A group of computer scientists wants to create a fixed-length compression algorithm. The simplest way to achieve compression is to use a fixed-length code generator. The idea behind this type of code generator is to assign a fixed-length bit sequence to each symbol of the alphabet. As part of this group of computer scientists, your goal is to write a program to determine the alphabet used by the message to be compressed (set of different characters in the input message), and the frequency of each symbol in the alphabet, using conditionals, loops, and arrays.
Answer:
Here the code is given as follows,
Explanation:
OUTPUT:

In cell B13, create a formula without a function using absolute references that subtracts the values of cells B5 and
B7 from cell B6 and then multiples the result by cell B8. please help with excel!! I'm so lost
Answer:
The formula in Excel is:
=($B$6 - $B$5 - $B$7)* $B$8
Explanation:
Required
Use of absolute reference
To reference a cell using absolute reference, we have to include that $ sign. i.e. cell B5 will be written as: $B$5; B6 as $B$6; B7 as $B$7; and B8 as $B$8;
Having explained that, the formula in cell B13 is:

Question 6 Which of the following statements about datasets used in Machine Learning is NOT true? 1 point Testing data is data the model has never seen before and is used to evaluate how good the model is Training subset is the data used to train the algorithm Validation data subset is used to validate results and fine-tune the algorithm's parameters Training data is used to fine-tune algorithm’s parameters and evaluate how good the model is
Answer:
Training data is used to fine-tune the algorithm’s parameters and evaluate how good the model is
Explanation:
The statement about datasets used in Machine Learning that is NOT true is "Training data is used to fine-tune algorithm’s parameters and evaluate how good the model is."
This is based on the fact that a Training dataset is a process in which a dataset model is trained for corresponding it essentially to fit the parameters.
Also, Testing the dataset is a process of examining the performance of the dataset. This refers to hidden data for which predictions are determined.
And Validation of dataset is a process in which results are verified to perfect the algorithm's details or parameters
Suppose that in a 00-11 knapsack problem, the order of the items when sorted by increasing weight is the same as their order when sorted by decreasing value. Give an efficient algorithm to find an optimal solution to this variant of the knapsack problem, and argue that your algorithm is correct.
Answer:
Following are the response to the given question:
Explanation:
The glamorous objective is to examine the items (as being the most valuable and "cheapest" items are chosen) while no item is selectable - in other words, the loading can be reached.
Assume that such a strategy also isn't optimum, this is that there is the set of items not including one of the selfish strategy items (say, i-th item), but instead a heavy, less valuable item j, with j > i and is optimal.
As [tex]W_i < w_j[/tex], the i-th item may be substituted by the j-th item, as well as the overall load is still sustainable. Moreover, because [tex]v_i>v_j[/tex] and this strategy is better, our total profit has dropped. Contradiction.

Overview In this assignment, you will gain more practice with designing a program. Specifically, you will create pseudocode for a higher/lower game. This will give you practice designing a more complex program and allow you to see more of the benefits that designing before coding can offer. The higher/lower game will combine different programming constructs that you have been learning about, such as input and output, decision branching, and a loop. IT 140 Higher/Lower Game Sample Output Overview Maria has asked you to create a program that prompts the user to enter the lower bound and the upper hound. You have decided to write pseudocode to design the program before actually developing the code. When run, the program should ask the user to guess a number. If the number guessed is lower than the random number, the program should print out a message like "Nope, too low." if the number guessed is higher than the random number, print out a message like "Nope, too high." If the number guessed is the same as the random number, print out a message like "You got it!" Higher/Lower Game Description Your friend Maria has come to you and said that she has been playing the higher/lower game with her three-year-old daughter Bella. Maria tells Bella that she is thinking of a number between 1 and 10, and then Bella tries to guess the number. When Bella guesses a number, Maria tells her whether the number she is thinking of is higher or lower or if Bella guessed it. The game continues until Bella guesses the right number. As much as Maria likes playing the game with Bella, Bella is very excited to play the game all the time, Maria thought it would be great if you could create a program that allows Bella to play the game as much as she wants. Note: The output messages you include in your pseudocode may differ slightly from these samples. Sample Output Below is one sample output of the program, with the user input demonstrated by bold font. Prompt For this assignment, you will be designing pseudocode for a higher/lower game program. The higher/lower game program uses similar constructs to the game you will design and develop in Projects One and TWO. Welcome to the higher/lower game, Bella! Enter the lower bound: 10 Enter the upper bound: 30 Great, now guess a number between 10 and 30: 20 Nope, too low Guess another number: 25 Nope, too high Guess another number: 23 You got it! Below is another sample output of your program, with the user input demonstrated by bold font 1. Review the Higher/Lower Game Sample Output for more detailed examples of this game. As you read, consider the following questions: What are the different steps needed in this program? How can you break them down in a way that a computer can understand? What information would you need from the user at each point (inputs)? What information would you output to the user at each point? When might it be a good idea to use 'F' and "IF ELSE' statements? When might it be a good idea to use loop? 2. Create pseudocode that logically outlines each step of the game program so that it meets the following functionality: Prompts the user to input the lower bound and upper bound. Include input validation to ensure that the lower bound is less than the upper bound. - Generates a random number between the lower and upper bounds Prompts the user to input a guess between the lower and upper bounds. Include input validation to ensure that the user only enters values between the lower and upper bound. Prints an output statement based on the puessed number. Be sure to account for each of the following situations through the use of decision branching . What should the computer output if the user guesses a number that is too low? . What should the computer output if the user guesses a number that is too high? - What should the computer output if the user guesses the right number? Loops so that the game continues prompting the user for a new number until the user guesses the correct number. Welcome to the higher/lower game, Bella! Enter the lower bound: 10 Enter the upper bound: 5 The lower bound must be less than the upper bound. Enter the lower bound: 10 Enter the upper bound: 20 Great, now guess a number between 10 and 20: 25 Nope, too high Guess another number: 15 Nope, too low. Guess another number: 17 You got it! Sutrnil your completed pseudocode as a Word document of approximately 1 to 2 pages in length.
Answer:
Pseudocode
lower = upper = 0
while lower > upper
input lower
input upper
if lower > upper
print "Lower bound is greater than upper bound"
randNum = generate_a_random_number
print "Guess a number between",lower,"and",upper
input num
while num <> randNum

For each compound below, identify any polar covalent bonds and indicate the direction of the dipole moment using the symbols δ +and δ-.
(a) HBr
(b) HCI
(c) H2O
(d) CH40
Answer:
H-Br bond is polar, hydrogen is partly positive and bromine is partly negative
H-Cl bond is polar, hydrogen is partly positive and bromine is partly negative
O-H bond in water is polar, hydrogen is partly positive and oxygen is partly negative
C-O bond in CH40 is polar, carbon is partly positive and oxygen is partly negative
Explanation:
A molecule possess a dipole moment when there is a large difference in electro negativity between two bonding atoms in the molecule.
The presence of dipole moments introduces polarity to the molecule. In all the molecules listed in the answer, the shared electron pair of the bond is closer to the more electronegative atom causing it to be partially negative while the less electronegative atom in the bond is partially positive.

Discuss at least 1 Microsoft Windows security features that could protect data?
Answer:
Virus & threat protection.
Explanation:
Monitor threats to your device, run scans, and get updates to help detect the latest threats.
One Microsoft Windows security feature that can help protect data is BitLocker Drive Encryption.
BitLocker is a full-disk encryption feature available in certain editions of Microsoft Windows, such as Windows 10 Pro and Enterprise. It provides protection for data stored on the system's hard drives or other storage devices.
By encrypting the entire drive, BitLocker helps safeguard the data against unauthorized access or theft, even if the physical drive is removed from the device. It uses strong encryption algorithms to convert the data into an unreadable format, ensuring that only authorized users with the appropriate encryption key or password can access and decrypt the data.
BitLocker also provides additional security features, such as pre-boot authentication, which requires users to enter a password or use a USB key to unlock the drive before the operating system loads. This prevents unauthorized users from accessing the encrypted data, even if they have physical access to the device.
Overall, BitLocker Drive Encryption is a powerful security feature in Microsoft Windows that can effectively protect data by encrypting entire drives and adding layers of authentication and protection against unauthorized access.

Answer:
outline 3 computer system problem that could harm people and propose the way avoid the problem are :_
Computer Won't Start. A computer that suddenly shuts off or has difficulty starting up could have a failing power supply. Abnormally Functioning Operating System or Software. Slow Internet.Write a program Ticket.py that will allow the user to enter actual speed
limit, the speed limit at which the offender was travelling, and the number
of previous tickets that person has received. The application should
calculate and display how many miles over the speed limit the offender
was travelling, the cost of the speeding ticket, and court cost. Use $10.00
as the amount to be charged for each mile per hour over the speed limit.
The court cost should be $50.00
Answer:
Following are the code to the given question:
def speedlimit():#defining a method speedlimit
a= int(input("Enter the offender's speed in mph: "))#defining a variable for input value
lim = int(input("Enter the speed limit in mph: "))#defining a variable for input value
n = int(input("The number of previous tickets that person has received: "))#defining a variable for input value
if (lim >= 20) and (lim < 70):#defining if block to check speed is between 20 to 70
if a > lim:#use if to check lim value greater than a
print("Driver was going", a-lim, "mph over the limit.")#print calculated value with message
print("The cost of the speeding ticket $",10*(a-lim))#print calculated value with message
else:
print( "Driver was going at a legal speed.")#print message
else:
print('Invalid speed limit.')#print calculated value with message
print("Court cost $",(50 + n*20))#print calculated value with message
speedlimit()
Output:
Please find the attached file.
Explanation:
In this code, a method "speedlimit" is declared that defines three variables that are "a, lim, and n" in which we input value from the user-end.
Inside the method, a nested conditional statement is used that checks the speed value is between 20 to 70 if it is true it will go to the next condition in which it checks lim value greater than a. It will use a print message that will print the calculated value with the message.
