Based on the pumping lemma, if L is regular, then 3k > 1 (V strings w E L, where |w| >k (3x, y, z (w = xyz, |xy| ≤k, ye, and Vq ≥ 0 (xyz is in L)))). The correct statements are: For L = ab* ab, let k = 2 and every string w in L with |w| >k must be pumpable. | For L = ab*ab, let k = 3 and every string w in L with |w| >k must be pumpable. For L = ab* ab, let k = 4 and every string w in L with |w| >k must be pumpable. For L = ab* ab, let k = 5 and every string w in L with |w|> k must be pumpable.

Given two strings X and Y, where X consists of the sequence of symbols X1, X2, Xm and Y consists of the sequence of symbols y₁,Y2, ***,yn. Consider the sets {1, 2, ..., m} and {1, 2, ..., n} as representing the different positions in the strings X and Y, and consider a matching of these sets, where a matching is a set of ordered pairs with the property that each item occurs in at most one pair. A matching M of these two sets is an alignment if there are no "crossing" pairs: if (i,j). (i*,j') = Mandi 0 that defines a gap penalty. For each position of X or Y that is not matched in M (it is a gap), we incur a cost of 8. Second, for each pair of letters p and q (p + q) in our alphabet, there is a mismatch cost of app for lining up p with q. Thus, for each (i,j) = M, we pay the appropriate mismatch cost axiy for lining up x; with y;. The cost of M is the sum of its gap and mismatch costs, and the problem seeks an alignment of minimum cost. Define the minimum alignment cost OPT(i,j) (0 ≤ i ≤…
We consider certain strings of length 6 over the alphabet S = {A,B,C}. We require that the string contains exactly two As, and exactly two B's, and exactly two C's. How many such strings are there? That is, how many strings of length 6 over the alphabet {A,B,C} contains exactly two A's, two B's and two C's?
