The Sequence interface

(No version information available, might only be in Git)

Giriş

A Sequence describes the behaviour of values arranged in a single, linear dimension. Some languages refer to this as a "List". It’s similar to an array that uses incremental integer keys, with the exception of a few characteristics:

  • Values will always be indexed as [0, 1, 2, …, size - 1].
  • Only allowed to access values by index in the range [0, size - 1].

Use cases:
