What is a computer dedicated to a single function, such as a calculator or computer game? A. TabletB. PDAC.ApplianceD. Minicompu
viktelen [127]

Answer:

C. Appliance.

Explanation:

When a device or machine performs a single function or task, it is commonly referred to as an appliance. Examples of such is an iron, a calculator, a computer game, washing machines, refrigerators, e.t.c

<em>A Personal Digital Assistant (PDA)</em>, is a device, mostly mobile and handheld, that combines various computing features such as telephoning and networking. An example is a tablet. A PDA performs more than a single function.

<em>Minicomputer</em> is a computer usually small in physical size, that is midway in capabilities and support, between a microcomputer and a mainframe computer. An example is also a tablet and our smartphones. Minicomputers are also dedicated to various functions rather than a single function.

In summary, the option that best describes the situation in the question is an appliance.

<em>Hope this helps!</em>

Simora [160]

Answer:

// Scanner class is imported to allow program receive user input

import java.util.Scanner;

// class is defined

public class PlayerRoster {

   // main method that begin program execution

  public static void main(String[] args) {

   // Scanner object scan is defined

     Scanner scan = new Scanner(System.in);

   // multi-dimensional array to hold the jersey number and rating

     int[][] players = new int[5][2];

   // boolean flag to keep program alive

     boolean keepAlive = true;

   // the user input is declared as input of type char

     char input;

     

   // for loop that receive 5 player jersey number and ratings

   // it assigns the received input to the already initialized array

     for (int i = 0; i < 5; i++) {

        System.out.println("Enter player " + (i+1) + "'s jersey number: ");

        players[i][0] = scan.nextInt();

        System.out.println("Enter player " + (i+1) + "'s rating: ");

        players[i][1] = scan.nextInt();

        System.out.println();

     }

   // a blank line is printed

     System.out.println();

   // a method is called to display players array

     outputRoster(players, 0);

     

   // while the flag is true

   // display the Menu by calling the outputMenu method

     while (keepAlive) {

        outputMenu();

       // user input is assigned to input

        input = scan.next().charAt(0);

       //  if user input is 'q' then program will quit

        if (input == 'q') {

           keepAlive = false;

           break;

        }

       //  else if input is o, then outputRoaster is called to display players

        else if (input == 'o') {

           outputRoster(players, 0);

        }

       //  else if input is 'u', then user is allowed to edit a player rating

        else if (input == 'u') {

           System.out.println("Enter a jersey number: ");

           int jerseyNum = scan.nextInt();

           System.out.println("Enter a new rating for the player: ");

           int newRating = scan.nextInt();

           for (int l = 0; l < 5; l++) {

        else if (input == 'a') {

           System.out.println("Enter a rating: ");

           int rating = scan.nextInt();

           outputRoster(players, rating);

        }

        // else if input is 'r', user is allowed to replace a player

        else if (input == 'r') {

           System.out.println("Enter a jersey number: ");

           int jerseyNum = scan.nextInt();

           boolean exists = true;

           for (int l = 0; l < 5; l++) {

              if (players[l][0] == jerseyNum) {

                 System.out.println("Enter a new jersey number: ");

                 players[l][0] = scan.nextInt();

                 System.out.println("Enter a rating for the new player: ");

                 players[l][1] = scan.nextInt();

              }

           }

           

        }

     }

     

     return;

  }

 

// this method take two parameters, players and min

// it then returns player with ratings greater than min

  public static void outputRoster(int[][] players, int min) {

     System.out.println(((min>0) ? ("ABOVE " + min) : ("ROSTER")));

     int item = 1;

     for (int[] player : players) {

        if (player[1] > min) {

           System.out.println("Player " + item + " -- Jersey number: " + player[0] + ", Rating: " + player[1]);

        }

        item++;

     }

     System.out.println();

  }

 

// outputMenu method to display the program menu

  public static void outputMenu() {

     System.out.println("MENU");

     System.out.println("u - Update player rating");

     System.out.println("a - Output players above a rating");

     System.out.println("r - Replace player");

     System.out.println("o - Output roster");

     System.out.println("q - Quit\n");

     System.out.println("Choose an option: ");  

  }

}

You must keep track of some data. Your options are: (1) A linked-list maintained in sorted order. (2) A linked-list of unsorted
ladessa [460]

Answer:

Question was incomplete and continued the question

For each of the following scenarios, which of these choices would be best? Explain your answer.

BST

Sorted Array

Un-sorted Array

a) The records are guaranteed to arrive already sorted from lowest to highest (i.e., whenever a record is inserted, its key value will always be greater than that of the last record inserted). A total of 1000 inserts will be interspersed with 1000 searches.

b) The records arrive with values having a uniform random distribution (so the BST is likely to be well balanced). 1,000,000 insertions are performed, followed by 10 searches.

Explanation:

Answer for a: Un-sorted array or Un-sorted linked list : as mentioned in the question itself that the records are arriving in the sorted order and search will not be O(log n) and insert will be not be O(n).

Answer for b : Un-sorted array or Un-sorted linkedlist : Number of the items to be inserted is already known which is 1,000,000 but it is very high and at the same time search is low. Unsorted array or Unsorted linked list will be best option here.
