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.   Sample Input1:          Sample Output1: 45 23 44 12 37 98 33 35 -1 3   Sample Input2:          Sample Output2: 11 33 44 21 22 99 123 122 124 77 -1 4
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}…
