Overview
A list is an implementation of a dynamic set.
Linked Lists
A linked list is a data structure implementing a dynamic set in which the elements are arranged in a linear order. The order is determined by pointers maintained by elements to other elements in the list. All dictionary operations (INSERT, DELETE, SEARCH) can be implemented for a list.
A simply linked list has elements that maintain a next pointer to the next element in the list. The last element's next pointer contains NULL.
A doubly linked list has elements that maintain a next pointer to successor in the list and a prev pointer to the predecessor in the list.
