Essential algorithms for GCSE and A Level Computer Science
Higher order data structures
Supported by some programming languages within the command set, programmers often implement these structures using the fundamental data structures as building blocks.
What is a linked list?
A linked list is a data structure that provides a foundation upon which other data structures can be built such as stacks, queues, graphs and trees. A linked list is constructed from nodes and pointers. A start pointer identifies the first node. Each node contains data and a pointer to the next node in the linked list. Many programming languages support lists in addition to arrays.
Data in lists can be stored anywhere in memory, with pointers indicating the address of the next item in the structure.
