Answer:
In Python:
import random
lotterylist = []
for number in range(7):
lotterylist.append(random.randint(0,9))
for number in lotterylist:
print(number, end = ', ')
Explanation:
This line imports the random library
import random
This line creates an empty list
lotterylist = []
The instructions in this loop will be performed 7 times
for number in range(7):
This line generates a random number between 0 and 9 (inclusive) and then appends the number into lotterylist
lotterylist.append(random.randint(0,9))
This iterates through lotterylist
for number in lotterylist:
This prints the content of the list on a line (seperated by comma)
print(number, end = ', ')
Assume that you are able to do an exhaustive search for the key to an encrypted message at the rate of 100 Million trials per second. (a) (7 Points) How long in (days or years) would it take for you to find the key on the average to a code that used 112-bit key on average
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.

Consider the following statement, which is intended to create an ArrayList named numbers that can be used to store Integer values.
ArrayList numbers = /* missing code */;
Which of the following can be used to replace /* missing code */ so that the statement works as intended?
new ArrayList()
new ArrayList
new ArrayList()
A: III only
B: I and II only
C: I and III only
D:II and III only
E: I, II, and III
Answer:
B: new ArrayList()
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 onlyThe 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();
While the statements that can replace the missing code is (c) I and III only

PHP is based on C rather than ______.
Select one:
a. PEARL
b. JAVA
c. PERL
d. COBOL
Answer:
The answer is "option b and option d"
Explanation:
In this question, both choice "b and c" is correct because Java is compiled and run on a JVM and it uses the byte code. On the other hand, PHP has interpreted language, that compiled into the bytecode after that the output engine interpreted. Similarly, the COBOL is used for enterprise, finance, and administrative systems, and PHP is used in web creation.
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.
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
We have looked at several basic design tools, such as hierarchy charts, flowcharts, and pseudocode. Each of these tools provide a different view of the design as they work together to define the program. Explain the unique role that each design tool provides (concepts and/or information) to the design of the program.
Answer:
Answered below
Explanation:
Pseudocode is a language that program designers use to write the logic of the program or algorithms, which can later be implemented using any programming language of choice. It helps programmers focus on the logic of the program and not syntax.
Flowcharts are used to represent the flow of an algorithm, diagrammatically. It shows the sequence and steps an algorithm takes.
Hierarchy charts give a bird-eye view of the components of a program, from its modules, to classes to methods etc.

Write a program named BinaryToDecimal.java that reads a 4-bit binary number from the keyboard as a string and then converts it into decimal. For example, if the input is 1100, the output should be 12. (Hint: break the string into substrings and then convert each substring to a value for a single bit. If the bits are b0, b1, b2, b3, then decimal equivalent is 8b0 4b1 2b2 b3)
Answer:
import java.util.*;
public class BinaryToDecimal
{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String binaryNumber;
int decimalNumber = 0;
System.out.print("Enter the binary number: ");
binaryNumber = input.nextLine();
for(int i=0; i<binaryNumber.length(); i++){
char c = binaryNumber.charAt(binaryNumber.length()-1-i);
int digit = Character.getNumericValue(c);
decimalNumber += (digit * Math.pow(2, i));
}
System.out.println(decimalNumber);
}
}
Explanation:
Create a Scanner object to be able to get input from the user
Declare the variables
Ask the user to enter the binaryNumber as a String
Create a for loop that iterates through the binaryNumber. Get each character using charAt() method. Convert that character to an integer value using Character.getNumericValue(). Add the multiplication of integer value and 2 to the power of i to the decimalNumber variable (cumulative sum)
When the loop is done, print the decimalNumber variable
If you are writing an algorithm and you aren’t confident that you understand the problem, what can you do?
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.
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?
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.

Complete question :
Sue is planning a theme park trip for her husband, herself, and her three children. She has a budget of $500. Adult tickets cost $55 each, and child tickets cost $25 each. Which formula should go in cell B4?
Answer:
=E1B1+E2B2
Explanation:
Cost of adult ticket = $55
Child ticket = $25
Number of adult = 2
Number of children = 3
Assume :
Cost of adult ticket = $55 = E1
Child ticket = $25 = E2
Number of adult = 2 = B1
Number of children = 3 = B2
The formula that should go into cell B5 in other to calculate total amount :

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.
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.
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)
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)))

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.
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:
continue
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
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.

What is computer programming?Computer programming is defined as the process of carrying out a specific computation, typically through creating an executable computer program. Computer programmers create code and scripts, modify them, and test them to make sure that software and applications function as intended. They convert the blueprints made by engineers and software developers into computer-readable instructions.
The algorithm determines whether the key the number you're looking for and the array's middle value are equal. If so, the key is in the middle and the search is complete. The program then determines if the key is larger or less than the middle value if it isn't.
Thus, PRE: True POST: is Sorted(a) An > 1 C) PRE : n > 1A is Sorted (a). 10 sxs a[n-1] POST: result == x E a vissorted (a).
