Assume you have a byte-addressable machine that uses 32-bit word (integers are 32-bit) and you are storing the following information: the string Inventory followed by a value (569)10 followed by another string Price followed by a value (49.75)10. Also, assume that floating point numbers are stored as single-precision IEEE 754 with 127 excess. a) Show (as hex numbers with word boundary) how this is stored on a big-endian machine. b) Show (as hex numbers with word boundary) how this is stored on a little-endian machine.
Final answer:
The question involves displaying how a string and numerical data will be stored in hexadecimal format in memory on a machine with both big-endian and little-endian architectures. The storage pattern involves converting ASCII strings and numbers into hexadecimal format and then storing them sequentially in memory according to the endianess. Exact hexadecimal values would require ASCII and IEEE 754 format conversions.
Explanation:
The given question involves storing textual and numerical data on a byte-addressable machine that uses 32-bit integers and single-precision floating-point format, according to the IEEE 754 standard. The data to be stored includes a string 'Inventory', a decimal integer value (569)10, a string 'Price', and a decimal floating-point number (49.75)10. We are asked to show how this information would be stored in both big-endian and little-endian representation. Firstly, we need to translate the ASCII strings and numerical values into hexadecimal, suitable for storage in memory:
The string 'Inventory' is broken into 32-bit words and converted to hexadecimal.
The integer value 569 is represented in hexadecimal as 0x00000239.
The string 'Price' is similarly broken into 32-bit words and converted to hexadecimal.
The floating-point number 49.75 is converted into IEEE 754 single-precision format and represented in hexadecimal.
For big-endian representation, the most significant byte (MSB) is stored at the lowest memory address:
Each character of 'Inventory' and 'Price' is represented by its ASCII hexadecimal value and stored in sequential memory addresses, starting with the MSB.
The integer and floating-point numbers are stored with their MSB first in the 32-bit word boundary.
For little-endian representation, the least significant byte (LSB) is stored at the lowest memory address:
Each character of 'Inventory' and 'Price' is represented in reverse order compared to big-endian.
The integer and floating-point numbers are also reversed, with the LSB first.
The exact hexadecimal values in memory would depend on the binary representations of the strings and the specifics of the IEEE 754 conversion process for the number 49.75.
Writing a modular program in visual c++. I am new to this and not sure what I am missing. I am getting the following error:

Here are the instructions and code:
Writing a Modular Program in C++
In this lab, you add the input and output statements to a partially completed C++ program. When completed, the user should be able to enter a year, a month, and a day. The program then determines if the date is valid. Valid years are those that are greater than 0, valid months include the values 1 through 12, and valid days include the values 1 through 31.
Notice that variables have been declared for you.
Write the simulated housekeeping() function that contains the prompts and input statements to retrieve a year, a month, and a day from the user.
Include the output statements in the simulated endOfJob() function. The format of the output is as follows:
month/day/year is a valid date.
or
month/day/year is an invalid date.
Execute the program entering the following date: month = 5, day = 32, year = 2014. Record the output of this program.
Execute the program entering the following date: month = 9, day = 21, year = 2002. Record the output of this program.
Answer:
#include <iostream>
bool validateDate(int, int, int);
using namespace std;
int main()
{
int year;
int month;
int day;
const int MIN_YEAR = 0, MIN_MONTH = 1, MAX_MONTH = 12, MIN_DAY = 1, MAX_DAY = 31;
bool validDate = true;
cout<<"Enter the year"<<endl;
cin>>year;
cout<<"Enter the month"<<endl;
cin>>month;
cout<<"Enter the day"<<endl;
cin>>day;
if(year <= MIN_YEAR) // invalid year
validDate = false;
else if (month < MIN_MONTH || month > MAX_MONTH) // invalid month
validDate = false;
else if (day < MIN_DAY || day > MAX_DAY) // invalid day
validDate = false;
if(validDate == true)
{
// Output statement
cout<<month<<"/"<<day<<"/"<<year<<"is a valid date"<<endl;
}
else
{
// Output statement
cout<<month<<"/"<<day<<"/"<<year<<" is an invalid date"<<endl;
}
}
Explanation:
Declare variables and take the date as input from user .Inside the main function, check if year is valid using the conditional statements.Check if date is valid and then output that accordingly.To fix the 'else' without a previous 'if' error in your code, you need to ensure that you have an 'if' statement before the 'else' keyword. Update your code to include conditional statements to check the validity of the entered date. Once you make the necessary changes, recompile and run your code to see the desired output.
Explanation:The error you are encountering, 'else' without a previous 'if', typically occurs when there is a missing or unmatched 'if' statement before the 'else' keyword in your code. In the given instructions and code, you need to add conditional statements to check the validity of the entered date. Here is an example of how you can modify your code:
#include <iostream>This modified code checks if the entered year, month, and day are within the valid ranges. If the date is valid, it prints a message saying so; otherwise, it prints a message indicating an invalid date. Make sure to recompile and run the updated code to see the desired output. This should resolve the error you were encountering.

Suppose a meteorology station records the temperature and humidity at each hour of every day and stores the data for the past ten days including four numbers that indicate the day, hour, temperature, and humidity. Write a Java program that calculates the average daily temperature and humidity for the 10 days. The first index of data represents 10 days, the second index represents 24 hours, and the third index represents temperature and humidity, respectively. You may randomly select the values of temperature/humidity.
Answer:
The complete program is given below with step by step comments for explanation.
Explanation:
So we need to write a program that can calculate the average daily temperature and humidity. We can create a class named Weather_Station to do the job.
public class Weather_Station
{
public static void main(String[] args)
{
// we are told that the data is for 10 days and 24 hours so they are fixed and cannot be changed
final int Days = 10;
final int Hours = 24;
// Then we define a three-dimensional array named station for storing days, hours and temperature/humidity
double[][][] station = new double[Days][Hours][2];
// Then we read input from a file
Scanner input = new Scanner(System.in);
// Since there is a lot of data, using a loop to extract the data would be a good idea so we run a loop for 10*24 times to get the day, hour, temperature and humidity values.
for (int k = 0; k < Days*Hours; k++)
{
int day = input.nextInt();
int hour = input.nextInt();
double temp = input.nextDouble();
double humidity = input.nextDouble();
station[day - 1][hour - 1][0] = temp;
station[day - 1][hour - 1][1] = humidity;
}
// Since we want to get the average temperature and humidity of each day for 10 days so we run a loop for days times (thats 10)
for (int i = 0; i < Days; i++)
{
double Total_temp = 0;
double Total_humidity = 0;
// Then we run another loop to add up all the temperatures and humidity values for each hour in a day and store them in Total_temp and Total_humidity respectively.
for (int j = 0; j < Hours; j++)
{
Total_temp += station[i][j][0];
Total_humidity += station[i][j][1];
}
}
// The average is simply the total number of temperature values divided by the number of hours, same goes for humidity.
double Avg_temp=Total_temp / Hours;
double Avg_humidity=Total_humidity / Hours;
// Then we print the values of any day's average temperature and humidity
System.out.println("For the Day of " + i + "Average Temperature is " + Avg_temp);
System.out.println("For the Day of " + i + "Average Humidity is " + Avg_humidity);
}
}
Final answer:
This response provides a Java program that simulates the collection of temperature and humidity data from a meteorology station and calculates the average daily temperature and humidity over 10 days. It makes use of a 3-dimensional array to store and process the hourly data for each day.
Explanation:
Java Program to Calculate Average Daily Temperature and Humidity
In order to calculate the average daily temperature and humidity using a Java program, we will first simulate the data collection from a meteorology station, which records temperature and humidity hourly for 10 days. The program will iterate through this data to calculate the averages.
The following Java program does just that, and it can be expanded or adapted for different datasets or time periods:
public class WeatherStation {
public static void main(String[] args) {
// Randomly generate data for temperature and humidity
int[][][] data = new int[10][24][2];
for (int day = 0; day < data.length; day++) {
for (int hour = 0; hour < data[day].length; hour++) {
data[day][hour][0] = (int)(Math.random() * 30) + 10; // Temperature
data[day][hour][1] = (int)(Math.random() * 100); // Humidity
}
}
// Calculate average temperature and humidity for each day
for (int day = 0; day < data.length; day++) {
double dailyTempTotal = 0, dailyHumidityTotal = 0;
for (int hour = 0; hour < data[day].length; hour++) {
dailyTempTotal += data[day][hour][0];
dailyHumidityTotal += data[day][hour][1];
}
double dailyTempAverage = dailyTempTotal / data[day].length;
double dailyHumidityAverage = dailyHumidityTotal / data[day].length;
System.out.println("Day " + (day + 1) + ": Average Temperature = " + dailyTempAverage
+ ", Average Humidity = " + dailyHumidityAverage);
}
}
}
This simple program creates a 3-dimensional array to store 10 days of hourly temperature and humidity readings, then calculates the average values for each day, providing crucial insights into the climate and environmental conditions of the region.

The _________ is fundamentally a client/server application running over the Internet and TCP/IP intranets.
Answer:
World Wide Web
Explanation:
The world wide web shortened as www is a convenient way of refering to the internet. The Internet is a massive (globally) inter connection of computers which are communicating with each other and sharing information. The architecture of the word wide web (i.e the internet) is analogous to the client sever computer network architecture, because in a client/server network a powerful computer is designated as server and several work stations (clients) are connected to this server, the clients request and retreive information stored in the servers. This is comparable to the www Whereby information stored in multiple server locations globally are requested and retrieved using the uniform resource locator (URL).
Suppose that someone suggests the following way to confirm that the two of you are both in possession of the same secret key. You create a random bit string the length of the key, XOR it with the key, and send the result over the channel. Your partner XORs the incoming block with the key (which should be the same as your key) and sends it back. You check and if what you receive is your original random string, you have verified that your partner has the same secret key, yet neither of you has ever transmitted the key. Is there a flaw in this scheme?
*Please dont only give me the answer but also explain WHY, maybe use "//" or "*" Important homework assignment
Answer:
The given question is discussed below in detail.
OR and XOR are used to make the concepts clear instead of the signs "//" and "*" .
First of all the senders and users key will be analyzed.
I hope it will help you!
Explanation:
The true statement is that the scheme is prone to attacks.
From the question, we understand that:
The result when the string and its length are XOR is sent to the partnerThe partner decodes the message and sends it backThe above highlight shows a complete communication, where:
You send K XOR R to your partnerYour partner returns R back to youHowever, there is a flaw in the scheme
The flaw in the scheme is that, the scheme is prone to attacks.
Where the values that are being communicated are visible to the attacker;
The attacker can then make several computations to alter the code that is being sent

Discuss what technologies you might see in use at an enterprise. For example, where would you most likely see fiber-optic Ethernet technologies? Or where might wireless technologies be deployed?
There are various connectivity technologies that we use to connect. They are Ethernet, Internet (Wireless Connection), Bluetooth, Wi-Fi and Cellular.
Explanation:
Ethernet is the direct connection among the devices that are located close to each other in a building. This is used for small scale enterprises.Wi-Fi lets wireless connections among multiple devices without any physical connection. And it is most extensively used in most of the corporate companies.Bluetooth is used to transfer the data from one device to the other when they are near.Cellular is used to connect people across the globe. And it is used widely in every enterprises.Final answer:
In an enterprise, fiber-optic Ethernet is used for its high bandwidth and long-distance capabilities, typically in the network backbone, while wireless technologies like Wi-Fi are deployed for their convenience and mobility in offices and meeting spaces. The use and impact of technology can vary across different contexts, and strategic decisions must be made when developing IT infrastructures to ensure efficiency and security.
Explanation:
In an enterprise, you might see a range of technologies in use, each tailored to specific needs and applications. Fiber-optic Ethernet technologies, for instance, are often found in the backbone of an enterprise’s network infrastructure where high bandwidth and long-distance communication are essential.
They might be used to connect data centers, mainframes, or to handle high-speed internet connections for the entire organization.
Wireless technologies, on the other hand, are typically deployed in areas where mobility is important or where it is impractical to run physical cabling.
This includes offices for Wi-Fi connections to laptops and smartphones, warehouses for barcode scanning devices, and meetings or conference rooms to facilitate presentations and collaborative work without the need for physical connections.
Wi-Fi is an example of a wireless service that has become indispensable in both professional and personal contexts, offering convenience and mobility.
When considering the integration of technology, it's important to assess the impact it has on communication across various contexts, such as academic, professional, and personal.

TV stations in the U.S. normally broadcast horizontally-polarized signals. Is this TV antenna mounted correctly, or should it be rotated?
It would be best to start positioning the antenna horizontally because the majority of TV transmitters are horizontally polarized. Antennas from One For All can pick up both horizontal and vertical signals.
What TV networks horizontally polarized programming?The most used antennas for television broadcasting emit signals that are horizontally polarized. In other words, the TV signal's plane is perpendicular to the earth's surface.
Aside from this, however, evidence suggests that using horizontal polarization at UHF gives benefits due to the higher directivity achievable at the receiving antennas, which lessens the impact of reflected waves, especially in urban areas.
Therefore, Outdoor TV antennae are placed horizontally rather than vertically because of this.
Learn more about polarized signals here:
https://brainly.com/question/14428334
#SPJ5
A TV antenna should be oriented horizontally for optimal reception of horizontally-polarized signals. Aligning a straight wire antenna or a loop antenna correctly ensures the strongest possible reception. Short wave antennas have a different orientation to utilize the ionosphere for long-distance signal transmission.
For optimal reception of horizontally-polarized signals, a TV antenna should be oriented horizontally. This alignment maximizes the pickup of the electric component of the electromagnetic wave, which is crucial for a clear signal. Conversely, if signals are broadcast using a vertical transmitter antenna, a straight wire antenna should be vertical to best receive the radio waves. This is essential because the strongest signal radiates perpendicularly to the antenna, ensuring equal signal distribution in all horizontal directions. A loop antenna should be aligned so that its plane is perpendicular to the direction of the incoming signal for the best reception. This plane orientation allows the loop antenna to maximize the induction of current by the electromagnetic waves, enhancing the received signal's strength.
In the context of signal reception at long distances, short wave antennas may be oriented horizontally so the signal can bounce off the ionosphere and travel a greater distance back to Earth. For TV signals, the video component is usually transmitted as amplitude modulation (AM), while the audio is frequency modulation (FM). It's important to note that these are characteristics of over-the-air broadcasting using traditional rooftop antennas, as opposed to satellite dishes or cable systems, which operate at significantly higher frequencies and use different technologies such as high-definition (HD) formats.

File Sales.java contains a Java program that prompts for and reads in the sales for each of 5 salespeople in a company. It then prints out the id and amount of sales for each salesperson and the total sales. Study the code, then compile and run the program to see how it works. Now modify the program as follows:
1. Compute and print the average sale. (You can compute this directly from the total; no loop is necessary.)
2. Find and print the maximum sale. Print both the id of the salesperson with the max sale and the amount of the sale, e.g., "Salesperson 3 had the highest sale with $4500." Note that you don’t need another loop for this; you can do it in the same loop where the values are read and the sum is computed.
3. Do the same for the minimum sale.
4. After the list, sum, average, max and min have been printed, ask the user to enter a value. Then print the id of each salesperson who exceeded that amount, and the amount of their sales. Also, print the total number of salespeople whose sales exceeded the value entered.
5. The salespeople are objecting to having an id of 0—no one wants that designation. Modify your program so that the ids run from 1-5 instead of 0-4. Do not modify the array—just make the information for salesperson 1 reside in array location 0, and so on.
6. Instead of always reading in 5 sales amounts, at the beginning ask the user for the number of salespeople and then create an array that is just the right size. The program can then proceed as before.

Explanation:
- Ask the user for the number of salesperson
- According to entered number, create an array called sales to hold sale number for each person
- In the first for loop, assign the given sales numbers
- In the second for loop, print all the sales people with sales, calculate the total sales. Also, find the minimum and maximum sales numbers with associated individuals.
- Print total, average, highest, and lowest sales.
- Ask user enter an amount
- In the third for loop, find the sales people who exceeded this amount.
- Print number of sales people who exceeded the amount.
This detailed explanation modifies Sales.java to include computing and printing the average, maximum, and minimum sales, and then prompts the user for a threshold to find salespeople exceeding it.
To modify the Sales.java program as per the requirements, start by reading the sales data and modify it according to the task.
Compute and print the average sale. This can be achieved by computing the sum of sales and then dividing by the number of salespeople.Find and print the maximum sale. While reading sales, keep track of the maximum sale and associated salesperson ID.Do the same for the minimum sale by tracking the minimum sale and its corresponding ID in the same loop.After computing the total, average, max, and min, prompt the user to enter a value and print the salespeople who exceeded this value along with the number of salespeople who did.Modify salesperson IDs to start from 1 instead of 0 while still using array indices starting from 0.Ask the user for the number of salespeople at the beginning and dynamically create an array of that size.Here is an example implementation:
import java.util.Scanner;
public class Sales {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
System.out.print("Enter the number of salespeople: ");
int numSalespeople = scan.nextInt();
int[] sales = new int[numSalespeople];
int sum = 0, maxSale = Integer.MIN_VALUE, minSale = Integer.MAX_VALUE;
int maxId = -1, minId = -1;
for (int i = 0; i < numofSalespeople; i++) {
System.out.print("Put sales for the salesperson " + (i + 1) + ": ");
sales[i] = scan.nextInt();
sum += sales[i];
if (sales[i] > maxSale) {
maxSale = sales[i];
maxId = i + 1;
}
if (sales[i] < minSale) {
minSale = sales[i];
minId = i + 1;
}
}
double average = (double) sum / numofSalespeople;
System.out.println("\nSalesperson" + " Sales");
System.out.println("------------------");
for (int i = 0; i < numofSalespeople; i++) {
System.out.println(" " + (i + 1) + " " + sales[i]);
}
System.out.println("\nTotal sales: " + sum);
System.out.println("Average sales: " + average);
System.out.println("Salesperson " + maxId + " had the highest sale with $" + maxSale);
System.out.println("Salesperson " + minId + " had the lowest sale with $" + minSale);
System.out.print("\nEnter a sales amount to compare: ");
int threshold = scan.nextInt();
int count = 0;
for (int i = 0; i < numofSalespeople; i++) {
if (sales[i] > threshold) {
System.out.println("Salesperson " + (i + 1) + " exceeded with sales of $" + sales[i]);
count++;
}
}
System.out.println("Total salespeople who surpass the amount: " + count);
}
}
Write three statements to print the first three elements of array runTimes. Follow each statement with a newline. Ex: If runTime = {800, 775, 790, 805, 808},print: 800 775 790import java.util.Scanner;public class PrintRunTimes {public static void main (String [] args) {int[] runTimes = new int[5];// Populate arrayrunTimes[0] = 800;runTimes[1] = 775;runTimes[2] = 790;runTimes[3] = 805;runTimes[4] = 808;/* Your solution goes here */return;}}
Answer:
Following are the code in the Java Programming Language.
//print first element of the array
System.out.println(runTimes[0]);
//Print second element of the array
System.out.println(runTimes[1]);
//print third element of the array
System.out.println(runTimes[2]);
Explanation:
Following are the description of the Program:
In the above program, There is the integer type array variable that is 'runTimes' and its index value is 5. Then, initialize values in the array one by one which means firstly, they insert in index 0, then in index 1, and so on. Finally, we have to print the first three elements of the array. So, we set the System.out.println() function three times to print array by passing array name and first three index value with it.
Print statements are used to display statements and expressions in a program.
The three print statements are:
System.out.println(arrayrunTimes[0]);System.out.println(arrayrunTimes[1]);System.out.println(arrayrunTimes[2]);The above statements are straightforward; however, we need to take not of the following highlights.
The question says, the print statement should print a new line, after printing each array element.
This can be achieved using System.out.println() or System.out.print('\n').
In this program, we used the former.
Also, array elements start its indices from 0.
This means that, the first element of the array is at index 0, the second is at index 1, and so on.

Janice is the sole owner of Catbird11 Joel is the sole shareholder of Manatee Corporation, a C corporation. Because Manatee's sales have increased igni cantl over the last several years, Joel has determined that the corporation needs a new distribution warehouse. Joel has asked your advice as to whether (1) Manatee should purchase the warehouse or (2) he should pt1rchase the warehot1se and lease it to Manatee. What relevant tax issues w ill you discuss with Joel?
Answer:
Answer explained below
Explanation:
Joel is the sole shareholder of Manatee Corp. C Corporation has separate legal identity and limited liability for the owner but the double taxation is its demerit as its revenue is taxed at the company level and again as shareholder dividends.
Therefore Joel should purchase the warehouse and lease it to Manatee to take the tax advantage and reduce his overall tax liability. Leasing assets to the corporation is legal also and corporation will pay rent to the owner and owner has to show it as rental income.
By this way the tax liability will be lower for the corporation. Joel will get deduction on the items like acquisition interest, depreciation, repairs and maintenance, insurance and administrative costs etc. This way the owner of the corporation can avoid double taxation of any gain from the asset’s appreciation and sale.
As there are limited liability for the owner in C Corporation so having more asset with owner and less with corporation is good strategic decision of a volatile industry.
Type two statements.
The first reads user input into person_name. The second reads user input into person_age. Use the int() function to convert person_age into an integer. Note: Do not write a prompt for the input values.

Some variables have been assigned for you and the output statements have been written. Read the starting code carefully before you proceed to the next step. Write the Python code needed to perform the following: Calculate state withholding tax (stateTax) at 6.5 percent Calculate federal withholding tax (federalTax) at 28.0 percent. Calculate dependent deductions (dependentDeduction) at 2.5 percent of the employee’s salary for each dependent. Calculate total withholding (totalWithholding) as stateTax + federalTax + dependentDeduction. Calculate take-home pay (takeHomePay) as salary - totalWithholding Execute the program by clicking the Run button at the bottom. You should get the following output: State Tax: $81.25 Federal Tax: $350.00000000000006 Dependents: $62.5 Salary: $1250.0 Take-Home Pay: $756.25 In this program, the variables named salary and numDependents are initialized with the values 1250.0 and 2. To make this program more flexible, modify it to accept interactive input for salary and numDependents.
Answer:
salary = 1250
numofDependents = 2
stateTax = (6.5/100)*salary
federalTax = (28/100)*salary
dependentDeduction = ((2.5/100)*salary)*(numofDependents)
totalWithHolding = stateTax+federalTax+dependentDeduction
takeHomePay = salary - totalWithHolding
print('State Tax: {}'.format(stateTax))
print('Federal Tax: {}'.format(federalTax))
print('Dependents: {}'.format(dependentDeduction))
print('Salary: {}'.format(salary))
print('Take Home: {}'.format(takeHomePay))
MODIFIED TO ACCEPT FOR SALARY AND NUMBER OF DEPENDENTS
salary = float(input("Please enter your salary: "))
numofDependents = int(input("How many dependents do you have "))
stateTax = (6.5/100)*salary
federalTax = (28/100)*salary
dependentDeduction = ((2.5/100)*salary)*(numofDependents)
totalWithHolding = stateTax+federalTax+dependentDeduction
takeHomePay = salary - totalWithHolding
print('State Tax: {}'.format(stateTax))
print('Federal Tax: {}'.format(federalTax))
print('Dependents: {}'.format(dependentDeduction))
print('Salary: {}'.format(salary))
print('Take Home: {}'.format(takeHomePay))
Explanation:
See the attached screen shot for the input and program output
The input Statement in python is used to receive and store the values for salary and number of dependents
Final answer:
To calculate the taxes and take-home pay in Python, modify the code to accept user input for salary and dependents, then calculate state and federal tax, dependent deductions, total withholding, and take-home pay. The input is processed to dynamically produce the specified outputs, including taxes and deductions.
Explanation:
To calculate the taxes and take-home pay in Python, we would start by modifying the initial code to accept user input for the salary and the number of dependents. This can be done using the input() function in Python. After obtaining these inputs, we apply the specified rates to calculate state withholding tax, federal withholding tax, and dependent deductions. Finally, we calculate the total withholding and take-home pay.
Here is an example of how the code could look:
salary = float(input('Enter your salary: '))
numDependents = int(input('Enter the number of dependents: '))
stateTax = salary * 0.065
federalTax = salary * 0.28
dependentDeduction = salary * 0.025 * numDependents
totalWithholding = stateTax + federalTax + dependentDeduction
takeHomePay = salary - totalWithholding
print(f'State Tax: $',stateTax)
print(f'Federal Tax: $',federalTax)
print(f'Dependents: $',dependentDeduction)
print(f'Salary: $',salary)
print(f'Take-Home Pay: $',takeHomePay)
This code snippet will dynamically calculate the taxes and take-home salary based on the user's input, making the program more useful and interactive.
Implement the make change algorithm you designed in the previous problem. Your program should read a text file "data.txt" where each line in "data.txt" contains three values c, k and n. Please make sure you take your input in the specified order c, k and n. For example, a line in "data.txt" may look like the following:3 4 38
where c = 3,k = 4,n = 38. That is, the set of denominations is {30,31,32,33,34} = {1,3,9,27,81}, and we would like to make change for n = 38. The file "data.txt" may include multiple lines like above.
The output will be written to a file called "change.txt", where the output corresponding to each input line contains a few lines. Each line has two numbers, where the first number denotes a de- nomination and the second number represents the cardinality of that denomination in the solution. For example, for the above input line ‘3 4 38’, the optimal solution is the multiset {27, 9, 1, 1}, and the output in the file "change.txt" is as follows:
27 1 91 12
which means the solution contains 1 coin of denomination 27, one coin of 9 and two coins of denomination

According to a study by Merrill Lynch and Gartner, what percentage of all corporate data is captured and stored in some sort of unstructured form?
Answer:
85 %
Explanation:
Historically, data warehouses had been formed using structured repetitive data that was filtered before entering the data warehouse. However, in recent years, the data warehouse has evolved due to contextual information that can now be attached to unstructured data and that can also be stored.
Those first structured relational data could not be mixed and matched for analytical subjects with unstructured textual data. But with the advent of contextualization, these types of analyzes can now be done naturally and easily.
Classic analytical processing of transaction-based data is performed in the data warehouse as it has always been done. Nothing has changed there. But now you can become analytical about contextualized data, and that form of analysis is new. Most organizations, until now, did not have to base their decision making on unstructured textual data. And now there is a new way of analysis possible in a Data Warehouse: the possibility of mixing analysis. The combined analysis is performed by a combination of structured transactional data and unstructured contextual data.
According to a research by Merrill Lynch indicates that 85 % of all coporate date is stored in some sort of unstructured form like data warehouse.
