Circular linked list is a form of the linked list data structure where all nodes are connected as in a circle, which means there is no NULL at the end. Circular lists are generally used in applications which needs to go around the list repeatedly. struct Node * insertTONull (struct Node *last, int data) // This function is only for empty list 11 5 15 struct Node insertStart (struct Node +last, int data) In this question, you are going to implement the insert functions of a circular linked list in C. The Node struct, print function and the main function with its output is given below: struct Node { int data; struct Node *next; }; struct Node insertEnd (struct Node *last, int data) void print(struct Node *tailNode) struct Node *p; if (tailNode -- NULL) struct Node * insertSubseq (struct Node *last, int data, int item) puts("Empty"); return; p - tailNode → next; do{ printf("%d ",p→data); p - p > next; while(p !- tailNode →next); void main(void) { struct Node *tailNode - NULL; tailNode -…
Multiple choice in data structures void doo(node<int>*root){ if(root !=0) { node<int>*p=root; while(root->next!=0) root=root->next; p->data=root->data; } What is this code do? a. swap the first item with the last item in the linked list b. set the first item in the linked list as the last item c. doesn't do anything because the root parameter is passed by value d. change the root item in the binary tree with the farthest leaf item

What are the advantages of a linked list versus an array?
linked list is an object that creates, references and manipulates node objects. In this assignment, you are asked to write a Python program to create a linked list and do a set of operations as follows:1. Create an empty linked list2. Create and insert a new node at the front of the linked list3. Insert a new node at the back of the linked list4. Insert a new node at a specified position in the linked list5. Get a copy of the data in the node at the front of the linked list6. Get a copy of the data in the node at a specified position in the linked list7. Remove the node at the front of the linked list8. Remove the node at the back of the linked list9. Remove the node at a specified position in the linked list10.Traverse the list to display all the data in the nodes of the linked list11.Check whether the linked list is empty12.Check whether the linked list is full13.Find a node of the linked list that contains a specified data itemThese operations can be implemented as methods in a…

Question 2: Linked List Implementation You are going to create and implement a new Linked List class. The Java Class name is "StringLinkedList". The Linked List class only stores 'string' data type. You should not change the name of your Java Class. Your program has to implement the following methods for the StringLinked List Class: 1. push(String e) - adds a string to the beginning of the list (discussed in class) 2. printList() prints the linked list starting from the head (discussed in class) 3. deleteAfter(String e) - deletes the string present after the given string input 'e'. 4. updateToLower() - changes the stored string values in the list to lowercase. 5. concatStr(int p1, int p2) - Retrieves the two strings at given node positions p1 and p2. The retrieved strings are joined as a single string. This new string is then pushed to the list using push() method.
