C, a replacement for the programming language B, was initially created by Ritchie at Bell Labs between 1972 and 1973 to create utilities for Unix.
Thus, It was used to re-implement the Unix operating system's kernel. C increasingly gained popularity in the 1980s.
With C compilers available for almost all current computer architectures and operating systems, it has grown to be one of the most popular programming languages.
The imperative procedural language C has a static type system and supports recursion, lexical variable scoping, and structured programming. It was intended to be compiled, with minimal runtime assistance, to offer low-level memory access and language constructs that easily map to machine instructions.

Your New Class Must
The goal of this assignment is to write an alternative implementation of the List abstract data
type: the Linked List. Your implementation will support all of the same functionality as the
ArrayList implemented in class
1)
Begin by creating a new class, LinkedList, that implements the generic List interface that was created in class. Your new class must also be fully generic. For now, just stub out all of the methods.
2. LinkedList class will not use arrays in any way. Instead, you will store values in a linked sequence of nodes. Use the same generic Node class that was used in the NodeQueue created in class. Add the following fields to your class:
a. A head Node.
b. A tail Node.
c. The current size of the list.
3. Create a parameterless constructor that initializes all three fields. The head and tail
should both initially be null, and the size should be 0.
4. The easiest method to implement is size(); simply return the current size of the list.
5. The next easiest method to implement is the append(E value) method.
a. Create a new Node to hold the new value.
b. If the size of the list is 0, the new Node becomes both the head and tail of the list.
c. Otherwise, the new Node becomes the new tail. (Remember to set the new Node as the current tail's next Node before changing the tail)
d. Increment size.
6. The get(int index) method is slightly more complex to implement than the other methods that you will have implemented so far. This is because a linked sequence of nodes does not support random access - there is no way to jump directly to a specific node in the sequence. Instead, you need to "walk the list" by starting at the head and counting nodes until you arrive at the correct index.
You can accomplish this by creating a counter that starts at 0 and, beginning at the head, moving from one node to the next. Each time you move to the next node, increment the counter. When the counter is equal to the index, you have found the right node. If you reach the end of the list first, you should throw a java.lang.IndexOutOfBoundsException.
7. Implement the set(int index, E value) method. You will use an algorithm very similar to the one in the get(int index) method. Note that you will need to modify the Node class so that you can change the value stored in the Node
To implement the LinkedList class, follow the steps provided:
1. Create a new class called LinkedList that implements the generic List interface.
2. Define generic type parameters for the LinkedList class.
3. Create two instance variables: `head` and `tail` of type Node<T>, and `size` of type int. Initialize `head` and `tail` as null, and `size` as 0 in the parameterless constructor.
4. Implement the `size()` method to return the current size of the list (i.e., the value of `size`).
5. Implement the `append(E value)` method:
a. Create a new Node<T> with the given value.
b. If the size of the list is 0, set both `head` and `tail` to the new Node.
c. Otherwise, set the current `tail`'s next Node to the new Node and update `tail` to the new Node.
d. Increment `size`.
6. Implement the `get(int index)` method:
a. Check if the index is within valid bounds (0 <= index < size). If not, throw an IndexOutOfBoundsException.
b. Create a variable `current` and set it to `head`.
c. Iterate through the list using a loop, incrementing a counter until reaching the desired index or the end of the list.
d. If the desired index is found, return the value of the `current` Node.
e. If the end of the list is reached before the desired index, throw an IndexOutOfBoundsException.
7. Implement the `set(int index, E value)` method:
a. Follow the same steps as the `get(int index)` method to validate the index.
b. Once the desired index is found, update the value of the `current` Node to the given value.

Answer:
A computer monitor is an electronic device that displays digital images generated by a computer's graphics card. It is one of the essential components of a computer system, allowing users to interact with the computer and view its output. Monitors come in various sizes, resolutions, and display technologies such as LCD, LED, OLED, and CRT.
Modern computer monitors usually have a flat-panel display, which is thinner and consumes less power than the older CRT (cathode ray tube) monitors. Monitors can be connected to the computer through various interfaces, such as VGA, DVI, HDMI, and DisplayPort, and some models have built-in speakers or USB ports for added functionality.
The resolution of a monitor determines the number of pixels it can display horizontally and vertically, with higher resolutions providing more screen real estate and sharper images. Refresh rate is another important factor, with higher refresh rates allowing for smoother motion and reducing eye strain.
In summary, a computer monitor is an essential component of a computer system that displays visual output to the user, and choosing the right monitor for your needs depends on factors such as size, resolution, display technology, and connectivity options.

Symmetric encryption and decryption is a type of cryptography in which the same key is used to both encrypt and decrypt data.
The process involves taking plain text or unencrypted data and using a symmetric algorithm to transform it into ciphertext or encrypted data. The key used to encrypt the data is also used to decrypt it, which means that both parties must have access to the same key in order to securely communicate. The symmetric key is kept secret to prevent unauthorized access to the data. When the encrypted data is received, the receiver uses the same key to decrypt it back into plain text. This process ensures that only the intended recipient can access the original message or data.

a bubble sort is being used to arrange the following set of numbers in ascending order: 7 5 3 9 2 6 after the first pass of the sort is completed, what order will the data be in?
After the first pass of the Bubble Sort algorithm, the largest number in the set will "bubble" up to the end of the list.
Here's the step-by-step process of the first pass:
Compare 7 and 5. Since 7 is greater than 5, swap them: 5 7 3 9 2 6
Compare 7 and 3. Since 7 is greater than 3, swap them: 5 3 7 9 2 6
Compare 7 and 9. Since 7 is smaller than 9, no swap is needed: 5 3 7 9 2 6
Compare 9 and 2. Since 9 is greater than 2, swap them: 5 3 7 2 9 6
Compare 9 and 6. Since 9 is greater than 6, swap them: 5 3 7 2 6 9
After the first pass, the largest number (9) has moved to the end of the list. The order of the data will be: 5 3 7 2 6 9During the first pass of the Bubble Sort algorithm on the given set of numbers (7, 5, 3, 9, 2, 6), adjacent pairs of numbers are compared and swapped if necessary. After the first pass, the largest number "bubbles" up to the end of the list. In this case, 9 is the largest number, and it moves to the end. The resulting order after the first pass is 5, 3, 7, 2, 6, 9. Bubble Sort continues with subsequent passes until the entire list is sorted in ascending order.

which of the following is true about the difference between a worm and a virus?
A worm is a standalone malware program that can replicate itself and spread across networks without requiring a host program or user action, while a virus is a malware program that attaches itself to a legitimate program or file and requires a host program or user action to replicate and spread.
There are several differences between a worm and a virus:
Method of propagation: A worm is a standalone program that can spread independently over a network or through various communication channels, such as email or instant messaging. In contrast, a virus needs a host file or program to attach itself and requires user action, such as opening an infected file or executing a program, to spread.
Self-replication: Worms have the ability to self-replicate and spread automatically, often without the user's knowledge. Viruses, on the other hand, rely on the user's actions to propagate by infecting files or programs and spreading when those files or programs are shared or executed.
Payload and behavior: Worms primarily focus on spreading themselves and creating network-based disruptions. They often exploit vulnerabilities in operating systems or network protocols. Viruses, on the other hand, typically have a specific payload or malicious code attached to them.
Detection and removal: Due to their self-replicating and spreading nature, worms are usually easier to detect and remove. Antivirus software and network security measures can often identify and block known worm signatures. Viruses can be more challenging to detect and remove, as they can hide within legitimate files or programs and may require specialized antivirus tools or manual removal procedures.
Overall, the key differences lie in their methods of propagation, self-replication abilities, payloads, and impact on systems. Understanding these distinctions helps in implementing appropriate security measures and response strategies to mitigate the risks associated with worms and viruses.
