Task 4) Write a Java program to count all the non duplicate objects in a priority queue Input: \( 3,100,12,10,3,13,100,77 \) Output: \( 4(12,10,13,77 \) is not repeated)
Answers
Here's a Java program that counts all the non-duplicate objects in a priority queue:
```java
import java.util.*;
public class NonDuplicateCount {
public static void main(String[] args) {
PriorityQueue<Integer> priorityQueue = new PriorityQueue<>();
// Add elements to the priority queue
priorityQueue.add(3);
priorityQueue.add(100);
priorityQueue.add(12);
priorityQueue.add(10);
priorityQueue.add(3);
priorityQueue.add(13);
priorityQueue.add(100);
priorityQueue.add(77);
int nonDuplicateCount = countNonDuplicates(priorityQueue);
System.out.println("Number of non-duplicate objects: " + nonDuplicateCount);
}
public static int countNonDuplicates(PriorityQueue<Integer> priorityQueue) {
HashMap<Integer, Integer> countMap = new HashMap<>();
// Count the frequency of each element in the priority queue
for (Integer element : priorityQueue) {
countMap.put(element, countMap.getOrDefault(element, 0) + 1);
}
int nonDuplicateCount = 0;
for (Integer element : countMap.keySet()) {
if (countMap.get(element) == 1) {
nonDuplicateCount++;
}
}
return nonDuplicateCount;
}
}
```
This program uses a `PriorityQueue` to store the input elements. The `countNonDuplicates` method takes the priority queue as input, counts the frequency of each element using a `HashMap`, and then counts the number of elements with a frequency of 1, which represents the non-duplicate objects. The result is then printed to the console.
When you run the program, it will output: `Number of non-duplicate objects: 4`, indicating that there are four non-duplicate objects in the priority queue.

Which of the following touch screen gestures should she use to zoom in on the screen? Stretch Stretch Pinch Pinch Drag and slide Drag and slide Press and hold Press and hold
Answers
Reagan should use the pinch gesture to zoom in on the screen. Reagan is working on her homework on a touchscreen laptop which has Windows® 10 operating system.
Reagan wants to zoom in on the screen to see the text of a document better. To zoom in on the screen, Reagan can use the pinch gesture. Pinch is a touch screen gesture used to zoom in or out of a page, an image, or to minimize or maximize a window. The pinch gesture is made by placing two fingers on the screen and then moving them closer together or farther apart. For instance, to zoom in, Reagan should place her thumb and forefinger on the screen and then move them apart.
On the other hand, to zoom out, Reagan can place her thumb and forefinger on the screen and then move them closer together. Stretch is a similar gesture to the pinch but is made by moving the fingers apart from each other, thereby making the page or image bigger. This gesture is often used in conjunction with drag and slide to move the screen in different directions.
Drag and slide involves moving one or more fingers on the screen in any direction to move a page or an image in the same direction. Lastly, Press and hold is a gesture that is made by placing a finger on the screen and holding it there for a few seconds. It can be used to access a menu or activate an app. In conclusion, Reagan should use the pinch gesture to zoom in on the screen.

If its sales rise, its Select one: a. net income based on absorption costing will go up more than its net income based on variable costing. b. net income based on variable costing will go up more than its net income based on absorption costing. c. per unit variable costs will rise. d. fixed costs will also rise.
Answers
The correct answer is: b. net income based on variable costing will go up more than its net income based on absorption costing.
In absorption costing, fixed manufacturing overhead costs are allocated to units produced, resulting in a portion of fixed costs being included in the cost of each unit. As sales rise, more units are sold, and the allocated fixed costs are spread over a larger number of units, reducing the impact on net income. In variable costing, fixed manufacturing overhead costs are treated as a period expense and not allocated to units produced. As a result, changes in sales volume have a direct impact on net income, as variable costs are directly linked to the number of units sold. when sales rise, net income based on variable costing will increase more significantly than net income based on absorption costing.

why does sql does not support the conditional execution of procedures that are typically supported by a programming language using the general format
Answers
SQL is a popular programming language used for managing relational databases. It provides a set of commands to perform various operations on the database. One of the limitations of SQL is that it does not support the conditional execution of procedures, unlike programming languages like Java and C++.
Procedures are a set of SQL statements that are executed sequentially to perform a specific task. In programming languages, it is possible to conditionally execute a procedure based on certain conditions using if-else statements. However, SQL does not support such conditional execution of procedures. The reason for this limitation is that SQL is primarily designed for data manipulation and not for general-purpose programming. SQL is optimized for handling large amounts of data and performing complex queries, and adding programming constructs like if-else statements can significantly impact its performance. Moreover, SQL is a declarative language, which means that it focuses on defining what needs to be done rather than how it needs to be done. The conditional execution of procedures is more suited for imperative programming languages, where the focus is on defining the step-by-step instructions to perform a task.
In conclusion, SQL does not support the conditional execution of procedures due to its focus on data manipulation and declarative nature. While programming languages like Java and C++ provide the ability to conditionally execute procedures, adding such features to SQL can impact its performance and go against its design principles.

Answers
A mapping from the plane to the plane is a mathematical function that associates points on a plane with corresponding points on the same plane, enabling various transformations and geometric operations.
In mathematics, a mapping from the plane to the plane, also known as a function or transformation, involves assigning each point on a given plane to a corresponding point on the same plane. This process allows for various types of transformations to be applied, such as translations, rotations, reflections, scalings, and more.
To better understand this concept, consider a simple example of a translation mapping. Suppose we have a function that takes a point (x, y) on a plane and produces a new point (x + a, y + b), where 'a' and 'b' are constant values representing the amount of translation in the x and y directions, respectively. This mapping shifts each point on the plane by the same amount 'a' horizontally and 'b' vertically.
Similarly, other types of mappings can be defined to perform different transformations. For instance, a rotation mapping can rotate each point on the plane around a fixed point by a certain angle. A scaling mapping can expand or contract the distances between points on the plane. A reflection mapping can create a mirror image of the points across a specified line or axis.
Mappings from the plane to the plane are fundamental in various areas of mathematics, such as geometry, linear algebra, and complex analysis. They provide a way to study and analyze transformations and their properties in relation to points and shapes on the plane.
By utilizing mappings, mathematicians and scientists can understand how different operations and transformations affect geometric figures, solve equations involving variables in the plane, model real-world phenomena, and make predictions based on mathematical principles.
In summary, a mapping from the plane to the plane refers to a function or transformation that associates points on a given plane with corresponding points on the same plane. It enables various transformations to be applied, providing insights into the relationships and properties of geometric figures and mathematical models.
