What is Prolog?
A logical and declarative programming language, Prolog is also known as PROgramming in LOGics. It is a prime example of a language from the fourth generation that allows declarative programming. This is especially appropriate for applications that use symbolic or non-numeric computing. This is the key justification for Prolog's usage as a programming language in artificial intelligence, where manipulating symbols and inferences are fundamental operations.
For Prolog to automatically solve a problem, we only need to identify the problem; we don't need to specify how it can be addressed. However, in Prolog, we are required to provide hints as a means of solution.
Basically, the prolog language contains three different components:
Facts: A fact is a statement that is true, such as "Tom is the son of Jack," which is a fact.Rules: Rules are conditional truths that have been eliminated. These prerequisites must be met for a rule to be satisfied. For instance, if a rule is defined as:grandfather(X, Y) :- father(X, Z), parent(Z, Y)
This implies that for X to be the grandfather of Y, Z should be a parent of Y and X should be father of Z.
Questions: In order to execute a prolog program, we need to ask certain questions, and the provided facts and rules can help us to find the answers to those questions.Lists in Prolog:
A common data structure used in non-numeric programming is the list. Any number of things make up a list; examples include red, green, blue, white, and dark. The colors [red, green, blue, white, dark] will be used to depict it. Square brackets will enclose the list of components.
Either an empty or non-empty list exists. The list is simply written as a Prolog atom in the first scenario, [ ]. In the second instance, the list consists of the following two items:
the first item of the list, know as the head.the remainder of the list, often known as the tail.Consider a list that looks like this:
[red, green, blue, white, dark].
The tail is [green, blue, white, dark] and the head is [red]. Another list makes up the tail.
Consider that we have a list L = [a, b, c].
The list L can be written as L = [a | Tail]
if we write Tail = [b, c]. The head and tail portions are divided here by the vertical bar (|).
Consequently, the list representation that follow is likewise valid.
[a, b, c] = [a, b, c | [ ] ]
The list for these characteristics can be defined as follows:
a data structure that has two sections—a head and a tail—or is empty. Lists are required for the tail itself.

calculate the first workday based on the project start date in cell h3. place your calculation in cell h6. the first workday will be the start date unless the start date is a weekend day, in which case it will be the next workday. be sure to consider any federal holidays when calculating the next workday.
H6 = IF(WEEKDAY(H3) = 6, H3+3, IF(WEEKDAY(H3) = 7, H3+2, H3)) to calculate the first workday based on the project start date in cell H3, taking into account weekends and federal holidays.
The formula in cell H6 is used to calculate the first workday based on the project start date in cell H3, taking into account weekends and federal holidays. The formula first checks to see if the project start date is a Saturday (weekday 6) and if it is, it adds 3 days to the start date to get the first workday. If the project start date is a Sunday (weekday 7), it adds 2 days to the start date to get the first workday. If the project start date is neither a Saturday nor a Sunday, it returns the project start date as the first workday. This formula is useful for quickly determining the first workday of a project without having to manually check for weekends and federal holidays.

4) Create a text file (you can name it sales.txt) that contains in each line the daily sales of a company for a whole month. Then write a Java application that: asks the user for the name of the file, reads the total amount of sales, calculates the average daily sales and displays the total and average sales. (Note: Use an ArrayList to store the data).
Answer:
Here's an example Java application that reads daily sales data from a text file, calculates the total and average sales, and displays the results:
import java.util.ArrayList;
import java.util.Scanner;
import java.io.File;
import java.io.FileNotFoundException;
public class SalesDemo {
public static void main(String[] args) {
// Ask the user for the name of the file
Scanner input = new Scanner(System.in);
System.out.print("Enter the name of the sales file: ");
String fileName = input.nextLine();
// Read the daily sales data from the file
ArrayList<Double> salesData = new ArrayList<>();
try {
Scanner fileInput = new Scanner(new File(fileName));
while (fileInput.hasNextDouble()) {
double dailySales = fileInput.nextDouble();
salesData.add(dailySales);
}
fileInput.close();
} catch (FileNotFoundException e) {
System.out.println("Error: File not found!");
System.exit(1);
}
// Calculate the total and average sales
double totalSales = 0.0;
for (double dailySales : salesData) {
totalSales += dailySales;
}
double averageSales = totalSales / salesData.size();
// Display the results
System.out.printf("Total sales: $%.2f\n", totalSales);
System.out.printf("Average daily sales: $%.2f\n", averageSales);
}
}
Assuming that the sales data is stored in a text file named "sales.txt" in the format of one daily sale per line, you can run this program and input "sales.txt" as the file name when prompted. The program will then calculate the total and average sales and display the results.
I hope this helps!

Given the following word addresses: 3, 180, 43, 2,191, 88, 190, 14, 181, 44, 186, 253
a. Show the final cache contents for a three-way set associative cache with two-word blocks and a total size of 24 words. Use LRU replacement. For each reference identify the index bits, the tag bits, the block offset bits, and if it is a hit or a miss.
b. Show the final cache contents for a fully associative cache with one-word blocks and a total size of 8 words. Use LRU replacement. For each reference identify the index bits, the tag bits, and if it is a hit or a miss.
c. What is the miss rate for a fully associative cache with two-word blocks and a total size of 8 words, using LRU replacement? What is the miss rate using MRU (most recently used) replacement? Finally what is the best possible miss rate for this cache, given any replacement policy?
Answer:
A. index bits = 2, tag bits = 2, block offset bits = 1, it is a miss.
B. index bits = 2, tag bits = 1, block offset bits = 0, it is a hit
C. the miss rate is 0
Explanation:
a. number of blocks = 12
number of blocks per set = 3
number of set = number of blocks / number of blocks per set = 12/3 = 4
word size = 24
block size = 2
the block offset = \(log_{2}\) block size
= \(log_{2}\) 2 = 1
the index bits = \(log_{2}\) number of set = \(log_{2}\) 4 = 2
the tag bits = (\(log_{2}\) word size) - offset - index = (\(log_{2}\) 24) -2 - 1 = 5 -2 - 1 = 2
b. word size = 8
block size = 1
the block offset = \(log_{2}\) block size
= \(log_{2}\) 1 = 0
the index bits = \(log_{2}\) number of set = \(log_{2}\) 4 = 2
the tag bits = (\(log_{2}\) word size) - offset - index = (\(log_{2}\) 8) -2 - 1 = 3 - 0- 2= 1

Alice the number theorist knows the rule for testing if a numbernis divisible by 3:
n is divisible by 3 if and only if the sum of the digits ofnis divisible by 3.
When Alice visits Mars, she finds that the Martians have six hands, and six fingers on eachhand, so that they count in base 36. In base 36, Alice’s divisibility test doesn’t work for testing divisibility by d= 3. But it does work for one of the d listed below. Which one?
a. 4
b. 7
c. 10
d. 11
e. 15
Answer:
e. 15
Explanation:
Alice is conducting a test which is to find that a number is divisible by 3 only if the sum of the digits is divisible by 3. The sum will be divisible by 3 but the digits may not be divisible by 3. In the case of Martians the number 36 is divisible by 3 but the sum is not divisible by 3. Same will be the case with 15. The number 15 is divisible by 3 but the sum may not be divisible by 3 and therefore the test will not work.

What is data type?
A data type is a set of possible values and operations that may be performed on it in computer science and programming. A data type specifies how the programmer intends to use the data to the compiler or interpreter. Most programming languages support integer numbers (of various sizes), floating-point numbers (which approximate real numbers), characters, and Booleans as basic data types. A data type limits the potential values of an expression, such as a variable or a function. This data type specifies the actions that may be performed on the data, its meaning, and how values of that kind can be stored.
