Linked list:
Linked list is a linear and dynamic data structure which is used to organize data; it contains sequence of elements which are connected together in memory to form a chain. The every element of linked list is called as a node.

C++
The List class represents a linked list of dynamically allocated elements. The list has only one member variable head which is a pointer that leads to the first element. See the following code for the destructor to List.
~ List () {
for (int i = 0; i <size (); i ++)
{
pop_back ();
}
}
What problems does the destructor have?
Select one or more options:
1. There are no parameters for the destructor.
2. The return value from pop_back (if any) is nerver handled.
3. The destructor will create a stack overflow.
4. The destructor will create dangling pointers.
5.The destructor will create memory leaks.
6.The destructor will create undefined behavior (equivalent to zero pointer exception).
7.The condition must be: i <size () - 1
8. There is at least one problem with the destructor, but none of the above.
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
The definition of linked list is given as follows:
struct Node {
ElementType Element ;
struct Node *Next ;
} ;
typedef struct Node *PtrToNode, *List, *Position;
If L is head pointer of a linked list, then the data type of L should be ??

- linked_list_stack_shopping_list_manager.py This is a file that includes the class of linked list based shopping list manager. This class contains such methods as init, insert_item, is_list_empty, print_item_recursive_from_top, print_items_from_top, print_item_recursive_from_bottom, print_items_from_bottom, getLastItem, removeLastItem. In addition, this class requires the inner class to hold onto data as a linked list based on Stack. DO NOT use standard python library, such as deque from the collections module. Please keep in mind the following notes for each method during implementation: Init(): initializes linked list based on Stack object to be used throughout object life. insert_item(item): inserts item at the front of the linked list based on Stack. Parameters: item name. is_list_empty (): checks if the current Stack object is empty (ex. check if head is None). print_item_recursive_from_top(currentNode): a helper method to print linked list based on Stack item recursively.

Design your own linked list class to hold a series of integers using C++. The class should have member functions for appending, inserting, and deleting nodes. Don't forget to add a destructor that destroys the list. Demonstrate the class with a driver program. 2. Modify the linked list class you created to add a print member function. The function should display all the values in the linked list. Test the class by starting with an empty list, adding some elements, and then printing the resulting list out.arrow_forward
- Topic: Singly Linked ListImplement the following functions in C++ program. Read the question carefully.
