Answer:
Explanation:
I believe that the best course of action would be to divide the companies computers and run the critical applications on half of the systems while the other half update to the latest Ubuntu release. Once that half is done updating, you run the applications on the updated systems and update the other half of the systems. This will allow the company to continue its operations without any downtime, while also updating to the latest Ubuntu release on all systems and making sure that all systems do not have any security vulnerabilities due to outdated software.
You have been given an encrypted copy of the Final exam study guide here, but how do you decrypt and read it???
Along with the encrypted copy, some mysterious person has also given you the following documents:
helloworld.txt -- Maybe this file decrypts to say "Hello world!". Hmmm.
hints.txt -- Seems important.
In a file called pa11.py write a method called decode(inputfile,outputfile). Decode should take two parameters - both of which are strings. The first should be the name of an encoded file (either helloworld.txt or superdupertopsecretstudyguide.txt or yet another file that I might use to test your code). The second should be the name of a file that you will use as an output file. For example:
decode("superDuperTopSecretStudyGuide.txt" , "translatedguide.txt")
Your method should read in the contents of the inputfile and, using the scheme described in the hints.txt file above, decode the hidden message, writing to the outputfile as it goes (or all at once when it is done depending on what you decide to use).

For the recursive method below, list the base case and the recursive statement, then show your work for solving a call to the recur() method using any parameter value 10 or greater.
public static int recur(int n)
{
if(n < 1)
{
return 3;
}
else
{
return recur(n / 5) + 2;
}
}
Answer:
(a): The base case: if(n<1)
(b): The recursive statement: recur(n / 5)
(c): Parameter 10 returns 7
Explanation:
Given
The above code segment
Solving (a): The base case:
The base case is that, which is used to stop the recursion. i.e. when the condition of the base case is true, the function is stopped.
In the given code, the base case is:
if(n<1)
Solving (b): The recursive statement:
The recursive statement is the statement within the function which calls the function.
In the given code, the recursive statement is:
recur(n / 5)
Solving (c): A call to recur() using 10
The base case is first tested
if (n < 1); This is false because 10 > 1
So, the recursive statement is executed
recur(n/5) +2=> recur(10/5)+2 => recur(2)+2
2 is passed to the function, and it returns 2
if (n < 1); This is false because 2 > 1
So, the recursive statement is executed
recur(n/5) +2=> recur(2/5)+2 => recur(0)+2
2 is passed to the function, and it returns 2
if (n < 1); This is true because 0 < 1
This returns 3
So, the following sum is returned
Returned values = 2 + 2 + 3
Returned values = 7
6.12 LAB: Warm up: Parsing strings (1) Prompt the user for a string that contains two strings separated by a comma. (1 pt) Examples of strings that can be accepted: Jill, Allen Jill , Allen Jill,Allen Ex: Enter input string: Jill, Allen (2) Report an error if the input string does not contain a comma. Continue to prompt until a valid string is entered. Note: If the input contains a comma, then assume that the input also contains two strings. (2 pts)
Answer:
Explanation:
The following code is written in Python. It is a loop that asks the user for an input. If it contains a comma then it removes whitespace, splits it into two words, and prints each word seperately, and exits the loop. If it does not contain a comma then it prompts the user for another input.
while True:
string = input("Enter input string: ")
if ',' in string:
string = string.replace(" ", '')
string_split = string.split(',')
print("First word: " + string_split[0])
print("Second word: " + string_split[1])
break

script code written in many languages of the best known: ( C#_PHP_HTML)
Answer:
PHP
Explanation:
The best way to answer this question is to interpret it as, which of the three is a scripting language.
Analyzing each of the languages
1. C#
C# is not a scripting language, but instead it is an object-oriented programming language. Also, c# is a compiled language and one of the features of scripting language is that, they are interpreted.
2. PHP
Basically, PHP are used for server side scripting language because it uses scripts and its programs are not for general purpose runtime environment (but instead for special runtime environments).
3. HTML
HTML is neither a programming language, nor a scripting language because its design pattern does not follow that or programming and scripting languages, and it can not perform what an actual programming and scripting language do.
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","")
Contents of Mytext.txt
Python is an interpreted, high-level, programming language.
Python is dynamically typed and garbage-collected.
Python was conceived in the late 1980s.
Python 2.0, was released in 2000.
Python 3.0, was released in 2008.
The interpreters are available for many operating systems.
Answer:
The function in Python is as follows:
def search_file(filename,mystring):
my_dict = {}
count = 0
file = open(filename)
lines = file.readlines()
for line in lines:
count+=1
if mystring.lower() in line.lower():
my_dict[count] = line.rstrip('\n')
return my_dict
Explanation:
This defines the function
def search_file(filename,mystring):
This initializes an empty dictionary
my_dict = {}
This initializes the number of lines to 0
count = 0
This opens the file
file = open(filename)
This reads the lines of the file
lines = file.readlines()
This iterates through the lines
for line in lines:
This increments the number line
count+=1
This checks if the string exists in the line
if mystring.lower() in line.lower():
If yes, the line number and the string are added to the dictionary
my_dict[count] = line.rstrip('\n')
This returns the dictionary
return my_dict

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());
}

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.
1 # you can write to stdout for debugging purposes, e.g.
2 # print("this is a debug message")
3
4 def solution (riddle):
5
6 # write your code in Python 3.6
7 pass
Answer:
The function is as follows:
import random
import string
def solution(riddle):
s = list(riddle)
for i in range(len(riddle)):
alpha = "".join(random.choice(string.ascii_letters) for x in range(1))
alpha = alpha.lower()
if s[i] == '?':
if i > 0 and i < len(s)-1:
if s[i+1] != alpha:
s[i] = alpha
elif s[i-1] != alpha:
s[i] = alpha
else:
i=i
else:
if i == 0:
if s[1] != alpha:
s[i] = alpha
else:
i = i
else:
if s[i-1] != alpha:
s[i] = alpha
else:
i = i
riddle = ""
for ele in s:
riddle+=ele
return riddle
Explanation:
See attachment for explanation where comments are used to explain some lines
In this exercise we have to use the knowledge of the python language to write the code, so we have to:
The code is in the attached photo.
So to make it easier the code can be found at:
import random
import string
def solution(riddle):
s = list(riddle)
for i in range(len(riddle)):
alpha = "".join(random.choice(string.ascii_letters) for x in range(1))
alpha = alpha.lower()
if s[i] == '?':
if i > 0 and i < len(s)-1:

Which XXX completes the definition of the generic method, avgNum?
public class FindAverage { XXX { long tripleSum; tripleSum = item1.longValue() + item2.longValue() + item3.longValue(); return tripleSum / 3; } }
a. public static long avgNum(long item1, long item2, long item3)
b. public static long avgNum(TheType item1, TheType item2, TheType item3)
c. public static long avgNum(TheType item1, TheType item2, TheType item3)
d. public static avgNum(TheType item1, TheType item2, TheType item3)
Answer:
Explanation:
The correct piece of code for the generic method in the question would be the following...
public static <TheType extends Number> long avgNum(TheType item1, TheType item2, TheType item3)
This declaration of the avgNum method declares this method as a Generic TheType method that is a subclass of the Number class. It also takes in generic parameters which are the same as the Generic class that was declared. Finally, outputting a long value which would be tripleSum / 3

Explanation:
Please specify which programming language this is supposed to be written in.
Without knowing that, only the last part can be answered "how many different initial speeds will you need to test this code?"
You will need to test at least 3 initial speeds: one below the lower-set-speed, one between the lower- and upper-set-speed and last one which is above the upper-set-speed.
Write a method maxMagnitude() with two integer input parameters that returns the largest magnitude value. Use the method in a program that takes two integer inputs, and outputs the largest magnitude value.
Ex: If the inputs are: 5 7 the method returns: 7
Ex: If the inputs are: -8 -2 the method returns: -8
Answer:
The program in Java is as follows:
import java.util.*;
import java.lang.Math;
public class Main{
public static int maxMagnitude(int num1, int num2){
int mag = num2;
if(Math.abs(num1) > Math.abs(num2)){
mag = num1;
}
return mag;
}
public static void main(String[] args) {
int num1, num2;
Scanner input = new Scanner(System.in);
System.out.print("Enter two integers: ");
num1 = input.nextInt();
num2 = input.nextInt();
System.out.println(maxMagnitude(num1,num2));
}
}
Explanation:
The method begins here
public static int maxMagnitude(int num1, int num2){
This initializes the highest magnitude to num2
int mag = num2;
If the magnitude of num1 is greater than that of num2
if(Math.abs(num1) > Math.abs(num2)){
mag is set to num1
mag = num1;
}
This returns mag
return mag;
}
The main method begins here
public static void main(String[] args) {
This declares num1 and num2 as integer
int num1, num2;
Scanner input = new Scanner(System.in);
This prompts the user for two integers
System.out.print("Enter two integers: ");
This gets input for the first integer
num1 = input.nextInt();
This gets input for the second integer
num2 = input.nextInt();
This calls the maxMagnitude method and prints the number with the highest magnitude
System.out.println(maxMagnitude(num1,num2));
}

You use the fixed manipulator to Group of answer choices round floating-point numbers that are displayed in fixed-point notation to the specified number of decimal places round floating-point numbers that are displayed in scientific notation to the specified number of significant digits format floating-point numbers in fixed-point notation all of the above a and b only
Answer:
format floating-point numbers in fixed-point notation
Explanation:
Required
Function of fixed manipulator
This question will be answered from the perspective of C++ programming language (however, the explanation is applicable to programming languages that uses fixed manipulators)
Fixed manipulators in C++ is used to set floating point numbers to a stated fixed point.
Take for instance;
double pi = 3.1415926534;
cout.precision(2);
cout<< fixed << pi;
The third line of the program where the fixed manipulator is used to format pi to 2 fixed point notation.
Hence, the output will be 3.14
