7) Consider a Linked List class called LL, that has a Node pointer (Node*) called head. A Node is a struct composed of an integer element called value and a Node pointer to the next Node called next. The last Node's next is nullptr. Fill in functions A and B below. Note: You do NOT need to implement other functions of LL. struct Node { int value; Node* next; } class LL { private: Node* head; public: void insertAtFront(int num); void deleteRear(int num); }; // Function A: insert a node with value num at the front of the list. void LL:insertAtFront(int num) { //provide your code here } /* Function B: delete the last node in the list. If the list is empty when this is called, print an error message (çcout) stating so instead of deleting anything. Your function must not cause a memory leak! */ void LL::deleteRear(int num) // insert a node with value num at the front of the list. { //provide your code here

In java The following is a class definition of a linked list Node:class Node{int info;Node next;}Assume that head references a linked list and stores in order, the int values 5, 7 and 9.  Show the instructions needed to delete the Node with 5 so that head would reference the list 7 and 9.

1)Write a Java program which stores three values by using singly linked list.- Node class1. stuID, stuName, stuScore, //data fields2. constructor3. update and accessor methods- Singly linked list class which must has following methods:1. head, tail, size// data fields2. constructor3. update and accessor methodsa. getSize() //Returns the number of elements in the list.b. isEmpty( ) //Returns true if the list is empty, and false otherwise.c. getFirstStuID( ), getStuName( ), getFirstStuScore( )d. addFirst(stuID, stuName, stuScore)e. addLast(stuID, stuName, stuScore)f. removeFirst ( ) //Removes and returns the first element of the list.g. displayList( ) //Displays all elements of the list by traversing the linked list.- Test class – initialize a singly linked list instance. Test all methods of singly linked list class.       2. Write a Java program which stores three values by using doubly linked list.- Node class4. stuID, stuName, stuScore, //data fields5. constructor6. update and…

Write C code that implements a soccer team as a linked list. 1. Each node in the linkedlist should be a member of the team and should contain the following information: What position they play whether they are the captain or not Their pay 2. Write a function that adds a new members  to this linkedlist at the end of the list.
