Output values below an amount
Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value.
Ex: If the input is:
5 50 60 140 200 75 100
the output is:
50 60 75
The 5 indicates that there are five integers in the list, namely 50, 60, 140, 200, and 75. The 100 indicates that the program should output all integers less than or equal to 100, so the program outputs 50, 60, and 75.
For coding simplicity, follow every output value by a space, including the last one. Such functionality is common on sites like Amazon, where a user can filter results.

Answers

Answer:

Explanation:

The following code is written in Python and it is a function called filter, which takes in the requested inputs. It then places the threshold in its own variable and pops it out of the array of inputs. Then it loops through the array comparing each element with the threshold and printing out all of the ones that are less than or equal to the threshold.

def filter():

   num_of_elements = input("Enter a number: ")

   count = 0

   arr_of_nums = []

   while count <= int(num_of_elements):

       arr_of_nums.append(input("Enter a number: "))

       count += 1

   threshold = arr_of_nums[-1]

   arr_of_nums.pop(-1)

   print(threshold)

   for element in arr_of_nums:

       if int(element) < int(threshold):

           print(element)

       else:

Suppose Alice and Bob are sending packets to each other over a computer network. SupposeTrudy positions herself in the network so that she can capture all the packets sent by Alice and sendwhatever she wants to Bob; she can also capture all the packets sent by Bob and send whatever she wantsto Alice. List one active and one passive malicious thing that Trudy can do from this position.

Answers

Explanation:

can observe the contents of all the packets sent and even modify the content.can prevent packets sent by both parties from reaching each other.

From a network security standpoint, since we are told that Trudy "positions herself in the network so that she can capture all the packets sent", it, therefore implies that the communication between Alice and Bob is vulnerable to modification and deletion.

Imagine that you are designing an application where you need to perform the operations Insert, DeleteMaximum, and Delete Minimum. For this application, the cost of inserting is not important, because itcan be done off-line prior to startup of the time-critical section, but the performance of the two deletionoperations are critical. Repeated deletions of either kind must work as fast as possible. Suggest a datastructure that can support this application, and justify your suggestion. What is the time complexity foreach of the three key operation

Answers

Answer:

A stack data structure should be used. The time complexity of the insert, delete minimum and maximum operation is O(1).

Explanation:

The stack data structure is an indexed structure that holds data in an easily retrievable way. Data is held in a first-in last-out method as elements in the structure are popped out from the end of the stack when retrieved sequentially.

The worst-case time complexity of getting the minimum and maximum elements in a stack and deleting it is O(1), this is also true for inserting elements in the stack data structure.

Consider the following class definition.
public class Tester
{
privtae int num1;
private int num2;
/missing constructor /
}
The following statement appears in a method in a class other than Tester. It is intended t o create a new Tester object t with its attributes set to 10 and 20.
Tester t = new Tester(10,20);

Which can be used to replace / missing constructor / so that the object t is correctly created?

Answers

Answer:

Explanation:

The following constructor needs to be added to the code so that the object called t can be created correctly...

public Tester(int arg1, int arg2) {

    num1 = arg1;

    num2 = arg2;

}

This basic constructor will allow the object to be created correctly and will take the two arguments passed to the object and apply them to the private int variables in the class. The question does not state what exactly the Tester constructor is supposed to accomplish so this is the basic format of what it needs to do for the object to be created correctly.

g n this program, you will prompt the user for three numbers. You need to check and make sure that all numbers are equal to or greater than 0 (can use an if or if/else statement for this). You will then multiply the last two digits together, and add the result to the first number. The program should then start over, once again asking for another three numbers. This program should loop indefinitely in this way. If the user enters a number lower than 0, remind the user that they need to enter a number greater than or equal to 0 and loop the program again.

Answers

Answer:

In Python:

loop = True

while(loop):

   nm1 = float(input("Number 1: "))

   nm2 = float(input("Number 2: "))

   nm3 = float(input("Number 3: "))

   if (nm1 >= 0 and nm2 >= 0 and nm3 >= 0):

       result = nm2 * nm3 + nm1

       print("Result: "+str(result))

       loop = True

   else:

       print("All inputs must be greater than or equal to 0")

       loop = True

Explanation:

First, we set the loop to True (a boolean variable)

loop = True

This while loop iterates, indefinitely

while(loop):

The next three lines prompt user for three numbers

   nm1 = float(input("Number 1: "))

   nm2 = float(input("Number 2: "))

   nm3 = float(input("Number 3: "))

The following if condition checks if all of the numbers are greater than or equal to 0

   if (nm1 >= 0 and nm2 >= 0 and nm3 >= 0):

If yes, the result is calculated

       result = nm2 * nm3 + nm1

... and printed

       print("Result: "+str(result))

The loop is then set to true

       loop = True

   else:

If otherwise, the user is prompted to enter valid inputs

       print("All inputs must be greater than or equal to 0")

The loop is then set to true

       loop = True

If you are writing an algorithm and you aren’t confident that you understand the problem, what can you do?

Answers

Answer:

divide it into smaller pieces

Explanation:

Usually, the main reason a programmer does not understand a problem fully is that there is too much information. The best way to try and fully understand a problem is to divide it into smaller pieces. Start off by answering the question what is the expected output for an input. Then divide each individual issue within the problem. This will allow you as a programmer/developer to create an individual solution for each individual issue within the problem and then test to make sure that the input gives the correct output.

company gives the following discount if you purchase a large amount of supply. Units Bought Discount 10 - 19 20% 20 - 49 30% 50 - 99 35% 100 40% If each item is $4.10. Create a program that asks the user how many items they want to buy, then calculates the pre-discount price, the amount of discount and the after discount price. So for example if order 101 items, I should see something similar to the following: With your order of 101 items, the total value will be $414.10 with a discount of $165.64 for a final price of $248.46. Your output should be very well organized, and use the correct formatting. (Including precision)

Answers

Answer:

In Python:

order = int(input("Order: "))

discount = 0

if(order >= 10 and order <20):

    discount = 0.20

elif(order >= 20 and order <50):

    discount = 0.30

elif(order >= 50 and order <100):

    discount = 0.35

elif(order >= 100):

    discount = 0.40

price = order * 4.1

discount = discount * price

print("With your order of "+str(order)+" items, the total value will be $"+str(round(price,2))+" with a discount of $"+str(round(discount,2))+" for a final price of $"+str(round((price-discount),2)))

Explanation:

This prompts the user for number of orders

order = int(input("Order: "))

This initializes the discount to 0

discount = 0

For orders between 10 and 19 (inclusive)

if(order >= 10 and order <20):

-----------discount is 20%

    discount = 0.20

For orders between 20 and 49 (inclusive)

elif(order >= 20 and order <50):

-----------discount is 30%

    discount = 0.30

For orders between 50 and 99 (inclusive)

elif(order >= 50 and order <100):

-----------discount is 35%

    discount = 0.35

For orders greater than 99

elif(order >= 100):

-----------discount is 40%

    discount = 0.40

This calculates the total price

price = order * 4.1

This calculates the pre discount

discount = discount * price

This prints the report

print("With your order of "+str(order)+" items, the total value will be $"+str(round(price,2))+" with a discount of $"+str(round(discount,2))+" for a final price of $"+str(round((price-discount),2)))

Explanation:

When dealing with Java syntax you always need to initialize an ArrayList object with its constructor. From the options listed the only correct option would be B: new ArrayList(). This would correctly initialize the ArrayList object but is not necessarily the recommended way of doing this. The truly recommended way would be the following

ArrayList<Thing> a = new ArrayList<Thing>()

ArrayLists are simply resizable array.

The statement that can replace the missing code is (b) new ArrayList();The statements that can replace the missing code is (c) I and III only

The syntax to create an ArrayList is:

ArrayList<Type> str = new ArrayList<Type>();

Another possible syntax is:

ArrayList var_name= new ArrayList();

The above declarations mean that: the statement that can replace the missing code is (b) new ArrayList();

In Cloud9, create a new file called function.cpp. If you aren't sure how to create a new .cpp file in the Cloud9 environment, refer Slide 24 of the Cloud9SetUpSlides (Links to an external site.). In this new file write a function called swapInts that swaps (interchanges) the values of two integers that it is given access to via pointer parameters. Write a main function that asks the user for two integer values, stores them in variables num1 and num2, calls the swap function to swap the values of num1

Answers

Answer:

#include <iostream>  

using namespace std;  

void swapInts(int* x, int* y) {

*x = *x + *y;

*y= *x - *y;

*x = *x - *y;

int main(){    

int num1, num2;

cout << "Before swap:";

cin>>num1;  cin>>num2;

swapInts(&num1, &num2);  

cout<<"After swap:"<<num1<<" "<<num2;

}      

Explanation:

The function begins here:

This line defines the function

void swapInts(int* x, int* y) {

The next three line swap the integer values

*x = *x + *y;

*y= *x - *y;

*x = *x - *y;  

}

The main begins here:

int main(){  

This line declares two integer variables

int num1, num2;

This line prompts the user for inputs before swap

cout << "Before swap:";

This line gets user inputs for both integers

cin>>num1;  cin>>num2;

This line calls the function

swapInts(&num1, &num2);  

This prints the numbers after swap

cout<<"After swap:"<<num1<<" "<<num2;

A year with 366 days is called a leap year. Leap years are necessary to keep the calendar in sync with the sun, because the earth revolves around the sun once very 365.25 days. As a result, years that are divisible by 4, like 1996, are leap years. However, years that are divisible by 100, like 1900, are not leap years. But years that are divisible by 400, like 2000, are leap years. Write a program named leap_year.py that asks the user for a year and computes whether that year is a leap year.

Answers

Answer:

Follows are the code to this question:

y = int(input("Enter a year: "))#input year value  

if((y%4==0) and (y%100==0) or y%400==0):#defining if block for check leap year condition

   print("Given year {0}, is a leap year".format(y))#print value  

else:#else block

   print("Given year {0}, is not a leap year".format(y))#print value  

Output:

Enter a year: 1989

Given year 1989, is not a leap year

Explanation:

In the python code, the y variable uses the input method for input the value from the user-end. In the next step, if a conditional block is used, that's checks the leap-year condition. if the condition is true it will print leap year value with the message, otherwise, it will go to else block that prints not a leap year message.

Answers

Answer:

8.22 × 10²⁰ years

Explanation:

Given that:

Total frequency = 100 million per record

The length of the key used for the encryption = 112 bit key

To calculate the number of seconds in  a year, we have:

= 365 × 24 × 60 × 60

= 3.1536 × 10⁷ seconds

Thus, on average, the number of possible keys that is required to check for the decryption should be at least  2¹¹¹ keys.

[tex]\mathbf{ = \dfrac{2^{111} \times 10^6}{3.1536 \times 10^7} = 8.22 \times 10^{20} \ years}[/tex]

Thus, it will take a total time of about 8.22 × 10²⁰ years on average.
