Concepts and relationships

  • Data Structures include Array.
  • Data Structures include Linked List.
  • Data Structures include Stack.
  • Data Structures include Queue.
  • Data Structures include Tree.
  • Data Structures include Hash Table.
  • Stack built on Linked List.
  • Queue built on Linked List.

How to read this map

See the main structures branch from the centre, and how stacks and queues can be built on linked lists.

Learning objectives

  • Name the core data structures.
