Answer:
The function in C++ is as follows:
int isSorted(int ar[], int n){
if ([tex]n == 1[/tex] || [tex]n == 0[/tex]){
return 1;}
if ([tex]ar[n - 1][/tex] < [tex]ar[n - 2][/tex]){
return 0;}
return isSorted(ar, n - 1);}
Explanation:
This defines the function
int isSorted(int ar[], int n){
This represents the base case; n = 1 or 0 will return 1 (i.e. the array is sorted)
if ([tex]n == 1[/tex] || [tex]n == 0[/tex]){
return 1;}
This checks if the current element is less than the previous array element; If yes, the array is not sorted
if ([tex]ar[n - 1][/tex] < [tex]ar[n - 2][/tex]){
return 0;}
This calls the function, recursively
return isSorted(ar, n - 1);
}
Write a java program that reads a list of integers and outputs those integers in reverse. The input begins with an integer indicating the number of integers that follow. For coding simplicity, follow each output integer by a comma, including the last one. Assume that the list will always contain fewer than 20 integers.
Ex: If the input is:
5 2 4 6 8 10
the output is:
10,8,6,4,2,
To achieve the above, first read the integers into an array. Then output the array in reverse.
Answer:
Explanation:
using namespace std;
#include <iostream>
int Go()
{
int N;
int A[20];
cout << " How many integers do you have ??? :>";
cin >> N;
if (N>20) { N=20; }
for (int iLoop=0; iLoop<N; iLoop++)
{
cout << "Input integer # " << (iLoop+1) << " :>";
cin >> A[iLoop];
}
for (int iLoop=N-1; iLoop>=0; iLoop--)
{
cout << A[iLoop] << " ";
}
cout << endl;
}
int main()
{
Go();
}
A Java program that reads a list of integers and outputs them in reverse is written as,
import java.util.Scanner;
public class ReverseList {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
// Read the number of integers
int numIntegers = scnr.nextInt();
// Create an array to store the integers
int[] integers = new int[numIntegers];
// Read the integers into the array
for (int i = 0; i < numIntegers; i++) {
integers[i] = scnr.nextInt();
}
// Output the integers in reverse order
for (int i = numIntegers - 1; i >= 0; i--) {
System.out.print(integers[i]);
// Add comma unless it's the last integer
if (i > 0) {
System.out.print(",");
}
}
System.out.println(); // Add a new line at the end
}
}
Given that,
Write a Java program that reads a list of integers and outputs those integers in reverse.
Here, The input begins with an integer indicating the number of integers that follow.
For coding simplicity, follow each output integer by a comma, including the last one.
So, A Java program that reads a list of integers and outputs them in reverse:
import java.util.Scanner;
public class ReverseList {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
// Read the number of integers
int numIntegers = scnr.nextInt();
// Create an array to store the integers
int[] integers = new int[numIntegers];
// Read the integers into the array
for (int i = 0; i < numIntegers; i++) {
integers[i] = scnr.nextInt();
}
// Output the integers in reverse order
for (int i = numIntegers - 1; i >= 0; i--) {
System.out.print(integers[i]);
// Add comma unless it's the last integer
if (i > 0) {
System.out.print(",");
}
}
System.out.println(); // Add a new line at the end
}
}

Fill in multiple blanks for [x], [y], [z]. Consider a given TCP connection between host A and host B. Host B has received all from A all bytes up to and including byte number 2000. Suppose host A then sends three segments to host B back-to-back. The first, second and third segments contain 50, 600 and 100 bytes of user data respectively. In the first segment, the sequence number is 2001, the source port number is 80, and the destination port number is 12000. If the first segment, then third segment, then second segment arrive at host B in that order, consider the acknowledgment sent by B in response to receiving the third segment. What is the acknowledgement number [x], source port number [y] and destination port number [z] of that acknowledgement
What order? (function templates) Define a generic function called CheckOrder() that checks if four items are in ascending, neither, or descending order. The function should return -1 if the items are in ascending order, 0 if the items are unordered, and 1 if the items are in descending order. The program reads four items from input and outputs if the items are ordered. The items can be different types, including integers, strings, characters, or doubles. Ex. If the input is:
Answer:
Explanation:
The following code was written in Java and creates the generic class to allow you to compare any type of data structure. Three different test cases were used using both integers and strings. The first is an ascending list of integers, the second is a descending list of integers, and the third is an unordered list of strings. The output can be seen in the attached image below.
import java.util.Scanner;
class Brainly {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Order: " + checkOrder(10, 22, 51, 53));
System.out.println("Order: " + checkOrder(55, 44, 33, 22));
System.out.println("Order: " + checkOrder("John", " Gabriel", "Daniela", "Zendaya"));
}
public static <E extends Comparable<E>> int checkOrder(E var1, E var2, E var3, E var4) {
E prevVar = var1;
if (var2.compareTo(prevVar) > 0) {
prevVar = var2;

/* From the information provided, For now will consider the name of table as TRIPGUIDES*/
/*In all the answers below, the syntax is based on Oracle SQL. In case of usage of other database queries, answer may vary to some extent*/
1.
Select R.Reservation_ID, R.Trip_ID , C.Customer_Num,C.Last_Name from Reservation R, Customer C where C.Customer_Num=R.Customer_Num ORDER BY C.Last_Name
/*idea is to select the join the two tables by comparing customer_id field in two tables as it is the only field which is common and then print the desired result later ordering by last name to get the results in sorted order*/
2.
Select R.Reservation_ID, R.Trip_ID , R.NUM_PERSONS from Reservation R, Customer C where C.Customer_Num=R.Customer_Num and C.LAST_NAME='Goff' and C.FIRST_NAME='Ryan'
/*Here, the explaination will be similar to the first query. Choose the desired columns from the tables, and join the two tables by equating the common field

In the above question, we first selected the trip name from trip table. To put the condition we first make sure that all the three tables are connected properly. In order to do so, we have equated Guide_nums in guide and tripguides. and also equated trip_id in tripguides and trip. Then we equated names from guide tables and type from trip table for the desired results.

*/
/*The comparison of dates in SQL depends on the format in which they are stored. In the upper case if the
dates are stored in the format as YYYY-MM-DD, then the above query mentioned will work. In case dates are stored in the form of a string then the following query will work.

Complete reverse() method that returns a new character array containing all contents in the parameter reversed.
Ex: If the input array is:
['a', 'b', 'c']
then the returned array will be:
['c', 'b', 'a']
import java.util.*;
public class LabProgram {
// This method reverses contents of input argument arr.
public static char[] reverse(char[] arr) {
/* Type your code here. */
}
public static void main(String[] args) {
char [] ch = {'a','b','c'};
System.out.println(reverse(ch)); // Should print cba
}
}

For the following 4-bit operation, assuming these register are ONLY 4-bits in size, which status flags are on after performing the following operation? Assume 2's complement representation. 1010+0110
a) с
b) Z
c) N
Answer:
All flags are On ( c, z , N )
Explanation:
Given data:
4-bit operation
Assuming 2's complement representation
Determine status flags that are on after performing 1010+0110
1 1
1 0 1 0
0 1 1 0
1 0 0 0 0
we will carry bit = 1 over
hence C = 1
given that: carry in = carry out there will be zero ( 0 ) overflow
hence V = 0
also Z = 1
But the most significant bit is N = 1
Preserving confidentiality, integrity, and availability is a restatement of the concern over interruption, interception, modification, and fabrication.
i. Briefly explain the 4 attacks: interruption, interception, modification, and fabrication.
ii. How do the first three security concepts relate to these four attacks
Answer and Explanation:
I and II answered
Interruption: interruption occurs when network is tampered with or communication between systems in a network is obstructed for illegitimate purposes.
Interception: interception occurs when data sent between systems is intercepted such that the message sent to another system is seen by an unauthorized user before it reaches destination. Interception violates confidentiality of a message.
Modification: modification occurs when data sent from a system to another system on the network is altered by an authorized user before it reaches it's destination. Modification attacks violate integrity, confidentiality and authenticity of a message.
Fabrication: fabrication occurs when an unauthorized user poses as a valid user and sends a fake message to a system in the network. Fabrication violates confidentiality, integrity and authenticity.

Answer: Availability
Explanation:
In C language
In a main function declare an array of 1000 ints. Fill up the array with random numbers that represent the rolls of a die.
That means values from 1 to 6. Write a loop that will count how many times each of the values appears in the array of 1000 die rolls.
Use an array of 6 elements to keep track of the counts, as opposed to 6 individual variables.
Print out how many times each value appears in the array. 1 occurs XXX times 2 occurs XXX times
Hint: If you find yourself repeating the same line of code you need to use a loop. If you declare several variables that are almost the same, maybe you need to use an array. count1, count2, count3, count4, … is wrong. Make an array and use the elements of the array as counters. Output the results using a loop with one printf statement. This gets more important when we are rolling 2 dice.
Answer:
The program in C is as follows:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main(){
int dice [1000];
int count [6]={0};
srand(time(0));
for (int i = 0; i < 1000; i++) {
dice[i] = (rand() %(6)) + 1;
count[dice[i]-1]++;
}
for (int i = 0; i < 6; i++) {
printf("%d %s %d %s",(i+1)," occurs ",count[i]," times");
printf("\n");
}
return 0;
}
Explanation:
This declares an array that hold each outcome
int dice [1000];
This declares an array that holds the count of each outcome
int count [6]={0};
This lets the program generate different random numbers
srand(time(0));
This loop is repeated 1000 times
for (int i = 0; i < 1000; i++) {
This generates an outcome between 1 and 6 (inclusive)
dice[i] = (rand() %(6)) + 1;
This counts the occurrence of each outcome
count[dice[i]-1]++; }
The following prints the occurrence of each outcome
for (int i = 0; i < 6; i++) {
printf("%d %s %d %s",(i+1)," occurs ",count[i]," times");
printf("\n"); }
Select the correct statement(s) regarding decentralized (distributed) access control on a LAN. a. no centralized access process exists, and therefore each connected station has the responsibility for controlling its access b. data collisions are possible, therefore mechanisms such as CDMA/CD are required c. when a data collision occurs, the nearest station detecting the collision transmits a jamming signal d. all of the above are correct
Answer: D. all of the above are correct
Explanation:
The correct statements regarding the decentralized (distributed) access control on a LAN include:
• no centralized access process exists, and therefore each connected station has the responsibility for controlling its access
• data collisions are possible, therefore mechanisms such as CDMA/CD are required
• when a data collision occurs, the nearest station detecting the collision transmits a jamming signal.
Therefore, the correct option is all of the above.
Should you remove jewelry, pens, and other metal objects before entering the magnetic resonance (MR) environment even if the equipment is not in use?
Answer:
Yes you should

Explanation:
The code provided worked for the most part, it had some gramatical errors in when printing out the information as well as repeated values. I fixed and reorganized the printed information so that it is well formatted. The only thing that was missing from the code was the input validation to make sure that no negative values were passed.

In confirmatory visualization Group of answer choices Users expect to see a certain pattern in the data Users confirm the quality of data visualization Users don't know what they are looking for Users typically look for anomaly in the data
Answer: Users expect to see a certain pattern in the data
Explanation:
Confirmatory Data Analysis occurs when the evidence is being evaluated through the use of traditional statistical tools like confidence, significance, and inference.
In this case, there's an hypothesis and the aim is to determine if the hypothesis is true. In this case, we want to know if a particular pattern on the data visualization conforms to what we have.

The function receives two arguments. The first argument is the string from which the occurrence is to be checked. The second argument is the substring to be checked.
In this case, the string is "Get Well Soon!" while the substring is "Well"
Starting from 0, the substring "Well" can be found to begin at position 4 of the string "Get Well Soon!".
Therefore, the function strpos("Get Well Soon!", "Well") will return 4.
Then, with the echo statement, which is used for printing, value 4 will be printed as output of the code.
A recursive method may call other methods, including calling itself. Creating a recursive method can be accomplished in two steps. 1. Write the base case -- Every recursive method must have a case that returns a value or exits from the method without performing a recursive call. That case is called the base case. A programmer may write that part of the method first, and then lest. There may be multiple base cases.Complete the recursive method that returns the exponent of a given number. For e.g. given the number 5 and the exponent 3 (53) the method returns 125. Note: any number to the zero power is 1. Note: Do not code for the example. Your method must work for all given parameters! Use this as your method header: public static int raiseToPower(int base, int exponent)
Answer:
Explanation:
The following code is written in Java. It creates the raiseToPower method that takes in two int parameters. It then uses recursion to calculate the value of the first parameter raised to the power of the second parameter. Three test cases have been provided in the main method of the program and the output can be seen in the attached image below.
class Brainly {
public static void main(String[] args) {
System.out.println("Base 5, Exponent 3: " + raiseToPower(5,3));
System.out.println("Base 2, Exponent 7: " + raiseToPower(2,7));
System.out.println("Base 5, Exponent 9: " + raiseToPower(5,9));
}
public static int raiseToPower(int base, int exponent) {
if (exponent == 0) {
return 1;
} else if (exponent == 1) {
return base;
} else {
return (base * raiseToPower(base, exponent-1));
}
}
}

I have a list of happiness and six explanatory vars.
exp_vars = ['Happiness', 'LogGDP', 'Support', 'Life', 'Freedom', 'Generosity', 'Corruption']
1. Define a variable called explanatory_vars that contains the list of the 6 key explanatory variables
2. Define a variable called plot_vars that contains Happiness and each of the explanatory variables. (Hint: recall that you can concatenate Python lists using the addition (+) operator.)
3. Using sns.pairplot, make a pairwise scatterplot for the WHR data frame over the variables of interest, namely the plot_vars. To add additional information, set the hue option to reflect the year of each data point, so that trends over time might become apparent. It will also be useful to include the options dropna=True and palette='Blues'.

3. Circular, array-backed queue In the following class, which you are to complete, the backing array will be created and populated with Nones in the __init__ method, and the head and tail indexes set to sentinel values (you shouldn't need to modify __init__). Enqueuing and Dequeuing items will take place at the tail and head, with tail and head tracking the position of the most recently enqueued item and that of the next item to dequeue, respectively. To simplify testing, your implementation should make sure that when dequeuing an item its slot in the array is reset to None, and when the queue is emptied its head and tail attributes should be set to -1.

Add (total) all the number in the list (below) using a for loop, but skip over the number at index 3.
numbers = [10,20,30,40,50,60,100]
Answer:
The program in Python is as follows:
numbers = [10,20,30,40,50,60,100]
total = 0
for i in range(len(numbers)):
if i != 3:
total+=numbers[i]
print(total)
Explanation:
This initializes the list
numbers = [10,20,30,40,50,60,100]
Set total to 0
total = 0
This iterates through numbers
for i in range(len(numbers)):
This ensures that the index 3, are not added
if i != 3:
total+=numbers[i]
Print the calculated sum
print(total)

{
Scanner scnr = new Scanner(System.in);//defining a Scanner class object
String firstString;//defining a String variable
String secondString; //defining a String variable
firstString = scnr.next();//input value
secondString = scnr.next();//input value
if (firstString.compareTo(secondString) < 0)//use if to compare sting value
System.out.println(firstString + " " + secondString);//print sting value
