    Only the part after the pipe character. The pipe character works as an “or” operator. RegalPotoo is right.

      They said—

      A line with exactly 0 or 1 characters, or a line with a sequence of 1 or 3 or more characters, repeated at least twice

      Note—

      …or a line with a sequence of 1 or 3 or more characters, repeated at least twice

      It should be—

      …or a line with a sequence of 2 or more characters, repeated at least twice

      The regex in the post will match “abab”. Their original description (line 2 of this comment) will not match “abab”.

        I agree, you’re right about the part after the pipe and RegalPotoo’s explanation was not entirely correct.
