The Nth Fibonacci number is defined as the sum of the two previous Fibonacci numbers where the
0th and 1st Fibonacci numbers are defined as 1. What is the maximum size of the stack when this
function is called with the argument 5? What is the maximum size of stack when the function is called with n when n >= 4 (expression in term of n)
int Fibonacci( int n ) {
return (n <= 1) ? 1 : Fibonacci( n - 1 ) + Fibonacci( n - 2 );
}
Answers
The given recursive function calculates the nth Fibonacci number and The maximum size of the stack when this function is called with the argument 5 is 8.
To determine the maximum size of the stack when this function is called with the argument 5, we must start with the base case. For n=0 and n=1, the function returns 1 directly, without invoking itself. The stack size remains 1 in these cases. For n=2, the function calls itself twice, with n=1 and n=0, respectively. The stack size is 3 in this case. For n=3, the function calls itself with n=2 and n=1. The stack size is 4. For n=4, the function calls itself with n=3 and n=2. The maximum stack size is 5, since this is the deepest we have gone into the recursion tree. For n=5, the function calls itself with n=4 and n=3.
The maximum stack size is 8, since we go to a depth of 3 in both the left and right sub-trees before reaching the base case. Therefore, the maximum size of the stack when this function is called with the argument 5 is 8. When the function is called with n when n >= 4, the maximum size of the stack can be expressed in terms of n as follows:
stack_size(n) = stack_size(n-1) + stack_size(n-2) + 1 where stack_size(0) = stack_size(1) = 1
This recurrence relation arises because the function makes two recursive calls, with arguments n-1 and n-2, respectively. Each of these calls spawns its own sub-tree of recursive calls, and the size of each sub-tree is given by the same recurrence relation. The "+1" term accounts for the initial call to the function itself.

An integer, numElements, which represents the number of elements in a vector called propertiesList.
To create a new vector, secondList, that is a shifted-left version of propertiesList with the first element moved to the end, you can use a loop.
Here's a simple way to accomplish this using a loop:
Initialize an empty vector, secondList, with the same size as propertiesList.Use a for loop to iterate through the elements of propertiesList, starting from index 1 to the end.In each iteration of the loop, copy the current element from propertiesList to secondList at the previous index (i.e., secondList[i - 1] = propertiesList[i]).After the loop is complete, copy the first element of propertiesList to the end of secondList (i.e., secondList[numElements - 1] = propertiesList[0]).This will result in the updated properties as required, where original properties 21 1582 1019 will become updated properties 1582 1019 21.For such more questions on integer

(10 points) For EM algorithm for GMM, please show how to use Bayes rule to drive \( \tau_{k}^{i} \) in closed-form expression.
Answers
The closed-form expression for \( \tau_{k}^{i} \) in the EM algorithm for GMM is derived using Bayes rule, representing the probability that observation \( x_{i} \) belongs to the kth component. By dividing the likelihood and prior by the sum of all such terms, we arrive at the desired expression.
In EM algorithm for GMM, Bayes rule can be used to derive the closed-form expression for \( \tau_{k}^{i} \).
The expression is as follows:$$\tau_{k}^{i} = \frac{p_{k}(x_{i}|\theta_{k})\pi_{k}}{\sum_{j=1}^{K}p_{j}(x_{i}|\theta_{j})\pi_{j}}$$where, \(x_{i}\) is the ith observation, \(\theta_{k}\) represents the parameters of the kth component, \(p_{k}(x_{i}|\theta_{k})\) represents the probability of \(x_{i}\) belonging to the kth component, and \(\pi_{k}\) is the mixing proportion of the kth component.
To derive this expression using Bayes rule, we can use the following steps:1. Using Bayes rule, we can write the posterior probability of the kth component as:$$p_{k}(\theta_{k}|x_{i}) = \frac{p_{k}(x_{i}|\theta_{k})\pi_{k}}{\sum_{j=1}^{K}p_{j}(x_{i}|\theta_{j})\pi_{j}}$$2.
Since we are interested in the probability that the ith observation belongs to the kth component, we can simplify the above expression as:$$p_{k}(x_{i}|\theta_{k})\pi_{k} = \tau_{k}^{i}p_{k}(\theta_{k}|x_{i})\sum_{j=1}^{K}\tau_{j}^{i}p_{j}(x_{i}|\theta_{j})$$3. Dividing both sides of the above equation by \(p_{i}(x_{i})\), we get:$$\tau_{k}^{i} = \frac{p_{k}(x_{i}|\theta_{k})\pi_{k}}{\sum_{j=1}^{K}p_{j}(x_{i}|\theta_{j})\pi_{j}}$$This is the closed-form expression for \( \tau_{k}^{i} \) that we were looking for.

Answers
Optional attributes and relationships become columns that allow for nullable values.
This means that a row in the database table can have a null value for that particular attribute or relationship. Nullable columns are important because not all entities will have values for all attributes or relationships. For example, a customer entity may not have a value for the "fax number" attribute, or a product entity may not have a value for the "supplier" relationship. Without nullable columns, these entities would not be able to be properly represented in the database. Nullable columns also allow for flexibility in data entry and querying, as they allow for the possibility of missing or unknown data.

The scope of a Prolog variable is Group of answer choices The head of the rule The body of the rule The entire rule All rules with the same name
Answers
The scope of a Prolog variable refers to the part of the program where the variable can be accessed or used. In Prolog, variables can have different scopes depending on their placement in the rule.
1. The scope of a variable in Prolog is determined by its placement in the rule.
2. The scope of a variable is limited to the rule in which it is defined. This means that a variable defined in the head of a rule can only be used within that rule's body.
3. Variables defined in the body of a rule have a scope limited to that specific rule. They cannot be accessed or used outside of that rule.
4. Variables defined in the entire rule have a scope that encompasses the entire rule. They can be accessed and used in both the head and body of the rule.
5. Variables with the same name in different rules are considered separate variables and have independent scopes. They can be accessed and used within their respective rules, but not in other rules.
For example, let's consider the following Prolog rule:
```
parent(john, jim).
parent(jim, ann).
```
In this case, the variable `john` and `jim` have a scope limited to the rule in which they are defined. They cannot be accessed or used outside of these rules.
In summary, the scope of a Prolog variable is determined by its placement in the rule, with variables defined in the head, body, or entire rule having different scopes. Variables with the same name in different rules have independent scopes. Understanding the scope of variables is crucial in writing correct and efficient Prolog programs.

[b] fully homomorphic encryption can do additions and multiplications on cipher text. [c] honey encryption has a lower complexity than symmetric encryption. [d] honey encryption ensures an attacker will get a random-looking plaintext using a wrong key.
Answers
The correct statement among the given options is [b] fully homomorphic encryption can do additions and multiplications on cipher text.
Homomorphic encryption refers to a type of encryption where certain operations can be performed on the encrypted data without having to decrypt it first. This provides an additional layer of security to the data as it can be processed without the risk of being exposed. Fully homomorphic encryption (FHE) takes it a step further and allows for both additions and multiplications to be performed on the encrypted data. This is a significant improvement over previous forms of homomorphic encryption, which only allowed for limited computations based on plaintext. Honey encryption, on the other hand, is a type of encryption that uses decoy data to mislead attackers. It does not have a lower complexity than symmetric encryption, as it is designed to add an extra layer of security to the existing encryption.
In summary, the correct answer to the given question is option [b]. Fully homomorphic encryption is capable of performing both additions and multiplications on cipher text.
