This simple structure is most commonly used to build singly linked lists, but can also be used to build simple binary trees and so-called " dotted lists ", which terminate not with a null reference but a value.

The stored address is called before or after the TSR has received the interrupt and has finished its processing, in effect forming a singly linked list of interrupt handlers, also called " interrupt service routines ", or ISRs.

I've reduced the CPU usage of a program from 100 % ( and dying, i . e . falling farther and farther behind in its processing of real-time events ) to 2 % by moving the event queue from a singly linked list to a skip list.

For example, given " N " sequence data structures, e . g . singly linked list, vector etc ., and " M " algorithms to operate on them, e . g . find, sort etc ., a direct approach would implement each algorithm specifically for each data structure, giving combinations to implement.

While adding or removing a node in a doubly linked list requires changing more links than the same operations on a singly linked list, the operations are simpler and potentially more efficient ( for nodes other than first nodes ) because there is no need to keep track of the previous node during traversal or no need to traverse the list to find the previous node, so that its link can be modified.

Several iterator concepts are specified in the STL, each a refinement of more restrictive concepts e . g . forward iterators only provide movement to the next value in a sequence ( e . g . suitable for a singly linked list or a stream of input data ), whereas a random-access iterator also provides direct constant-time access to any element of the sequence ( e . g . suitable for a vector ).
