The problem is usually defined as: Given two … If there are multiple common subsequences with the same maximum length, print any one of them. Longest Common Subsequence The Longest Common Subsequence (LCS) problem is one where you're trying to find the longest sequence in common between two sequences. We also show that this problem is APX-hard. Fluctuations of the longest common subsequence for sequences of independent blocks Heinrich Matzinger Felipe Torresy June 4, 2018 Abstract The problem of the order of the uctuation of the Longest Common Subsequence (LCS) of two independent sequences has been open for decades. n2 = store length of string s2. In case multiple solutions exist, … (eg, "ace" is a subsequence of "abcde" while "aec" is not). Given two sequences X = hx1;x2;:::;x miand Z = hz1;z2;:::;z ki, we say that Z is a subsequence of X if there is a strictly increasing sequence of k indices hi1;i2;:::;i ki(1 i1
