Answer:

RecursiveCalls.backwardsAlphabet(startingLetter);

Explanation:

The statement that is needed is a single-line statement. Since the class RecursiveCalls is already in the same file we can simply use that class and call its function without making a new class object. Once we call that class' function we simply pass the variable startingLetter (which is already provided) as the sole parameter for the function in order for it to run and use the letter 'z' as the starting point.

RecursiveCalls.backwardsAlphabet(startingLetter);

2. Allow advanced users to customize a quick access bar to allow them to quickly access a more frequently used item.

Explanation:

1. Shortcut keys (Hot keys) provide a method for users to activate frequently used menu items in your menu system and to provide keyboard access to your application for those users who do not.

2. The Quick Access Toolbar (or QAT) allows you to create an easily accessible group of shortcuts to the tools you use most frequently.

sergeinik [125]

Answer:

offline backup solution

Explanation:

In such a scenario, the best option would be an offline backup solution. This is basically a local and offline server that holds all of the flight record data that the cloud platform has. This offline backup server would be updated frequently so that the data is always up to date. These servers would be owned by the aviation company and would be a secondary solution for the company in case that the cloud platform fails or the company cannot connect to the cloud service for whatever reason. Being offline allows the company to access the database regardless of internet connectivity.

9.6 Code Practice: Question 1

worty [1.4K]

Answer:

import java.util.Random;
import java.util.Arrays;
public class Main {
public static void main(String[] args) {
int n = 10;
int [] myArray = new int[n];
buildArray(myArray, n);
System.out.println(Arrays.toString(myArray));
}
public static void buildArray(int[] arr, int n){
for(int i=0; i < arr.length; i++){
Random rand = new Random();
arr[i] = rand.nextInt(90) +10;
}
}
}

Explanation:

Firstly, create a method buildArray that take two inputs, an array and an array size (Line 12). In the method, use random nextInt method to repeatedly generate a two digit random number within a for loop that will loop over array size number of times (Line 13-15). The expression rand.nextInt(90) + 10 will generate digits between 10 - 99.

In the main program, call the build array method by using an array and array size as input arguments (Line 8). At last, print the array after calling the buildArray method (Line 9).

Suppose that the data mining task is to cluster points (with (x, y) representing location) into three clusters, where the points

solong [7]

Answer:

Explanation:

K- is the working procedure:

It takes n no. of predefined cluster as input and data points.

It also randomly initiate n centers of the clusters.

In this case the initial centers are given.

Steps you can follow

Step 1. Find distance of each data points from each centers.

Step 2. Assign each data point to the cluster with whose center is nearest to this data point.

Step 3. After assigning all data points calculate center of the cluster by taking mean of data points in cluster.

repeat above steps until the center in previous iteration and next iteration become same.

A1(4,8), A2(2, 4), A3(1, 7), B1(5, 4), B2(5,7), B3(6, 6), C1(3, 7), C2(7,8)

Centers are X1=A1, X2=B1, X3=C1

A1 will be assigned to cluster1, B1 will be assigned to cluster2 ,C1 will be assigned to cluster3.

Go through the attachment for the solution.
