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