A network has N subscribers. Each subscriber is connected directly to all other subscribers.

(ESFs) is accurate: ESFs are not solely a federal coordinating mechanism.

Answer:

1st question:

Utilize k, d, and s as variables to read three distinct inputs: an integer, a float, and a string, respectively. Print these variables in reverse order on one line, ensuring exactly one space separates each. On a second line, print them in their original sequence, with one space in between.

Solution:

In Python:

k = input()  # prompts user to enter k, an integer value

d = input()  # prompts user to provide d, a float value

s = input()  # prompts user to input s, a string

print (s, d, k)  # displays the variable values in reverse order

print (k, d, s)# displays the variable values in the original order

In C++:

#include <iostream>    // for input-output functions

using namespace std;   // to identify objects like cin and cout

int main() {    // start of main function

  int k;   // declare an int variable for the integer value

  float d; //  declare a float variable for the float value

  string s;   //  declare a string variable for string input

  cin >> k >> d >> s;    // reads the values for k, d, and s

  cout << s << " " << d << " " << k << endl;     // displays the variables in reverse order

  cout << k << " " << d << " " << s << endl;   } // displays the variables in their original order

2nd question:

You would want users of your program to enter a customer's last name. Formulate a statement that prompts the user with "Last Name:" and assigns the input to a string variable named last_name.

Solution:

In Python:

last_name = input("Last Name:")

# The input function captures input from the user and assigns it to last_name variable

In C++:

string last_name;  // declare a string variable called last_name

cout<<"Last Name: ";  // prompts user to input last name through this message Last Name:

cin>>last_name; // gathers and assigns the provided value to the last_name variable

The answer is: a. A literal dollar sign, b. Shell variable syntax, and c. End-of-line anchor for pattern matching. Explanation: The $ character within a single-quoted regular expression can represent an end-of-line anchor or act as a literal dollar sign. In a double-quoted context, it assumes shell variable syntax.

The correct option is "video". This is because video formats are more compact compared to text or songs, which are also subjected to lossy compression. The advantages of video encoding are more effective in handling lossy compression, and since text and audio require less information, they compress better. Videos and images necessitate high quality, therefore they are also more suitable for lossy compression.

Explanation:

// Implementation of the TestSolution class

import java.util.Arrays;

public class TestSolution

{

  // Implementing the solution function

  public static int solution(int[] arr)

  {

      // Define local variables

      int i, j, count = 0;

      boolean shines;

     

      // Using nested loops to tally the instances where every lit bulb shines

      for (i = 0; i < arr.length; i++)

      {

          shines = true;

          for (j = i + 1; j < arr.length && shines; j++)

          {

              if (arr[i] > arr[j])

                  shines = false;

          }

          if (shines)

              count++;

      }

      // Return the count of instances where every lit bulb shines

      return count;

      // Output the size and moments of array D
