LongestCommonSubsequence

LongestCommonSubsequence
finds the longest contiguous subsequence of elements common to the strings or lists and .
  • If there are several common subsequences of the same length, LongestCommonSubsequence returns the one that appears earliest in .
  • 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 .
