Answer:

The longest codeword that could possibly be for "n" symbol is n-1 bits.

Explanation:

From the given information:

Suppose we are to consider a set of frequencies $\mathtt{f_1,f_2,f_3 ...,f_n}$ , for which f is a symbol for the length n. Therefore, the longest codeword that could possibly be for "n" symbol is n-1 bits.

However, during the encoding for "n" in conjunction with n-2, then the possibilities for n are; $\mathtt{\dfrac{1}{2}, \dfrac{1}{4}, ... \dfrac{1}{2^{n-2}}}$

We can conclude that the longest codeword that could possibly be for "n" symbol is n-1 bits.

Answer:

import java.util.*;

public class Main

{

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

System.out.print("Enter the first: ");

int first = input.nextInt();

System.out.print("Enter the second: ");

int second = input.nextInt();

input.nextLine();

System.out.print("Enter your name: ");

String name = input.nextLine();

int difference = Math.abs(second - first);

System.out.println(name + ", the difference is " + difference);

}

Explanation:

*The code is in Java.

Create a Scanner object to get input from the user

Ask the user to enter the first, second, and name

Calculate the difference, subtract the second from the first and then get the absolute value of the result by using Math.abs() method

Print the name and the difference as in required format

What sequence would a user need to follow to change Chart A into Chart B?

alexandr402 [8]

Either options C or D

You can change the chart type of the whole chart or for single data series in most 2-D charts to give the chart a different look. In 3D or bubble charts, you can only change the chart type of the whole chart. By following the steps in the answers above, you will be in a position to select available chart type like column chart or line chart.

What is the first and last value of i to be displayed by the following code snippet? int n = 20; for (int i = 0; i <= n; i++)

frutty [35]

Answer:

The first value of i is 0 and last value of i is 20.

Explanation:

The following are the description of a given loop.

In this problem, there are two loops one is the internal loop and the other is the external loop

In the outer loop, the value of " i" is initialized with "0" So the first value is printed 0 in the console.

For one value of "i" all the inner loop is executed.

The loop is executed is less equal to 20 that's why the last value of "i" is printed 20 in the console window.
