Question

A palindrome is a nonempty string over some alphabet that reads the same forward and backward. For instance, sequence ACGTGTCAAAATCG has palindromic subsequences, including ACGCA and CAAC, while ACG is not palindromic. Design an efficient algorithm that takes a sequence x[1 … n] and returns the longest palindromic subsequence. Give the Big-Oh characterization of your algorithm.
