The function below tries to create a list of integers by reading them from a file. The file is expected to have a single integer per line and the code works correctly in that case. If any of the lines don't contain just an integer, than this code fails. Fix this code so that it ignores any lines that don't contain integers instead of raising an exception. Do this with try/except blocks. Your code should still return the list of integers from the lines that contain integers.

Answer:

The answer is "loss of 1,260,000"

Explanation:

Following are the important points of the question:

The cost of research and development is = $3840000

net income of the company is=  $2580000

Find: loss or profit .

According to the rate of the cost, the company cost is higher than the company rate. So, the company goes in loss stage, then  

Loss = total cost - net income

Loss = $3840000 - $2580000

Loss= $ 1,260,000

The computer company would face a net loss of $1,260,000.

The question is asking about the calculation of net income or loss for a computer company after accounting for research and development costs. To determine the net income or loss, we subtract the research and development (R&D) costs from the company's income before these costs are accounted for.

So, if the net income before R&D costs is $2,580,000 and the R&D costs are $3,840,000, we perform the following calculation:

Net Income after R&D = Net Income before R&D - R&D costs

Net Income after R&D = $2,580,000 - $3,840,000

Net Income after R&D = -$1,260,000

This result is a net loss of $1,260,000 after accounting for R&D costs.

def print_shampoo_instructions(num_cycles):

   if num_cycles < 1:

       print("Too few.")

   elif num_cycles >4:

       print("Too many.")

   else:

       N = 1

       for N in range (N,num_cycles+1):

           print(N,": Lather and rinse.")

       print("Done.")

Explanation:

Final answer:

The function shampoo_instructions() controls repetitions based on input, preventing infinite loops, akin to the shampoo instructions' issue. It emphasizes the importance of iteration control in programming loops to avoid endless execution. Understanding how to manage loop cycles prevents program malfunction due to infinite loops.

Explanation:

shampoo_instructions() is a function that takes a parameter num_cycles and prints instructions based on the input. If num_cycles is less than 1, it prints 'Too few.'; if more than 4, it prints 'Too many.'; otherwise, it prints the cycle number followed by 'Lather and rinse.' num_cycles times.The directions on shampoo create an infinite loop since they lack an iteration variable to specify the number of repetitions. In programming, developers must include a mechanism to control loops' execution, preventing infinite iterations.

In a loop, each iteration represents a cycle, akin to the instructions in shampoo; therefore, the concept of controlling the number of repetitions is fundamental to avoid infinite loops and ensure proper program execution.

Explanation:

The first 3 lines of code tell the user to input a 5 digit number (ex. 72,910) or a 1 digit number (ex. 3). The next 5 lines of code determine if it is a 5/1 digit number or not. If it is, it prints "Success!". The rest of the code just tells that if it's not a 5/1 digit number, and if it's not, it gives errors and tells the user to try again.

Answer: Wait, you're asking strangers to write a report for you? Just use common sense--tell her to forward the emails to the police department, or to provide the login details or the IPv4 logs (depending on the email service) to work off of. Considering that she most likely has the email linked to her phone, you should get into contact with her phone provider to locate the daughter. I don't know what else to say considering that you're asking strangers for an essay to be written for you. Hopefully what I said helps, but I doubt that anyone's going to write a full two page essay.

APA offers authors a dependable structure they can use each time they write. Authors' arguments or research are more effectively organized when they are consistent.

The APA format helps papers on usually complex issues to be more understandable. It makes reading and understanding papers easier.

Utilize common sense and instruct her to transmit the emails to the police department, or, depending on the email service, to supply the login information or the IPv4 logs for investigators to use.

You should get in touch with her phone provider to find the daughter because she almost certainly has the email connected to her phone.

Therefore, I don't know what else to say, considering that you're asking strangers for an essay to be written for you.

Final answer:

To create a balanced binary search tree from a sorted array, you can use a recursive approach. Here is an example Java code that can be used as a starting point. The code creates a balanced binary search tree by selecting the middle element as the current node and calling the createBalancedBST method on the left and right subarrays.

Explanation:

In order to create a balanced binary search tree from a sorted array, you can use a recursive approach. Here is an example Java code that can be used as a starting point:

import java.util.ArrayList;

class Node<T> {
   Node<T> left;
   Node<T> right;
   T value;

   Node(T value) {
       this.value = value;
       this.left = null;
       this.right = null;
   }
}

public class TreeDriver<T extends Comparable<T>> {
   Node<T> root;

   TreeDriver() {
       this.root = null;
   }
   
   private Node<T> createBalancedBST(T[] arr, int start, int end) {
       if (start > end)
           return null;
       
       int mid = (start + end) / 2;
       Node<T> node = new Node<>(arr[mid]);
       
       node.left = createBalancedBST(arr, start, mid - 1);
       node.right = createBalancedBST(arr, mid + 1, end);
       
       return node;
   }
   
   private void inOrderTraversal(Node<T> node) {
       if (node == null)
           return;
       
       inOrderTraversal(node.left);
       System.out.print(node.value + " ");
       inOrderTraversal(node.right);
   }
   
   public void createAndPrintBalancedBST(T[] arr) {
       this.root = createBalancedBST(arr, 0, arr.length - 1);
       inOrderTraversal(this.root);
   }
   
   public static void main(String[] args) {
       TreeDriver<String> tree = new TreeDriver<>();
       String[] arr = {"A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M","N"};
       tree.createAndPrintBalancedBST(arr);
   }
}

The createBalancedBST method takes an array arr, a start index, and an end index. It recursively creates a balanced binary search tree by selecting the middle element as the current node and calling the createBalancedBST method on the left and right subarrays.

The inOrderTraversal method is used to print the values of the created BST in order.

Options:

a) The client wants to develop internal resources and capabilities

b) The client is looking for the lowest possible costs

c) The client has unique business requirement that must be satisfied by this software application

d) The client has some existing technology in place whose requirements must be met by the new software

Answer:

d) The client has some existing technology in place whose requirements must be met by the new software

Explanation:

For a client to purchase a software, the client has an already existing technology that requires that software for adequate functioning. The analyst will recommend the new software to the client based on the technology he/she previously has and the requirements he wants to meet.

The other options are not impossible, but they are not the primary reason why the software will be purchased, the overall aim for all the company's activities may be to develop internal resources and capabilities or to meet some unique business requirements, but these are secondary. The primary purpose is that the client has a technology that cannot function properly without the recommended software.

Answer:

lst = []

n = int(input("Input an array size for you words array: "))

print("Now please enter " + str(n) + " words")

max = 0

min = 1000

index_min = 0

index_max = 0

for i in range(n):

   s = input("Input a word: ")

   lst.append(s)

   if len(s) >= max:

       max = len(s)

       index_max = i

   if len(s) <= min:

       min = len(s)

       index_min = i

print("The longest word is :" + lst[index_max])

print("The shortest word is :" + lst[index_min])

Explanation:

Create an empty list, lst

Get the size from the user

Create a for loop that iterates "size" times

Inside the loop, get the strings from the user and put them in the lst. Find the longest and shortest strings and their indices using if structure.

When the loop is done, print the longest and shortest

Explanation:

IPSec-based VPN is configured in two different modes namely

IPSec Tunnel mode and IPSec Transport mode so here we are using IPsec transport mode which is used for end to end communications between a client and a server in this original IP header is remain intact except the IP protocol field is changed and the original protocol field value is saved in the IPSec trailer to be restored when the packet is decrypted on the other side due to this arrangement you need to use application based firewall because there are certain specific rules that can address the particular field (explained above-change in IP protocol field) which at the other end need to be same so at the type of decryption, original IP protocol field can be matched.

To ensure that Susan no longer has access without erasing her files I'll take the following steps:

B

The benefits that accrue to retaining her information will depend on the value of information that her account possesses. As the former executive IT personnel, this is most likely the case.

In the long run, the safest thing to do might be to just back up all information she created and had access to to a remote storage or data warehouse.

Cheers!

Answer:

Code segment II produces correct output for all values of str, but code segment I produces correct output only for values of str that contain "pea" but not "pear".

Explanation:

The main issue with the first code segment is the way how the if else if condition are arranged. The "pea" is checked at the earliest time in the first code segment and therefore so long as there is the "pea" exist in the string (regardless there is pear or pearl exist in the string as well), the if condition will become true and display "pea" to terminal. This is the reason why the code segment 1 only work for the values of str that contain "pea".

Answer:

The program in cpp for the given scenario is shown below.

#include <stdio.h>

#include <iostream>

#include <fstream>

#include <queue>

using namespace std;

int main()

{

   //object created of file stream

   ofstream out, out1;

   //file opened for writing

   out.open("words.txt");

   out1.open("word.txt");

   //queues declared for two files

   queue<string> first, second;

   //string variables declared to read from file

   string s1, s2;

   //object created of file stream

   ifstream one("words.txt");

   ifstream two("word.txt");

   //first file read into the que

   while (getline(one, s1)) {

       first.push(s1);

   }

   //second file read into the queue

   while (getline(two, s2)) {

       second.push(s2);

}

   //both files compared

   if(first!=second)

        cout<<"files are not the same"<<endl;

   else

        cout<<"files are identical"<<endl;

   //file closed

   out.close();

   return 0;

}

OUTPUT:

files are identical

Explanation:

1. The object of the file output stream are created for both the files.

2. The two files are opened using the objects created in step 1.

3. The objects of the file input stream are created for both the files.

4. The queues are declared for both the files.

5. Two string variables are declared.

6. Inside a while loop, the text from the first is read into the string variable. The value of this string variable is then inserted into the queue.

7. The loop continues till the string is read and end of file is not reached.

8. Inside another while loop, the text from the second file is read into the second string variable and this string is inserted into another queue.

9. The loop continues till the end of file is not reached.

10. Using if-else statement, both the queues are compared.

11. If any character in the first queue does not matches the corresponding character of the second queue, the message is displayed accordingly.

12. Alternatively, if the contents of both the queues match, the message is displayed accordingly.

13. In the given example program, the message is displayed as "files are identical." This is because both the files are empty and the respective queues are considered identical since both the queues are empty.

14. Since queues are used, the queue header file is included in the program.

15. An integer value 0 is returned to indicate successful execution of the program.

Answer:

C. spectrum used by most mobile phone firms that does not travel well through solid objects.

Explanation:

Obstructions on the path of radio waves can result to poor network coverage. This is also called Phone reception or coverage black spot. Just as an obstruction on the path of light waves causes the emergence of shadows, so also an obstruction from waves coming from the cell tower. Common culprits are windows, doors, roofing materials, and walls. These solid objects cause an interruption of network for network providers inside a building.

The use of antennas connected from outside the building to inside can be helpful in reducing the effect of this obstruction. Problems resulting could be low signal, difficulty hearing a caller at the other end, slow internet connection, etc.

Answer:

import java.util.Scanner;

public class nu3 {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Enter number of cycles");

       int numCycles = in.nextInt();

       //Call the method

       printShampooInstructions(numCycles);

   }

   public static void printShampooInstructions(int numCycles){

                if (numCycles<1){

              System.out.println("Too few");

          }

          if (numCycles>4){

              System.out.println("Too Many");

          }

          else {

              for (int i = 1;i <= numCycles; i++) {

                  System.out.println( numCycles+ ": Lather and rinse");

                  numCycles--;

              }

              System.out.println("     Done");

          }

   }

}

Explanation:

This is solved using Java programming language

The method printShampooInstructions() is in bold in the answer section

I have also provided a complete program that request user to enter value for number of cycles, calls the method and passes that value to it

The logic here is using if .... else statements to handle the different possible values of Number of cycles.

In the Else Section a loop is used to decrementally print the number of cycles
