A binary tree is full if all of its vertices have either zero or two children. Let Bn denote the number of full binary trees wit

h n vertices.
(a) By drawing out all full binary trees with 3, 5, or 7 vertices, determine the exact values of B3, B5, and B7. Why have we left out even numbers of vertices, like B4?


(b) For general n, derive a recurrence relation for Bn.

(c) Show by induction that Bn is (2n). 2.14. You are given an array of n elements, and

There are four types of characteristics attributed to a flow: reliability, delay, jitter, and bandwidth. Explain how each of the
sergeinik [125]

Answer and Explanation:

Reliability is important because if the service lacks  lacks reliability this could mean losing a packet or acknowledgement which then requires retransmission.

Delay can be tolerable in different degrees by applications, for example online chatting or conferences need to have the minimum delay possible.

Jitter is the variation in delay for packets belonging to the same flow.

High Jitter: difference between delays is large

Low jitter: difference between delays is small.

Bandwidth depends on the application. In video conferences, for example, there is a need to send million of bits per second to refresh a colour screen while sending a email may not reach even a million.

Lady_Fox [76]

Answer:

<u>Window.java</u>

  1. public class Window {
  2.    int width;
  3.    int height;
  4.    public Window(int width, int height){
  5.        this.width = width;
  6.        this.height = height;
  7.    }
  8.    public int getWidth(){
  9.        return width;
  10.    }
  11.    public int getHeight(){
  12.        return height;
  13.    }
  14.    public int getClientAreaHeight(){
  15.        return getHeight();
  16.    }
  17. }

<u>Main.java</u>

  1. public class Main {
  2.    public static void main (String [] args) {
  3.        Window win1 = new Window(12, 15);
  4.        System.out.println(win1.getClientAreaHeight());
  5.    }
  6. }

Explanation:

<u>Window.java</u>

There is a Window class with two int type attributes, width and height (Line 1 - 3).

The constructor of this class will take two inputs, width and height and set these input to its attributes (Line 5 - 8). There are two methods getWidth and getHeight which will return the value of attributes width and height, respectively (Line 10 - 16).

The required new method getClientAreaHeight is defined in line 18 -20. This method will call the getHeight method to return the height value of the window (Line 19).

<u>Main.java</u>

We test the Window class by creating one Window instance and call the getClientAreaHeight method and print the return output (Line 1 -6).

We shall see 15 is printed.
