Write a program that uses linear recursion to generate a copy of an original collection in which the copy contains duplicates of every item in the original collection. Using linear recursion, implement a function that takes a list as user-supplied runtime input and returns a copy of it in which every list item has been duplicated. Given an empty list the function returns the base case of an empty list.

Answers

Answer 1

Answer: b

Explanation:

Answer 2

Program using linear recursion to duplicate items in a list:

def duplicate_list(lst):

   if not lst:

       return []

   else:

       return [lst[0], lst[0]] + duplicate_list(lst[1:])

# Example usage

user_input = input("Enter a list of items: ").split()

original_list = [item for item in user_input]

duplicated_list = duplicate_list(original_list)

print("Duplicated list:", duplicated_list)

How can a program use linear recursion to duplicate items in a list?

By implementing a function that utilizes linear recursion, we can create a copy of an original list with duplicated items. The function duplicate_list takes a list lst as input and checks if it is empty. If the list is empty, it returns an empty list as the base case.

Otherwise, it combines the first item of the list with itself and recursively calls the function with the remaining items (lst[1:]). The duplicated items are added to the resulting list. This process continues until all items in the original list have been duplicated and the duplicated list is returned.

Compute the acceleration of gravity for a given distance from the earth's center, distCenter, assigning the result to accelGravity. The expression for the acceleration of gravity is: (G * M) / (d2), where G is the gravitational constant 6.673 x 10-11, M is the mass of the earth 5.98 x 1024 (in kg) and d is the distance in meters from the earth's center (stored in variable distCenter).
#include
using namespace std;
int main() {
double G = 6.673e-11;
double M = 5.98e24;
double accelGravity;
double distCenter;
cin >> distCenter;
/* Your solution goes here */
cout << accelGravity << endl;
return 0;
}

Answers

Answer:

Replace /* Your solution goes here */ with the following expression

accelGravity = (G * M) / (distCenter *distCenter );

Explanation:

Required

Complete the code

The equivalent expression of (G * M) / (d^2) is:

(G * M) / (distCenter *distCenter );

The expression must be stored in accelGravity.

So, we have:

accelGravity = (G * M) / (distCenter *distCenter );

You are consulting with another medium sized business regarding a new database they want to create. They currently have multiple normalized source databases that need consolidation for reporting and analytics. What type of database would you recommend and why

Answers

Answer:

The enormous amount of data and information that a company generates and consumes today can become an organizational and logistical nightmare. Storing data, integrating it and protecting it, so that it can be accessed in a fluid, fast and remote way, is one of the fundamental pillars for the successful management of any company, both for productive reasons and for being able to manage and give an effective response to the customers.

Good big data management is key to compete in a globalized market. With employees, suppliers and customers physically spread across different cities and countries, the better the data is handled in an organization, the greater its ability to react to market demand and its competitors.

Databases are nowadays an indispensable pillar to manage all the information handled by an organization that wants to be competitive. However, at a certain point of development in a company, when growth is sustained and the objective is expansion, the doubt faced by many managers and system administrators is whether they should continue to use a database system, or if they should consider the leap to a data warehouse. When is the right time to move from one data storage system to another?

2.13 LAB: Branches: Leap Year
A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the
difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The
requirements for a given year to be a leap year are:
1) The year must be divisible by 4
2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400
Some example leap years are 1600, 1712 and 2016.
Write a program that takes in a year and determines whether that year is a leap year.
Ex If the input is
1712
the output is
1712 13 leap year.
Ex If the nouts

Explanation:

I don't know what is so special about Coral but here we go. I couldn't find and IDE that supported Coral so I just used their Coral simulator on their website. The first if statement on line 5 determines if the number is divisible by 400. If so, the leap year is on a century year e.g 1900 1800. If not, the else statement will be executed and the second if statement will execute. If the number is divisible by 4, it is a leap year. If not, the else statement gets executed in which case the number was not a century leap year or a leap year. After that the program terminates.

Hope this helped :)  If it didn't let me know and I do my best to find out what went wrong.

If your organization hires a new employee, what would you do to create a user account in the Linux system and add the account to a group? What commands would you use? What configuration files would you check and modify?

Answers

Following are the responses to this question:

The user account is "olivia".In the Linux system to see the account go to the "/home directory".For the configuration file we use ".bash_logout , .bash_profile, and .bashrc" files.

Creating users:

We will use the useradd command to achieve this. Using that same command, you can create users who would log in or customers who would log in (in the case of creating a user for a software installation).

In its basic form, the command is as follows:

[Options] useradd username

Take this user olivia, for instance. Assuming that you had been to issue the command prompt:

olivia has become a user.

Users are added to the system without the need for a home directory and are unable to log on. It if we were using this rather than running the command without arguments?

sudo using useradd -m olivia

Using the command above, a new user would be created, including a home directory that corresponded to the username. That means that you might now see the name "olivia" in the directory "/home".

But what about the lockout concern that was raised earlier? Both these methods are possible. After creating the user, you can enter the following command:

Password for olivia is: sudo passwd olivia

You'll be requested to enter & verify your new password once you've completed the process. This unlocks the user profile, allowing them to log in.

This command might look like if you wanted to accomplish it in one go:

sudo useradd -m olivia -p PASSWORD

You should be using Passcodes as the login for the user olivia.

As soon as the user logs in, he or she can update their account password by using the password command to input their current password, and afterward entering/verifying their new one.

To create a user that has no personal account and cannot log in, execute the following instructions:

sudo use useradd as  the-M USERNAME ​sudo use usermod as the -L USERNAME

The user to be added is identified by USERNAME.

It establishes a user with really no root folder and prevents them from signing in with a second operation.

To add an existing user to a group on Linux, follow the instructions:

As root, log in to your accountUse the useradd instruction to add a new user (for example, useradd roman)If you'd like to log on as a new customer, type su plus that user's name.Entering the word "exit" will logout you from your account.

Another way to add a user to a group under Linux would be to use the following syntax:

Alternatively, you can use the usermod command.The name of the club should be substituted for example group in this sentence.Example username should be replaced with the name of the user you'd like added.

The following operations are performed when a new login is added to the system.

The user's home directory (/home/username by default) is now created.To set configuration files for the user's session, the following secret files are copied into another user's home directory.

.bash_logout

.bash_profile

.bashrc

/var/spool/mail/username includes the user's mail spool.The new user account is arranged in groups with the same name.
