List is a generic term for a collection of objects. It may or may not contain duplicates and application may or may not require that it be kept in specified order.
· Insert: Insert a new entry into a list
· Delete: Delete an entry from list
· Length: Compute length of a list
· Next: Return the next element in a list
· Search: Search if an element is in a list
Linear list: A linear list is a sequence of n>=0 nodes x[1], x[2], x[3] ……………x[n] whose essential structural properties between items as they appear in a line.
Restricted list: In restricted list, Data can only be added or deleted at the ends of a structure and processing is restricted to operations at the end of lists.
The two restricted list structures are First In First Out (FIFO) stacks and Last In First Out (LIFO) queue.
i. Insertion
ii. Deletion
iii. Retrieval
iv. Traversal
The functions defined to operate on a list are
· Delete: Delete an entry from list
· Length: Compute length of a list
· Next: Return the next element in a list
· Search: Search if an element is in a list
Restricted list: In restricted list, Data can only be added or deleted at the ends of a structure and processing is restricted to operations at the end of lists.
The two restricted list structures are First In First Out (FIFO) stacks and Last In First Out (LIFO) queue.
The four operations performed on linear lists are
ii. Deletion
iii. Retrieval
iv. Traversal
Depending on the type of linear list, an insertion can be made at the beginning of the list, or at the end of the lists. When inserting data into ordered list, the data must be inserted so that the ordering is maintained. Deletion from general lists requires that the list be searched for the data to be deleted.
List retrieval requires that data be located in a list and presented to the calling module without changing the contents of the lists.
List traversal is a special case of retrieval in which all the elements are retrieved in a sequence.
A link list is a collection of records, called nodes, each containing at least one field(member) that gives the location of the next node contains two members; a data member (the value of the list item) and a link member (a value locating the next node).The link list is a very flexible dynamic data structure. It is a low-level structure upon which high-level data structures can be built.
i. Create: Makes a new linked list
ii. Insert: Puts a new node in its place in the list.
iii. Remove: Remove a node from the list.
iv. Traverse: This function allow user to visit each node in the list.
v. Is empty: The function returns a true/false indication of whether or not there are any nodes in the list.
vi. Is full: This function returns a true/false indication of whether or not the list is full
i. Singly linked lists
ii. Circular singly linked lists
iii. Doubly linked lists
iv. Circular Doubly linked lists
Definition of Linked list
The Typical basic linked-list operations are
ii. Insert: Puts a new node in its place in the list.
iii. Remove: Remove a node from the list.
iv. Traverse: This function allow user to visit each node in the list.
v. Is empty: The function returns a true/false indication of whether or not there are any nodes in the list.
vi. Is full: This function returns a true/false indication of whether or not the list is full
Types of linked lists
ii. Circular singly linked lists
iii. Doubly linked lists
iv. Circular Doubly linked lists
