LongestCommonSubsequence

LongestCommonSubsequence[s1,s2]

finds the longest contiguous subsequence of elements common to the strings, biomolecular sequences or lists s1 and s2.

Details and Options

  • If there are several common subsequences of the same length, LongestCommonSubsequence returns the one that appears earliest in s1.
  • For strings, setting the option IgnoreCase->True makes LongestCommonSubsequence treat lowercase and uppercase letters as equivalent, and return the form of common subsequence that occurs in s1.
