The example of code that have all the added feature of the print_menu() function and preliminary functions for each of the listed menu items is given in the image attached.
What is the program about?The menu offers file processing, unit selection, room filter editing, summary statistics display, temperature display by date and time, temperature histogram display, and program ending.
So one need to write a print_menu() function to display the menu options. Create stub functions for each menu option: new_file, choose_units, change_filter, print_summary_statistics, print_temp_by_day_time, print_histogram, and a graceful exit function. They should have a print statement instead of a pass statement for now. Stub functions have expected signatures but incomplete implementations, allowing testing before full implementation.

Building our menu
The next step in our project is to build a menu and the code to support it. The menu provides the interface that a user will use to interact with the program.
This assignment will give us practice using loops and conditionals.
We are building on the previous assignment. So start with Lab Assignment 2 and add your new code.
In this Lab Assignment you are going to:
• Create a new file named lab_assignment 3.py.
·
Copy your code from Lab Assignment 2 and paste it into you new file
• Add information to update the docstring to reflect Lab Assignment 3
• Add the new code you are writing to support the requirements for Lab Assignment 3
• Delete the main() the code used in lab_assignment 2 and write a new main() function to generate the required output (the Unit Test, for Lab Assignment 3
Write a function named print_menu()
print_menu() that takes no arguments and returns nothing. Its whole job is to print this menu:
Main Menu
1
2
Process a new data file
- Choose units
-
Edit room filter
4 - Show summary statistics
34567
5 - Show temperature by date and time
7
Show histogram of temperatures Quit
Incidentally, for the rest of the course, we will work on implementing all of the items referenced by the menu.
We are first going to write stub functions which will later be completed. A stub is a function that has the expected signature (i.e. name of the function and parameters), but an incomplete implementation. A stub function is used as a placeholder and so that the code that calls the function can be tested before the called function is fully written.
Next, we need stub functions for the following
Each line below gives you the function signature (name of the function and it's parameters) of each function that you will create in the assignment
1. new_file(dataset) will be called when the user chooses item one.
2. choose_units() will be called when the user chooses item two.
3. change_filter(sensor_list, active_sensors) will be called when the user chooses item three.
4. print_summary_statistics(dataset, active_sensors) will be called when the user chooses item four.
5. print_temp_by_day_time(dataset, active_sensors) will be called when the user chooses item five.
6. print_histogram(dataset, active_sensors) will be called when the user chooses item six. This is an optional no- credit project.
7. And what about item seven? The program should exit gracefully.
These functions do not have any functionality yet. They will initially be stub functions, later you will add the code required for the application. Instead of using the pass statement, though, we will use a print statement for each function so we know that it has been called. Our new_file() function, for example, will look like this:
def new_file(dataset):
"I II II
Open a new file
иии
print("New File Function Called")
Since you do not know the purpose of each of these functions yet, you can just a generic docstring for now.

Attendees who are also board members receive a discount off the registration fees. The discount amount varies based on the type of event. In cell J11 enter a formula that will return the discount amount if the registrant is a board member and return a blank value ("") if they are not.
Use a VLOOKUP function to retrieve the EventType from the EventDetails named range.
Use an INDEX function, with the cell range A5:B8 on the ClientRegistration worksheet as the array and the result of the VLOOKUP as the lookup_value for the MATCH function needed for the row_num argument.
Use an IF function so that the discount only applies to board members and all others will display as a blank ("")
Format the result as Percentage with 0 decimal places.
Copy the formula down through J34.
Answers
Initially, the formula verifies whether or not the attendee is a board member using the COUNTIF function.
How to explain the informationThis counts how many times their name appears in the "BoardMembers" named range. If the count exceeds zero, then the VLOOKUP operator within the formula retrieves the EventType of the current attendee from the "EventDetails" named range.
Then, via usage of the MATCH and INDEX functions, the formula identifies the matching row number in the registration worksheet for the retrieved EventType. The identified row number will be positioned as an argument (row_num) for the INDEX formula. As it executes, the INDEX formula can retrieve the relevant discount percentage value from column B.
Finally, by executing multiplication between the extracted discount percentage and 0.1 (as this expresses the respective reduction), the newly achieved outcome -a properly formatted percentage with no decimal points is returned by the original formula.

Explanation:
In the main program, we first set the value of number to 5 using mov al,5 and mov [number],al. Then, we call the Encode function to add the character '0' to number. Next, we call the Print function to print the value of number on the console. After that, we call the Decode function to remove the character '0' from number. Then, we increment the value of number by 1 using inc byte [number]. Finally, we call the Encode function again to add the character '0' to number, and then call the Print function to print the updated value of number on the console.
The Encode function takes the variable address as an argument in ECX, and adds the character '0' to the variable using ADD BYTE [ECX],'0'.
The Decode function also takes the variable address as an argument in ECX, and subtracts the character '0' from the variable using SUB BYTE [ECX],'0'.
The Print function uses the mov ecx,number instruction to load the address of number into ECX, and then prints the byte value at that address using the int 80h instruction.

Doing the right is not relative to the situation but is based on the ethical standards and personal responsibility. Discuss using Normative ethics
Answers
In the context of the statement "Doing the right thing is not relative to the situation but is based on ethical standards and personal responsibility," normative ethics would argue that there are certain ethical principles that apply universally, regardless of the situation. These principles include concepts such as justice, fairness, honesty, and respect for others.
For instance, if a person is faced with a situation where they have the option to lie or tell the truth, normative ethics would suggest that telling the truth is the right thing to do, regardless of the situation. This is because honesty is a universal ethical principle that applies in all situations, and it is based on the value of respecting others and their right to the truth.
Personal responsibility is also a key aspect of normative ethics. It suggests that individuals have a duty to act in ways that are consistent with ethical principles, and they should be held accountable for their actions. This means that people should take responsibility for their behavior, rather than blaming external factors such as the situation, culture, or social norms.
In summary, normative ethics would argue that doing the right thing is not relative to the situation, but rather it is based on universal ethical principles and personal responsibility. This means that individuals have a moral obligation to act in ways that are consistent with ethical principles, regardless of the situation, and they should take responsibility for their actions.

What is the difference between multiprogramming and multicore, and how do they relate to each other?
Answers
Answer: The primary difference between multicore and multiprocessor is that a multicore operates a single CPU, while a multiprocessor has multiple CPUs. In a simplified way, if you want a computer to run a single program faster, that is a job for a multicore processor.
Explanation:
Multiprocessing is a system that has two or more than one processors. In this, CPUs are added for increasing the computing speed of the system. Because of Multiprocessing, there are many processes that are executed simultaneously. Multiprocessing is further classified into two categories: Symmetric Multiprocessing, Asymmetric Multiprocessing.
Multi-programming is more than one process running at a time, it increases CPU utilization by organizing jobs (code and data) so that the CPU always has one to execute. The motive is to keep multiple jobs in the main memory. If one job gets occupied with Input/output, the CPU can be assigned to other jobs.
Trace coding below
j = 2
k = 5
n = 9
while j < k
m = 6
while m < n
output "Goodbye"
m = m + 1
endwhile
j = j + 1
endwhile
Answers
Answer:
Explanation:
The output of the code will be "Goodbye" printed 6 times for each iteration of the outer loop.
Explanation:
j is initialized to 2, k is initialized to 5, and n is initialized to 9. The outer loop will run as long as j is less than k, so it will run for 3 iterations.
In the first iteration, j is 2, so the inner loop starts with m being set to 6. The inner loop will run as long as m is less than n, so it will run for 3 iterations. During each iteration, the string "Goodbye" will be output.
In the second iteration of the outer loop, j is 3 and the inner loop will run again for 3 iterations, outputting "Goodbye" each time.
In the third and final iteration of the outer loop, j is 4 and the inner loop will run for 3 more iterations, outputting "Goodbye" each time.
After the third iteration of the outer loop, the program will terminate.

Discuss the importance of the topic of your choice to a fingerprint case investigation.
Answers
Explanation:
One important topic in fingerprint analysis that is crucial to a fingerprint case investigation is the concept of individualization. Individualization refers to the process of comparing a latent fingerprint found at a crime scene with a known fingerprint of a suspect, and determining whether they match or not. This process is critical to forensic science because it forms the basis for establishing the identity of a perpetrator.
In a fingerprint case investigation, individualization plays a critical role in connecting a suspect to a crime scene. When a latent fingerprint is found at a crime scene, investigators will collect and analyze it to determine whether it matches a known fingerprint of a suspect. If a match is found, it can be used as evidence in court to establish the suspect's presence at the crime scene, and thus their involvement in the crime.
However, it is important to note that individualization is not foolproof. There is always a small chance that two fingerprints may have similar ridge characteristics, leading to a false positive identification. Therefore, it is important for fingerprint analysts to exercise caution and adhere to strict standards when conducting individualization analyses.
Overall, individualization is a crucial topic in fingerprint analysis for any fingerprint case investigation. By properly analyzing the unique characteristics of individual fingerprints, investigators can connect suspects to crime scenes and ultimately bring justice to victims and their families.

Answers
Answer:In order to modernize our coffee shop and improve our efficiency, we need to use a variety of input and output devices. Input devices are used to enter data into the computer system, while output devices are used to display or print information from the computer system. The types of data we will regard as input include customer orders, employee time sheets, inventory levels, and financial transactions. The information we will regard as output includes receipts, order confirmations, inventory reports, and financial statements.
To enter data and produce information, we will use a variety of computers, mobile devices, and other technologies. For example, we will use desktop computers with high processing power and large memory storage to keep track of inventory and financial transactions. We will also use mobile devices such as smartphones and tablets to take orders and process payments. These devices will need to be equipped with barcode scanners and credit card readers to streamline the payment process.
In addition, we will use specialized software to manage our business operations. For example, we will use point-of-sale (POS) software to take orders, process payments, and manage inventory. We will also use accounting software to keep track of our financial transactions and generate financial statements.
Based on my own experiences and user reviews, I recommend using high-quality devices that are reliable and easy to use. For example, we should use computers with fast processors and large memory storage to ensure that they can handle our business operations without slowing down. We should also use mobile devices with long battery life and durable construction to ensure that they can withstand heavy use in a fast-paced environment.
Overall, by using a variety of input and output devices, specialized software, and high-quality devices, we can improve our efficiency and better serve our customers.
Explanation:
Write a program that lists all ways people can line up for a photo (all permutations of a list of Strings). The program will read a list of one word names (until -1), and use a recursive method to create and output all possible orderings of those names separated by a comma, one ordering per line. When the input is: Julia Lucas Mia -1 then the output is (must match the below ordering): Julia, Lucas, Mia Julia, Mia, Lucas Lucas, Julia, Mia Lucas, Mia, Julia Mia, Julia, Lucas Mia, Lucas, Julia in java code
Answers
Answer:
public class PhotoLineup {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
List<String> names = new ArrayList<>();
String name;
do {
name = input.next();
if (!name.equals("-1")) {
names.add(name);
}
} while (!name.equals("-1"));
Collections.sort(names); // sort the names alphabetically
List<String> chosen = new ArrayList<>();
List<List<String>> permutations = new ArrayList<>();
generatePermutations(names, chosen, permutations);
for (List<String> permutation : permutations) {
System.out.println(String.join(", ", permutation));
}
}
private static void generatePermutations(List<String> names, List<String> chosen, List<List<String>> permutations) {
if (names.isEmpty()) { // base case
permutations.add(new ArrayList<>(chosen));
} else {
for (int i = 0; i < names.size(); i++) {
String name = names.get(i);
chosen.add(name);
names.remove(i);
generatePermutations(names, chosen, permutations);
names.add(i, name);
chosen.remove(chosen.size() - 1);
}
}
}
}
Explanation:
The program reads the names from the user input and stores them in an ArrayList. It then sorts the names alphabetically, since we want to output them in alphabetical order as well. It initializes two empty lists: chosen (to keep track of the names chosen so far in each permutation) and permutations (to store all the permutations).
The program then calls the generatePermutations method with the names, chosen, and permutations lists. This method uses a recursive algorithm to generate all possible permutations of the names. It does this by trying each name in turn as the next one in the permutation, and then recursively generating all the permutations of the remaining names. When it reaches a base case (where there are no more names left to choose), it adds the current permutation to the permutations list.
Finally, the program outputs each permutation on a separate line by joining the names with commas using the String.join method.

Insertion sort in java code. I need a modified code of the code given, output need to print exact. Make sure to give explanation and provide output. My output is printing the wrong comparison. My output is printing a comparisons: 4 and comparsions: 9, What I need is a java code thats output to print a comparisons: 7.
The program has four steps:
Read the size of an integer array, followed by the elements of the array (no duplicates).
Output the array.
Perform an insertion sort on the array.
Output the number of comparisons and swaps performed.
main() performs steps 1 and 2.
Implement step 3 based on the insertion sort algorithm in the book. Modify insertionSort() to:
Count the number of comparisons performed.
Count the number of swaps performed.
Output the array during each iteration of the outside loop.
Complete main() to perform step 4, according to the format shown in the example below.
Hints: In order to count comparisons and swaps, modify the while loop in insertionSort(). Use static variables for comparisons and swaps.
The program provides three helper methods:
// Read and return an array of integers.
// The first integer read is number of integers that follow.
int[] readNums()
// Print the numbers in the array, separated by spaces
// (No space or newline before the first number or after the last.)
void printNums(int[] nums)
// Exchange nums[j] and nums[k].
void swap(int[] nums, int j, int k)
When the input is:
6 3 2 1 5 9 8
the output is:
3 2 1 5 9 8
2 3 1 5 9 8
1 2 3 5 9 8
1 2 3 5 9 8
1 2 3 5 9 8
1 2 3 5 8 9
comparisons: 7
swaps: 4

Explanation:
The code you provided is implementing an insertion sort algorithm on an integer array. The program reads the size of the integer array and its elements, then outputs the array before sorting it. The insertionSort() method performs the sorting and counts the number of comparisons and swaps performed during the sorting process. The main() method calls the insertionSort() method and outputs the sorted array and the number of comparisons and swaps made during the sorting process.

He has asked for projected sales figures broken down
by season.
Create one formula that can be copied down and then across.
Answers
Below is an example of a formula that you can use to calculate projected sales figures broken down by season, which can be copied down and across:
What is the formula?Assuming that the seasons are in cells B1:E1 (Summer, Fall, Winter, Spring) and the projected sales data is in cells A2:A6 (Sporting Goods, Electronics, Housewares, Toys, Clothing), you can use the following formula in cell B2:
swift
=A$2 * IF($B$1="Summer", 0.13, IF($B$1="Fall", 0.25, IF($B$1="Winter", 0.30, IF($B$1="Spring", 0.32, 0))))
This formula multiplies the projected sales amount (cell A2) by the corresponding percentage for each season (0.13 for Summer, 0.25 for Fall, 0.30 for Winter, and 0.32 for Spring), based on the value in cell B1. The dollar signs ($) are used to lock the references for cell A2 and the column B, so that the formula can be copied across and down to calculate projected sales for other seasons and product categories.
You can copy this formula down for the remaining product categories (cells B3:B6) and across for the remaining seasons (cells C2:E6) to calculate the projected sales figures broken down by season for all the product categories.

a car has a fuel capacity of 12 gallon and a fuel consumption of 45miles per gallon.gas cost 120.56a gallon.how far can the travel on 916.64 worth of petrol?
Answers
Where the fuel capacity above is given, the car can travel 342 miles on $916.64 worth of petrol.
What is the explanation for the above response?
To solve this problem, we need to use the formula:
distance = fuel capacity x fuel consumption
First, we need to calculate the amount of fuel that can be purchased with $916.64:
$916.64 ÷ $120.56/gallon = 7.6 gallons
Now, we can use the fuel consumption rate to find out how far the car can travel on this amount of fuel:
distance = 7.6 gallons x 45 miles/gallon = 342 miles
Therefore, the car can travel 342 miles on $916.64 worth of petrol.
