The answer is "Its fundamental economic structure of IP, which is based on the concept of incentives".

Explanation:

In the given question the correct choice is missing so, its solution can be defined as follows:

It is a copyrighted category that includes subjective human mind works. which exists in different forms, and also some countries recognize much more than others. Copyright laws, patents, trade secrets, and trademarks are the most famous types.

This is a law that promotes the creation of a broad range of intellectual goods.
To do just that, the law gives the information and creative goods made, generally for a limited time, rights to individuals and companies.

In an array based implementationof a queue a possible solution to dealing with the full condition is to

kati45 [8]

Answer:

D. Maintain a count of queue items.

Explanation:

For checking the full condition of a queue you have to check whether the number of elements in the array are equal to the size of the array.If they are equal then we can that the queue is full.

Checking frontindex equal to backindex is for checking if the queue is empty.

In option C we have to check for arrayFullException but it will not be a good approach.

So we conclude by saying that the answer is option D.

- Consider the relation R = {A, B, C, D, E, F, G, H, I, J} and the set of functional dependencies F = { {B, C} -> {D}, {B} -&

Olenka [21]

Answer:

The key of R is {A, B}

Explanation:

A key can be seen as a minimal set of attributes whose closure includes all the attributes in R.

Given that the closure of {A, B}, {A, B}+ = R, one key of R is {A, B} But in this case, it is the only key.

In order for us to to normalize R intuitively into 2NF then 3NF, we have to make use of these approaches;

First thing we do is to identify partial dependencies that violate 2NF. These are attributes that are

functionally dependent on either parts of the key, {A} or {B}, alone.

We can calculate

the closures {A}+ and {B}+ to determine partially dependent attributes:

{A}+ = {A, D, E, I, J}. Hence {A} -> {D, E, I, J} ({A} -> {A} is a trivial dependency)

{B}+ = {B, F, G, H}, hence {A} -> {F, G, H} ({B} -> {B} is a trivial dependency)

To normalize into 2NF, we remove the attributes that are functionally dependent on

part of the key (A or B) from R and place them in separate relations R1 and R2,

along with the part of the key they depend on (A or B), which are copied into each of

these relations but also remains in the original relation, which we call R3 below:

R1 = {A, D, E, I, J}, R2 = {B, F, G, H}, R3 = {A, B, C}

The new keys for R1, R2, R3 are underlined. Next, we look for transitive

dependencies in R1, R2, R3. The relation R1 has the transitive dependency {A} ->

{D} -> {I, J}, so we remove the transitively dependent attributes {I, J} from R1 into a

relation R11 and copy the attribute D they are dependent on into R11. The remaining

attributes are kept in a relation R12. Hence, R1 is decomposed into R11 and R12 as

follows: R11 = {D, I, J}, R12 = {A, D, E} The relation R2 is similarly decomposed into R21 and R22 based on the transitive

dependency {B} -> {F} -> {G, H}:

R2 = {F, G, H}, R2 = {B, F}

The final set of relations in 3NF are {R11, R12, R21, R22, R3}

g Design a Boolean function called isPrime, that accepts an integer as an argument and returns True if the argument is a prime n

professor190 [17]

Answer:

#include <bits/stdc++.h>

using namespace std;

bool isPrime(int n)

{

for(int j=2;j<=n-1;j++) //loop to check prime..

{

if(n%j==0)

return false;

}

return true;

}

int main(){

int n;

cout<<"Enter the integer"<<endl;//taking input..

cin>>n;

if(isPrime(n))//printing the message.

{

cout<<"The number you have entered is prime"<<endl;

}

else

{

cout<<"The number is not prime"<<endl;

}

return 0;

}

Output:-

Enter the integer

The number you have entered is prime

Explanation:

The above written program is in C++.I have created a function called isPrime with an argument n.I have used a for loop to check if the number is prime or not.In the main function I have called the function isPrime for checking the number is prime or not.

The Yuba College Library would like a program to calculate patron fines for overdue books. Fines are determined as follows: Pape

mestny [16]

Answer:

Explanation:

The following Python code creates all of the necessary functions in order to request and validate all of the inputs from the user. Once everything is entered and validated it calculates the total fee and outputs it to the user. Also calls the entire class at the end using a test variable...

class Customer:

library_card = 0

patrons_name = ""

patrons_address = ""

type_of_book = ""

book_title = ""

days_overdue = 0

fee = 0.0

book_list = ['paperback regular', 'paperback best seller', 'magazine', 'hardcover']

def __init__(self):

self.library_card = self.get_library_card()

self.patrons_address = input("Patron's Address: ")

self.book_title = input("Book Title: ")

self.type_of_book = self.get_type_of_book()

self.days_overdue = float(self.get_days_overdue())

self.calculate_total()

print("Your total Fee is: " + str(self.fee))

def get_library_card(self):

library_card = int(input("Enter 4-digit library card number: "))

if (type(library_card) == type(0)) and (len(str(library_card)) == 4):

return library_card

else:

print("Invalid Card number:")

self.get_library_card()

def get_type_of_book(self):

type_of_book = input("Type of Book 1-4: ")

if (int(type_of_book) > 0) and (int(type_of_book) <= 4):

return int(type_of_book)

else:

print("Invalid Type")

self.get_type_of_book()

def get_days_overdue(self):

days_overdue = input("Number of Days Overdue: ")

if int(days_overdue) >= 0:

return days_overdue

else:

print("Invalid number of days")

self.get_days_overdue()

def calculate_total(self):

if self.type_of_book == 1:

self.fee = 0.20 * self.days_overdue

if self.fee > 8:

self.fee = 8

elif self.type_of_book == 2:

self.fee = 0.50 * self.days_overdue

if self.fee > 15:

self.fee = 15

elif self.type_of_book == 3:

self.fee = 0.25 * self.days_overdue

if self.fee > 5:

self.fee = 5

else:

self.fee = 0.30 * self.days_overdue

if self.fee > 23:

self.fee = 23
