1. (10 pts) Longest Common Subsequence (LCS) Given two sequences X[1...n) and Y[1m], compute the longest common subsequence of X and Y using dynamic pro- gramming. Let D[][] be the maximum length of the common subsequence of X[1] and Y[1]. Answer the following: a) What is the recurrence equation for D[i][j]? b) What is the base case? c) Given X="ATTGA" and Y = "ATGTAA". Fill in the dynamic programming table to compute D[i][j]. d) What is the actual longest common subsequence of the above example? You MUST show the tracing in the dynamic programming table to receive full credit. You only need to show one answer even if multiple solutions exist.
