Chapter 17.2, Problem 17.9CP
Explanation of Solution
Linked list:
Linked list is a linear and dynamic data structure which is used to organize data; it contains sequence of elements which are connected together in memory to form a chain. The every element of linked list is called as a node.
Deleting a node from a linked list:
Deleting a node from a linked list is the process of removing a node from the linked list.
Steps to delete a node:
There are two steps to delete a node from a linked list, which are as follows:
- Remove the node from the list without breaking the links created by the next pointers.
- To delete particular value from the linked list without breaking the links, connect the address link of previous node to the node that is available at next to the node that required to be deleted...

Assume that there is a linked list that connected several names.How do you delete the "Brandon" node?
You must use assignment statements to update your memory boxes
True/False Select true or false for the statements below. Explain your answers if you like to receive partial credit.
3) Which of the following is true about the insertBeforeCurrent function for a CircularLinked List (CLL) like you did in programming exercise 1?a. If the CLL is empty, you need to create the new node, set it to current, andhave its next pointer refer to itselfb. The worst case performance of the function is O(n)c. If you insert a new element with the same data value as the current node, theperformance improves to O(log n)
How many references must you change to insert/delete a node in a single/double linked list? What are the time complexities of finding 10000th element from beginning of a linked list of size n? Understand the method such as AppentToHead, AppendToTail, Delete,...etc and be able to answer questions based on certain scenario?

- True or False For each statement below, indicate whether you think it is True or False. If you like, you can provide a description of your answer for partial credit in case you are incorrect. 4) Delete is O(1) in the worst case because there is no shift after removing the node 5) Update is O(n) because it needs to perform a search for the element in the list 6) In the delete algorithm, the “previous” node reference is needed in case the element is not found in the listarrow_forwardThe programming language is Python Instructions: Create a function that will delete a node in a Linked List based on position number.
