LINEAR STRAIGHT CIRCULAR CURVED
I would say that there is no such thing as a circular queue. The point of a circular data structure is to allow the end to loop around to the beginning. Since you can only remove items from the beginning of a queue or add them to the front, having these two items linked has no purpose nor benefit.
In a circular linked list every node is connected to another node. In a non-circular linked list. There are definitely starting and ending nodes are lacking an incoming and outgoing link, respectively.
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.
A doubly linked list is a linked list in which each node knows where both of its neighbors are.A circular linked list is a linked list in which the "tail" of the list is linked to the "root". (Note that both the tail and root of the list are undefined/arbitrary in a circular linked list)Doubly linked lists are actually not necessarily related to circular linked list (aside from both being based on a linked list structure). In fact, you can have a circular doubly linked list, where each node knows where both of its neighbors are andwhere the list wraps around to connect to itself.
What is the difference between linear and circular queue? In: http://wiki.answers.com/Q/FAQ/2545-37 [Edit categories]The Queue by Default is Linear, it would be termed as Circular if the Last Element of the Queue pointsto the first element of the List
A queue can use a dynamic array, or a linked list, but if using static memory, the queue becomes a circular queue because the underlaying data structure is a static circular array. This means the ends of the array are attached.
A regular linked list will have a pointer to the start of the list, with each node pointing to the next node, and finally the last node points to NULL. In a circular linked-link, the last node will point to the first node, making the list circular. This requires extra checks to ensure that you don't end up going into an infinite loop while traversing the list.
if the last node contains the address of head node instead of null then it is a circular linked llist...
A linked list is circular if the tail of the list points to the head. The easiest way to check this is to check whether the pointer of the tail is a null pointer. If it is, then the list is not circular.
they have different meanings
The Josephus problem is a problem to locate the place for the last survivour. It shows the power of the circular linked list over the singly linked lists.
Circular 38b, linked below, is a summary of amendments made as a result of GATT.
