Design a class named Complex for representing complex numbers and the methods add, subtract, multiply, divide, abs for performing complex-number operations, and override toString method for returning a string representation for a complex number. The toString method returns a + bi as a string. If b is 0, it simply returns a.
Provide three constructors Complex(a, b), Complex(a), and
Complex(). Complex() creates a Complex object for number 0 and
Complex(a) creates a Complex object with 0 for b. Also provide
the getRealPart() and getImaginaryPart() methods for returning
the real and imaginary part of the complex number, respectively.
Your Complex class should also implement the Cloneable
interface.
Write a test program that prompts the user to enter two complex numbers and display the result of their addition, subtraction, multiplication, and division.
Here is the main class. It cannot be changed.
import java.util.Scanner;
public class Test {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter the first complex number: ");
double a = input.nextDouble();
double b = input.nextDouble();
Complex c1 = new Complex(a, b);
System.out.print("Enter the second complex number: ");
double c = input.nextDouble();
double d = input.nextDouble();
Complex c2 = new Complex(c, d);
System.out.println("(" + c1 + ")" + " + " + "(" + c2 + ")" + " = " + c1.add(c2));
System.out.println("(" + c1 + ")" + " - " + "(" + c2 + ")" + " = " + c1.subtract(c2));
System.out.println("(" + c1 + ")" + " * " + "(" + c2 + ")" + " = " + c1.multiply(c2));
System.out.println("(" + c1 + ")" + " / " + "(" + c2 + ")" + " = " + c1.divide(c2));
System.out.println("|" + c1 + "| = " + c1.abs());
Complex c3 = (Complex)c1.clone();
System.out.println(c1 == c3);
System.out.println(c3.getRealPart());
System.out.println(c3.getImaginaryPart());
}
}

Explanation:
The following code is written in Java, it creates the entire complex class as requested so that it works with the main method that has been provided in the question without having to change anything in the main method. Proof of output can be seen in the attached picture below
import java.util.Scanner;
class Test implements Cloneable{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter the first complex number: ");
double a = input.nextDouble();
double b = input.nextDouble();
Complex c1 = new Complex(a, b);
System.out.print("Enter the second complex number: ");
double c = input.nextDouble();
double d = input.nextDouble();
Complex c2 = new Complex(c, d);
System.out.println("(" + c1 + ")" + " + " + "(" + c2 + ")" + " = " + c1.add(c2));
System.out.println("(" + c1 + ")" + " - " + "(" + c2 + ")" + " = " + c1.subtract(c2));
System.out.println("(" + c1 + ")" + " * " + "(" + c2 + ")" + " = " + c1.multiply(c2));
System.out.println("(" + c1 + ")" + " / " + "(" + c2 + ")" + " = " + c1.divide(c2));
System.out.println("|" + c1 + "| = " + c1.abs());
Complex c3 = c1;

System.out.println(c3.getRealPart());
System.out.println(c3.getImaginaryPart());

The L-exclusion problem is a variant of the starvation-free mutual exclusion problem. We make two changes: as many as L threads may be in the critical section at the same time, and fewer than L threads might fail (by halting) in the critical section. An implementation must satisfy the following conditions:_____.
L-Exclusion: At any time, at most L threads are in the critical section.
L-Starvation-Freedom: As long as fewer than L threads are in the critical section, then some thread that wants to enter the critical section will eventually succeed (even if some threads in the critical section have halted).
Modify the n-process Bakery mutual exclusion algorithm to turn it into an L-exclusion algorithm. Do not consider atomic operations in your answer. You can provide a pseudo-code solution or written solution.
Answers
Answer:
The solution is as follows.
class LFilters implements Lock {
int[] lvl;
int[] vic;
public LFilters(int n, int l) {
lvl = new int[max(n-l+1,0)];
vic = new int[max(n-l+1,0)];
for (int i = 0; i < n-l+1; i++) {
lvl[i] = 0;
}
}
public void lock() {
int me = ThreadID.get();
for (int i = 1; i < n-l+1; i++) { // attempt level i
lvl[me] = i;
vic[i] = me;
// rotate while conflicts exist
int above = l+1;
while (above > l && vic[i] == me) {
above = 0;
for (int k = 0; k < n; k++) {
if (lvl[k] >= i) above++;
}
}
}
}
public void unlock() {
int me = ThreadID.get();
lvl[me] = 0;
}
}
Explanation:
The code is presented above in which the a class is formed which has two variables, lvl and vic. It performs the operation of lock as indicated above.

A security team has downloaded a public database of the largest collection of password dumps on the Internet. This collection contains the cleartext credentials of every major breach for the last four years. The security team pulls and compares users' credentials to the database and discovers that more than 30% of the users were still using passwords discovered in this list. Which of the following would be the BEST combination to reduce the risks discovered?
a. Password length, password encryption, password complexity
b. Password complexity least privilege, password reuse
c. Password reuse, password complexity, password expiration
d. Group policy, password history, password encryption
Answers
Answer:
a. Password length, password encryption, password complexity
Explanation:
Under this scenario, the best combination would be Password length, password encryption, password complexity. This is because the main security problem is with the user's passwords. Increasing the password length and password complexity makes it nearly impossible for individuals to simply guess the password and gain access, while also making it extremely difficult and time consuming for hackers to use software to discover the password as well. Password excryption would be an extra layer of security as it encrypts the password before storing it into the database, therefore preventing eavesdroppers from seeing the password and leaked info from being used without decryption.

def shared_motif(dna_list):
This function takes in a list of DNA strings and returns the longest common substring. A substring is a contiguous sequence of characters within a string. A common substring is a substring of every element in the given list of DNA strings. Note that the number of DNA strings in the input list is not always the same! There may be multiple solutions, but you only need to return the first one.
Example:
Sample input DNA list:
("GATTACA", "TAGACCA", "ATACA"]
The returned longest common substring:
"TA"

Explanation:
The following code is written in Python, the function creates various nested loops to loop through each individual string comparing letter by letter in order to find the longest common substring. Finally, returning the substring itself.

A train protection system automatically applies the brakes of a train if the speed limit for a segment of track is exceeded, or if the train enters a track segment that is currently signaled with a red light (i.e., the segment should not be entered). There are two critical-safety requirements for this train protection system:
The train shall not enter a segment of track that is signaled with a red light.
The train shall not exceed the specified speed limit for a section of track.
Assuming that the signal status and the speed limit for the track segment are transmitted to on-board software on the train before it enters the track segment, propose five possible functional system requirements for the onboard software that may be generated from the system safety requirements.
Answers
Explanation:
Five possible functional system requirements for the onboard software that may be generated from the system safety requirements:
software should enable the brakes to be applied instantly when the red light is signaled.speed of the train should be monitored when it's running on a segment so that it does not exceed the maximum speed limit.important for the system to examine the color displayed before a train enters a segment of the track.constant checking of the speed limit and color of the light so as to determine when the brakes should be applied. when there is a red light the system should notify/prevent the train from entering the segment.Write a C program that right shifts an integer variable 4 bits.
