Topic: Linked list



  
 Linked list - Wikipedia, the free encyclopedia
In computer science, a linked list is one of the fundamental data structures used in computer programming.
Each node has two links: one points to the previous node, or points to a null value or empty list if it is the first node; and one points to the next, or points to a null value or empty list if it is the final node.
IPL was used by the authors to develop several early artificial intelligence programs, including the Logic Theory Machine, the General Problem Solver, and a computer chess program.

 linked list - Webopedia.com
Linked list data storage works best with data arrays in which one doesn’t know how large the array will need to be or when there is a certainty of more data being added or subtracted at later times.
A disadvantage to linked list data storage is that the data must be accessed sequentially and cannot be accessed randomly.
Some common applications of linked lists include creating hash tables for collision resolutionn across communication channels, structuring binary trees, building stacks and queues in programming, and managing relational databases.

 Linked List Tutorial
The singly linked list is a convenient way to store an unbounded array, that is create an array where one doesn't know in advance how large the array will need to be.
The data structure describing the singly linked list is defined by the following code.
A pointer is initialized to the list root.

 Cprogramming.com Tutorial: Linked Lists
Linked lists are a way to store data with structures so that the programmer can automatically create a new place to store data whenever necessary.
It works the same way in the while loop.) Therefore, conductor->next is set to null, so it is okay to allocate a new area of memory for it to point to.
Bad for the conductor (if it were a real person), but the code is simpler as it also allows us to remove the initial check for null (if root is null, then conductor will be immediately set to null and the loop will never begin):

 Chapter 14: Linked lists
The reference of the third node is null, which indicates that it is the end of the list.
For example, we might represent a number as a list of digits and use an infinite list to represent a repeating fraction.
A natural choice for the base case is a list with a single element, but an even better choice is the empty list, represented by null.

 [No title]
For example, it is possible to maintain a linked list in a sorted state, and hold pointers to elements in the list, while adding data to the list.
A topic that is often addressed in introductory computer science courses is the design and implementation of a linked list.
Another implementation issue is that copying a singly linked list requires a function to reverse the list, because the obvious strategy of iterating over the nodes and inserting them gives us a list in the wrong order.

 Linked List Tutorial
Singly linked lists are useful data structures, especially if you need to automatically allocate and de-allocate space in a list.
Sorting linked lists can be a chore, but with careful selection of sorting algorithms, nearly constant time can be acheived.
The code and complexity of these algorithms is bigger, but the tradeoff is ease of use.

 Developing for Developers : Unrolled linked lists
Today I'll be discussing unrolled linked lists, a simple variant of the linked list which has many of its desirable properties but exploits the cache to yield considerably better performance on modern PCs.
In elementary data structures classes, students are often taught about arrays and linked lists and the algorithmic tradeoffs between the two.
If a cache line has size B, then the number of cache misses is about n/B. A linked list, on the other hand, requires a cache miss for every node access in the worst case.

 Linked Lists
A linked list is an algorithm for storing a list of items.
To implement this list, you would also want to store a pointer to the first item in the list (the head), which you would use to access the other items.
I've received a lot of questions about linked lists and so, this month, I thought I'd present a bit of code that implements a linked list.

 Linked List Representation
From an implementation perspective, adding this is slightly more clumsy than it might appear, because the linked list that represents the row array is a linked list of linked lists, while the linked list that represents each row itself is a linked list of whatever type of element the array actually represents.
Of course, it is possible to represent the array using both methods: an array of row lists, and an array of column lists.
For example, if we represent our sparse array with an array of rows (where each row is a linked list), then determining whether or not a particular row is entirely empty is an O(1) operation- either the pointer in the row array is NULL, or it isn't.

We could also use it as a master listing of items that need to be kept track of at one time, deleting object when they need to be, without using any precedence scheme.
Likewise if we are at the end of the list and try to advance to the next node (nothing), it doesn't move our pointer.
Linked lists form the foundation of many data storing schemes in my game!

 Java 2 Platform SE v1.3.1: Class LinkedList
If the list fits in the specified array with room to spare (i.e., the array has more elements than the list), the element in the array immediately following the end of the collection is set to null.
Otherwise, a new array is allocated with the runtime type of the specified array and the size of this list.

 Encyclopedia article on Reference [EncycloZine]
In computer science, references are datatypes which refer to an object elsewhere in memory, and are used to construct a wide variety of data structures such as linked lists.
Most programming languages support some form of reference.

 Linked list - DmWiki
However, if you have data that you will only be accessing in order, it is very fast, because you don't have to look up the item each time you just use a loop, or a recursive function, to follow the next pointer each time.
Making sure to set the next pointer to NULL so that we know that this Type item has no next item.
At its most basic level, a linked list is a data structure consisting simply of a series of node structures, which are linked to each other.

 Xor linked list - Wikipedia, the free encyclopedia
Xor linked lists are a curious use of the bitwise exclusive disjunction (XOR) operation to decrease storage requirements for doubly-linked lists.
The pointers will be unreadable if one isn't traversing the list - for example, if the pointer to a node was contained in another data structure.
Where it is still desirable to reduce the overhead of a linked list, unrolling provides a more practical approach (as well as other advantages, such as increasing cache performance and speeding random accesses).
