> In addition, the last number of the sequence indicates the count of the members. This is only the case for 1..N, not for I..J, when 'I' is not one. In this general case, the number of elements is 'J-I' if using zero-based numbering and exclusive upper bounds, which is more convenient. Zero-base also simplifies index arithmetic with modulo operations, such as when you are mapping between different index spaces.
