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.
pseudo code algorithm to create a linked list
Advantages of single linked list: # Decrease in storage space per linked list node # Simpler implementation Advantages of double linked list # Decrease in work when accessing a random node # Decrease in work when inserting or deleting a node
theory part to how u can insert element at middle of link list ?
A doubly linked list can be traversed in both directions (forward and backward). A singly linked list can only be traversed in one direction. A node on a doubly linked list may be deleted with little trouble, since we have pointers to the previous and next nodes. A node on a singly linked list cannot be removed unless we have the pointer to its predecessor. On the flip side however, a doubly linked list needs more operations while inserting or deleting and it needs more space (to store the extra pointer).
It depends on whether or not you have a head node. If you do, then it is not a special case. If you don't, then it is, and you need to be able to update the head pointer.

In linked list, there are various operations in linked list that you can perform on linked list, eg: adding new elements, deleting elements, getting the first element, getting the next element after an element, any many others.

Insert newNode into a linked list after targetNode Node currentNode = root while currentNode != targetNode currentNode = currentNode.next newNode.next = currentNode.next currentNode.next = newNode
Linear time. O(n).

To efficiently sort a doubly linked list, you can use a sorting algorithm such as merge sort or quicksort. These algorithms can be implemented to work with doubly linked lists by considering the pointers in both directions. By recursively dividing the list and merging or partitioning the elements, you can achieve an efficient sorting process.
To determine if a linked list is circular, you can use the Floyd's cycle detection algorithm. This algorithm involves using two pointers moving at different speeds through the list, and if there is a cycle, the two pointers will eventually meet at the same node. If they don't meet and one of the pointers reaches the end of the list, then the list is not circular.
It depends on whether or not you have a head node. If you do, then it is not a special case. If you don't, then it is, and you need to be able to update the head pointer.
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.
