. xyn and iii. for every integer k0, the string xykz is also in L. (b) Suppose L is a regular language over the alphabet . Then there exists a constant n and a string wL such that wn, and it is possible to write w as w=xyz such that i. y= ii. xyn and iii. for every integer k0, the string xykz is also in L. (c) Assume L is regular. Let n be the constant mentioned in the Pumping Lemma for Regular Languages. Choose a string w such that wL and wn, and get a contradiction by showing that it is not possible to write w as w=xyz such that i. y= ii. xyn and iii. for every integer k0, the string xykz is also in L
