How was the first computer reprogrammed
Answer:
the first programs were meticulously written in raw machine code, and everything was built up from there. The idea is called bootstrapping. ... Eventually, someone wrote the first simple assembler in machine code.
Explanation:
When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This adjustment can be done by normalizing to values between 0 and 1, or throwing away outliers.
For this program, adjust the values by dividing all values by the largest value. The input begins with an integer indicating the number of floating-point values that follow.
Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print('{:.2f}'.format(your_value))
Ex: If the input is:
5 30.0 50.0 10.0 100.0 65.0
the output is:
0.30 0.50 0.10 1.00 0.65
The 5 indicates that there are five floating-point values in the list, namely 30.0, 50.0, 10.0, 100.0, and 65.0. 100.0 is the largest value in the list, so each value is divided by 100.0.
For coding simplicity, follow every output value by a space, including the last one

A medium-sized highway construction company CST has chosen to constrain its investment in computing resources to laptop and desktop computers and the necessary networking hardware and software to access the Internet efficiently. All of CST's data is to be stored off-site through an Internet-enabled storage provider that is used by many different companies and organizations. The service model employed for the data storage capability of only CST is:
Answer:
The service model employed for the data storage capability of only CST is:
SaaS (Software as a Service).
Explanation:
The three cloud computing categories are Infrastructure as a Service (IaaS), Software as a Service (SaaS), and Platform as a Service (PaaS). The three cloud computing services provide different virtual computing resources. In the case of CST, it utilizes only the data storage software of a provider, who provides the data storage infrastructure, including cloud-based servers, while CST uses its own "laptop and desktop computers and other networking hardware and software to access the Internet efficiently."
An example of a host-based intrusion detection tool is the tripwire program. This is a file integrity checking tool that scans files and directories on the system on a regular basis and notifies the administrator of any changes. It uses a protected database of cryptographic checksums for each file checked and compares this value with that recomputed on each file as it is scanned. It must be configured with a list of files and directories to check and what changes, if any, are permissible to each. It can allow, for example, log files to have new entries appended, but not for existing entries to be changed. What are the advantages and disadvantages of using such a tool? Consider the problem of determining which files should only change rarely, which files may change more often and how, and which change frequently and hence cannot be checked. Hence consider the amount of work in both the configuration of the program and on the system administrator monitoring the responses generated.
Answer:
The main problem with such a tool would be resource usage
Explanation:
The main problem with such a tool would be resource usage. Such a tool would need a large amount of CPU power in order to check all of the files on the system thoroughly and at a fast enough speed to finish the process before the next cycle starts. Such a program would also have to allocate a large amount of hard drive space since it would need to temporarily save the original versions of these files in order to compare the current file to the original version and determine whether it changed or not. Depending the amount of files in the system the work on configuring the program may be very extensive since each individual file needs to be analyzed to determine whether or not they need to be verified by the program or not. Monitoring responses may not be so time consuming since the program should only warn about changes that have occurred which may be only 10% of the files on a daily basis or less.

This lab was designed to teach you more about using Scanner to chop up Strings. Lab Description : Take a group of numbers all on the same line and average the numbers. First, total up all of the numbers. Then, take the total and divide that by the number of numbers. Format the average to three decimal places Sample Data : 9 10 5 20 11 22 33 44 55 66 77 4B 52 29 10D 50 29 D 100 90 95 98 100 97 Files Needed :: Average.java AverageRunner.java Sample Output: 9 10 5 20 average = 11.000 11 22 33 44 55 66 77 average = 44.000 48 52 29 100 50 29 average - 51.333 0 average - 0.000 100 90 95 98 100 97 average - 96.667
Answer:
The program is as follows:
import java.util.*;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String score;
System.out.print("Scores: ");
score = input.nextLine();
String[] scores_string = score.split(" ");
double total = 0;
for(int i = 0; i<scores_string.length;i++){
total+= Double.parseDouble(scores_string[i]); }
double average = total/scores_string.length;
System.out.format("Average: %.3f", average); }
}
Explanation:
This declares score as string
String score;
This prompts the user for scores
System.out.print("Scores: ");
This gets the input from the user
score = input.nextLine();
This splits the scores into an array
String[] scores_string = score.split(" ");
This initializes total to 0
double total = 0;
This iterates through the scores
for(int i = 0; i<scores_string.length;i++){
This calculates the sum by first converting each entry to double
total+= Double.parseDouble(scores_string[i]); }
The average is calculated here
double average = total/scores_string.length;
This prints the average
System.out.format("Average: %.3f", average); }
}

Problem 1:
Create a Class named Array2D with two instance methods:
public double[] rowAvg(int[][] array)
This method will receive a 2D array of integers, and will return a 1D array of doubles containing the average per row of the 2D array argument.
The method will adjust automatically to different sizes of rectangular 2D arrays.
Example: Using the following array for testing:
int [][] testArray =
{
{ 1, 2, 3, 4, 6},
{ 6, 7, 8, 9, 11},
{11, 12, 13, 14, 16}
};
must yield the following results:
Averages per row 1 : 3.20
Averages per row 2 : 8.20
Averages per row 3 : 13.20
While using this other array:
double[][] testArray =
{
{1, 2},
{4, 5},
{7, 8},
{3, 4}
};
must yield the following results:
Averages per row 1 : 1.50
Averages per row 2 : 4.50
Averages per row 3 : 7.50
Averages per row 4 : 3.50
public double[] colAvg(int[][] array)
This method will receive a 2D array of integers, and will return a 1D array of doubles containing the average per column of the 2D array argument.
The method will adjust automatically to different sizes of rectangular 2D arrays.
Example: Using the following array for testing:
int [][] testArray =
{
{ 1, 2, 3, 4, 6},
{ 6, 7, 8, 9, 11},
{11, 12, 13, 14, 16}
};
must yield the following results:
Averages per column 1: 6.00
Averages per column 2: 7.00
Averages per column 3: 8.00
Averages per column 4: 9.00
Averages per column 5: 11.00
While using this other array:
double[][] testArray =
{
{1, 2},
{4, 5},
{7, 8},
{3, 4}
};
must yield the following results:
Averages per column 1: 3.75
Averages per column 2: 4.75
My code is:
public class ArrayDemo2dd
{
public static void main(String[] args)
{
int [][] testArray1 =
{
{1, 2, 3, 4, 6},
{6, 7, 8, 9, 11},
{11, 12, 13, 14, 16}
};
int[][] testArray2 =
{
{1, 2 },
{4, 5},
{7, 8},
{3,4}
};
// The outer loop drives through the array row by row
// testArray1.length has the number of rows or the array
for (int row =0; row < testArray1.length; row++)
{
double sum =0;
// The inner loop uses the same row, then traverses all the columns of that row.
// testArray1[row].length has the number of columns of each row.
for(int col =0 ; col < testArray1[row].length; col++)
{
// An accumulator adds all the elements of each row
sum = sum + testArray1[row][col];
}
//The average per row is calculated dividing the total by the number of columns
System.out.println(sum/testArray1[row].length);
}
} // end of main()
}// end of class
However, it says there's an error... I'm not sure how to exactly do this type of code... So from my understanding do we convert it?
Answer:
Explanation:
The following code is written in Java and creates the two methods as requested each returning the desired double[] array with the averages. Both have been tested as seen in the example below and output the correct output as per the example in the question. they simply need to be added to whatever code you want.
public static double[] rowAvg(int[][] array) {
double result[] = new double[array.length];
for (int x = 0; x < array.length; x++) {
double average = 0;
for (int y = 0; y < array[x].length; y++) {
average += array[x][y];
}
average = average / array[x].length;
result[x] = average;
}
return result;
}
public static double[] colAvg(int[][] array) {
double result[] = new double[array[0].length];
for (int x = 0; x < array[x].length; x++) {
double average = 0;
for (int y = 0; y < array.length; y++) {
average += array[y][x];
}
average = average / array.length;
result[x] = average;
}
return result;

Answer:
Design patterns help you write code faster by providing a clear idea of how to implement the design
Explanation:
Design patterns help you write code faster by providing a clear idea of how to implement the design. These are basically patterns that have already be implemented by millions of dev teams all over the world and have been tested as efficient solutions to problems that tend to appear often. Using these allows you to simply focus on writing the code instead of having to spend time thinking about the problem and develop a solution. Instead, you simply follow the already developed design pattern and write the code to solve that problem that the design solves.
