A linked stack is implemented using a standard Node class as follows: import java.util.*; class stack implements Iterable {private Node top; private int size; public stack () {top = null; size = 0;} public Object pop() {if (size == 0) throw new RuntimeException (\"\"); Object answer = top.getData (); top = top.getNext (); Size --; return answer;} public void push (Object x) {Node newNode = new Node (x top); top = newNode; size++;}//the iterator method is missing} Write a class StackIterator to implement objects that can be returned by the stack iterator. Also write the missing stack method called iterator. You can decide whether the iterator will run through the data in the stack in LIFO or FIFO order (one choice is much easier). Solution Hi, Pease find the program below: import java.util.*; import java.lang.Iterable; @SuppressWarnings(\"rawtypes\") public class LinkedStack implements Iterable{ private int n; // size of the stack private Node first; // top of stack // Helper linked list class private class Node { private Object item; private Node next; } /** * Initializes an empty stack. */ public LinkedStack() { first = null; n = 0; } /** * Is this stack empty? * @return true if this stack is empty; false otherwise */ public boolean isEmpty() { return first == null; } /** * Returns the number of items in the stack. */ public int size() { return n; } /** * Adds the item to this stack. */ public void push(Object item) { Node oldfirst = first; first = new Node(); first.item = item; first.next = oldfirst; n++; } /** * Removes and returns the item most recently added to this stack. * @return the item most recently added */ public Object pop() { if (isEmpty()) throw new NoSuchElementException(\"Stack underflow\"); Object item = first.item; // save item to return first = first.next; // delete first node n--; //decreases the size by 1 return item; // return the saved item } /** * Returns (but does not remove) the item most recently added to this stack. * @return the item most recently added to this stack */ public Object peek() { if (isEmpty()) throw new NoSuchElementException(\"Stack underflow\"); return first.item; } /** * Returns an iterator to this stack that iterates through the items in LIFO order. */ public Iterator iterator() { return new ListIterator(); } // an iterator, doesn\'t implement remove() since it\'s optional private class ListIterator implements Iterator { private int i = n; private Node first1 = first; //the first node public boolean hasNext() { return (i > 0); } public Object next() { Object item = first1.item; first1 = first1.next; i--; return item; } public void remove() { // not needed as this is optional } } //Main method to implement the test public static void main(String[] args) { Scanner scan = new Scanner(System.in); /* Creating object of class linkedStack */ LinkedStack ls = new LinkedStack(); /* Perform Stack Operations */ System.out.println(\"Linked Stack Test\ \"); char ch; do { System.out.println(\"\ Linked Stack .

What professions were represented on the team? What role did each member play in achieving the team’s shared goal? To what extent was your teamwork experience successful? Why or why not? (in your own words-not copy and paste) Solution According to Bernard Barett, (2016) the following professions were represented on the team: Psychologist, Counsellors, behavioural teams, nursing, social workers, Psychiatrist, Art therapist, General Practictioners. Each member play a definite role in achieving the shared role. Members share a high degree of coordination and teamwork. When individuals grasp each other well, they\'re rather more possible to figure well along. New member can stay somewhat isolated till everybody else gets to grasp her. If you\'ve got many workers on speaking terms and you throw them along into a project. I work in a healthcare organziation as a nursing staff and my experience of team was successful with lots of new experiences. When health care suppliers work as a team, they will be a lot of awake to changes as they occur, in line with a research team funded by the Canadian Health Services analysis. once a patient’s condition worsens, the team appearance to the leader, knowing that every person on the team will fulfill his various duties and work with others to resolve issues. Nurses, doctors and assistants operating as a team tend to create fewer mistakes, resulting in improved patient outcomes.Team members are more practical health care suppliers once they work along as a result of they have a tendency to be told a lot of concerning what role every member plays. you wish to know the duties of every team member to figure along effectively, increasing your own skills as duties typically overlap. As a part of the team, you come back to know and appreciate the roles of physicians, nurses, nursing assistants, social staff, physical therapists and directors as you communicate and work along within the best interests of the patient..

what is the threat and solution for when alice sends a password and bob hashing it and comparing it against a database of hashed passwords? Solution In given scenario, dictionary attack may be the possible threat in which hacker tries to get the decipher key by trying million of possibilities like in dictionary. There are various data types of dictionary attack software in the market which ease the work of a hacker. Possible solution for the given threat is using salt which is a random data which is used an additional input for the hashing. A new salt is generated for each password. Generated salt and password are concated and applied to hash function and obtained result is stored in the database with salt value. Since, salt is different for each password, therefore it can be used for common passwords as well. For example, salt is used in UNIX system credentials, Internet security etc..

What is the difference between sequential file access and random file access? Describe a unique scenario (different than submitted by classmates) where each type of file access could be used (no coding required). Solution the main differenece is we should have to incremenet the address to the reach the specified loaction in sequenctial access but in random access we will get the address of the loaction and can reach it directly.(it can implemeted using pointers) sequential accesss: in this the data is accessed in a memory devices in sequencial or predefined way or in an ordered sequence example of sequencial access: iam giving you the real world senario as a example: a student named john is living in an hostel he want his friend named rock. in hostel there are 100 rooms sequencially john is in 20th room and rock is in 90 th room .but john doesnt know which room he is so he started searching one by one room sequencially like(21 22 23..90). this is one of the example for sequential access random access: it is one type of process in which specified memory can access by using address of the memory and can be accessed directly . example of random access: now if we use the above example if john known room number of the rock then he need not to search all the room he just directly reach the 90 th where rock is situated..

This class will implement a hash table. The hash table will hold data items whose type is tuple. This class will have following public methods and constructor. HashTable(int size) Finds the smallest prime integer p whose value is at least size. Creates a hash table of size p where each cell initially is NULL. It will determine the hash function to be used in the hash table by creating the object new HashFunction(p). maxLoad () Returns the maximum load of the hash table averageLoad () Returns the average load of the hash table size () returns the current size of the hash table. numElements() returns the number of Tuples that are currently stored in the hash table. loadFactor() return the load factor which is numElements()/size() add (Tuple t) Adds the tuple t to the hash table; places t in the list pointed by the cell h(t.getKey()) where h is the hash function that is being used. When the load factors become bigger than 0.7, then it (approximately) doubles the size of the hash table and rehashes all the elements (tuples) to the new hash table. The size of the new hash table must be: Smallest prime integer whose value is at least twice the current size. search (int k) returns an array list of Tuples (in the hash table) whose key equals k. If no such Tuples exist, returns an empty list. Note that the type of this method must be ArrayList remove (Tuple t) Removes the Tuple t from the hash table. Solution HashTable.java import java.math.BigInteger; import java.util.ArrayList; public class HashTable { TupleCell[] hashTable; //Table to store Tuple cells HashFunction hashFunction; //Current hash Function public HashTable(int size) { int actualSize = Math.abs(size); while (!new BigInteger(Integer.toString(actualSize)).isProbablePrime(1)) actualSize++; //Determining next prime number hashTable = new TupleCell[actualSize]; //Create tuple cells hashFunction = new HashFunction(actualSize); //Create hash function } public int maxLoad() { //Maximum load in hash table int maxValue = 0; for (TupleCell tupleCell : hashTable) { TupleCell node = tupleCell; int count = 0; while (node != null) { count++; node = node.nextCell; } if (count > maxValue) { maxValue = count; } } return maxValue; } public double averageLoad() { //avarage load in hash table return ((double) numElements()) / size(); } public int size() { //size of table return hashTable.length; } public int numElements() { // number of elements in table int count = 0; for (TupleCell tupleCell : hashTable) { TupleCell node = tupleCell; while (node != null) { count++; node = node.nextCell; } } return count; } public double loadFactor() { //load factor return ((double) numElements()) / size(); } public void add(Tuple t) { TupleCell node = hashTable[hashFunction.hashIndex(t.getKey())]; if (node == null) { hashTable[hashFunction.hashIndex(t.getKey())] = new TupleCell(t); //If hash table cell is empty } else { while (node.nextCell != null) { node = node.nextCell; } node.nextCell = new TupleCell(t); //adding new .

Therefore, for each development of new technologies, a business may have to totally change their operating process. The change of technology will affect the way a company carries out business. Through the ages the travel and tourism industry has developed significantly with the development of new technology. On a global scale new technology has changed the way of tourism. In the dark ages travel on land was in litters or chariots and small boats was used to travel on sea. Tourism and pleasure travel was in existence but otr active during this time, but by the middle of the Middle Ages, large numbers took on a new life with the main purpose of traveling to Europe for religious purposes. Travel in the 18th century was by high society people mainly to visit spas a major attraction which also provided social events, games, dancing, gambling and sea-bathing. With the development of railway in the late 1830\'s, direct contribution of major seaside resorts was established and gave everyone an opportunity to travel as demand for vacation travel grew. The first publicly advertised excursion train developed by Thomas Cook, who was then looked upon as the first travel agent and now owns one of the largest travel agency in the world.As the improvement on technology increased modern internet allowed tourist quick and easy access to information such as travel destinations, lodging and dining options at the destination, up to the minute wait time and making reservations before departing for their chosen destination. The use of telephones also allowed travelers quick contact without ever experiencing a busy signal or getting out pf bed. It also allowed for the collection of payment from prospective travelers before departing for the destination. According to \" the journal of information technology and tourism\", modern communication technology likewise 21st century developments in mobile telephone technology allows for advertising of attractions at various tourist destinations to target visitors..

The Miami Beach police department is sick and tired of the college and high school students coming to town for Spring break and bringing drugs and alcohol with them. So, they’ve devised a plan, Operation Intercept, to stop the flow of drugs. First, the Police Chief orders random check points on all the highways leading into town. Each check point will have a drug dog that will go around the outside of the vehicle and alert the handler if there is a “hit.” Second, to help stop the flow of drugs entering the city via the waterways and ports, the Chief has ordered the use of drones. He instructs his officers to conduct drone “flights” in the areas where the drug dealers often use speedboats for drug trafficking. As expected, Operation Intercept is successful. The Department makes a number of arrests based upon both the traffic stops and the drones. Discuss whether drug dogs at the traffic stops and the drones are constitutional under the 4th Amendment. Solution Answer:- Fourth Amendment understanding (taken from book):- The United State Constirution, in Fourth Amendment, is part of Bill of Rights, protects people or prohibits from unreasonable searches and seizer by government and it requires any search warrant to be judicially sanctioned and supported by probable cause. But it doesn’t give guarantee against searches and seizer but only those that are deemed unreasonable under the law. Case Evaluation:- Operation Intercept carried by The Miami Police Department is to stop the flow of drugs to city during Spring. This is of good intent that will not only help to control drug flow but will help to keep control on unwanted environment in city and will maintain harmony and peace in city while people enjoying their summer alongwith city continue to reap benefits from tourism activities. Dogs sniffing at patrolling point is correct as per 4th Amendment as it is only taking not more than two minutes of tourist time but helping to keep control on unreasonable drug flow in the city. Moreover, patrolling is like paying toll money that helps government to pass on benefits to people in way of providing better infrastructure (and here by patrolling returns are in form of peace and harmony during their summer vacation tour). Drones flying only captures images of external environment and it is not interfering on people privacy hence it is correct as per 4th Amendment as it is not searching on people.The images are helping police department to check speed of boat that could bring unlawful flow of drugs..

This definition structurally resembles that of Avedon and Sutton-Smith, but contains concepts from many of the other authors as well. References: Salen, K., & Zimmerman, E. (2004). Rules of play: Game design fundamentals. Cambridge, Massachusetts: The MIT Press. Salen and Zimmerman (2004) reviewed many of the major writers on games and simulations and synthesized the following definitions: \"A game is a system in which players engage in an artificial conflict, defined by rules, that results in a quantifiable outcome\" (p. 80). They contended that some simulations are not games but that most games are some form of simulation. References: Salen, K., & Zimmerman, E. (2004). Rules of play: Game design fundamentals.
