Answer:
D. return str.substring(0, 1) + removeDupChars(str.substring(1));
Explanation:
The logic here is following:
If the there are consecutive duplicate characters, return the removeDupChars method. The parameter of the removeDupChars method is a string, but the duplicate of the first character is removed from the string. The else-if part of the program does this job.
If the consecutive characters are not duplicated, return the first character of the string and the removeDupChars method. The parameter of the removeDupChars method is the rest of the string characters. The else part of the program does this job.
When the length of the str becomes one (or when the str is null), the program reaches its base and returns the str. The if part of the program does this job.
A recursive function is that function that calls itself from within.
The code statement that can replace the comment /* missing code */ is (d) return str.substring(0, 1) + removeDupChars(str.substring(1));
The function definition is given as:
removeDupChars(String str)The function has 3 linked conditional statements, each of which perform three different functions.
The first works for a null string and single characterThe second and the third are to return the intended string for strings with multiple lengths.For the third condition to work, the consecutive characters must not be duplicated.
So, the code statement that does this is (d) return str.substring(0, 1) + removeDupChars(str.substring(1));

Explanation:
Write a program that reads the lengths of the sides of a triangle from the user. Compute the area of the triangle using Heron's formula (below), in which s represents half of the perimeter of the triangle and a, b, and c represent the lengths of the three sides. Print rhe area to three decimal places.
Area= √ s(s-a)(s-b)(s-c)
Answer:
The java program is as follows.
import java.util.Scanner;
import java.lang.*;
public class Area
{
//variables to hold the values
static double a, b, c;
static double s;
static double area;
public static void main(String[] args) {
//scanner class object created
Scanner sc = new Scanner(System.in);
System.out.print("Enter the first side: ");
a=sc.nextInt();
System.out.print("Enter the second side: ");
b=sc.nextInt();
System.out.print("Enter the third side: ");
c=sc.nextInt();
s=(a+b+c)/2;
//function of Math class used
area = Math.sqrt( s*(s-a)*(s-b)*(s-c) );
//result displayed with 3 decimal places
System.out.printf("The area of the triangle is %.3f", area);
}
}
OUTPUT
Enter the first side: 1
Enter the second side: 1
Enter the third side: 1
The area of the triangle is 0.433
Explanation:
1. The variables to declare the three sides of the triangle, the semi-perimeter and the area of the triangle are declared with double datatype. All the variables are declared at class level and hence, declared with keyword, static.
2. Inside main(), an object of the Scanner class is created.
Scanner sc = new Scanner(System.in);
3. Using the Scanner class object, user input is taken for all the three sides of the triangle.
4. Following this, the semi-perimeter is computed as shown.
s=(a+b+c)/2;
5. The area of the triangle is computed using the given formula which is implemented as shown.
area = Math.sqrt( s*(s-a)*(s-b)*(s-c) );
6. The sqrt() method of the Math class is used while computing the area of the triangle.
7. The area is displayed with three decimals. This is done using the printf() method as shown.
System.out.printf("The area of the triangle is %.3f", area);
8. The program is saved with the same name as the name of the class having the main() method.
9. The class having the main() method is always public.
You are currently working in a mid-tier accounting firm. In an engagement meeting with a client, the management of your client is concerned that the audit tests that you perform will disrupt operations. Your client has recently implemented a data warehouse and the management suggests that you draw the data for analytical reviews and substantive testing from the data warehouse instead of the operational database. The management points out that operational data are copied weekly into the data warehouse and all data you need are contained there. Outline your response to the management’s proposal and mention any concerns you might have. (maximum 300 words)

The answer "Only when an auditor is free to perform his responsibilities should the audit contract be accepted. There should be no stress on an investigator but no independence".
Explanation:
In the essence of the data store, huge storage of the information, that is used to collect from either a variety of sources within the same company. The DTC is often used as an analytics capability (OLAP frameworks) because a transfer can be focussed on the data structure. It's also currently easier for organizations to end things or assessment and determine the best information with full of data from one destination.
Create a complete warehouse: It is unlikely, however, that each one of your getting your information at that same single place seems to be the greatest flexibility for providing a database server.
Below are various benefits of providing data storage:
Saving time: In the company's ease of accessing data from different sources at the data center, that ensures no time to obtain information from other sources is lost. Higher trust: Its data is automatically moved into your data center in an ordered structure, rather than being replaced by human activity, as you'll be more sure that your information is nice and clean, complete and accurate. Growing knowledge: In the data, the warehouse designs the information so that it can be easily analyzed. Increasing quality: it would be far easier to manage individuals who reach your data whenever an association position is integrated. Data warehouse allows security fully flexible, allowing users to access all the systems and lock all of them.Following are its specific approach to creating a data center, which will you need to develop the core architecture in three sections:
The stocking(storage) algorithm, Software and working HR.Storage: it's the foundation of the structure and your warehouse lives there. The inner server is the client's office 's internal device as well as the cloud is an electronic storage solution that relies on external servers.
Software: It is a valuable method of private cloud architectural design. For two classes, centralization and visual imagery are commonly isolated.
Human resources: It is the part of data warehouse operations which is extremely important for a workable example. To keep your warehouse running, you must use new circumstances in your company.

b) that can ensure the confidentiality of the classified data but not its integrity
c) that can ensure neither the confidentiality of the classified data nor its integrity
d) that can't ensure the confidentiality of the classified data but can its integrity
Answer:
Option (b) is the correct answer to this question.
Explanation:
BLP model can ensure classified data confidentiality, but it is not integrity. The Bell-LaPadula model is about secrecy. As just that, having read information would jeopardize privacy and security at a greater position than what has been permitted. The Bell – LaPadula Model (BLP) is a finite state model being used for political and police installations to implement authentication.Other options are incorrect because they are not related to the given scenario.
What will happen if registers are excluding the address register (Memory Address Register - MAR)?
Answer: Memory address register captures and stores the memory address in CPU.
Explanation:
It stores the address of the data which is required to be sent and stored to specific location of the computer.It stores the next address of the data to be stored read or written.
If the memory address register is excluded in the system then the storage of memory will be compromised.
Computer has many functions. MAR is known to have the memory location of data that one needs to be accessed and if it is excluded, there is a compromise and one cannot get the data needed as it will be inaccessible.
What is the Memory Address Register?In a computer, the Memory Address Register (MAR) is known to be the CPU register that often stores the memory address through which one can get data to the CPU.It is also known as the address to which data is often sent to or stored. That is, MAR has the power to the memory location of data that one needs to be accessed.

Industrial Products is a small light-manufacturing firm that produces a variety of control systems for heavy industry. It has a network that connects its office building and warehouse that has functioned well for the last year, but over the past week, users have begun to complain that the network is slow. Clarence Hung, the network manager, did a quick check of the number of orders over the past week and saw no real change, suggesting that there has been no major increase in network traffic. What would you suggest that Clarence do next?
Answer and Explanation:
The suggestions are as follows
1. There may be a faulty configuration that leads to packet losses, those packets lost are retransmitted over and over again that may have caused network slowing down.
2. The route or direction for the transmission of packets over the network can shift, which in effect increases the time for the transmission of packets and thus leads to a slowed-down network.
3. Probability is the authentication server that would take too much time to respond.
4. There may be some applications that produce errors for certain requests and therefore fail to complete the process on time. The failures may be on the front end of the server or back end.
Upgrading the apps to new versions will solve the issue, as the upgraded software involve different fixes.
5. Users will be tested on what they're doing on their devices. Unacceptable use of the network services can also result to a network slow- down.
6. Certain bad cable connexions or poor signal strength can result in network slowing down.
The data files from a computer-assisted questionnaire software program can be downloaded at the researcher's discretion; however, different formatting options, including SPSS-readable files, may not be available. Group of answer choices True False
Answer:
False.
Explanation:
When data files are sourced from a computer-assisted questionnaire software program. The data files can be downloaded at the researcher's discretion, different formatting options can be used on the data files, and SPSS (Statistical Product and Service Solutions)-readable files are also available.
For instance, the CAPI (Computer-Assisted Personal Interview), CAWI (Computer-Assisted Web Interview) and CASI (Computer-Assisted Self Interview) software program collects data from potential targeted population in a survey. These data can be downloaded by the originator of the survey with its SPSS (Statistical Product and Service Solutions)-readable files.
Also, if the researcher wishes to edit or format the data, it is very possible to achieve.
