    It’s a line with a sequence of two or more characters repeated at least twice.

      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.
