[[File:Substring.png|thumb|'<nowiki/>"''string''<nowiki/>'" is a substring of '<nowiki/>"''substring''<nowiki/>'"]]

A '''substring''' is a contiguous sequence of characters within a [[String (computer science)|string]]. For instance, "''the best of''" is a substring of "''It was the best of times''". This is not to be confused with [[subsequence]], which is a [[generalization]] of substring. For example, "''Itwastimes''" is a subsequence of "''It was the best of times''", but not a substring.
