what is the difference between a linear linked list and a circular linked list?
for arrays you can list the different arrays and what attributes that you give to them.
compare difference between static and dynamic implementation of linked list.
Array is a simple sequence of numbers which are not concerned about each-others positions. they are independent of each-others positions. adding,removing or modifying any array element is very easy.Compared to arrays ,linked list is a comlicated sequence of numbers.each number in the linked list is connected to its previous & next no. via a link which is nothieng but a pointer.Addition,removal of no.s in linked list is related to this pointer direction & linking that no. to the no. which is already present in the list.
To store similar type linear data, linked list or array is used. Linked list has two major advantages over arrays which are ease of deletion and insertion and dynamic size.
I assume you are referring to implementation of Abstract Data Types like Stacks and Queues. Arrays have capacity limits which you set upon declaring them. If you have date which has a definite size, then using arrays is okay. But if you have data which size changes at runtime, then just use linked lists because linked lists could constantly add nodes whenever needed. arrays need continuous memory allocation for their creation but in linked list the memory allocation need not be continuous....
Linear linked list is a data structure where the last element is linked to a null object. With circular linked list, the last element is linked to the first element.
A singly-linked list offers forward traversal only. A doubly-linked list offers bi-directional traversal.
Typically when one refers to a "linked list" they are actually referring to a "singly linked list." Technically, however, "linked list" refers to the collection of all different implementations of linked lists: singly linked list, doubly linked list, circular linked list, circular double linked list, etc.
Linked lists take extra memory for storing the addresses. Linked lists have an access time of O(n), arrays have an access time of O(1).
A linked list implemented with an array defeats the purpose of using a linked list, which is to address the memory allocation problems associated with arrays.
You would use linked lists instead of arrays in two instances: 1) You don't know how long your list will be and it is apt to dramatically change length. 2) You will make lots of additions and removals in the middle of your list.
I would say no, but it really depends on your point of view. An array and a linked list can both hold the same data; the only difference is how they do so. The definition of a linked list is a sequence of connected nodes. An array is a contiguous block of memory, so you can think of an array as a linked list in which each element is spacially connected to the next.
Use a linked-list.
An array is a list of objects.A linked list is made up of nodes each containing a value then the pointer to the next node.Linked list exampleNode 1:dog,continued in node 4Node 2:undefinedNode 3:mouse,end of listNode 4:cat,continued in node 3Array example:dog,cat,mouse,pony,horse
A list is an abstract data structure, usually defined as an ordered collection of data. A linked list refers to a specific implementation of a list in which each element in the list is connected (linked) to the next element.
There is a difference: a pointer is a number that literally points to a place in memory. Arrays are groupings of a type. There is a close relationship between pointers and arrays, however: every expression with arrays (example: array[i]) can be expressed with pointers (example: *(array + i)), because for the computer, an array is just a list of pointers to the type of the array.
I am assuming that you are talking about Linked List and Arrays, Linked list are made up of nodes, which reference data and another node. Arrays on the other hand are just simply blocks in the memory to hold sequential data. Thus Arrays require contiguous memory (the memory allocated must be together, and increasing this allocation may need a new location, since new data may overflow to pre-existing data), while Linked Lists do not. Since Linked Lists are "linked" sequentially, there is no support for random access (all access must be traversals from the front to the desired value). Arrays are more efficient for data structures that are rarely modify (thus getting around the contiguous memory requirement), and Linked List allow efficient modification (all adds and removes are constant efficiency, while arrays must shift elements).
A singly linked list is a set of nodes where each node has a pointer to the next node. A doubly linked list is a set of nodes where each node has a pointer to the next node as well as a pointer to the previous node.
Elements of list have two pointers (instead of only one): one to access the next element, and the other for the previous one
A doubly linked list is an extension of the singly linked list in which each node also has a link to the previous node. Single: 0 -> 1 -> 2 -> 3 -> 4 Double: 0 <-> 1 <-> 2 <-> 3 <-> 4
Nodes in a Single linked list contains only one reference field (i.e. pointer to another node of linked list ) while nodes in a double linked list contains the 2 reference fields. In double linked list, one of the 2 reference field is used to point to previous node and other is used to point to next node in the linked list. so searching in single linked list is unidirectional and in double linked list it is bidirectional.
The only difference between a link list and the cursor implementation of a linked list is that the curse implementation makes it a link list with different linked node methods. A cursor implementation of linked list involves using several nodes with the "next" pointer going to the index to trigger another node in the list.
Answersingly linked list has the node inserted only at one end. and the pointer corresponds to the next pointer.but in a doubly linked list, the node pointer points to the both previous and the next node.singly linked list has two nodesdoubly linked list has three nodesA doubly linked list makes sense when you need to traverse the list in both directions. You aren't able to do that with a singly linked list.
A linked list must start from the root node, and can only travel in a single direction (via a next pointer/reference), while a doubly-linked list can travel both forwards and backwards through the list (through the use of a next and previous pointer/reference).
