Sorting algorithms are a method of ordering a set of data in a specific pattern. The sequence of items in a data set may influence the speed of various sorting algorithms.
Each sorting algorithm operates differently and takes a different amount of time to sort. Sorting algorithms can be broken down into two categories: internal and external sort. Quick sort, Bubble sort, Selection sort.
Insertion sort are examples of internal sorting algorithms. The order of the elements in an array, linked list, or any data structure is affected by the running time of an internal sorting algorithm. Internal sorting algorithms, such as Selection Sort, Quick Sort.

Notes: 1- Late home works will not be accepted. 2- Due date is 15/5/2022 at 10:00 Am. 3- Submit your source code file and write your name as a comment inside the file. Work: Write a program that will read a Knowledge Base (KB) that will consists of many sentences formatted in the CNF format, and a query (one sentence) also in the CNF format from a text file. You should ask the user to enter the name of the file at the beginning of your program and then you should read that file and print its content on the screen. Then your code should try to entail the query from the KB and outputs whether it can be entailed or not. The format of the input file will be having the KB on a line and the query on the next line. The file may contain more than one request and it will be listed as: (A v B)^(C v B)^(-C) A (A v B)^(C v B)^(Dv-C) AB Output should be : KB: (Av ~B)^(C v B)^(-C) query: A KB: (A v B)^(Cv^B)^(Dv-C) query: A B Yes, A can be entailed. No, A^B can't be entailed.
The program reads a Knowledge Base (KB) and a query in CNF format from a file, displays the KB and query, and determines if the query can be entailed using resolution refutation.
Can the given query be entailed from the Knowledge Base using resolution refutation?The given task requires writing a program that reads a Knowledge Base (KB) from a text file.
The KB consists of multiple sentences in Conjunctive Normal Form (CNF) format, followed by a query sentence in CNF format.
The program should prompt the user to enter the name of the file, read its contents, and display them on the screen.
Subsequently, the program should attempt to determine whether the query can be entailed from the KB and provide an output indicating the result.
To accomplish this, the program can follow these steps:
Ask the user to input the filename.Read the file and extract the KB and query sentences.Print the extracted KB and query on the screen.Implement an algorithm to determine if the query can be entailed from the KB. Output whether the query can be entailed or not.For the entailment check, one possible approach is to use resolution refutation.
This involves creating a resolution proof by repeatedly applying the resolution rule to derive new clauses and check for a contradiction.
If a contradiction is found, it means the query can be entailed from the KB.
In the given example, the first line of the file represents the KB and the second line represents the query: A.
By applying resolution refutation, it can be determined that A can be entailed from the KB, as there is no contradiction in the resulting clauses.
Therefore, the output would be "Yes, A can be entailed."
By implementing a program that follows these steps, it becomes possible to read a file containing a KB and a query, display the KB and query on the screen, and determine whether the query can be entailed from the KB using resolution refutation.

(a) (2 points) When computing the reward for an MDP, what does a higher discount factor mean? (b) (2 points) What is the difference between the V function (VH) and the Q function (Q+) of a policy ? (c
(a) When computing the reward for an MDP, a higher discount factor means that future rewards are given more weight or importance.
(b) The V function estimates the value of being in a state under a given policy, while the Q function estimates the value of taking a specific action in a state under a given policy.
The discount factor in MDP (Markov Decision Process) is a value between 0 and 1 that represents the importance of future rewards in the decision-making process. A higher discount factor places more emphasis on future rewards and less on immediate rewards. When computing the reward for an MDP, a higher discount factor means that future rewards are more important, and the agent is more likely to make decisions that lead to long-term gain, even if it requires sacrificing short-term gain.
The V function (VH) and the Q function (Q+) are two common ways of representing the expected reward in reinforcement learning. The V function represents the expected reward for a state in a given policy. In other words, it estimates how good it is to be in a particular state under a particular policy. On the other hand, the Q function represents the expected reward for taking an action in a particular state under a given policy. In other words, it estimates how good it is to take a specific action in a particular state under a particular policy.
In summary, the main difference between the V function and the Q function is that the V function estimates the value of being in a state, whereas the Q function estimates the value of taking a particular action in a state.

he SAT problem is the central problem for the complexity class NP.concerning the satisfiability (or not) of a given formula in conjunctive normal form (CNF) Φ = Λο, (15 marks) where each clause C, is the disjunction V of a number of literals over the set of logical variables {....,n}. Over the years, a huge number of approximation algorithms and heuristics have been developed to find high-quality assignments for CNF formulae, including our (derandomized) (8/7)-approximation algorithm for the special case of 3-CNF formulae (each clause has 3 literals, over 3 distinct variables). (a) Apply derandomization of conditional expectations to obtain a specific as signment to {:11, 12, 13, 14} which satisfies > 9x of the causes of formula shown below. Consider the variables in the order of increasing index, and show your workings. 0 = (1, VE, V13) (1 V 12 V 13) A (V12 V 1.) ( VF V.1) (, V13 V14) (11 Vis Vra) (12 V 13 Vra) (72V 13 Vf) (12 V 13 V 1.). (b) The algorithm for k= 3 above can be generalised to the 4-CNF case where each clause contains exactly 4 literals (over 4 distinct variables). i. What is the expected number of satisfied clauses of an initial 4-CNF formula with m clauses? ii. Consider an intermediate stage during conditional derandomization, where we have set a value for some variables and have some already satis- fied clauses, some already refuted clauses, and some unresolved clauses. Let' be the collection of not-yet-resolved clauses of sizes 1. 2.3 and 4. Suppose x; is the next variable to be assigned a bit value, and suppose that the set of clauses of that involve T, consist of: k clauses of size 1 which contain r, as the only remaining literal ki clauses of size 1 which contain i, as the only remaining literal k; clauses of size 2 which contain I k; clauses of size 2 which contain it kfclauses of size 3 which contain I k; clauses of size 3 which contain i, k clauses of size 4 which contains ki clauses of size 4 which contain
Derandomization of conditional expectations to obtain a specific assignment to {:11, 12, 13, 14} which satisfies > 9x of the clauses of the formula can be obtained by the following steps:
i) Let x_i denote the variable xi, then let us construct a bipartite graph G = (A, B, E), where each node in A is a variable x_i and each node in B is a clause C_i from the CNF formula Φ. Edges are drawn between a variable and clause node if the variable appears in the clause. Let E_i = {C_1, ..., C_ki} denote the set of clauses in which variable x_i appears.
Now we will run the following iterative process:- Choose a variable x_i that appears in the most number of unsatisfied clauses (satisfied clauses will be removed from E_i)- Flip a coin and set the value of x_i according to the result of the coin flip- Remove all clauses that are satisfied by this assignment- Remove x_i from all remaining clauses- Repeat until either all clauses are satisfied or no variable appears in any unsatisfied clause more than 9 times.
ii) Let X be the number of clauses that are satisfied by the algorithm. We can calculate the expected value of X as follows:E[X] = E[E[X|X_i]] = E[# of clauses that contain a satisfied variable] = \sum_{i=1}^{4} E[# of clauses of size i that contain a satisfied variable]
Therefore, we have:E[X] = (k1 + k2 + k3 + k4) * (1 - (3/4))^1 + (l1 + l2 + l3 + l4) * (1 - (3/4))^1 + (m1 + m2 + m3 + m4) * (1 - (3/4))^2 + (n1 + n2 + n3 + n4) * (1 - (3/4))^3where ki is the number of clauses of size i that contain a satisfied variable.

Suppose that X = (x1, . . . , xn) and X′= (x′1, . . . , x′n) are two sequences of n plaintext blocks. Let’s suppose X and X′ are encrypted in OFB mode using the same key and the same IV. Show how an adversary can compute X ⊕X′. Under what conditions in CBC mode can an adversary also potentially compute X ⊕X′? State this condition and show it.
In OFB (Output Feedback) mode, the keystream generated is independent of the plaintext that it is encrypting. In this mode, the plaintext is XORed with a keystream to obtain the ciphertext. If two plaintexts are encrypted using the same key and the same initialization vector (IV),
the keystream produced will also be the same. As a result, the XOR of these two ciphertexts would be equal to the XOR of their respective plaintexts, making it easy for an adversary to compute
`X ⊕ X′`.Assuming that the two plaintexts X and X′ have a length of `n` blocks, and their respective ciphertexts are `C = (c1, . . . , cn)` and `C′= (c′1, . . . , c′n)`. Let's say that the keystream generated by the OFB mode for both plaintexts is `K = (k1, . . . , kn)`.Since `C1 = X1 ⊕ K1` and `C′1 = X′1 ⊕ K1`, we have `X1 ⊕ X′1 = C1 ⊕ C′1`. Similarly, for any `i` between `2` and `n`, we have `Xi ⊕ X′i = Ci ⊕ C′i`. Thus, the adversary can compute `X ⊕ X′` by XORing the ciphertexts `C` and `C′`.In CBC (Cipher Block Chaining) mode, the ciphertext of a block is dependent on the plaintext of the previous block. The initialization vector is used to encrypt the first block and the output of each encryption operation is used as the input for the next operation. If two plaintexts are encrypted using the same key and the same IV,
the ciphertext of the first block will be the same for both plaintexts. If this happens, the XOR of the two ciphertexts will not be equal to the XOR of their respective plaintexts. However, an adversary can still compute `X ⊕ X′` if and only if the first block of the plaintext `X` is equal to the first block of the plaintext `X′`.

Write the missing code. public static void invertTree (Tree tree) { recursiveInvert(tree root); ) private static void recursiveInvert (TreeNode node) { //missing code
To invert a binary tree, you need to swap the left and right child nodes for each node in the tree recursively. Here's the missing code to complete the recursiveInvert method:
java
Copy code
private static void recursiveInvert(TreeNode node) {
if (node == null) {
return; // base case: empty node
}
// Swap the left and right child nodes
TreeNode temp = node.leftChild;
node.leftChild = node.rightChild;
node.rightChild = temp;
// Recursively invert the left and right subtrees
recursiveInvert(node.leftChild);
recursiveInvert(node.rightChild);
}
We first check if the current node is null. If it is, we simply return as there is no inversion to perform for an empty node.
Next, we swap the left and right child nodes of the current node using a temporary variable.
After swapping the child nodes, we recursively call the recursiveInvert method on the left and right child nodes. This will continue the inversion process for the entire tree, starting from the current node's children. By calling the invertTree method with the root of the tree, it will invert the entire binary tree in place.

These functions provide useful functionality for filtering and selecting student records based on major values. The `select By Major` function allows you to retrieve students enrolled in a specific major, while the `select Minus` function helps identify students who exclusively study one major and do not concentrate in another major. These operations can assist in managing and analyzing student data efficiently.
PART-1: The `select By Major` function takes a vector `VDB` containing student records and a string `major Value` representing a specific major. It populates the vector `v Solution` with student records from `VDB` that match the given major. It filters the records based on the `major` field and adds the matching records to `v Solution`.
PART-2: The `select Minus` function takes two vectors, `v1` and `v2`, representing different majors. It returns a new vector containing only the student records that appear in `v1` but not in `v2`. It compares the `id` field of the student records in both vectors and excludes any records that have a matching `id` in `v2`. The resulting vector represents the students who exclusively study the major in `v1` and do not concentrate in the major in `v2`.
PART-1: The `select By Major` function allows you to retrieve all the students who are enrolled in a specific major from the provided student database. It uses a linear search approach to iterate through each student record in `VDB` and checks if the `major` field matches the given `major Value`. If a match is found, the student record is added to the `v Solution` vector. This process continues until all the records in `VDB` have been examined. The resulting `v Solution` vector contains the student records that match the specified major.
PART-2: The `select Minus` function is designed to create a new vector that includes only the student records from `v1` (the first list) that do not appear in `v2` (the second list). It utilizes a nested loop approach to compare each student record in `v1` with every record in `v2`. The function checks if the `id` field of a student record in `v1` matches the `id` field of any student record in `v2`. If there is no match found, the student record from `v1` is considered exclusive and added to the resulting vector. Once all the records in `v1` have been compared with `v2`, the function returns the final vector containing the exclusive student records.

Explain the challenge imposed by guest OS to virtualization.
What is the common solution?
The challenge imposed by a guest operating system (OS) to virtualization is that it may be unaware that it is running in a virtualized environment. This lack of awareness can lead to conflicts.
When a guest OS runs within a virtual machine, it typically assumes it has direct access to the underlying hardware resources. However, in a virtualized environment, the guest OS must go through a hypervisor or virtualization layer, which abstracts and manages the hardware resources. This lack of direct access can cause compatibility issues, performance overhead, and security concerns. To overcome this challenge, virtualization techniques are employed. One common solution is hardware-assisted virtualization, which utilizes CPU features like Intel VT-x or AMD-V to provide hardware-level support for virtualization.

The total bits used by set and offset fields will be 6 bits (2^6 = 64).Tag bits will be remaining bits after subtracting the bits used by set and offset fields (20 - 6 - 6 = 8)So, the size of the tag field = 8 * 4 = 32 bits
b) Size of the set field In 2-way set associative cache mapping scheme, there will be 32 sets (64 blocks / 2 ways)In a memory address of 20 bits, 6 bits are used for offset and 8 bits for tag. So, the size of the set field = 20 - 6 - 8 = 6 bits
c) Size of the offset field The size of the offset field can be determined by the size of each block in the main memory. The size of each block in the main memory = 64 bytes = 2^6 bytes

The function can be used to print the contents of the binary tree in ascending order.
The infixprint() function in C++ for the bnode class is an in-order traversal of the binary tree. It is defined as follows:```void bnode::infixprint(void){if(left != NULL){left->infixprint();}cout << data << " ";if(right != NULL){right->infixprint();}}```The infixprint() function first checks if the left child of the current node exists. If it does, the function recursively calls itself on the left child. Then it prints the data of the current node, followed by a space. Finally, it checks if the right child of the current node exists. If it does, the function recursively calls itself on the right child.The function performs an in-order traversal of the binary tree since it first visits the left subtree of a node, then the node itself, and finally the right subtree of a node. The function can be used to print the contents of the binary tree in ascending order, assuming that the string data in each node is a numerical value or an alphabetical character.

When creating a virtual hard disk using Storage Spaces, and if there are six physical hard disks to choose from, you can choose the following resiliency types: Single parity, Dual parity, Two-way mirror, and Three-way mirror.
These resiliency types help protect the data stored on the virtual hard disk from failure or corruption, thereby ensuring its integrity and availability. The Single parity resiliency type creates a disk space with one data copy and one parity copy, protecting the data from a single disk failure.
Dual parity, on the other hand, creates a disk space with two parity copies and two data copies, thereby protecting the data from up to two disk failures.The Two-way mirror resiliency type mirrors the data across two hard disks to protect the data from a single disk failure.

8. What is the pattern form each type of numerical literal
this string can produce: /\d+\.?\d*|\.\d+/
a. How would you rewrite it without short cut key \d and
+
A pattern is used to describe a particular set of characters in a string. Here, we need to find out what pattern each type of numerical literal this string can produce.
First, let's understand the different terms in the string: `\d` - A shorthand character class that matches any digit. It is equivalent to [0-9]. `+` - Matches one or more of the preceding token. `.` - Matches any character except for a newline. `*` - Matches zero or more of the preceding token. `|` - Indicates an alternation. It matches either the expression before or after the pipe. So, the pattern `\d+\.?\d*` matches any number with or without a decimal point. Examples include 10, 3.141, 0.02, etc. The pattern `\.\d+` matches any decimal number starting with a decimal point. Examples include .5, .01, .2, etc. Here's the rewritten pattern without the shortcut key `\d` and `+`:```

How many times is numberOfStudents() called if main() calls numberOfStudents(9)?
public static void numberOfStudents(int num) {
if (num >= 10) {
System.out.println(num);
}
else {
System.out.print("Bye");
numberOfStudents(num+1);
}
}
The numberOfStudents() function will be called 10 times if main() calls numberOfStudents(9).
In the given code, the numberOfStudents() function is a recursive function that takes an integer parameter 'num'. The function first checks if 'num' is greater than or equal to 10. If it is, it prints the value of 'num'. Otherwise, it prints "Bye" and recursively calls itself with 'num+1'.
When main() calls numberOfStudents(9), the function is initially called with 'num' equal to 9. Since 9 is less than 10, it prints "Bye" and calls numberOfStudents(10). This process continues until 'num' reaches 10, at which point the function prints the value 10 and returns.
In total, the function is called 10 times: once for each value from 9 to 10. Each recursive call increments 'num' by 1 until it reaches 10, at which point the recursion stops.
Recursion is a programming technique where a function calls itself to solve a problem. In this case, the numberOfStudents() function is a recursive function that increments the value of 'num' by 1 with each recursive call until it reaches a base case (num >= 10). The function is called multiple times until the base case is met.
Recursion can be a powerful tool for solving certain types of problems, but it is important to ensure that there is a well-defined base case to avoid infinite recursion. In this example, the base case is when 'num' is greater than or equal to 10.
