(Count the occurrences of words in a text file) Rewrite Listing 21.9 to read the text from a text file. The text file is passed as a command-line argument. Words are delimited by whitespace characters, punctuation marks (, ; . : ?), quotation marks (' "), and parentheses. Count the words in a case-sensitive fashion (e.g., consider Good and good to be the same word). The words must start with a letter. Display the output of words in alphabetical order, with each word preceded by the number of times it occurs.
I ran my version of the program solution on its own Java source file to produce the following sample output:

Explanation:

Answer:

Answer:

Explanation:

In programming an array is simply a grouping of various pieces of data. Various data elements are grouped together into a single set and saved into a variable. This variable can be called which would return the entire set which includes all of the elements. The variable can also be used to access individual elements within the set. In Java an example would be the following...

int[] myArray = {33, 64, 73, 11, 13};

In Java, int[] indicates that the variable will hold an array of integers. myArray is the name of the variable which can be called to access the array elements. The elements themselves (various pieces of data) are located within the brackets {}

Answer:

All flags are On ( c, z , N  )

Explanation:

Given data:

4-bit operation

Assuming 2's complement representation

Determine status flags that are on after performing 1010+0110

    1   1

    1  0   1  0

    0  1   1  0

  1  0 0 0 0

we will carry bit = 1 over

hence C = 1

given that: carry in = carry out there will be zero ( 0 ) overflow

hence V = 0

also Z = 1      

But the most significant bit is  N = 1

Explanation:

The code provided worked for the most part, it had some gramatical errors in when printing out the information as well as repeated values. I fixed and reorganized the printed information so that it is well formatted. The only thing that was missing from the code was the input validation to make sure that no negative values were passed. I added this within the getMonths() method so that it repeats the question until the user inputs a valid value. The program was tested and the output can be seen in the attached image below.

Explanation:

Implicit unwrapped optional variables are those which are at option and they might be nil. It is not necessary that all implicit unwrapped optional variables should have an exclamation mark. Swift may eliminate the need for unwrapping.

Answer:

This can be done by a greedy solution. The algorithm does the following:  

Put song 1 on CD1.

For song 1, if there's space left on the present CD, then put the song on the present CD. If not, use a replacement CD.

If there are not any CDs left, output "no solution".

Explanation:  

The main thing is prove the correctness, do that by the "greedy stays ahead argument". For the primary song, the greedy solution is perfect trivially.  

Now, let the optimal solution match the greedy solution upto song i. Then, if the present CD has space and optimal solution puts song (i+1) on an equivalent CD, then the greedy and optimal match, hence greedy is not any worse than the optimal.Else, optimal puts song (i + 1) on subsequent CD. Consider an answer during which only song (i + 1) is moved to the present CD and zip else is modified. Clearly this is often another valid solution and no worse than the optimal, hence greedy is not any worse than the optimal solution during this case either. This proves the correctness of the algorithm. As for every song, there are constantly many operations to try to do, the complexity is O(n).

Explanation:

The following code is written in Python. It is a function that takes two string parameters and compares the lengths of both strings. If the string in variable s1 is greater then the function returns True, otherwise the function returns False. A test case has been provided and the output can be seen in the attached image below.

def compareStrings(s1, s2):

   if len(s1) > len(s2):

       return True

   else:

       return False

print(compareStrings("Brainly", "Competition"))

Answer:

Following are the solution to the given question:

import java.util.Scanner;//import package

public class AscendingAndDescending//defining a class AscendingAndDescending  

{

   public static void main(String[] args) //main method

   {

       int n1,n2,n3,min,max,m;

       Scanner in = new Scanner(System.in);//creating Scanner class object

       System.out.print("Enter an integer: ");//print message

       n1 = in.nextInt();//input value

       System.out.print("And another: ");//print message

       n2 = in.nextInt();//input value

       System.out.print("And just one more: ");//print message

       n3 = in.nextInt();//input value

       min = n1; //use min variable that holds value

       max = n1; //use mix variable that holds value

       if (n2 > max) max = n2;//use if to compare value and hols value in max variable

       if (n3 > max) max = n3;//use if to compare value and hols value in max variable

       if (n2 < min) min = n2;//use if to compare value and hols value in min variable

       if (n3 < min) min = n3;//use if to compare value and hols value in min variable

       m = (n1 + n2 + n3) - (min + max);//defining m variable that arrange value

       System.out.println("Ascending: " + min + " " + m + " " + max);//print Ascending order value

       System.out.println("Descending: " + max + " " + m + " " + min);//print Descending order value

   }

}

Output:

Enter an integer: 8

And another: 9

And just one more: 7

Ascending: 7 8 9

Descending: 9 8 7

Explanation:

In this program inside the main method three integer variable "n1,n2, and n3" is declared that inputs value from the user end and also defines three variable "min, max, and m" that uses the conditional statement that checks inputs value and assigns value according to the ascending and descending order and prints its values.

A class may be a structured diagram that describes the structure of the system.  

It consists of sophistication name, attributes, methods, and responsibilities.  

A mailbox and an email message have certain attributes like, compose, reply, draft, inbox, etc.

Software architecture affects:

Performance, Robustness, Distributability, Maintainability.  

Explanation:

See attachment for the Model object classes which may be utilized in the system implementation to represent a mailbox and an email message.

Advantages:

Large-scale reuse Software architecture is vital because it affects the performance, robustness, distributability, and maintainability of a system.

Individual components implement the functional system requirements, but the dominant influence on the non-functional system characteristics is that the system's architecture.

Three advantages of System architecture:

• Stakeholder communication: The architecture may be a high-level presentation of the system which will be used as attention for discussion by a variety of various stakeholders.

• System analysis: making the system architecture explicit at an early stage within the system development requires some analysis.

• Large-scale reuse:

An architectural model may be a compact, manageable description of how a system is organized and the way the components interoperate.

The system architecture is usually an equivalent for systems with similar requirements then can support large-scale software reuse..

The first is an ascending list of integers, the second is a descending list of integers, and the third is an unordered list of strings. The output can be seen in the attached image below.

import java.util.Scanner;

class Brainly {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Order: " + checkOrder(10, 22, 51, 53));

       System.out.println("Order: " + checkOrder(55, 44, 33, 22));

       System.out.println("Order: " + checkOrder("John", " Gabriel", "Daniela", "Zendaya"));

   }

   public static <E extends Comparable<E>> int checkOrder(E var1, E var2, E var3, E var4) {

       E prevVar = var1;

       if (var2.compareTo(prevVar) > 0) {

           prevVar = var2;

       } else {

           if (var3.compareTo(prevVar) < 0) {

               prevVar = var3;

           } else {

               return 0;

           }

           if (var4.compareTo(prevVar) < 0) {

               return 1;

           }  else {

               return 0;

           }

       }

       if (var3.compareTo(prevVar) > 0) {

           prevVar = var3;

       }

       if (var4.compareTo(prevVar) > 0) {

           return -1;

       }

       return 0;

Answer:

The observed issues in data integration include the following from the listed options:

Two different databases may have different column names for the same actual information (e.g. customer ID vs customer-id).

There may be discrepancies between entries in two different databases for the same actual real-life entity (e.g. for an employee).

Explanation:

Data integration aims at consolidating data from disparate sources into a single dataset provide users with consistent access to data that will meet their various needs.  However, the process of data integration faces many challenges.  One of the challenges is disparate data formats and sources.  There is also the velocity or speed at which data are gathered.  For successful data integration, the different datasets need to be cleaned and updated with quality data.

Answer:

Following are the code to the given question:

import java.util.concurrent.*; //import package

public class Threads //defining a class Threads

{

private Integer s = new Integer(0);//defining Integer class object

public synchronized static void main(String[] args)//defining main method  

{

Threads t = new Threads();//defining threads class object

System.out.println("What is sum ?" + t.s);//print value with message

}

Threads()//defining default constructor

{

ExecutorService exe = Executors.newFixedThreadPool(1000);//defining ExecutorService class object

System.out.println("With SYNCHRONIZATION........");//print message

for(int i = 1; i <= 1000; i++)//defining a for loop

{

exe.execute(new SumTask2());//calling execute method

System.out.println("At Thread " + i +" Sum= " + s + " , ");//print message with value

}

exe.shutdown();//calling shutdown method

while(!exe.isTerminated())//defining while loop that calls isTerminated method

{

}

}

class SumTask2 implements Runnable//calling SumTask2 that inherits Runnable class

{

public synchronized void run()//defining method run

{

int value = s.intValue() + 1;//defining variable value that calls intvalue which is increment by 1

s = new Integer(value);//use s to hold value

}

}

}

Output:

Please find the attached file.

Explanation:

In this code, a Threads class is defined in which an integer class object and the main method is declared that creates the Threads class object and calls its values.

Outside the method, the default constructor is declared that creates the "ExecutorService" and prints its message, and use a for loop that calls execute method which prints its value with the message.

In the class, a while loop is declared that calls "isTerminated" method, and outside the class "SumTask2" that inherits Runnable class and defined the run method and define a variable "value" that calls "intvalue" method which is increment by 1 and define s variable that holds method value.

Checking the age of that the user has passed as an input and changing the variables as needed depending on the age. The background color that was changed was for the form field as the question was not very specific on which field needed to be changed. The piece of the code that was created can be seen in the attached image below.

var validColor = "LightGreen";

var invalidColor = "Orange";

var userAgeInput = document.getElementById("userAge");

var formWidget = document.getElementById("userForm");

var userAgeValid = false;

function userAgeCheck(event) {

   if ((userAgeInput >= 25) && (userAgeInput <= 35)) {

       document.getElementById("userForm").style.backgroundColor = validColor;

       userAgeValid = true;

   } else {

       document.getElementById("userForm").style.backgroundColor = invalidColor;

       userAgeValid = false;

   }

};

Answer:

Hence the answer is top and peek.

Explanation:

In a stack, we insert and delete an item from the top of the stack. So we use variables top, peek to stay track of the position.

The insertion operation is understood as push and deletion operation is understood as entering stack.

Hence the answer is top and peek.

Answer:

The program is as follows:

[tex]mult\_table = [[1, 2, 3], [2, 4, 6], [3, 6, 9]][/tex]

count = 1

for row in mult_table:

   for item in row:

       if count < len(row):

           count+=1

           print(item,end="|")

       else:

           print(item)

   count = 1

Explanation:

This initializes the 2D list

[tex]mult\_table = [[1, 2, 3], [2, 4, 6], [3, 6, 9]][/tex]

This initializes the count of print-outs to 1

count = 1

This iterates through each rows

for row in mult_table:

This iterates through each element of the rows

   for item in row:

If the number of print-outs is less than the number of rows

       if count < len(row):

This prints the row element followed by |; then count is incremented by 1

           count+=1

           print(item,end="|")

If otherwise

       else:

This prints the row element only

           print(item)

This resets count to 1, after printing each row

   count = 1

To delete the whitespace, you have to print each element as:            print(item,end="|")

See that there is no space after "/"

Answer:

count = 1

for row in mult_table:

  for item in row:

      if count < len(row):

          count+=1

Answer:

The program in Java is as follows:

import java.util.*;

public class Main {

public static void removeDuplicate(ArrayList<Integer> list){

 ArrayList<Integer> newList = new ArrayList<Integer>();

 for (int num : list) {

  if (!newList.contains(num)) {

   newList.add(num);  }  }

 for (int num : newList) {

     System.out.print(num+" ");  } }

public static void main(String args[]){

 Scanner input = new Scanner(System.in);

 ArrayList<Integer> list = new ArrayList<Integer>();

 System.out.print("Enter ten integers: ");

 for(int i = 0; i<10;i++){

     list.add(input.nextInt());  }

 System.out.print("The distinct integers are: ");

 removeDuplicate(list);

}}

Explanation:

This defines the removeDuplicate function

public static void removeDuplicate(ArrayList<Integer> list){

This creates a new array list

 ArrayList<Integer> newList = new ArrayList<Integer>();

This iterates through the original list

 for (int num : list) {

This checks if the new list contains an item of the original list

  if (!newList.contains(num)) {

If no, the item is added to the new list

   newList.add(num);  }  }

This iterates through the new list

 for (int num : newList) {

This prints every element of the new list (At this point, the duplicates have been removed)

     System.out.print(num+" ");  } }

The main (i.e. test case begins here)

public static void main(String args[]){

 Scanner input = new Scanner(System.in);

This declares the array list

 ArrayList<Integer> list = new ArrayList<Integer>();

This prompts the user for ten integers

 System.out.print("Enter ten integers: ");

The following loop gets input for the array list

 for(int i = 0; i<10;i++){

     list.add(input.nextInt());  }

This prints the output header

 System.out.print("The distinct integers are: ");

This calls the function to remove the duplicates

 removeDuplicate(list);

}}
