Then why is this sequence considered contiguous? how is the contiguousness defined?

  • 1

    From the known cases, the sequence of 2 , -3 , 1 , 2 , 3 , -2 is considered contiguous, so is -1, 1, it seems to me that zero is omitted, and duplicates are allowed, so, what is the requirement?

  • 0

    Contiguous means the numbers are adjacent in the given array, indexed 3 to 8;
    This has nothing to do with the value of the numbers themselves.
