Answer:
Following are the code to this question:
public class Locker //defining a class Locker
{
public static void main(String[] ax)//defining main method
{
boolean[] locker = new boolean[101]; //defining boolean array locker that's size is 100.
int j,s1,k1,x;
x=locker.length;
for (j=1;j<x; j++)//defining loop to assigns value false in locker array
{
locker[j] = false;// assign value false
}
for (j=1;j<x; j++)//defining loop loop to assign value true in array
{
locker[j] = true;//assign value true
}
for(s1=2; s1<x; s1++)//defining loop to count locker from 2nd place
{
for(k1=s1; k1<x; k1=k1+s1)// defining inner loop to assign value
{
if(locker[k1]==false) //defining if block for check false value
{
locker[k1] = true;// if condition is true it assign value true
}
else //defining else block
{
locker[k1] = false;//assign value false in locker array
}
}
}
for(s1=1; s1<x; s1++)//defining loop to print locker value
{
if (locker[s1] == true) //defining if block that check Locker array value is equal to true
{
System.out.println("Locker " + s1 + " Open");//print Locker value with message
}
}
}
}
Output:
Locker 1 Open
Locker 4 Open
Locker 9 Open
Locker 16 Open
Locker 25 Open
Locker 36 Open
Locker 49 Open
Locker 64 Open
Locker 81 Open
Locker 100 Open
Explanation:
In the above code, a class "Locker" is declared, inside the class main method is declared, in which a boolean array "locker" is declared that's size is 100, in the next line fouth integer variable " j,s1,k1, and x" is declared, in which variable x is used to hold the boolean array length value, and other variable used in the loop.
In the next step, two for loop is declared, in the first loop assign value "false" in locker array and in seconde loop it assigns the value "true".In the next step, multiple for loop it uses if block uses to check locker value equal to false then assign value true otherwise assign value false. At the last another loop is declared, that uses if block to check locker value is equal to true and print its value with the message.A security administrator is investigating a report that a user is receiving suspicious emails.

The main path of the Internet along which data travels the fastest is known as the Internet ________. Group of answer choices
Answer:
Internet backbone
Explanation:
The internet backbone is made up of multiple networks from multiple users. It is the central data route between interconnected computer networks and core routers of the Internet on the large scale. This backbone does not have a unique central control or policies, and is hosted by big government, research and academic institutes, commercial organisations etc. Although it is governed by the principle of settlement-free peering, in which providers privately negotiate interconnection agreements, moves have been made to ensure that no particular internet backbone provider grows too large as to dominate the backbone market.
#Write a function called random_marks. random_marks should #take three parameters, all integers. It should return a #string. # #The first parameter represents how many apostrophes should #be in the string. The second parameter represents how many #quotation marks should be in the string. The third #parameter represents how many apostrophe-quotation mark #pairs should be in the string. # #For example, random_marks(3, 2, 3) would return this #string: #'''""'"'"'" # #Note that there are three apostrophes, then two quotation #marks, then three '" pairs. #Add your function here!
Answer:
def random_marks(apostrophe, quotation, apostrophe_quotation):
return "'"*apostrophe + "\""*quotation + "'\""*apostrophe_quotation
print(random_marks(3, 2, 3))
Explanation:
Create a function called random_marks that takes apostrophe, quotation, and apostrophe_quotation as parameters. Inside the function, return apostrophe sign times apostrophe plus quotation mark times quotation plus apostrophe sign quotation mark times apostrophe_quotation.
Note that plus sign (+) is used to concatenate strings. Also, if you multiply a string with a number, you get that number of strings ("#"*3 gives ###).
Then, call the function with given parameters and print

Explanation:
In the above code, a char array "name" and integer variables "A, E, I, O, U, i, value and l" declared, in which name array store 50 character value, which uses the gets function to take string value.after input value strlen method is used to store the length of the input string in l variable.In the next step, for loop is declared that uses multiple conditional statements to counts vowels and the values of the digits,if it is more then one it increments its value and at the last print method is used to print its count's value.Convert the following numbers from decimal to binary, assuming unsigned binary representation:________.
A) 35
B) 3
C) 27
D) 16
Answer:
Binary representations of following are:
A) 35 = 100011
B) 3 = 11
C) 27 = 11011
D) 16 = 10000
Explanation:
The method to generate the binary number from a decimal is :
Keep on dividing the number by 2 and keep on tracking the remainder
And the quotient is again divided and remainder is tracked so that the number is completely divided.
And then write the binary digits from bottom to top.
Please have a look at the method in below examples:
A) 35
[tex]\begin{center}\begin{tabular}{ c c c }Number & Quotient & Remainder\\ 2 & 35 & 1 \\ 2 & 17 & 1 \\ 2 & 8 & 0 \\ 2 & 4 & 0 \\ 2 & 2 & 0 \\ 2 & 1 & 1\end{tabular}\end{center}[/tex]
Writing the remainder from bottom to top.
So, binary number is 100011
B) 3
[tex]\begin{center}\begin{tabular}{ c c c }Number & Quotient & Remainder\\ 2 & 3 & 1 \\ 2 & 1 & 1 \\ \end{tabular}\end{center}[/tex]
Writing the remainder from bottom to top.
So, binary equivalent is 11.
C) 27
[tex]\begin{center}\begin{tabular}{ c c c }Number & Quotient & Remainder\\ 2 & 27 & 1 \\ 2 & 13 & 1 \\ 2 & 6 & 0 \\ 2 & 3 & 1 \\ 2 & 1 & 1 \end{tabular}\end{center}[/tex]
Writing the remainder from bottom to top.
So, binary equivalent is 11011.
D) 16
[tex]\begin{center}\begin{tabular}{ c c c }Number & Quotient & Remainder\\ 2 & 16 & 0 \\ 2 & 8 & 0 \\ 2 & 4 & 0 \\ 2 & 2 & 0 \\ 2 & 1 & 1 \\\end{tabular}\end{center}[/tex]
Writing the remainder from bottom to top.
So, binary equivalent is 10000.

True or False: It is okay to just paste the URLs of the items you used for references at the end of a paper. Select one: True False
It is not okay to just paste the URLs of the items you used for references at the end of a paper therefore the answer is False
For better understanding, lets explain why the answer is false
When citing a reference it not OK to cite URLs. when you are citing onlh the URL is wrong because theURL could change at any time and the fact remain that it is not everyone who reads your paper can do it electronically or has access to the internet., so the url is not the first step to take. The right thing to do is to give the name of the paper, the author(s), the Journal it was published in and the year it was published.
From the above, we can therefore say that the answer is It is not okay to just paste the URLs of the items you used for references at the end of a paper therefore the answer is False, is correct.

What's the value of this Python expression? ((10 >= 5*2) and (10 <= 5*2))
Answer:
The Boolean value returned by that expression will be True
Explanation:
We have two logical statements in that expression:
Expression 1: (10 >= 5*2)
This can be read as: is 10 greater than or equal to 5 multipled by 2. This evaluates to true as 10 is equal to 5 * 2. Hence expression 1 returns true
Expression 2: (10 <= 5*2)
This can be read as: is 10 less than or equal to 5 multiplied by 2. This also evaluates to true as 10 is equal to 5*2. Hence expression 2 returns true.
Now between this two expression is the and operator which evaluates to true if and only if both logical expressions returnes true.
True and True ==> True
Since Expression 1 ==> True and Expression 2 ==> True
This means Expression 1 and Expression 2 ==> True which is the Boolean value returned by the statement
The value of the python expression ((10 >= 5*2) and (10 <= 5*2)) is True
The code will definitely return a Boolean value(True or False).
For the expression to be True , the two statements must be True. The AND gate returns True if the whole statement is True.
(10 >= 5*2) is True because 10 is equals to 5 × 2 = 10.
(10 <= 5*2) is True because 10 is equals to 5 × 2 = 10.
The two statements are True . Therefore,
True and True = True.

C) Sharing knowledge through informal conversations, for example, during lunch breaks.
D) Sharing best practices, lessons learnt and other topics in a central place where team can collaborate
Answer: D) Sharing best practices, lessons learned and other topics in a central place where the team can collaborate
Explanation: Knowledge sharing within a team is usually an important aspect of building a strong and efficient team. Acquiring knowledge usually comes from the experience gathered from previous projects, learning, or tips learned from various sources. Therefore, sharing knowledge is always a good way to ensure that what is gained is sustained by letting others know. Sharing and sustaining knowledge is most effective when transmitted or aired to a group of people usually a team gathered in an interactive setting which allows members to freely share experience and get feedback, views, or thoughts from other collaborators.
#this is 34 lines -- you can do it! # #In web development, it is common to represent a color like #this: # # rgb(red_val, green_val, blue_val) # #where red_val, green_val and blue_val would be substituted #with values from 0-255 telling the computer how much to #light up that portion of the pixel. For example: # # - rgb(255, 0, 0) would make a color red. # - rgb(255, 255, 0) would make yellow, because it is equal # parts red and green. # - rgb(0, 0, 0) would make black, the absence of all color. # - rgb(255, 255, 255) would make white, the presence of all # colors equally. # #Don't let the function-like syntax here confuse you: here, #these are just strings. The string "rgb(0, 255, 0)" #represents the color green. # #Write a function called "find_color" that accepts a single #argument expected to be a string as just described. Your #function should return a simplified version of the color #that is represented according to the following rules: # # If there is more red than any other color, return "red". # If there is more green than any other color, return "green". # If there is more blue than any other color, return "blue". # If there are equal parts red and green, return "yellow". # If there are equal parts red and blue, return "purple". # If there are equal parts green and blue, return "teal". # If there are equal parts red, green, and blue, return "gray". # (even though this might be white or black). #Write your function here!
Answer:
Following are the code to this question:
def find_color(color):#definig a method find_color that accepts color parameter
color = str(color).replace('rgb(', '').replace(')', '')#definig color variable that convert parameter value in string and remove brackets
r, g, b = int(color.split(', ')[0]), int(color.split(', ')[1]), int(color.split(', ')[2])#defining r,g,b variable that splits and convert number value into integer
if r == g == b:#defining if block to check if r, g, b value is equal
return "gray"#return value gray
elif r > g and r > b:#defining elif block that checks value of r is greater then g and b

print(find_color("rgb(217, 217, 217)"))#using print method to call find_color method that accepts value and print its return value
Output:
red
purple
gray
Explanation:
In the above method "find_color" is declared that uses the color variable as the parameter, inside the method a color variable is declared that convert method parameter value into the string and remove its brackets, and three variable "r,g, and b" is defined. In this variable first, it splits parameter value and after that, it converts its value into an integer and uses the multiple conditional statements to return its calculated value.
if block checks the r, g, and b value it all value is equal it will return a string value, that is "gray" otherwise it will go to elif block. In this block, it checks the value of r is greater then g, and b if it is true it will return a string value, that is "red" otherwise it will go to another elif block. In this block, it checks the value of b is greater then g, and r if it is true it will return a string value, that is "blue" otherwise it will go to another elif block. In this block, it checks the value of g is greater then r and b if it is true it will return a string value, that is "green" otherwise it will go to another elif block. In the other block, it checks r is equal to g or g is equal to b or r is equal to b, it will return the value, that is "yellow" or "teal" or "purple".You are in a rectangular maze organized in the form of M N cells/locations. You are starting at the upper left corner (grid location: (1; 1)) and you want to go to the lower right corner (grid location: (M;N)). From any location, you can move either to the right or to the bottom, or go diagonal. I.e., from (i; j) you can move to (i; j + 1) or (i + 1; j) or to (i+1; j +1). Cost of moving right or down is 2, while the cost of moving diagonally is 3. The grid has several cells that contain diamonds of whose value lies between 1 and 10. I.e, if you land in such cells you earn an amount that is equal to the value of the diamond in the cell. Your objective is to go from the start corner to the destination corner. Your prot along a path is the total value of the diamonds you picked minus the sum of the all the costs incurred along the path. Your goal is to nd a path that maximizes the prot. Write a dynamic programming algorithm to address the problem. Your algorithm must take a 2-d array representing the maze as input and outputs the maximum possible prot. Your algorithm need not output the path that gives the maximum possible prot. First write the recurrence relation to capture the maximum prot, explain the correctness of the recurrence relation. Design an algorithm based on the recurrence relation. State and derive the time bound of the algorithm. Your algorithm should not use recursion
Answer:
Following are the description of the given points:
Explanation:
A) The Multiple greedy approaches could exist, which could be to reach for the closest emergency diamond, and yet clearly we are going to miss some very essential routes in that case. So, it can make every argument quickly, and seek to demonstrate a reference case for that.
B) An approach to the evolutionary algorithm and its users are going to just have states M x N. But each state (i, j) indicates the absolute difference between the amount of the selected diamond and the amounts of the costs incurred.
DP(i, j) = DimondVal(i, j) + max ((DP(i, j-1)-2), (DP(i-1,j-1)-3))
DP(i, j) is a description of the state.
DimondVal(i, j) is the diamond value at (i j), 0 if there is no diamond available.
This states must calculate the states of M N and it involves continuous-time for each State to determine. Therefore the amount of time of such an algo is going to be O(MN).
What are the differences between editing manually and editing digitally? What tools are used for each?
Answer:
Both manual and digital editing are concepts used in proofreading.
Manual editing is also called "hard proofreading" (or "hard proofing" for short). It is the process of proofreading, modifying or revising printed documents. In this type of proofreading, one would normally manually mark parts of the printed documents with editing materials such as ink, pen, marker e.t.c
Digital editing is also called "soft proofing". In contrast to manual editing, this type is done on digital documents. These documents include, but not limited to, DOC, txt, PDF, image, audio and video files.
Tools for editing manually are;
i. pen
ii. ink
iii. tipex
Tools for editing digitally are;
i. Photoshop application
ii. Text editors such as notepad++, Microsoft word
Proofreading has evolved in recent times as a result of advancements in technology. Now, manual proofreading has paved way for digital proofreading, which allows revising of PDF and DOC files. The difference in both forms is as follows:
Manual Editing: In the process of revising or proofing printed documents, one would manually apply standard proofreading marks. Manual editing is also known as "Hard proofing", as the process requires proofreaders to mark the hard copies.
Digital Editing: In the process of revising or proofing digital documents i.e. PDF and DOC files, one would digitally apply the proofreading marks. Thus, corrections and edits are transferred electronically among authors, proofreaders. Digital editing is also known as "Soft proofing", as the process requires proofreaders to mark the soft copies i.e. without using any paper or pen.
There are a number of electronic tools and marks available for both techniques of
proofreading. Some tools used for manual proofreading include- deletion, capitalization, and insertion, close-up, transpose.
Tools used in digital proofreading include- spell check, readability levels, trite expressions, and comment, track changes.

A. A maximum MTTR of 30 minutes
B. A maximum MTBF of 30 minutes
C. A maximum RTO of 60 minutes
D. An SLA guarantee of 60 minutes
Answer:
D. A maximum RPO of 60 minutes
Explanation:
Note that an option is not included in this list of options.
The complete list of options is:
A. A maximum MTTR of 30 minutes
B. A maximum MTBF of 30 minutes
C. A maximum RTO of 60 minutes
D. A maximum RPO of 60 minutes
E. An SLA guarantee of 60 minutes
The Recovery Point Objective tells how old a backup file must be before it can be recovered by a system after failure.
Since the data in the failover systems described in this question must be backup and recovered after the failure, it will be important to include the Recovery Point Objective (RPO) in the Business Continuity Plan.
Since the failover systems must use back up data that is no older than one hour, the backup of the system data must be done at intervals of 60 minutes or less. Meaning that the maximum RPO is 60 minutes.
Note that RPO is more critical than RTO in data backup
A technician is evaluating malware that was found on the enterprise network. After reviewing samples of the malware binaries, the technician finds each has a different hash associated with it. Which of the following types of malware is MOST likely present in the environment?
a. Trojan
b. Polymorphic worm
c. Rootkit
d. Logic bomb
e. Armored virus
Answer:
(b) polymorphic worm
Explanation:
A polymorphic worm can be compared with a chameleon. It changes its color so as to blend with the background of the surrounding to avoid being seen or caught. A polymorphic worm is a special type of worm that keeps changing its constituent features in order to avoid being detected. The most common way in which polymorphic worms hide their codes is by using encryption.
Polymorphic worms have two parts: the part that changes and the one that does not change. The part that changes include the characteristics of the worm such as encryption key, associated hash value e.t.c. The part that does not change is basically its functionality. Therefore, although the characteristics of the worm keep changing, its overall function remains the same.

* Physical address in paired hexadecimal form.
* Physical address expressed in binary form.
Answer:
00000000 11111111 00000011 10111110 10001100 11011010
Explanation:
(i)First, open a command prompt window by using the shortcut: Windows key + X then select command prompt in the list.
(ii)Now type ipconfig/ all and press Enter. This will return a few information
(a) To get the Physical address in paired hexadecimal form, copy any of the Physical Addresses shown. E.g
00-FF-03-BE-8C-DA
This is the hexadecimal form of the physical address.
(b) Now let's convert the physical address into its binary form as follows;
To convert to binary from hexadecimal, we can use the following table;
Hex | Decimal | Binary
0 | 0 | 0000
1 | 1 | 0001
2 | 2 | 0010
3 | 3 | 0011
4 | 4 | 0100
5 | 5 | 0101
6 | 6 | 0110
7 | 7 | 0111
8 | 8 | 1000
9 | 9 | 1001
A | 10 | 1010
B | 11 | 1011
C | 12 | 1100
D | 13 | 1101
E | 14 | 1110
F | 15 | 1111
Now, from the table;
0 = 0000
0 = 0000
F = 1111
F = 1111
0 = 0000
3 = 0011
B = 1011
E = 1110
8 = 1000
C = 1100
D = 1101
A = 1010
Put together, 00-FF-03-BE-8C-DA becomes;
00000000 11111111 00000011 10111110 10001100 11011010

It is pretty much simple to set up and allow for great flexibility. In this network, a single modem can be set up to enable both wired and wireless connections for multiple devices within the building.
Problem You Need to Solve for This Lab:
You are asked to write an app to keep track of a relatively small music library. The app should load song information from a data file once the app is started. It should allow user to view, add, remove, and search for songs. The app should save the data back to the same data file when the program exits.
What Your Program Should Do:
Write an interactive text based menu interface (using a loop) that will allow the user to
ï‚· Enter information for a new song
ï‚· Display information for all the songs in the database with index for each song
ï‚· Remove a song by index
ï‚· Search for songs by a certain artist
ï‚· Search for songs by a certain album
ï‚· Quit
For each song, you need to keep track of:
title
artist
duration
album
Allow the program to keep looping until user wants to quit. When the program starts, it should load the tasks from external file ("songs.txt") into memory. When user enters information about the new song, the program needs to read them in, save them in memory and eventually write them to the external data file ("songs.txt"). The file format could look like:
Stereo Hearts;Gym Class Heroes;3;34;The Papercut Chronicles II
Counting Stars;OneRepulic;4;17;Native
The ';' is used as a delimiter or field separator. Each record ends with a new line character.
Some Implementation Requirements:
Write at least four functions WITH arguments for this assignment.
Use struct named Song to model each song
Use array of structs to model the collection of songs.
Hint: In this assignment, some data fields may have multiple words in it. Therefore,
you now SHOULD read using the 3 argument version of get.
Watch out. When using the 3 argument version of get you need to make sure to
remove the delimiter or newline. Therefore, anytime you read (even a confirmation
message), make sure to eat the newline using cin.ignore(...)!
Make sure to have a delimiter written between each item in the file – like a newline.
This will be important when you read the information back from the file.
For submission, your data file should contain a sufficient set of test data. It should have test cases for same artist with multiple songs and same album with multiple songs in it.
Do-Not List:
No Global Variables (you can have global constants)
Do not use Classes or Linked Lists
You must use cstring and char arrays. (do not use )
No use of the stdio library (use iostream and fstream)
Instead of the string class, you will be using arrays of characters and the cstring library
No STL containers such as vector. You must implement your own array for this class.

(Find the index of the smallest element) Write a function that returns the index of the smallest element in a list of integers. If the number of such elements is greater than 1, return the smallest index. Use the following header: def indexOfSmallestElement(lst): Write a test program that prompts the user to enter a list of numbers, invokes this function to return the index of the smallest element, and displays the index.
Answer:
Here is the function that returns the the smallest element in a list of integers
def indexOfSmallestElement(lst):
smallest = lst.index(min(lst))
return smallest
Explanation:
The function indexOfSmallestElement() takes a list of integers lst as parameter.
smallest = lst.index(min(lst))
In the above statement two methods are used i.e. index() and min().
The first method index returns the index position of the list and the second method min() returns the minimum element of the list.
Now as a whole the statement min() first returns the smallest element in the list (lst) of integers and then the index() method returns the position of that minimum element of lst. At the end the index position of this smallest element in the list (lst) is stored in the smallest variable.
So lets say if we have a list of the following elements: [3,2,1,7,1,8] then min() returns the smallest element in this list i.e. 1 and index() returns the index position of this smallest element. Now notice that 1 occurs twice in the list and index() method only returns the the first index found in the list. So it returns the smallest index of the two index positions of 1 i.e 2. Hence the output is 2.
The test program is given below:
lst=list()
num=int(input("Enter the list size: "))
print("Enter a list of numbers: ")
for i in range(int(num)):
integers=int(input(""))
lst.append(integers)
print("The index of the smallest element is: ")
print(indexOfSmallestElement(lst))
First the list named lst is created. After that the user is prompted to enter the size of the list which determines how many elements user wants to add to the list. num holds the size input by user. After that print statement displays the line"Enter a list of numbers: ". Next the for loop takes the integers from user num times. Suppose user want to enter 3 as list size then loop will take 3 elements from user. int(input("")) in this statement integer type input is taken from user using input() method. lst.append(integers) statement is used to append these input integers into the list i.e. lst. print(indexOfSmallestElement(lst)) the statement calls the indexOfSmallestElement by passing lst to this method to return the index of the smallest element in the list of integers.
What is the difference between requirements and controls in the security process? Give examples of each.
Answer:
Security controls are those measures taken to prevent, identify, counteract, and reduce security risks to computer systems, whereas, Security Requirements are guidelines or frameworks that stipulates measures to ensure security control.
Explanation:
Security controls encompass all the proactive measures taken to prevent a breach of the computer system by attackers. Security requirements are those security principles that need to be attained by a system before it can be certified as safe to use.
Security controls are of three types namely, management, operational, and technical controls. Examples of technical controls are firewalls and user authentication systems. A statement like 'The system shall apply load balancing', is a security requirement with an emphasis on availability.
Makers of tablet computers continually work within narrow constraints on cost, power consumption, weight, and battery life. Describe what you feel would be the perfect tablet computer. How large would the screen be? Would you rather have a longer-lasting battery, even if it means having a heavier unit? How heavy would be too heavy? Would you rather have low cost or fast performance Should the battery be consumer-replaceable?
Answer:
In my opinion I would spend my money on a pc, tablets are of no use anymore besides having a larger screen, nowadays you either have a phone or a computer.

What will be the typical runtime of a tablet?The typical runtime of a tablet is between three and ten hours. More charge is typically needed for less expensive models than for more expensive tablets.
The typical runtime of a tablet is between three and ten hours. More charge is typically needed for less expensive models than for more expensive tablets. It might go a week or longer between charges if you only use the tablet once or twice each day.
Many people find that charging merely 80% is ineffective. Your phone won't function if you fully charge it and then use it in a single day. The 40-80% rule applies if, like me, your daily usage is limited to 25–50%.

Write a program to prompt the user for hours and rate per hour using input to compute gross pay. Pay the hourly rate for the hours up to 40 and 1.5 times the hourly rate for all hours worked above 40 hours. Use 45 hours and a rate of 10.50 per hour to test the program (the pay should be 498.75).
Answer:
Following is the program in the python language
hr = input("input hours:") #Read input by user
h1 = float(hr)
rate =input("Input Rate:") #Read RATE BY USER
r1 = float(rate) #CONVERT INTO FLOAT
if h1 <= 40: #check condition
t=h1 * r1
print (t) #DISPLAY
else :#else block
t1=(40 * r1) + (h1 -40) * r1 * 1.5
print('The pay is :')
print(t1)#DISPLAY
Output:
input hours:45
Input Rate:10.50
The pay is :
498.75
Explanation:
Following are the description of program
Read the value of hour in the "hr" variable and convert into the float value in the "h1" variable .Read the value of rate in the " rate" variable and convert into the float value in the "r1" variable .After that check the condition of hour if block if the hour is less then or equal to 40 then it multiplied h1 *t1 otherwise else block will be executed and print the value of pay .
