Write a recursive method called sumTo that accepts an integer parameter n and returns a real number representing the sum of the first n reciprocals. In other words, sumTo(n) returns (1 1/2 1/3 1/4 ... 1/n). For example, sumTo(2) should return 1.5. The method should return 0.0 if it is passed the value 0 and throw an IllegalArgumentException if it is passed a value less than 0.

Consider the following two data structures for storing several million words.
I. An array of words, not in any particular order
II. An array of words, sorted in alphabetical order
Which of the following statements most accurately describes the time needed for operations on these data structures?
A. Finding the first word in alphabetical order is faster in I than in II.
B. Inserting a word is faster in II than in I.
C. Finding a given word is faster in II than in I.
D. Finding the longest word is faster in II than in I.
Answer:
The correct answer is C.
Explanation:
Finding a given word requires the search operation. The search operation is faster in a sorted array compared to an unsorted array. In a sorted array the binary search method is used which runs on logarithmic time while in an unsorted array, there's no other way than linear search which takes O(n) time on the worst case where the required word is not in the array.
The statement which most accurately describes the time needed for operations on these data structures is: C. Finding a given word is faster in II than in I.
What is a binary search?Binary search can be defined as an efficient algorithm that is designed and developed for searching an element (information) from a sorted list of data, especially by using the run-time complexity of Ο(log n)
Note: n is the total number of elements.
In Computer science, Binary search typically applies the principles of divide and conquer. Thus, to perform a binary search on an array, the array must first be sorted in an alphabetical or ascending order.
In conclusion, the statement which most accurately describes the time needed for operations on these data structures is that, finding a given word is faster in data structure II than in I.

. Create an abstract Dollar class with two integer attributes, both of which are non-public (Python programmers - it is understood that there is nothing private in Python but try to not access the attributes directly from outside the classes). The int attributes will represent whole part (or currency note value) and fractional part (or currency coin value) such that 100 fractional parts equals 1 whole part.
Answer:
Explanation:
The following code is written in Java. It creates the abstract dollar class that has two instance variables for the dollars and the coins that are passed as arguments. The test output can be seen in the picture attached below.

You work part-time at a computer repair store. You are building a new computer. A customer has purchased two serial ATA (SATA) hard drives for his computer. In addition, he would like you to add an extra eSATA port that he can use for external drives. In
Install an eSATA expansion card in the computer to add an extra eSATA port for the customer's external drives.
To fulfill the customer's request of adding an extra eSATA port for external drives, you can install an eSATA expansion card in the computer. This expansion card will provide the necessary connectivity for the customer to connect eSATA devices, such as external hard drives, to the computer.
First, ensure that the computer has an available PCIe slot where the expansion card can be inserted. Open the computer case and locate an empty PCIe slot, typically identified by its size and the number of pins. Carefully align the expansion card with the slot and firmly insert it, ensuring that it is properly seated.
Next, connect the power supply cable of the expansion card, if required. Some expansion cards may require additional power to operate properly, and this is typically provided through a dedicated power connector on the card itself.
Once the card is securely installed, connect the eSATA port cable to the expansion card. The cable should be included with the expansion card or can be purchased separately if needed.
Connect one end of the cable to the eSATA port on the expansion card and the other end to the desired location on the computer case where the customer can easily access it.
After all connections are made, close the computer case, ensuring that it is properly secured. Power on the computer and install any necessary drivers or software for the expansion card, following the instructions provided by the manufacturer.
With the eSATA expansion card installed and configured, the customer will now have an additional eSATA port available on their computer, allowing them to connect external drives and enjoy fast data transfer speeds.

The value at index position x in the first array corresponds to the value at the
same index position in the second array. Initialize the array in (a) with hardcoded random sales values. Using the arrays in (a) and (b) above, write Java
statements to determine and display the highest sales value, and the month in
which it occurred. Use the JOptionPane class to display the output.
Sure! Here's a Java code snippet that demonstrates how to find the highest sales value and its corresponding month using two arrays and display the output using the JOptionPane class:
import javax.swing.JOptionPane;
public class SalesAnalyzer {
public static void main(String[] args) {
// Array with hardcoded random sales values
double[] sales = {1500.0, 2000.0, 1800.0, 2200.0, 1900.0};
// Array with corresponding months
String[] months = {"January", "February", "March", "April", "May"};
double maxSales = sales[0];
int maxIndex = 0;
// Find the highest sales value and its index
for (int i = 1; i < sales.length; i++) {
if (sales[i] > maxSales) {
maxSales = sales[i];
maxIndex = i;
}
}
// Display the highest sales value and its corresponding month
String output = "The highest sales value is $" + maxSales +
" and it occurred in " + months[maxIndex] + ".";
JOptionPane.showMessageDialog(null, output);
}
}
Explanation:
The code defines two arrays: sales for the hardcoded random sales values and months for the corresponding months.The variables maxSales and maxIndex are initialized with the first element of the sales array.A loop is used to iterate through the sales array starting from the second element. It compares each value with the current maxSales value and updates maxSales and maxIndex if a higher value is found.After the loop, the output message is constructed using the highest sales value (maxSales) and its corresponding month from the months array (months[maxIndex]). Finally, the JOptionPane.showMessageDialog() method is used to display the output in a dialog box.When you run the program, it will display a dialog box showing the highest sales value and the month in which it occurred based on the provided arrays.

Increase the value of cell c30 by 15%
To increase the value of cell C30 by 15%, you can multiply the current value of C30 by 1.15.
To increase the value of cell C30 by 15%, you can follow these steps. First, multiply the current value of C30 by 0.15 to calculate 15% of the value. Then, add this calculated amount to the current value of C30. This can be expressed as C30 + (C30 * 0.15). For example, if the current value of C30 is 100, you would perform the calculation 100 + (100 * 0.15) to get the increased value. In this case, the result would be 115. This method ensures that the value in cell C30 is increased by 15% while retaining the existing value. Adjusting calculations accordingly based on the desired value and spreadsheet software used will allow you to increase the value of cell C30 by 15%.For more such questions on Cell C30:

Create another method: getFactorial(int num) that calculates a Product of same numbers, that Sum does for summing them up. (1,2,3 ... num) Make sure you use FOR loop in it, and make sure that you pass a number such as 4, or 5, or 6, or 7 that you get from a Scanner, and then send it as a parameter while calling getFactorial(...) method from main().
Answer:
The program in Java is as follows;
import java.util.*;
public class Main{
public static int getFactorial(int num){
int fact = 1;
for(int i =1;i<=num;i++){
fact*=i;
}
return fact;
}
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Number: ");
int num = input.nextInt();
System.out.println(num+"! = "+getFactorial(num)); }}
Explanation:
The method begins here
public static int getFactorial(int num){
This initializes the factorial to 1
int fact = 1;
This iterates through each digit of the number
for(int i =1;i<=num;i++){
Each of the digits are then multiplied together
fact*=i; }
This returns the calculated factorial
return fact; }
The main begins here
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
This prompts the user for number
System.out.print("Number: ");
This gets input from the user
int num = input.nextInt();
This passes the number to the function and also print the factorial
System.out.println(num+"! = "+getFactorial(num)); }}

Implement a class Clock whose getHours and getMinutes methods return the current time at your location. (Call java.time.LocalTime.now().toString() and extract the time from that string.) Also provide a getTime method that returns a string with the hours and minutes by calling the getHours and getMinutes methods. Provide a subclass WorldClock whose constructor accepts a time offset. For example, if you live in California, a new WorldClock(3) should show the time in New York, three time zones ahead. Which methods did you override
Answer:
Explanation:
The following code was written in Java. It uses the LocalTime import to detect the current time. Then it creates a getHours, getMinutes, and getTime method to correctly print out only the hours and minutes in a simple format. Then it does the same for the WorldClock subclass which takes in the time offset as an int parameter and adds that to the hours in your own timezone.
class Clock {
public String getHours() {
String hours = java.time.LocalTime.now().toString().substring(0,2);
return hours;
}
public String getMinutes() {
String min = java.time.LocalTime.now().toString().substring(3,5);
return min;
}
public String getTime() {
String time = getHours() + ":" + getMinutes();
return time;
