Remove Duplicates
This function will receive a list of elements with duplicate elements, this function should remove the duplicate elements in the list and return a list without duplicate elements. The elements in the returned list must be in the same order that they were found in the list the function received. A duplicate element is an element found more than one time in the specified list.
5. 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.
struct Node {
int data;
Node * next;
};
Node • head;
a. Write a function named addNode that takes in a variable of type int and inserts it at the head of
the list.
b. Write a function named removeNode that removes a node at the head of the list.

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}…arrow_forward1 Singly Linked List A linked list is a data structure where elements are connected to form a chain where each node points to the next one in the order. Exercise: Given the code of the Node struct, implement a singly linked list with the following functionalities: • addFront: add an integer key to the front of the list. • remove: deletes the smallest number larger than or equal the passed integer and returns the deleted value. If no number is found, returns -1. All cases must be handled. You can define any helper method as needed. #include #include #define INF INT_MAX // indicates infinity value using namespace std; struct Node int key; Node next; Node(int key) { this->key - key; this->next- NULL; }; class SinglyLinkedList public: SinglyLinkedList () head - NULL; void addFront (Node* node) 1 int remove(int val) { private: Node head; }; int main() { SinglyLinkedList sLL - neu SinglyLinkedList (); Node* nodel = new Node (5); Node node2 - neu Node (13); Node node3 - nev Node(7);…arrow_forward
- An iterable is an object that is similar to a list and is created by the range function True or Falsearrow_forwardReference-based Linked Lists: Select all of the following statements that are true. As a singly linked list's node references both its predecessor and its successor, it is easily possible to traverse such a list in both directions. 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_forwardCount dominators def count_dominators(items): An element of items is said to be a dominator if every element to its right (not just the one element that is immediately to its right) is strictly smaller than it. By this definition, the last item of the list is automatically a dominator. This function should count how many elements in items are dominators, and return that count. For example, dominators of [42, 7, 12, 9, 13, 5] would be the elements 42, 13 and 5. Before starting to write code for this function, you should consult the parable of "Shlemiel the painter" and think how this seemingly silly tale from a simpler time relates to today's computational problems performed on lists, strings and other sequences. This problem will be the first of many that you will encounter during and after this course to illustrate the important principle of using only one loop to achieve in a tiny fraction of time the same end result that Shlemiel achieves with two nested loops.
