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

Explanation:

Final answer:

The question involves creating a program in Computers and Technology to calculate the distance of free-fall in meters and feet over 10 seconds using physics formulas and programming methods for calculations and conversions.

Explanation:

The student's question involves writing a program that calculates the distance an object falls in meters over 10 seconds, as well as converting that distance to feet. This problem applies the physics concept of free-fall, using the equation of motion h = (1/2) * g * t^2, where h is the height, g is the acceleration due to gravity (9.81 m/s2), and t is the time in seconds. The student should also write a method to convert the distance from meters to feet (1 meter = 3.28084 feet).

The main method should include a loop that calls these methods to generate a table of distances fallen and the corresponding times. To convert meters to feet, the following formula can be used:

feet = meters * 3.28084

Answer:

Program for the above question in python:

mass = float(input("Enter the mass in grams")) # It is used to take the mass as input.  

density = float(input("Enter the density grams per cm cube")) # It is used to take the input for the grams.

print("Volume ={:.2f}".format(mass/density)) #It is used to print the Volume.

Output:

Explanation:

To write a program that calculates and outputs the volume of an object using mass and density, you need to collect the mass and density from the user as input and use the formula volume = mass / density. Format the output to two decimal places using a print or format function that specifies the decimal precision.

To write a program that calculates and outputs the volume of an object using mass and density, you would need to collect the mass and density from the user as input. Then, you can use the formula volume = mass / density to calculate the volume. To format the output to two decimal places in most programming languages, you can use a print or format function that specifies the decimal precision. Here's an example in Python:

This program prompts the user to enter the mass and density, calculates the volume using the formula, and then formats the output to two decimal places using the '{:.2f}' format specifier.

The student's question is about creating a Python program to map names to phone numbers using a dictionary, where after inputting contacts, the program can search for and retrieve phone numbers by name.

Explanation:

The student's question involves writing a program to manage a list of contacts, specifically to map names to phone numbers. To solve this task, one would typically use a data structure known as a dictionary in programming, where each name (key) is associated with a corresponding phone number (value). Below is a simple example of how one could write such a program in Python:

# Prompt for the number of contacts
N = int(input('Enter the number of contacts: '))
# Initialize an empty dictionary to store contacts
contacts = {}
# Loop to enter the contacts into the dictionary
for _ in range(N):
   name, phone_number = input('Enter contact name and phone number: ').split()
   contacts[name] = phone_number
# Prompt for the name to search
search_name = input('Enter a name to search for their phone number: ')
# Output the phone number for the given name
if search_name in contacts:
   print(f'The phone number for {search_name} is {contacts[search_name]}')
else:
   print('Name not found in contact list.')
This script takes the number of contacts as input, then iterates and adds each name-phone pair to the contacts dictionary. When the user enters a name to search, the program looks up the name in the dictionary and prints out the associated phone number if found.

Final answer:

To solve the programming exercise, include cin to read two strings representing the first and last name, then output them in 'Last name, First name' format using cout, followed by a newline.

Explanation:

To complete the coding exercise, you need to read in a person's first and last name and then display the last name followed by a comma, and then the first name. You can achieve this by using the cin to read the names and cout to output the result in the required format.

The program will look like this:

#include
#include
using namespace std;
int main() {
   string firstName;
   string lastName;
   // Reading the first and last name
   cin >> firstName >> lastName;
   // Output in 'Last name, First name' format
   cout << lastName << ", " << firstName << endl;
   return 0;
}

Simply include the code segment within the "/* Your solution goes here */" section in your program. When you run this code, it will prompt you to input a first and last name, and after you provide it, the program will print out the last name, a comma, and then the first name followed by a newline as specified in the exercise.

Eucalyptus is the correct choice for creating a privately hosted computing infrastructure with easy interaction with AWS products, offering compatibility through AWS APIs.

Craig is looking for a solution to create a computing infrastructure that allows for internal hosting but also provides ease of interaction with AWS services. The correct answer to this question is c. Eucalyptus. Eucalyptus is an open-source software platform that enables organizations to implement on-premises Infrastructure as a Service (IaaS) clouds with strong compatibility with AWS products.

It allows businesses to create private clouds that are interoperable with AWS, using AWS APIs to manage resources within the Eucalyptus private cloud. This means developers can use the same tools and skills they would for AWS, providing a seamless transition between the private cloud and AWS services when needed for scalability or additional services.

Explanation:

What happens is that the security of a company's information and data system can be affected by its people because it is the organization's own employees who can leak sensitive information, for their own benefit or for the benefit of others. That is why it is extremely relevant that organizations should limit the level of access that each user has to their information system.

Adequate training in the use of these systems is essential for employees to use it properly, to correct system failures, and for top management to have adequate knowledge in the preparation of system security plans.

It is the security policies that will prevent unauthorized access and greater control over the security of important data and information, so it is important that any company with a data information system keeps itself up to date with the software and implements necessary security resources, in a way maintain security and always update and analyze the operation of technological equipment.

Answer:

Routing table and routing table population.

Explanation:

A router is an intermediate network device used to determine a good path for routing packets. It is a layer 3 device. Each interface of the router is a broadcast domain, that is, it represents a network.

It uses its routing table to find paths to a network. The router's routing table can populated (to add more routes) statically and dynamically.

To populate a routing table statically, use the format, "IP rout 'network address' 'subnet mask' 'next hop address'".

To populate dynamically, the protocols like RIP, OSPF, BGP, EIGRP etc, are used. The static routing is good for small networks because routing table population is manual while dynamic routing is good for large networks because it's routing table population is automatic.
