this question is from the subject data structure and i need answer of this. data structure is the subject ot 3rd semester of bachelor's degree
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.
To delete a linked list walk through the list and delete the memory allocated to each element, remembering the next element address, and then iterating or recursing the process using the next element address, until the next element address is null.
You copy a singly linked list into a doubly linked list by iterating over the singly linked list and, for each element, calling the doubly linked list insert function.
To search for an element in a linked list, you iterate the list, looking for the element, and either return the element or an indication that it was not found. for (ptr = first; ptr != null; ptr = ptr.next) if (ptr.value == searchvalue) break; This will either leave ptr with the address of the found element, or null, if not found.

Linked list of strings, for example.
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.
The time complexity of inserting an element into a linked list is O(1) or constant time.
The time complexity to find an element in a linked list is O(n), where n is the number of elements in the list. This means that the time it takes to find an element in a linked list increases linearly with the number of elements in the list.
A circular linked list is just a linked list in which the last element of the list is connected to the first element, so if you followed the links, you'd be following them in a circle forever.
With pointers pointing 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.
A linked list is a set of elements, usually structures, where each element contains a pointer or index to the "next" element, along with the data represented by the element.Often, the elements are allocated from the heap. Sometimes, a fixed number of elements is contained in an array. In the first case, pointers are used. In the second case, indices are used.Types of linked lists are ... In an array implementation, read pointer as index.Singly linked - there is a head pointer, and one next pointer per element. The last element's pointer is null. This type of list can be traversed in only one direction.Doubly linked - there is a head pointer, and each element contains two pointers, one to the previous element and one to the next element. This type of list can be traversed in two directions, making insertion and deletion a bit easier, at the cost of extra memory.Circularly linked - the same as Singly or Doubly linked, except that the last element's pointer points back to the first element's pointer. These types of lists are often used as queues.
