The `IterativeCrawler` class in Java uses a queue to perform iterative web crawling. It visits pages, extracts information, adds links to the queue, and continues until the queue is empty.

Here's an example of a Java class called `IterativeCrawler` that implements a iterative web crawler using loops:

```java

import java.util.Queue;

import java.util.LinkedList;

public class IterativeCrawler {

   public void crawl(String startingUrl) {

       Queue<String> queue = new LinkedList<>();

       queue.add(startingUrl);

       while (!queue.isEmpty()) {

           String url = queue.poll();

           // Visit the page and perform desired actions

           // Get the links from the page

           // Add the links to the queue for further crawling

           // Example: printing the visited URL

           System.out.println("Visited URL: " + url);

       }

   }

   public static void main(String[] args) {

       IterativeCrawler crawler = new IterativeCrawler();

       crawler.crawl("https://example.com");

   }

}

The `IterativeCrawler` class uses a queue data structure to implement the iterative crawling process. It starts by adding the starting URL to the queue. Then, in a loop, it retrieves a URL from the front of the queue using the `poll()` method. Inside the loop, you can perform the desired actions on the visited page, such as extracting information or storing data.

After visiting the page, you can retrieve the links from the page and add them to the queue for further crawling. This ensures that all the linked pages will be visited in a breadth-first manner. In the example code, we are simply printing the visited URL as an illustration of the crawling process.

In the `main` method, an instance of `IterativeCrawler` is created, and the `crawl` method is called with the starting URL as an argument.

By using a loop and a queue, the `IterativeCrawler` class allows for an iterative approach to web crawling, visiting pages in a controlled manner until the queue is empty.

Here's an example code in Python that calculates the average prices of petrol for different tenures and checks if any of the tenures has an average price higher than 20:

# Petrol prices for different tenures

prices_1999_2003 = [12, 11, 12, 15, 15]

prices_2004_2008 = [17, 18, 18, 18, 19]

prices_2009_2013 = [23, 34, 23, 23, 23]

# Calculate average prices

avg_prices = []

avg_prices.append(sum(prices_1999_2003) / len(prices_1999_2003))

avg_prices.append(sum(prices_2004_2008) / len(prices_2004_2008))

avg_prices.append(sum(prices_2009_2013) / len(prices_2009_2013))

# Check if any tenure has an average price higher than 20

if any(avg_price > 20 for avg_price in avg_prices):

   print("The price of petrol in this tenure is unusually high")

In this code, we first store the petrol prices for each tenure in separate lists (prices_1999_2003, prices_2004_2008, prices_2009_2013). Then, we calculate the average price for each tenure by dividing the sum of prices by the number of prices. The average prices are stored in the avg_prices array.

Finally, we use the any function with a generator expression to check if any average price in avg_prices is higher than 20. If so, the statement "The price of petrol in this tenure is unusually high" is printed.

This code provides a straightforward way to calculate average prices and identify tenures with unusually high petrol prices.

The correct term to fill in the blank is "inefficient" with arrays.

The deletion operation with arrays can be inefficient due to the nature of arrays being contiguous blocks of memory. When an element is deleted from an array, it leaves an empty space that needs to be filled. In order to maintain the order of the remaining elements, all subsequent elements must be shifted down to fill the gap. This process, known as shifting, can be time-consuming, especially when dealing with large arrays.

For example, let's say we have an array of size n, and we want to delete an element at index k. To maintain the order, we need to shift n-k-1 elements down by one position. This requires moving each element individually, resulting in a time complexity of O(n). As a result, the larger the array, the more time it takes to perform the deletion operation.

In contrast, other data structures like linked lists provide a more efficient solution for deletions. Linked lists allow for easy removal of elements by simply adjusting the pointers that connect the nodes. This process does not require shifting elements, making it faster and more efficient for deletions.

Server-side development includes designing, building, and maintaining web applications and websites that operate on the server-side. Communication to the client side with REST API style is achieved by creating a RESTful API endpoint that receives HTTP requests and responds with a JSON object.

The API endpoints can accept any HTTP method, including GET, POST, PUT, and DELETE.  REST stands for Representational State Transfer. It is an architectural design approach for building web services. RESTful API makes use of the HTTP methods that are familiar to web developers such as GET, POST, PUT, and DELETE. This approach enables stateless, cacheable, and client-server communication.

The principal object provides security services. In Java, a principal object is an interface that represents an entity's identity. This object is used in security operations, such as authenticating and authorizing a user's access to resources. The authenticator, on the other hand, verifies the user's identity through authentication. An authenticator is responsible for confirming that a user is who they say they are.

Java annotations are a form of metadata that can be added to a Java class or method. They can be used to provide additional information about a class or method, such as its security requirements, which can be used by the operating system security to provide better security.

Loops are prevented in BGP (Border Gateway Protocol) routing through schemes such as the Poisoned Reverse. The inclusion of all domains in a route does not prevent loops. Loops can occur in BGP routing but are mitigated and handled through various mechanisms.

BGP is a routing protocol used in the Internet to exchange routing information between different autonomous systems (ASes). To prevent loops in BGP routing, various schemes are employed, with one commonly used scheme being the Poisoned Reverse. In this scheme, a route that points back to the originator of the route is advertised with a high cost, effectively poisoning the route and preventing loops from forming.

Contrary to the statement, including all domains in a route does not inherently prevent loops. Loop prevention in BGP is not solely dependent on including all domains in a route, but rather on the implementation of loop prevention mechanisms and protocols.

While loops can occur in BGP routing, they are generally handled and mitigated through mechanisms such as path selection algorithms, loop detection, and route advertisement policies. BGP routers utilize sophisticated algorithms and routing tables to make informed decisions and prevent loops from persisting in the routing infrastructure.

It is important to note that the design of BGP, including its loop prevention mechanisms, does not guarantee the absence of loops. However, BGP's design and implementation aim to minimize the occurrence and impact of loops by employing various techniques and protocols to ensure stable and efficient routing in complex network environments.

Graphical passwords offer several advantages compared to text passwords, including ease of deployment, faster input, and improved resistance to vulnerabilities.

One advantage of graphical passwords is that they are easier to deploy. Text passwords often require users to come up with unique combinations of characters, which can be challenging to remember and may lead to password reuse. In contrast, graphical passwords allow users to select images, patterns, or shapes as their passwords, which can be visually memorable and intuitive.

Another advantage is that graphical passwords typically take less time to input. Users can select or draw their chosen pattern or image quickly, reducing the time it takes to authenticate themselves. This can be especially beneficial in situations where fast access is essential, such as logging into a mobile device or accessing frequently used accounts.

Additionally, graphical passwords offer improved resistance to certain vulnerabilities. Traditional text passwords are susceptible to brute force attacks and dictionary-based cracking attempts. However, graphical passwords based on unique patterns or images can be more resilient to such attacks, as the potential combinations are significantly larger and harder to guess.

In conclusion, graphical passwords provide advantages in terms of ease of deployment, faster input, and increased resistance to vulnerabilities compared to traditional text passwords. However, it is important to note that graphical passwords also have their own set of challenges, such as potential usability issues and the need to protect against shoulder-surfing attacks. Therefore, a careful evaluation of the specific requirements and user preferences is necessary before implementing graphical password systems.

The main difference between a call-by-reference parameter and a call-by-value parameter is that a call-by-reference parameter passes the memory address of the actual argument, allowing the function to modify the original value, while a call-by-value parameter passes a copy of the value, and any changes made within the function do not affect the original value.

In call-by-value parameter passing, a copy of the argument's value is passed to the function. This means that any modifications made to the parameter within the function do not affect the original value of the argument. The function works with its own local copy of the data, ensuring that the original value remains unchanged. This method is useful when the function does not need to modify the original value or when the value is a primitive data type.

On the other hand, in call-by-reference parameter passing, the memory address of the argument is passed to the function. This allows the function to directly access and modify the original value of the argument. Any changes made to the parameter within the function will reflect in the original variable. This method is useful when the function needs to modify the original value or when the value is a large data structure that would be inefficient to pass by value.

Call-by-reference allows for efficient data manipulation and avoids unnecessary memory usage by directly accessing the original value. However, it should be used with caution, as it can lead to unexpected changes if not handled properly. Call-by-value, on the other hand, provides a safer approach by keeping the original value intact but may result in performance overhead when dealing with large data structures. The choice between the two parameter passing methods depends on the specific requirements of the program and the intention of the function.

The given statement "A denial-of-service attack is an attempt to compromise availability by hindering or blocking completely the provision of some service." is true.

What is a denial-of-service (DoS) attack?

A denial-of-service (DoS) attack is an effort to deny legitimate users access to a network, machine, or device by overwhelming it with traffic or sending it data that triggers a crash.

Flooding the target with useless traffic or sending it a certain number of messages can cause a DoS attack to succeed.

The flood of incoming traffic makes it difficult or impossible for the intended traffic to access the network or website, resulting in denial-of-service to legitimate users.

The main objective of a DoS attack is to drain the resources of a machine, rendering it inaccessible to its intended users.

The script first checks if the number of arguments passed is not equal to two, in which case it outputs an error message and exits with status 1. It then checks if the two files given exist, and if not, outputs an appropriate error message and exits with status 1.

If both files exist, the script creates backups of the original files by copying them to new files with the ".backup" extension. It then copies the contents of file1 to a temporary file, file1.temp. It then copies the contents of file2 to file1, and the contents of file1.temp to file2. Finally, it outputs a success message.

The minimum spanning tree (MST) of the given graph can be obtained using Kruskal's algorithm. The MST is a subgraph that connects all the vertices of the original graph with the minimum total weight. By applying Kruskal's algorithm, we can determine the edges that form the MST.

First, let's sort the edges of the graph in non-decreasing order of their weights: (A, F) with weight 9, (A, G) with weight 10, (B, F) with weight 12, (A, B) with weight 18, and (B, G) with weight 30.

Starting with an empty MST, we consider each edge in the sorted order and add it to the MST if it does not create a cycle. The first edge is (A, F) with weight 9, so we add it to the MST. The next edge is (A, G) with weight 10, and we add it as well. The third edge is (B, F) with weight 12, and it is also added. Adding (A, B) with weight 18 would create a cycle, so we skip it. Finally, we add the edge (B, G) with weight 30.

The MST, shown in the graph, includes the edges (A, F), (A, G), (B, F), and (B, G). These edges are added in the order of their weights, forming the minimum spanning tree for the given graph. The total weight of the MST is 9 + 10 + 12 + 30 = 61.

Using the cache makes the computer work faster, even if you only access or save data once. This is because the cache uses a faster storage than the normal memory.

In today's computers, the cache is a small and fast memory that is closer to the processor than the main memory. It helps connect the processor and memory so they can work together smoothly even though they work at different speeds.

To add two matrices, the computer needs to get each number from the memory and put it in a special place called the processor. Then it can do the math and give you the answer. If the cache is on, it checks if the information needed is already in there. If the data is there, the computer can get it fast which makes it faster.

You have a piece of code, written in C, which adds element by element two matrices: It compute the matrix C (C=A+B) such as C[i,j]=A[i,j]+B[i,j]. Thus, each element of A and B is only accessed one and each element of C written once.

You have a computer for which you can easily activate or desactive all caches and you do the following experiments to see the effect of caches:

1. shutdown the computer

start the computer (with or without caches activated)

As soon the computer is started, launch the software and get the running time.

You repeat this experiment several times, with and without caches activated. By shutting down the computer, you are sure that caches, if used, are empty. The experiments are clear: each time the cache is activated, the running time is by a large extend smaller.

Can you explain why to activate the cache speeds up the computational time even if data are accessed or written once? (C is not written on the disk, just computed and stored in memory)

Answer:Given a piece of code written in C language which adds elements by elements two matrices, which computes matrix C such that C = A + B as C[i,j] = A[i,j] + B[i,j]. Here, each element of A and B is accessed only once.

:In the given code, two matrices A and B are added element-wise, and the resultant matrix C is stored in a separate variable. The matrix elements are accessed only once as all the elements of A and B are being added to generate matrix C.The code is written in such a way that the elements of matrices A and B are accessed simultaneously and added element-wise.

The resultant matrix C is obtained by adding the corresponding elements of matrices A and B. This code is highly optimized and efficient as it accesses the elements of A and B only once while adding them together to get the resultant matrix C.

MyClass is designed with iter() and next() functions that facilitate iterating over an object, here used for generating and providing prime numbers from a list of 20 random integers.

An additional class method validates if the provided argument is a dictionary and then prints all dictionary elements sorted by values. The iter() method creates an object property counter and a list of 20 random integers. The next() function provides a random prime number from the list until the counter reaches 10, after which the object stops being iterable. The class method checks the type of argument, prompts a type error if not a dictionary, and if it is, prints all elements sorted by values.
