class Node: def __init__(self, e, n): self.element = e self.next = n
class LinkedList: def __init__(self, a): # Design the constructor based on data type of a. If 'a' is built in python list then # Creates a linked list using the values from the given array. head will refer # to the Node that contains the element from a[0] # Else Sets the value of head. head will refer # to the given LinkedList
# Hint: Use the type() function to determine the data type of a self.head = None # To Do # Count the number of nodes in the list def countNode(self): # To Do # Print elements in the list def printList(self): # To Do
# returns the reference of the Node at the given index. For invalid index return None. def nodeAt(self, idx): # To Do
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.

C++ Programming Language ::::::: Redo the same functions this time as nonmember functions please :
NOTE: You can add only one function into the linked list class get_at_position which will return value of element at given position.
1) Insert before tail : Insert a value into a simply linked list, such that it's location will be before tail.
So if a list contains {1, 2, 3}, insert before tail value 9 is called, the list will become {1, 2, 9, 3}.
2) Insert before value : Insert a value into a simply linked list, such that it's location will be before a particular value.
So if a list contains {1, 2, 3}, insert before 2 value 9 is called, the list will become {1, 9, 2, 3}.
3)Count common elements : Count common values between two simply linked lists.So if a list1 contains {1, 2, 3, 4, 5}, and list2 contains {1, 3, 4, 6}, number of common elements is 3.
4) Check if sorted : Check if elements of simply linked lists are sorted in ascending order or not.So if a list contains {1, 3, 7, 8, 9}…

For example, if a list named 1 contains the values [3, 7, 3, -1, 2, 3, 7, 2, 15, 15], the call of numUniqueValues (1) should return 5. If passed the empty list, you should return 0.

According to the terminology introduced in class, the head reference variable in a singly linked list object references the list's first node. According to the terminology introduced in class, in a doubly linked list, each node references both the head and tail node. In a double-ended singly linked list, the tail reference variable provides access to the entire list. In a circular linked list, the last node references the first node.arrow_forward
- card_t * moveCardBack (card t *head); The moveCardBack function will take the card in front of the pile and place it in the back. In coding terms, you are taking the head of the linked list and moving it to the end. The function has one parameter which is the head of the linked list. After moving the card to the back, the function returns the new head of the linked list.arrow_forwardYou have a sorted linked list. Fill in the missing code in the following function.

- C# Assume you have a LinkedList of Node objects. Both classes have all the normal operations shown below. Your job is to program the DeleteTail method of the LinkedList class. This method locates and deletes the last element of the linked list. You may not change its signature line. Keep your code clean, but no documentation is necessary.
