C

A
C

C
A

Answer:

The output is

C

A

Explanation:

Given

The given code segment

Required

The output of test_1()

When test_1() is called from main, the following is executed:

def test_1():

  test_3()  ---- This calls test_3()

  print("A") --- This is then executed after test_3() has been executed

For test_3()

def test_3():

print("C") --- This prints C

Back to test_1()

  print("A") --- This prints A

So, the output is:

C

A

In this exercise we have to use the knowledge of computational language in python to write the code.

We have the code in the attached image.

The code in python can be found as:

def test_1():

 test_3()

 print("A")

def test_3():

print("C")

Back to test_1()

 print("A")

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

You have been tasked with building a URL file validator for a web crawler. A web crawler is an application that fetches a web page, extracts the URLs present in that page, and then recursively fetches new pages using the extracted URLs. The end goal of a web crawler is to collect text data, images, or other resources present in order to validate resource URLs or hyperlinks on a page. URL validators can be useful to validate if the extracted URL is a valid resource to fetch. In this scenario, you will build a URL validator that checks for supported protocols and file types.
What you need to do?
1. Writing detailed comments and docstrings
2. Organizing and structuring code for readability
3. URL = :///
Steps for Completion
Task
Create two lists of strings - one list for Protocol called valid_protocols, and one list for storing File extension called valid_ftleinfo . For this take the protocol list should be restricted to http , https and ftp. The file extension list should be hrl. and docx CSV.
Split an input named url, and then use the first element to see whether the protocol of the URL is in valid_protocols. Similarly, check whether the URL contains a valid file_info.
Task
Write the conditions to return a Boolean value of True if the URL is valid, and False if either the Protocol or the File extension is not valid.
main.py х +
1 def validate_url(url):
2 *****Validates the given url passed as string.

Assume a manufacturing company which manufactures and sells several electronic
products. This company has a list of suppliers who supply various components for
different products. Several components assembled together form a product. A product
will be manufactured in many work centers. Each product contains several components.
A product has at least one component and may comprise of several components. A
component must belong to a product and the same component can be used in multiple
products. Also mention the quantity of the component which a product requires.
Company has a list of suppliers who supply various components. A supplier may not
be supplying any component and may supply several components. A component must
be supplied by at least one supplier or several suppliers may provide the same
component. A supplier supplies the quantity and unit price of the products. A supplier
also supplies the quantity and unit price of the components. Each product will be
manufactured in single or multiple work centers. A work center may not produce a
product and may produce several products. Each work center will have one or more
employees and an employee would be working in single work center only. A customer
may not place any order and may place multiple orders. But an order will belong to a
specific customer only. Each order may contain single product or multiple products and
the same product may be demanded in many orders.
Construct an ER diagram for the manufacturing company.

Question 20:
Which of the following scenarios involve computers making predictions based on the analysis of
patterns in large data sets?
Select two answers.
Astate education board analyzing demographic information and academic records to identify students at risk
of dropping out of school.
The federal government analyzing state spending data to identify which states spent the most on social
services
A video streaming service analyzing viewer's habits to suggest videos based on the viewing history of other
viewers.
An airline analyzing flight records to determine the routes it operates with the least bookings.

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
