Question

In specifying the ADT list, you would have:

1) A set of operations that can be performed on the list
2) A set of data elements that make up the list
3) A way to store the list in memory
4) A way to access and manipulate the elements in the list

Answer 1

The question pertains to defining a list as an Abstract Data Type in computing, which includes a set of operations, data elements, storage methods, and access/manipulation mechanisms, without specifying the internal implementation details.

Step-by-step explanation:

The subject in question relates to the abstraction of a list data structure in computing, specifically the concept of an Abstract Data Type (ADT). ADT is a model for data types where the data type is defined by its behavior from the point of the user. In specifying the ADT list, the elements you've mentioned are crucial.

1. A set of operations that can be performed on the list: This includes methods to add, remove, or retrieve items from the list. Examples might be append, insert, delete, and get.
2. A set of data elements that make up the list: The actual items stored in the list, which could be integers, strings, objects, etc.
3. A way to store the list in memory: This relates to how the list is structured internally—such as an array or linked list implementation.
4. A way to access and manipulate the elements in the list: This involves lookup methods, like indexing or iterators, which allow traversal and modification of the list's elements.

The ADT does not specify the concrete implementation but provides an interface by which the list operates. Thus, the implementation details, like memory allocation and algorithms for each operation, are hidden from the user, ensuring the separation of the interface from the underlying implementation.
