Please written by computer source This question asks you to perform competitive analysis of transpose (TR) and frequency count (FC).(i) Suppose that you are maintaining a list of n elements under access operation only. The cost of access to the i-th element in the list is i. Let S be arequest sequence of m access operations over this list. For any suﬃciently large m, construct a request sequence S such that for this request sequence, the total cost of TR divided by the total cost of MTF is ω(1).(ii) Use the result of (i) to argue that TR is not competitive.Hint: You just have to use the deﬁnition of competitiveness. Therefore, You cansolve this subquestion without having to solve (i) ﬁrst.(iii) Further prove that FC is not competitive, either.

Given two sequences X and Y, we want to find Z i.e., the longest common subsequence (LCS) of both X and Y. Because we know that subsequences of interest are of length >= a and <= b, we threshold the LCS definition to |Z| in [a, b] (where |Z| is the sequence length). In python state the recursive formula for this problem. Implement the algorithm with bottom-up approach dynamic programming and backtracking. Create an iterative function that prints the longest common subsequence(LCS).
