Write an application that prompts a user for two integers and displays every integer between them. Display There are no integers between X and Y if there are no integers between the entered values. Make sure the program works regardless of which entered value is larger.
Answer:
x = int(input("Enter an integer: "))
y = int(input("Enter another integer: "))
if x > y:
for number in range(y+1, x):
print(number, end=" ")
elif y > x:
for number in range(x+1, y):
print(number, end=" ")
else:
print("There are no integers between {} and {}".format(x, y))
Explanation:
*The code is in Python.
Ask the user to enter the two integers, x and y
Since we want our program to run regardless of which entered value is larger, we need to compare the numbers to be able to create the loop that prints the numbers.
Check if x is greater than y. If it is, create a for loop that iterates from y+1 to x-1 and print the numbers
Otherwise, check if y is greater than x. If it is, create a for loop that iterates from x+1 to y-1 and print the numbers
If none of the previous part is executed, print that there are no integers between

Consider the following class definitions.public class Bike{private int numWheels = 2;// No constructor defined}public class EBike extends Bike{private int numBatteries;public EBike(int batteries){numBatteries = batteries;}}The following code segment appears in a method in a class other than Bike or EBike.EBike eB = new EBike(4);Which of the following best describes the effect of executing the code segment?А. An implicit call to the zero-parameter Bike constructor initializes the instance variable numwheels. The instance variable numBatteries is initialized using the value of the parameter batteries.
B. An implicit call to the one-parameter Bike constructor with the parameter passed to the EBike constructor initializes the instance variable numwheels. The instance variable numBatteries is initialized using the value of the parameter batteries. C. Because super is not explicitly called from the EBike constructor, the instance variable numWheels is not initialized. The instance variable numBatteries is initialized using the value of the parameter batteries.
D. The code segment will not execute because the Bike class is a superclass and must have a constructor. E The code segment will not execute because the constructor of the EBike class is missing a second parameter to use to initialize the numWheels instance variable.
Answer:
The answer is "Option A".
Explanation:
Please find the complete program in the attached file.
The given program includes a super-class Bike having a private integer numWheels parameter. The class EBike inherits the class Bike, EBike comprises one parameter function Object() which utilizes its variable number of the private integer Battery level of the battery parameter and the wrong choice can be defined as follows:
In choice B, it is wrong since there is no constructor with a single argument in the Bike class.
In choice C, it is wrong since there no need to call the base class constructor with the super keyword.
In choice, D is wrong because there no need to create a constructor of the base class.
In choice, E is wrong because it does not require the second EBike constructor parameter.
The statement that best describes the effect of executing the code segment is (a) an implicit call to the zero-parameter Bike constructor initializes the instance variable numwheels. The instance variable numBatteries is initialized using the value of the parameter batteries.
Given that the following object is defined in another class (say the Main class)
EBike eB = new EBike(4);
Also, the class Bike is a super class of the class EBike, where Ebike inherits the properties of class Bike.
It means that:
Option (a) is correct.
This is so, because:
An implicit call of one parameter to class cannot be used, as in option B.It is not necessary to call the Bike class, as in option C.It is not necessary to create a constructor of the EBike class, as in option D.Read more about classes at:

Write a program that reads in 10 numbers and displays the number of distinct numbers and the distinct numbers in their input order and separated by exactly one space (i.e., if a number appears multiple times, it is displayed only once). After the input, the array contains the distinct numbers. Here is a sample run of the program.
Answer:
Explanation:
The following code is written in Python. It creates a for loop that iterates 10 times, asking the user for a number every time. It then checks if the number is inside the numArray. If it is not, then it adds it to the array, if it is then it skips to the next iteration. Finally, it prints the number of distinct numbers and the list of numbers.
numArray = []
for x in range(10):
num = input("Enter a number")
if int(num) not in numArray:
numArray.append(int(num))
print("Number of Distince: " + str(len(numArray)))
for num in numArray:
print(str(num), end = " ")

Static variables are variables that still maintain their values outside the score which they are declared. They are declared with the static keyword
Example:
static int score = 30;
Local variables are variables whose scope are restricted to a block. Their values are restricted to the block which they are declared in.

score is a local variable to abcd() function
Security monitoring has detected the presence of a remote access tool classified as commodity malware on an employee workstation. Does this allow you to discount the possibility that an APT is involved in the attack
Answer:
No it doesn't
Explanation:
Targeted malware can be linked to such high resource threats as APT. Little or nothing can be done to stop such advanced persistent threats. It is necessary to carry out an evaluation on other indicators so that you can know the threat that is involved. And also to know if the malware is isolated or greater than that.
Part1) Given 3 integers, output their average and their product, using integer arithmetic.
Ex: If the input is:
10 20 5
the output is:
11 1000
Note: Integer division discards the fraction. Hence the average of 10 20 5 is output as 11, not 11.6667.
Note: The test cases include three very large input values whose product results in overflow. You do not need to do anything special, but just observe that the output does not represent the correct product (in fact, three positive numbers yield a negative output; wow).
Submit the above for grading. Your program will fail the last test cases (which is expected), until you complete part 2 below.
Part 2) Also output the average and product, using floating-point arithmetic.
Output each floating-point value with two digits after the decimal point, which can be achieved by executing
cout << fixed << setprecision(2); once before all other cout statements.
Ex: If the input is:
10 20 5
the output is:
11 1000
11.67 1000.00
Answer:
The program is as follows:
#include <iostream>
#include <iomanip>
using namespace std;
int main(){
int num1, num2, num3;
cin>>num1>>num2>>num3;
cout << fixed << setprecision(2);
cout<<(num1 + num2 + num3)/3<<" ";
cout<<num1 * num2 * num3<<" ";
return 0;
}
Explanation:
This declares three integer variables
int num1, num2, num3;
This gets input for the three integers
cin>>num1>>num2>>num3;
This is used to set the precision to 2
cout << fixed << setprecision(2);
This prints the average
cout<<(num1 + num2 + num3)/3<<" ";
This prints the product
cout<<num1 * num2 * num3<<" ";

second = Convert.ToInt32(secondString);
product = first * second;
Write("Thank you, {0}. The product of {1} and {2} is {3}", name,first, second, product);
}
}
Explanation:
string name;string firstString, secondString; ----- Replace secondSting with secondString,
int first, second, product;
Write("Enter your name >> "); --- Here, the quotes must be closed with corresponding quotes "
name = ReadLine(); The syntax of readLine is incorrect without the () brackets
Write("Hello, {0}! Enter an integer >> ", name);
firstString = ReadLine();
first = Convert.ToInt32(firstString); There is a dot between Convert and ToInt32
Write("Enter another integer >> ");
secondString = ReadLine(); --- Readline() should be written as ReadLine()
second = Convert.ToInt32(secondString);
product = first * second;
Write("Thank you, {0}. The product of {1} and {2} is {3}", name,first, second, product); --- The formats in {} should start from 0 because 0 has already been initialized for variable name

Exercise : Randomizer In this exercise, we are going to create a static class Randomizer that will allow users to get random integer values from the method nextInt() and nextInt(int min, int max). Remember that we can get random integers using the formula int randInteger = (int)(Math.random() * (range + 1) + startingNum). nextInt() should return a random value from 1 - 10, and nextInt(int min, int max) should return a random value from min to max. For instance, if min is 3 and max is 12, then the range of numbers should be from 3 - 12, including 3 and 12.
Answer:
Here the code is by using java.
Explanation:
//Randomizer.java
public class Randomizer {
public static int nextInt() {
//get random number from 1-10
int randInteger = (int) (Math.random() * (11) + 1);
//if number is greater than 10 or less than 1
while (randInteger > 10 || randInteger < 1) {
randInteger = (int) (Math.random() * (11) + 1);
}
return randInteger;
}
public static int nextInt(int min, int max) {
//formula to get random number from min-max
int randInteger = (int) (Math.random() * (max + 1) + min);
while (randInteger > max || randInteger < min) {
randInteger = (int) (Math.random() * (max + 1) + min);
}
return randInteger;
}
}
//RandomizerTester.java
public class RandomizerTester {
public static void main(String[] args) {
System.out.println("Results of Randommizer.nextInt()");
for (int i = 0; i < 10; i++) {
System.out.println(Randomizer.nextInt());
}
int min = 5;
int max = 10;
System.out.println("\n Results of Randomizer.nextInt(5,10)");
for (int i = 0; i < 10; i++) {
System.out.println(Randomizer.nextInt(min, max));
}
}
}

Best strategy to get through the module
First off, rushing through the activities and taking guess for each question (as suggested by (a)) will not help him;
He may complete the activities but sure, he won't learn from the module.
Also, reading through the units without completing the activities is not an appropriate method because Joe will not be able to test his knowledge at the end of the module.
The best strategy to employ is to read through the units and complete the activities, afterwards (option (b)).

The questions should be ones to which an impostor could not readily obtain the answers. How difficult would it be for you to provide the correct answer vs a malicious actor
Answer:
Explanation:
Security questions need to be very personal and very specific so that only one individual knows them. Some example questions would be the following...
What are the last 4 digits of your Social Security Number? ... every US citizen has a social security number and it is very personal document that only the owner should have access to.
What is the street name where you lived when you opened the account? ... on average a person moves 12 times in their lifetime, therefore, very few people would know the exact address where you lived when you opened the account.
What is your mother's maiden name? ... This is a common question asked by banks and financial institutions because most people will not know your mother and even less will know her maiden name. Therefore, it is a very good security question.
These are all questions that a bank will have the answers too and know if you are telling the truth or not, but are also questions that would be extremely difficult for anyone else to obtain. Mainly since some require a personal long time connection with you while others require very personal information which no one shares.

Which do not represent loop
Literally, looping means repeating an action or sequence of actions as long as a given condition is true.
For options (a) to (d), we have:
(a): if-then-else:
if statements are used to test conditions; depending on the truth or falsity of the condition, only one block of code can be executed at once.
In summary, if statements are not loops
(b): switch statements
This is an alternate to if statements and can be used in place of if statements.
Hence, switch statements are not loops
(c) and (d): for and while:
The above represent loops, because they both involve repetition of operations until the condition is no longer satisfied.

Write a program with a function that accepts a string as an argument and returns the number of uppercase, lowercase, vowel, consonants, and punctuation that the string contains. The application should let the user enter a string and should display the number of uppercases, lowercases, vowels, consonants, and punctuations that the string contains.
Answer:
Explanation:
The following code is written in Python. It is a function called checkString that takes in a string as an argument and loops through each char in that string and checking to see if it is lowercase, uppercase, vowel, consonant, or punctuations. It adds 1 to the correct variable. At the end of the loop it prints out all of the variables. The picture below shows a test output with the string "Brainly, Question."
def checkString(word):
uppercase = 0
lowercase = 0
vowel = 0
consonants = 0
punctuation = 0
vowelArray = ['a', 'e', 'i', 'o','u', 'y' ]
consonantArray = ['b', 'c', 'd', 'f', 'g', 'h', 'j', 'k', 'l', 'm', 'n', 'p', 'q', 'r', 's', 't', 'v', 'w', 'x', 'y', 'z']
punctuationArray = ['.', '!', '?', ',', ';', '(', ')']
for char in word:
if char.isupper():
uppercase += 1
else:
lowercase += 1
if char.lower() in vowelArray:
vowel += 1
elif char.lower() in consonantArray:
consonants += 1
if char in punctuationArray:
punctuation += 1
print('Uppercase: ' + str(uppercase))
print('Lowercase: ' + str(lowercase))
print('Vowels: ' + str(vowel))
print('Consonants: ' + str(consonants))
print('Punctuations: ' + str(punctuation))
The following Python program should print the sum of all the even numbers from 0 to 10 (0, 2, 4, 6, 8, 10), but it has two bugs:
x = 0
sum = 0
while x < 10:
sum = sum + x
x = x + 1
print(sum)
Write a sentence or two explaining what the errors are and how to fix them.
Answer:
To make the value 10 also part of the loop, the while statement must be "while x<=10" otherwise 10 is excluded. To have only even numbers, x should be increased by 2, not 1, i.e.: "x = x + 2".
Design and Analyze an algorithm for the following problem,
Give pseudocode for your algorithm.
Prove that your algorithm is correct.
Give the recurrence relation for the running time for your algorithm.
Solve the recurrence relation.
Suppose you are given 3n marbles that look identical, with one special marble that weighs more than the other marbles. You are also given a balancing scale that takes two items (or sets of items) and compares their weights. Design and analyze a divide and conquer algorithm to find the heavy marble using the balancing scale at most n times.
Answer:
If you have 3n marbles, then you need at least n weighings to find the heavier marble.
Algorithm:-
Label all marbles from 1 to n.
Divide the marbles into three groups G1, G2, and G3 such 2 groups G1, and G2 are compared to every other employing a pan, and therefore the third group G3 is kept aside.
Condition 1- If G1>G2, If the special marble is one among the primary two groups that are being weighed,i.e., special marble is in G1.
Condition 2- If G2>G1, If the special marble in group 2, G2.
Condition 3- If G1=G2 If the primary two groups weigh equal, then special marble is present within the third group, G3.
Take the group containing special marble and perform the above steps 1,2,3,4 on it.
Keep repeating the above steps until, a gaggle of three marbles is obtained, and therefore the special marble is found from that group by performing steps 1,2,3,4 on the group.
Explanation:
Pseudocode:-
function puzzle( G1, G2, G3)
{
Compare the values G1, G2
if G1>G2
return G1
else if G2>G1
return G2
else
return G3
end of function puzzle
}
function main()
{
print prompt "Enter the value of n"
Take the value of n from the user
while(n != 0)
{
Create 3 groups/arrays each of size 3n-1
G= puzzle( g1,g2,g3)
n= 3n-1
}
print the value in G
end of main
}
Recurrence relation for the running time for the algorithm:-
T (n) = 2T ( n1/3) + 1 with base T (3) = 1.,
here n is the total number of marbles.
We cannot apply the master theorem because of the cube root, so we draw the recursion tree.
First, we determine the height of the tree; denote this by h. By observing the powers of the arguments in the tree, we can see that in order to get to the base case of n = 3, it must be that,
n(1/2)h=3
(1/3)h=logn(3) = log 3/ log n = 1/log n
3h=log n
Now, since we do a constant amount of work (1, specifically) at each node in the recursion tree, we note that at depth d in the recursion tree we do 3d total work. We can therefore write the sum over the tree as a geometric series as follows:
[tex]T(n)= \sum_{d=0}^{log(logn)}3^d = (1-3^{log(log(n)+1)})/1-3)=(3^{log(log(n)+1)}-1)/2\\T (n) = 3 log (n)-1[/tex]
Therefore,
T (n) = Θ(log n).
