-[LinkedList]s work by each node merely pointing to the next node in the list, where the last node has a NullPointer. Doubly-linked lists have a previous pointer as well, allowing bi-directional iteration. A circular list has the last node pointing back to the first node. Adding and deleting nodes aren't terribly complex but require a little thinking; you need to store temporary pointers and do a little magic. Most higher level languages have linked list constructs. For example [C++] has the [STL], [Java] has a LinkedList in its class libraries. If you are coding C, however, you might have to write your own.

Most higher level languages have linked list constructs. For example [C++] has the [STL], [Java] has a LinkedList in its class libraries. FunctionalLanguages almost always have linked lists as built-in datatypes, the linked list is the primary datatype in [Lisp]
. If you are coding [

, however, you might have to write your own.

+''Note'': Python has a "list" datatype, but it is implemented as an array of pointers, so don't treat it like a linked list -- prepending elements to the head of a Python list one by one is not an efficent thing to do
.
