Design a Python3 function to compare every prefix of a string X to every element of string Y, if there is a match, place it in a python set, sort and reversely sort the set, and return the sorted and reversely sorted sets.

Answer:

The function is as follows:

def compare_prefix(strX,strY):    

   prefix=set()

   for i in range(len(strX)):

       for j in range(i+1,len(strX)):

           chk =strX[i:j+1]

           if chk in strY:

               prefix.add(chk)

   sort_prefix = sorted(prefix)

   rev_sort_prefix = sorted(prefix,reverse=True)

   return(sort_prefix,rev_sort_prefix)

Explanation:

This defines the function

def compare_prefix(strX,strY):    

This creates an empty set, prefix

   prefix=set()

This iterates through each character in strX

   for i in range(len(strX)):

This iterates through every other character in strX

       for j in range(i+1,len(strX)):

This gets the prefix of strX by concatenating strings from i to j + 1

           chk =strX[i:j+1]

This checks if the prefix is in strY

           if chk in strY:

If yes, the string is added to set prefix

               prefix.add(chk)

This sorts prefix

   sort_prefix = sorted(prefix)

This reverses the sorted prefix

   rev_sort_prefix = sorted(prefix,reverse=True)

This returns the sorted and reversed prefix

   return(sort_prefix,rev_sort_prefix)

Which of the following best explains how an analog audio signal is typically represented by a computer?
a. An analog audio signal is measured at regular intervals. Each measurement is stored as a sample, which is represented at the lowest level as a sequence of bits.
b. An analog audio signal is measured as a sequence of operations that describe how the sound can be reproduced. The operations are represented at the lowest level as programming instructions.
c. An analog audio signal is measured as input parameters to a program or procedure. The inputs are represented at the lowest level as a collection of variables.
d. An analog audio signal is measured as text that describes the attributes of the sound. The text is represented at the lowest level as a string.

Create a PetStore class, a Dog class, and Cat class. Once instantiated, a PetStore should be able to take in and give out pets. The store's method for receiving pets should be called receive. This method should take a single pet object (either a Dog or Cat instance) and should add it to the store's inventory of pets. The store's method for giving out a pet should be called sell and can take no arguments. The method returns a pet when called.

Rick is a fan of logic-based games. However, he is bored of the classic ones, like Sudoku and Mastermind, since he has solved so many of them. Recently he found a new game in which one is given a string with some question marks in it. The objective is to replace all of the question marks with letters (one letter per question mark) in such a way that no letter appears next to another letter of the same kind.
Write a function:
def solution(riddle)
that, given a string riddle, returns a copy of the string with all of the question marks replaced by lowercase letters (a-z) in such a way that the same letters do not occur next to each other. The result can be any of the possible answers as long as it fulfils the above requirements.
Examples:
1. Given riddle = "ab?ac?", your function might return "abcaca". Some other possible results are 'abzacd", "abfacf".
2. Given riddle = "rd?e?wg??", your function might return "rdveawgab".
3. Given riddle = "????????", your function might return "codility".
Write an efficient algorithm for the following assumptions:
• the length of the string is within the range [1..100,000);
• string riddle consists only of lowercases letters (a - z) or '?';
• it is always possible to turn string 'riddle' into a string without two identical consecutive letters.

2 # print("this is a debug message")

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());

Python program
You are given the following text file called Mytext.txt. Write a Python function called search_file that accepts the name of the file (i.e. filename) and a string to look for in the file (i.e. mystring) as parameters. The function then looks for mystring in the file. Whenever it finds the string in a line, it saves the line number and the text for that line in a dictionary. Finally, it returns the dictionary after reading all the lines in the file and populating the dictionary with all matching line numbers and line text. If an empty string or a blank string is passed as mystring then an empty dictionary is returned.
Sample Input: search_file("Mytext.txt","python")
Sample Input: search_file("Mytext.txt","")

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"

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.

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
