Question 2 Numbers in binary can be represented as arrays of single bits, e.g. the number 35 in decimal in binary is 100011, and the corresponding array is [1,0,0,0,1,1]. This question is about multiplying integers in terms of these binary arrays. That is, given two arrays of bits representing two integers, produce a new array that is the corresponding binary representation of the two integers multiplied. For instance, given [1,0,0,0,1,1] and [1,1,0], which are 35 and 6 respectively, an algorithm should produce [1,1,0,1,0,0,1,0], which is 210, the product of 35 and 6. We can assume that the integers have binary representations both of length N. This can be always be achieved by padding the beginning of the array with extra zeroes. In the example above the two input arrays can be made [1,0,0,0,1,1] and [0,0,0,1,1,0]. The first pseudocode function we consider adds together two N-length arrays: function Add (A, B, N) if(N==0): return empty array C1=new array(N+1) of zeroes C2=new array(N+1) of zeroes i=N-1 while i >= 0 C1[i+1] =A[i]+B[i]+C2[i+1] mod 2 if(A[i]+B[i]+C2 [i+1]<2): C2[i]=0 else: C2[i]=1 i-i-1 if(C2[0]==0): C3=new array(N) of zeroes for 0 < i <= N C3[i-1]=C1[i] return C3 else: C1[8]=1 return C1 end function (a) What is the worst-case time complexity of the function Add in terms of the length of the arrays N? Explain the worst-case inputs arrays are of length N (2 marks), use Theta notation (1 mark) and briefly explain your reasoning (4 marks). (7 marks)

The game's implementation is exemplary because it addresses the tension issue and the ghost character's actions issue raised by the creator in an efficient way that makes the game more interesting and challenging for Pac-Man.

(a) The game’s creator's tension idea was to have the monsters surround Pac-Man, however, he felt that it would be too stressful for Pac-Man to be continually surrounded and hunted down.

The game’s implementation solved this problem by having the ghosts leave Pac-Man alone for some time.

The ghosts scatter, giving Pac-Man an opportunity to collect dots and power pellets.

The ghosts start to chase Pac-Man once again after a set period, keeping the game balanced and exciting until it concludes.

(b) The game’s implementation addressed the creator's concerns about each ghost having its own characteristics by having each ghost behave in a unique way.

The red ghost, Blinky, pursues Pac-Man more aggressively than the others. Pinky, the pink ghost, seeks Pac-Man’s position, but she doesn’t pursue him as fiercely as Blinky.

Inky, the blue ghost, tries to capture Pac-Man by ambushing him, while Clyde, the orange ghost, goes in random directions.

The ghosts' unique actions make the game more interesting and provide Pac-Man with a range of challenges to overcome, which include identifying the ghosts' unique actions.

(a) Given that angle C = 30°, length of side c = 5.5 cm and length of side a = 4 cm, we can use the Law of Sines to find the value of angle A. The Law of Sines states that the ratio of the sine of an angle to the length of the opposite side is equal for all angles in a triangle.

sin(A)/a = sin(C)/c

Substituting the given values, we get:

sin(A)/4 = sin(30°)/5.5

sin(A) = 4 * sin(30°) / 5.5

sin(A) = 4 * 0.5 / 5.5

sin(A) = 4/11

A = sin^-1(4/11)

A = 41.2°

Therefore, the value of angle A is 41.2°.

(b) A triangle has sides a = 2, b = 3, and angle C = 40°. We can use the Law of Cosines to find the value of side c. The Law of Cosines states that the square of the length of a side in a triangle is equal to the sum of the squares of the lengths of the other two sides minus twice the product of those sides and the cosine of the angle between them.

c^2 = a^2 + b^2 - 2ab * cos(C)

Substituting the given values, we get:

c^2 = 2^2 + 3^2 - 2 * 2 * 3 * cos(40°)

c^2 = 13 - 12 * cos(40°)

c^2 = 13 - 12 * 0.766

c^2 = 1.236

c = 1.11 cm

Therefore, the length of side c is 1.11 cm.

The problem is as follows: given five variables a, b, c, d, e of type int which already have values and a variable counter of type int, give counter a value based on the number of variables among a, b, c, d and e that have nonzero values. That means counter will always get a number between 0 and 5, inclusive.

For example, if a, b, c, d, and e are all 0, then counter will be 0. On the other hand, if a and d are 0 but b, c, e have nonzero values, then counter will get the new value 3.The solution to the given problem can be achieved by using several simple if statements.

The algorithm for the same can be written as follows:Algorithm:Step 1: Initialize counter to 0.Step 2: If a is nonzero, increment the counter by 1.Step 3: If b is nonzero, increment the counter by 1.Step 4: If c is nonzero, increment the counter by 1.Step 5: If d is nonzero, increment the counter by 1.Step 6: If e is nonzero, increment the counter by 1.Step 7: End of the algorithm.After the execution of the above algorithm, the value of the variable counter will be equal to the number of variables among a, b, c, d, and e that have nonzero values.For example, if a = 0, b = 2, c = 0, d = 4, and e = 0, then counter will be equal to 2.

Object-oriented design metrics play a crucial role in assessing the testability of an object-oriented (OO) system by providing quantifiable measures that reflect the system's characteristics.

Cyclomatic Complexity: Cyclomatic complexity measures the complexity of a method or function by counting the number of independent paths through its code. High cyclomatic complexity indicates increased complexity and potentially more test cases required to achieve thorough test coverage. For example, if the `Account` class has a method like `processTransaction()`, a high cyclomatic complexity might suggest the need for extensive testing to cover different transaction scenarios.

Coupling: Coupling measures the interdependencies between classes. High coupling can make testing more challenging as changes in one class may impact other classes, requiring additional tests to validate the behavior. For instance, if the `Account` class tightly depends on the `Transaction` class, modifying the `Transaction` class might require additional tests on the `Account` class to ensure its functionality is unaffected.

Cohesion: Cohesion measures the degree to which the responsibilities of a class are related and focused. High cohesion indicates that a class has a well-defined purpose, making it easier to test in isolation. If the `Customer` class handles only customer-related operations and does not include unrelated functionality, it would exhibit high cohesion and be easier to test.

Dependency Injection (DI): DI is a design pattern that enables loose coupling and testability by injecting dependencies into a class rather than letting the class create or manage them. By using DI, testability is improved as dependencies can be replaced with mock objects or stubs during testing, allowing for isolated unit tests. For example, if the `Account` class relies on an external `TransactionLogger` class, using DI to inject the logger would make it easier to substitute it with a test-specific logger during unit tests.

These are just a few examples of object-oriented design metrics that can influence the testability of an OO system. By analyzing these metrics, testers and developers can identify potential challenges, design flaws, or areas requiring additional test coverage. This knowledge can guide the development of effective testing strategies and ensure the system's testability, leading to more reliable and maintainable software.

Here's an example of how you can define the `InvalidRadiusException` class in Java as a custom exception class:

```java

public class InvalidRadiusException extends Exception {

   private double radius;

   public InvalidRadiusException(double radius) {

       super("Invalid radius: " + radius);

       this.radius = radius;

   }

   public double getRadius() {

       return radius;

   }

}

```

In this example:

- The `InvalidRadiusException` class extends the built-in `Exception` class, making it a custom exception class.

- The class has a private instance variable `radius` to store the invalid radius value.

- The constructor takes the invalid radius as a parameter and uses the `super` keyword to call the constructor of the `Exception` class with a custom error message.

- The `getRadius` method is provided to retrieve the invalid radius value.

You can use this custom exception class `InvalidRadiusException` to handle cases where a negative radius is encountered. For example:

```java

public class CircleWithCustomException {

   private double radius;

   public CircleWithCustomException(double radius) throws InvalidRadiusException {

       if (radius < 0) {

           throw new InvalidRadiusException(radius);

       }

       this.radius = radius;

   }

   // Rest of the class implementation...

}

```

In the `CircleWithCustomException` class, we use the `InvalidRadiusException` by throwing it when a negative radius is provided to the constructor. This allows you to handle such cases and provide custom error messages or perform specific actions when a negative radius is encountered.

However, in the worst case, when n is a power of 2, the dominant factor affecting the running time is the number of recursive calls, which is linearly proportional to n. Therefore, the worst case big O running time of the given function simplifies to O(n).

The worst case big O running time of the given function can be expressed as O(n).

In the function, the input size n is divided by 2 three times recursively, resulting in a binary tree-like structure with a total of 2^k nodes at level k. Each level performs a constant amount of work with the for loop iterating from 0 to n.

Considering the worst case scenario, where n is a power of 2 (i.e., n = 2^k), the number of recursive calls at each level will be 2^0, 2^1, 2^2, ..., 2^(k-1) respectively. The total number of recursive calls will be the sum of these values, which can be approximated to n.

Additionally, the for loop at each level performs a constant amount of work relative to n. Since the depth of the recursion tree is log2(n), the overall running time can be expressed as O(n log n).

Effective writing is an essential component of communication. A good writer is one who can convey their thoughts, ideas, or messages in a clear and concise manner. Among the 20 rules of effective writing discussed in the book, "The Elements of Style" by William Strunk Jr. and E.B. White, the following are the four rules that I believe are the most important:

1. Use active voice - Writing in active voice creates sentences that are clear and direct. Active voice is where the subject of the sentence is the doer of the action, while passive voice is where the subject is acted upon. The use of active voice makes the sentence easy to read and understand.
2. Omit needless words - It is crucial to avoid redundancy and eliminate unnecessary words or phrases. The inclusion of unnecessary words or phrases can make the writing dull and boring. Concise writing can convey a message in fewer words and in a more interesting manner.
3. Write in short sentences - Writing in short sentences makes the text easier to read and comprehend. Short sentences help to break down complex ideas into simple ones and keep the reader engaged in the text.
4. Be clear and specific - Being clear and specific is essential in effective writing. A writer must be precise and to the point while conveying their ideas. Specific details provide more clarity and depth to the message.

In conclusion, effective writing involves clear and concise language that is easy to understand. Writing in active voice, omitting needless words, using short sentences, and being clear and specific are the four most important rules to follow when striving for effective writing. These rules can help writers create compelling content that is engaging and informative.

Cyclic Redundancy Check (CRC) is a type of error-detecting code that identifies any alterations to the original data. It is widely used to check data integrity. The algorithm creates a checksum that is appended to the end of the message. To check if data is corrupted, the checksum is recomputed and compared to the transmitted checksum. If they are equal, then the data is free of errors. If they don't match, then the data has been corrupted.What are CRC bits?The cyclic redundancy check (CRC) is a technique used to detect errors in data transmission. A CRC is generated and sent with the data. The receiver calculates a new CRC and compares it to the one that was sent. If they match, then there are no errors. If they don't match, then an error has occurred.The generator polynomial G is multiplied by the data payload D and divided by 2 to the power of r, where r is the length of the generator polynomial.

For (1), The correct answer is option 1) can be explicitly overridden. For(2), The correct answer is option 1) compile. For (3), The correct answer is option 2) an operator function. For (4), The correct answer is option 3) out_of_range. For (5), The correct answer is option 4) neither an `out_of_range` nor a `range_error`.

1) When a function is defined as virtual, all functions in the hierarchy of classes with the same signature marked as virtual can be explicitly overridden.

When a function is declared as virtual in the base class, it allows derived classes to provide their own implementation of the function. If a derived class wants to override a virtual function from the base class, it can do so explicitly by using the "override" keyword in C++. This informs the compiler that the derived class is intentionally overriding the virtual function.

The correct answer is option 1) can be explicitly overridden.

2) In the inclusion approach, we compile the definition file separately.

In the inclusion approach, the implementation of a class is split into two parts: the class declaration in a header file (.h or .hpp) and the class definition in a separate source file (.cpp). When using the inclusion approach, we compile the class definition file separately from the other source files that use the class. The class declaration (header file) is included in the source files that need to access the class.

The correct answer is option 1) compile.

3) To overload an operator for a class, we need an operator function.

Operator overloading allows us to redefine the behavior of operators for user-defined classes. To overload an operator, we need to define a special member function called the operator function. This function specifies how the operator should behave when applied to objects of the class.

The correct answer is option 2) an operator function.

4) If the given data should be between x and y and we try to use data outside this range, the exception thrown is 3) out_of_range.

The C++ standard library provides the exception class `std::out_of_range` to handle situations where an index or value is outside the valid range. This exception is typically thrown when accessing elements of a container, such as an array or a vector, beyond its valid bounds.

The correct answer is option 3) out_of_range.

5) When the returned value of a function is outside a specified range, neither an `out_of_range` nor a `range_error` is thrown.

Neither `out_of_range` nor `range_error` exceptions are thrown automatically by the C++ standard library when a returned value of a function is outside a specified range. It is the responsibility of the programmer to handle and validate the returned value if a specific range needs to be enforced.

The correct answer is option 4) neither an `out_of_range` nor a `range_error`.

To write a Prolog program for answering queries about your family tree, you need to define the facts and rules representing the relationships in your family.

The program includes facts about your family members. For example, female(your_mother) states that your mother is a female.

The rules define relationships and answer the queries:

mother(X) rule defines that X is your mother if X is a female.

count_sisters(N) rule uses the findall/3 predicate to find all sisters and calculates the length to get the count of sisters.

has_brother rule states that you have a brother if there exists any individual who is defined as a brother.

To use the program, you can consult it in a Prolog interpreter and then pose queries:

Query A: mother(X). will give you the answer for "Who is your mother?" by unifying X with the name of your mother.

Query B: count_sisters(N). will provide the count of your sisters by unifying N with the number of sisters you have.

Query C: has_brother. will give a simple "yes" or "no" answer to the question "Do you have any brother?".

Note: Please replace the placeholders (your_mother, your_sister1, your_sister2, your_brother) with the actual names or identifiers of your family members.

The height of a projectile can be calculated using a MATLAB function called "height" that determines the height of a ball at a given time.

To calculate the height of a projectile, we can use the following formula:

h(t) = v0 * t * sin(θ) - (1/2) * g * t^2

where:

- h(t) is the height of the ball at time t

- v0 is the initial velocity of the ball

- θ is the launch angle of the ball

- g is the acceleration due to gravity (approximately 9.8 m/s^2)

The function "height" can be defined in MATLAB as follows:

```matlab

function h = height(t, v0, theta)

   g = 9.8; % acceleration due to gravity

   h = v0 * t * sin(theta) - (1/2) * g * t^2;

end

```

In this function, we pass three input arguments: t (time), v0 (initial velocity), and theta (launch angle). The function calculates and returns the height of the ball at the given time.

To use this function, you can call it with the desired values for t, v0, and theta. For example, to calculate the height of the ball at time t = 2 seconds, with an initial velocity of v0 = 20 m/s and a launch angle of theta = 45 degrees, you can write:

```matlab

h = height(2, 20, pi/4);

```

This will assign the calculated height to the variable "h". You can modify the input values according to your specific scenario.

No, using the L2 norm and the L1 norm for regularization purposes in deep neural networks is not equivalent. The L2 norm (squared) penalizes larger weights more heavily than the L1 norm.

This is because the L2 norm squares the individual weight values, which amplifies the impact of large weights on the regularization term. Consequently, the L2 regularization encourages the model to have smaller weights overall.

On the other hand, the L1 norm (absolute values) does not square the weight values and treats all weights equally. It promotes sparsity by encouraging some weights to become exactly zero. This can lead to a more interpretable and compact model.

In summary, the L2 norm and L1 norm regularization have different effects on the weights of a deep neural network. The L2 norm favors smaller weights, while the L1 norm promotes sparsity. Therefore, they are not equivalent in terms of regularization purposes.

The L2 norm and the L1 norm have different effects on the regularization of deep neural networks. The L2 norm, which squares the weight values, penalizes larger weights more strongly, encouraging the model to have smaller weights overall. In contrast, the L1 norm, which takes the absolute values of the weights, promotes sparsity by encouraging some weights to become exactly zero. This leads to a more interpretable and compact model. Thus, the L2 norm and the L1 norm have distinct regularization properties, making them suitable for different scenarios. Therefore, they are not equivalent in terms of regularization purposes in deep neural networks.
