Complete this method in class List that returns a reference to the node containing the data item in the argument findThis, Assume that findThis is in the list public class list { protected Node head ; Protected int size ; Public Node find (char find this) { Node curr = head; while(curr != null) { if(curr.info == findThis) return curr; curr = curr.link; } return -1; } }struct nodeType { int infoData; nodeType * next; }; nodeType *first; … and containing the values(see image) Using a loop to reach the end of the list, write a code segment that deletes all the nodes in the list. Ensure the code performs all memory ‘cleanup’ functions.Grocery shopping list (linked list: inserting at the end of a list) Given main() in the ShoppingList class, define an insertAtEnd() method in the ItemNode class that adds an element to the end of a linked list. DO NOT print the dummy head node. Ex. if the input is: 4 Kale Lettuce Carrots Peanuts where 4 is the number of items to be inserted; Kale, Lettuce, Carrots, Peanuts are the names of the items to be added at the end of the list. The output is: Kale Lettuce Carrots Peanuts

Show PolynomialADT interface 2. Create the PolyNodeClass with the following methods: default constructor, overloaded constructor, copy constructor, setCoefficient, setExponent, setNext, getCoefficient, get Exponent, getNext 3. Create the PolynomialDataStrucClass with the following methods: default constructor, overloaded constructor, copy constructor, isEmpty, setFirstNode, getFirstNode, addPolyNodeFirst (PolyNode is created and set to beginning of polynomial), addPolyNodeLast, addPolyNode (PolyNode is set to the end of polynomial), addPolynomials, toString 4.

List Member Deletion Modify the list class you created in the previous programming challenges by adding a function to remove an item from the ist and by adding a destructor: void zemove (double x) : Linkedtist (02 Test the class by adding a sequence of instructions that mixes operations for adding items, removing items, and printing the list.
- 6. Suppose that we have defined a singly linked list class that contains a list of unique integers in ascending order. Create a method that merges the integers into a new list. Note the additional requirements listed below. Notes: ● . Neither this list nor other list should change. The input lists will contain id's in sorted order. However, they may contain duplicate values. For example, other list might contain id's . You should not create duplicate id's in the list. Important: this list may contain duplicate id's, and other list may also contain duplicate id's. You must ensure that the resulting list does not contain duplicates, even if the input lists do contain duplicates.struct node{ int a; struct node * nextptr; }; Write two functions. One for inserting new values to a link list that uses the given node structure. void insert(struct node **head, int value); Second function is called to count the number of even numbers in the link list. It returns an integer that represents the number of even numbers. int countEvenNumbers(struct node *head); Write a C program that reads a number of integers from the user and insert those integers into a link list (use insert function). Later pass the head pointer of this link list to a function called countEvenNumbers. This function counts and returns the number of even numbers in the list. The returned value will be printed on the screen. Note 1: Do not modify the function prototypes.
