- Given the interface of the Linked-List struct Node{ int data; Node* next = nullptr; }; class LinkedList{ private: Node* head; Node* tail; public: display_at(int pos) const; ... }; Write a definition for a method display_at. The method takes as a parameter integer that indicates the node's position which data you need to display.

- Tour.java Create a Tour data type that represents the sequence of points visited in a TSP tour. Represent the tour as a circular linked list of nodes, one for each point in the tour. Each Node contains two references: one to the associated Point and the other to the next Node in the tour. Each constructor must take constant time. All instance methods must take time linear (or better) in the number of points currently in the tour. To represent a node, within Tour.java, define a nested class Node: private class Node { private Point p; private Node next; } Your Tour data type must implement the following API. You must not add public methods to the API; however, you may add private instance variables or methods (which are only accessible in the class in which they are declared). public class Tour // Creates an empty tour. public Tour() // Creates the 4-point tour a→b→c→d→a (for debugging). public Tour(Point a, Point b, Point c, Point d) // Returns the number of points in this tour. public…Course: Data Structure and Algorithms Language: C++ Question is well explained Question #2Implement a class for Circular Doubly Linked List (with a dummy header node) which stores integers in unsorted order.

Assume that you don't know if the list has any elements in it or not (i.e., it may be empty). Do not write a complete method, but just show a necessary fragment of code.
