finds the longest sequence of contiguous or disjoint elements common to the strings or lists and .

Details and OptionsDetails and Options

  • LongestCommonSequence returns the longest common sequence with disjoint pieces concatenated.
  • If there are several common subsequences of the same length, LongestCommonSequence returns the one that begins earliest in .
  • For strings, setting the option IgnoreCase->True makes LongestCommonSequence treat lowercase and uppercase letters as equivalent, and return the form of common sequence that occurs in .
