Given the scikit's digits dataset, write a program to convert the feature matrix into a sparse matrix and then reduce the dimensionality of the feature matrix. You can use scikit's Truncated Singular Value Decomposition (TSVD).

To implement binary search in descending order, we just have to change the comparison logic to `midvalue` which we use in ascending order.

Here is the code below:

public class BinarySearch2 {    public static void main(String[] args) {        int[] numbers = { -9, -1, 2, 3, 4, 15, 99 };        int value

ToSearch = 4;    

  int index = binary

Search2(numbers, valueToSearch);

      if (index == -1) {            System.out.

print ln (Element not found!");  

     } else {  System.out.

print ln("Element found at index " + index);        }    }    public static int binary

Search2(int[] input, int value) {        int low = 0;        int high = input.length - 1;  

    while (low <= high) {            int mid = (low + high) / 2;        

   if (input[mid] < value) {                high = mid - 1;      

    } else if (input[mid] > value) {                low = mid + 1;  

         } else {                return mid;            }        }        return -1;

  }}

The output will be: Element found at index 4

Thus, the final implementation of binary search in descending order will be achieved in the same way as in the case of binary search in ascending order, but only by changing the comparison operator for descending order.

JavaScript was originally designed with a procedural programming paradigm in mind, along with elements of functional programming.

JavaScript was originally designed with a primarily procedural programming paradigm in mind, along with elements of functional programming.

The initial design of JavaScript, known as LiveScript, was influenced by languages such as C and Perl, which are primarily procedural in nature.

However, as JavaScript evolved, it incorporated features from other programming paradigms as well. It adopted object-oriented programming (OOP) principles, adding support for objects and prototypes.

Additionally, JavaScript introduced functional programming concepts, including higher-order functions, closures, and the ability to treat functions as first-class objects.

These additions expanded the programming capabilities of JavaScript, allowing developers to use a combination of procedural, object-oriented, and functional styles based on the requirements of their applications.

So the final hexadecimal form of (-90.5625)10 in single precision (32-bit) IEEE Floating Point notation is:1 10000101 10101010010000000000000 = (D5555000)16Therefore, the answer is D5555000.

To convert to single precision (32-bit) IEEE Floating Point notation, express the given decimal number -90.5625 in binary form. Then determine the sign, exponent, and mantissa and finally convert to hexadecimal form.The sign of the given number is negative (-) since it is less than 0. The magnitude of the number is 90.5625. Convert the magnitude of the given number to binary form:(90)10 = (1011010)2(0.5625)10 = (0.1001)2Therefore, (-90.5625)10 = (1101010.1001)2

Step 2: The leftmost bit of the binary representation is 1, which means that we need to shift the decimal point to the left to place the binary point directly after the first bit, so that the number is in the form (1.M)2 * 2^E.If we shift the decimal point to the left 6 times, then the binary representation becomes:1.10101010010000000000000 x 2^(6)

Step 3: The exponent E = (127 + 6)10 = (133)10, which is (10000101)2 in binary.

So the final form is:1 10000101 10101010010000000000000

Step 4:To obtain the hexadecimal form, group the binary number as follows:1   10000101   10101010010000000000000 | sign   exponent  mantissa The sign bit is 1 since the number is negative.

Hence the sign bit is represented by the leftmost bit.The exponent bits are 10000101 which equals (85)10 and (55)16.

The provided Kotlin code defines a MergeSort class that implements the merge sort algorithm. It extends a Merge class, which provides the necessary helper methods. The mergeSort method recursively divides and merges the input array to return a sorted array.

To create a public class named `MergeSort` in Kotlin, you can use the following code:

```
class MergeSort : Merge() {
   fun mergeSort(array: IntArray): IntArray {
       if (array.size <= 1) {
           return array
       }
       val mid = array.size / 2
       val left = array.copyOfRange(0, mid)
       val right = array.copyOfRange(mid, array.size)
       return merge(mergeSort(left), mergeSort(right))
   }
}
```

In this code, we define the `MergeSort` class which extends the `Merge` class. The `Merge` class provides the `merge` method and the `copyOfRange` method that we need.

The `mergeSort` method is our implementation of the merge sort algorithm. It takes an `IntArray` as input and returns a sorted `IntArray`. Inside the `mergeSort` method, we have a base case where if the size of the array is less than or equal to 1, we simply return the array as it is already sorted.

If the size of the array is greater than 1, we divide the array into two halves using the `copyOfRange` method. We recursively call the `mergeSort` method on the left and right halves to sort them.

Finally, we use the `merge` method from the `Merge` class to merge the sorted left and right halves and return the sorted array.

Here's an example usage of the `MergeSort` class:

```
val array = intArrayOf(5, 2, 9, 1, 7)
val mergeSort = MergeSort()
val sortedArray = mergeSort.mergeSort(array)
println(sortedArray.contentToString()) // Output: [1, 2, 5, 7, 9]
```

In this example, we create an `IntArray` called `array` with some unsorted values. We then create an instance of the `MergeSort` class and call the `mergeSort` method on the `array`. The resulting sorted array is stored in the `sortedArray` variable, and we print it out using `println`.

The output will be `[1, 2, 5, 7, 9]`, which is the sorted version of the input array `[5, 2, 9, 1, 7]`.

At Execution Point A, the value of EAX is 758 (decimal).

The code snippet begins by moving the offset of the idArray into the ESI register. The offset represents the memory location of the idArray.

Next, the code moves the value at the memory location [ESI+2*TYPE idArray] into the EAX register. Here, 2*TYPE idArray calculates the offset to the third element in the idArray.

Since each element in the idArray is a DWORD (4 bytes), the offset to the third element would be 2*4 = 8 bytes.

The value at that memory location is 758 (decimal), so it is stored in EAX at Execution Point A.

In this code snippet, the ESI register is used to store the offset of the idArray, and the EAX register is used to store the value of the third element of the idArray. The OFFSET operator is used to get the memory location of the idArray, and the TYPE operator is used to calculate the size of each element in the idArray.

By adding the calculated offset to the base address of the idArray, we can access the desired element in the array. In this case, the third element has an offset of 8 bytes from the base address.

Understanding the sizes of the data types and the calculation of memory offsets is crucial for correctly accessing and manipulating data in assembly language programming.

c The interval containing 99% of the values of the coefficient of restitution is approximately (0.5836918, 0.6587932).

a we can calculate the confidence interval using the formula:

CI = x ± Z * (s / sqrt(n))

Since we want a 99% confidence interval, the Z-value for a 99% confidence level is approximately 2.576.

CI = 0.6212425 ± 2.576 * (0.0145757 / sqrt(40))

= 0.6212425 ± 2.576 * 0.0023101

Therefore, the 99% confidence interval on the mean coefficient of restitution is approximately (0.6152944, 0.6271906).

b Since we still want a 99% prediction interval, we use the same Z-value of approximately 2.576.

PI = 0.6212425 ± 2.576 * (0.0145757 * sqrt(1 + 1/40))

= 0.6212425 ± 2.576 * 0.0145882

To forecast temperature in Washington, DC with categorical variables and seasonality, follow steps such as data exploration, dummy variable conversion, model fitting, forecast generation, and performance evaluation.

To develop a multiple regression model with categorical variables that incorporates seasonality for forecasting the temperature in Washington, DC, using the data for the years 1999 and 2000, you can follow these steps:

Import the data from the Excel file "washingtondcweather.xlsx" into a statistical software program like R or Python. Explore the data to understand its structure, variables, and patterns. Look for any missing values or outliers that may need to be addressed.

Identify the categorical variables related to seasonality in the dataset. For example, you may have variables like "Month" or "Season" that indicate the time of year.

Convert the categorical variables into dummy variables. This involves creating binary variables for each category. For example, if you have a "Season" variable with categories "Spring," "Summer," "Fall," and "Winter," you would create four dummy variables (e.g., "Spring_dummy," "Summer_dummy," etc.).

Select other relevant independent variables that may influence temperature, such as humidity, precipitation, or wind speed.

Split the data into a training set (years 1999 and 2000) and a test set (year 2001). The training set will be used to build the regression model, and the test set will be used to evaluate its forecasting performance.

Use the training set to fit the multiple regression model, including the dummy variables for seasonality and other independent variables. The model equation will look something like this:

Temperature = β0 + β1 * Season_dummy1 + β2 * Season_dummy2 + ... + βn * Independent_variable1 + ...

Here, β0, β1, β2, ..., βn are the coefficients estimated by the regression model.

Assess the model's goodness of fit using statistical metrics like R-squared and adjusted R-squared. These metrics indicate the proportion of variance in the temperature that is explained by the independent variables.

Once the model is validated on the training set, use it to generate forecasts for the next nine months of the year 2001. These forecasts will provide estimated temperatures for each month.

Compare the forecasted temperatures with the actual observations for the year 2001 using appropriate error metrics like mean absolute error (MAE) or root mean squared error (RMSE). These metrics quantify the accuracy of the forecasts.

Analyze the results and assess the model's performance. If the forecasts closely match the actual observations, the model is considered reliable. Otherwise, you may need to revise the model by including additional variables or adjusting the existing ones.

Finally, interpret the coefficients of the regression model to understand the impact of each variable on the temperature in Washington, DC. For example, positive coefficients suggest that an increase in the variable leads to a higher temperature, while negative coefficients indicate the opposite.

Remember, this is a general framework for developing a multiple regression model with categorical variables that incorporate seasonality. The specific implementation and analysis may vary depending on the software you use and the characteristics of the dataset.

The given program will recursively look through the provided directory for files and directories that match the given criteria.

If a file or directory is found that matches the given criteria, the path to that file should be printed out. The possible criteria are:

1. char *name: If name is NULL, then this restriction does not apply. Otherwise, before printing out any found file or directory, you must first check that the file or directory's name exactly matches the provided name. You can find the name of a found file or directory through the d_name field in the struct dirent * returned by readdir.

2. int min_depth: If min_depth is -1, then this restriction does not apply. Otherwise, before printing out any found file or directory, you must first check if the current search is at least min_depth directories deep. You should keep track of your current depth through a recursive parameter. The initial depth of the files directly inside the provided directory is 0.

3. int max_depth: If max_depth is -1, then this restriction does not apply. Otherwise, before printing out any found file or directory, you must first check if the current search is at most max_depth directories deep. You should keep track of your current depth through a recursive parameter. The initial depth of the files directly inside the provided directory is 0.

You can implement the supp_q7 function in the following way to fulfill all the given criteria:

Ultimate goals of a distributed computing system:

1) Connecting Users and Resources .

2) Transparency .

3) Openness .

4) Scalable.

The four important goals that should be met for an efficient distributed computing system are as follows:

1. Connecting Users and Resources:

The main goal of a distributed system is to make it easy for users to access remote resources and to share them with others in a controlled way.

It is cheaper to le a printer be shared by several users than buying and maintaining printers for each user.

Collaborating and exchanging information can be made easier by connecting users and resource.

2. Transparency:

It is important for a distributed system to hide the location of its process and resource. A distributed system that can portray itself as a single system is said to be transparent.

The various transparencies need to be considered are access, location, migration, relocation, replication, concurrency, failure and persistence.

Aiming for distributed transparency should be considered along with performance issues.

3. Openness:

Openness is an important goal of distributed system in which it offers services according to standard rules that describe the syntax and semantics of those services.

Open distributed system must be flexible making it easy to configure and add new components without affecting existing components.

An open distributed system must also be extensible.

4. Scalable:

Scalability is one of the most important goals which are measured along three different dimensions.

First, a system can be scalable with respect to its size which can add more user and resources to a system.

Second, users and resources can be geographically apart.

Third, it is possible to manage even if many administrative organizations are spanned.
