Smart Pointer: Write a smart pointer class. A smart pointer is a data type, usually implemented with templates, that simulates a pointer while also providing automatic garbage collection. It automatically counts the number of references to a SmartPointer<?> object and frees the object of type T when the reference count hits zero.

PLEASE CODE IN PYTHON  PLEASE USE NESTED CLASS FUNCTION   Design a Point Class with attributes X and Y coordinates. The Class should have following functions: a) change the coordinates, b) return a 2 element list [x,y] c) print a Point object. d) return distance from this instance to a given [x,y]   Also design a Line Class which has 2 Point attributes. The Line class should have functions for following behaviours: a) Return the length of the line. b) Print the equation of the line c) Find if this instance is equal in length to another line.

Java - Gift Exchange   *** Please include UML Diagram and notes in code Minimum requirements are: At least 1 loop An Array or ArrayList At least 3 Java classes  Use methods I am trying to make it so that the program will: Prompt for the number of people included in exchange - If not even it will state that there has to be an even number and ask for the number of people included again (loops). Prompt to enter a participant's first name Prompt for the participant's age Print out the random matching of participants so that everyone gets a gift and everyone gives a gift.  Please include UML Diagram

Course: Data Structure and Algorithims Language: Java Kindly make the program in 2 hours. Task is well explained.  You have to make the proogram properly in Java: Restriction: Prototype cannot be change you have to make program by using given prototype. TAsk: Create a class Node having two data members int data;     Node next;   Write the parametrized constructor of the class Node which contain one parameter int value assign this value to data and assign next to null Create class LinkList having one data members of type Node. Node head Write the following function in the LinkList class publicvoidinsertAtLast(int data);//this function add node at the end of the list publicvoid insertAthead(int data);//this function add node at the head of the list publicvoid deleteNode(int key);//this function find a node containing "key" and delete it publicvoid printLinkList();//this function print all the values in the Linklist public LinkListmergeList(LinkList l1,LinkList l2);// this function…
