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.
Suppose that the following elements are added in the specified order to an empty binary search tree: Kirk, Spock, Scotty, McCoy, Chekov, Uhuru, Sulu, Khaaaan! Write the elements of the tree above in the order they would be seen by a pre-order, in-order, and post-order traversal. Type your solutions with the elements separated by spaces and/or commas, such as:
Answer:
Pre-order: Kirk, Chekov, Khaaaan, Spock, Scotty, McCoy, Sulu, Uhuru
In-order: Chekov, Khaaaan, Kirk, McCoy, Scotty, Spock, Sulu, Uhuru
Post-order: Khaaaan, Chekov, McCoy, Scotty, Sulu, Uhuru, Spock, Kirk
Explanation:
The binary search tree is described in the diagram below.
The pre-order traversal of the binary tree gets the root, then the left node and right node. The in-order traversal picks the left node, the root node, and then the right node while the post-order traversal of the binary tree follows the left node, right node, and then the root node.
Which is true regarding how methods work? Group of answer choices If a method returns a variable, the method stores the variable's value until the method is called again A return address indicates the value returned by the method After a method returns, its local variables keep their values, which serve as their initial values the next time the method is called A method's local variables are discarded upon a method's return; each new call creates new local variables in memory
Answer:
A method's local variables are discarded upon a method's return; each new call creates new local variables in memory.
Explanation:
A local variable can be defined as an argument passed to a function or a variable that is declared within a function and as such can only be used or accessed within the function.
This ultimately implies that, a local variable is effective whilst the function or block is being executed (active).
Basically, all local variables can only be a member of either the register storage, static or auto (dynamic) categories in computer programming.
The true statement regarding how methods work is that a method's local variables are discarded upon a method's return; each new call creates new local variables in memory. This is so because these local variables are only allocated a storage that is within the frame of the method which is being executed on the run-time stack and would be discarded upon a method's completion or return.
Statement that is true regarding how methods work is :A method's local variables are discarded upon a method's return; each new call creates new local variables in memory.
A local variable serves as a variable which can be accessible within a particular part of a program.
These variables are usually defined within that routine and it is regarded as been local to a subroutine.
We can conclude that in method's local variables it is possible for each new call creates new local variables in memory.

1.21 LAB: Divide by x
Write a program using integers user_num and x as input, and output user_num divided by x three times.
Answer:
Explanation:
The following code is written in Python. It is a function called divide_by_x and takes the user inputs as described. It then raises x to the third power and divides user_num by that number. This gives the same result as user_num divided by x three times. The answer is saved in the variable answer which is then returned to the user.
def divide_by_x(user_num, x):
answer = user_num / (x**3)
return answer
The program is an illustration of the division arithmetic operation.
The program in Python, where comments are used to explain each line is as follows:
#This gets input for user_num
user_num = int(input())
#This gets input for x
x = int(input())
This loop is repeated three times
for i in range(1,4):
#This divides user_num by x, each time
user_num /= x
#This prints the required output
print(user_num)
At the end of the program, user_num is divided three times by x and then printed.

Answer:
An array.
Explanation:
An array can be defined as a structure that organizes data in a list that is commonly 1-dimensional or 2-dimensional.
Simply stated, an array refers to a set of memory locations (data structure) that comprises of a group of elements with each memory location sharing the same name. Therefore, the elements contained in array are all of the same data type e.g strings or integers.
Basically, in computer programming, arrays are typically used by software developers to organize data, in order to search or sort them.
Binary search is an efficient algorithm used to find an item from a sorted list of items by using the run-time complexity of Ο(log n), where n is total number of elements. Binary search applies the principles of divide and conquer.
In order to do a binary search on an array, the array must first be sorted in an ascending order.
Hence, array elements are mainly stored in contiguous memory locations on computer.

Write a program that prompts the user to enter a fraction in the following format (x/y). You may assume that the user will input numbers and a slash, but your program should deal with spaces. Use String methods to parse out the numerator and denominator (e.g. indexOf(), trim(), substring() etc.) Once you have the numerator and denominator, your program will determine whether the number is a proper fraction or an improper fraction. If it is a proper fraction, display the number. If not, reduce it to a mixed fraction or to an integer (see sample output below).
Answer:
fraction = input("enter fraction x/y: ")
if len(fraction) == 3:
if fraction[1] == "/":
try:
num = int(fraction[0])
den = int(fraction[2])
if num < den:
print(f"{num}/{den} is a proper fraction")
else:
if num% den == 0
print(f"{num}/{den} is an improper fraction and can be reduced to {num/den}")
else:
print(f"{num}/{den} is an improper fraction and can be reduced to {num//den} + {num - (den * (num//den))}/{den}")
except ValueError:
print("numerator and denominator must be integer numbers")
Explanation:
The try and except statement of the python program is used to catch value error of the input fraction of values that are not number digits. The program converts the numerator and denominator string values to integers and checks for the larger value of both.
The program prints the fraction as a proper fraction if the numerator is lesser and improper if not.
Define a class called UpdatedBook which inherits the BookInfo class created in Programming Project 3. This new class should contain an integer field for the edition number of the book, a constructor to create the UpdatedBook object accepting as input the author, title, and edition number of the book, and a getter method to return the edition number.
Answer:
Following are the class definition code to this question:
class UpdatedBook : BookInfo//defining a class UpdatedBook that inherits the BookInfo class
{
public:
int edition_Number;//defining an integer variable
UpdatedBook (string title,string author,int edition):BookInfo(b_title,b_author)//defining a constructor that
{
edition_Number=edition;
}
int getEdition_Number()
{
return edition_Number;
}
};
Explanation:
In this question, the "BookInfo" class is not defined, that's why we define this code as above.
In this code, a class "UpdatedBook" is defined that inherits its base class "BookInfo" inside the "UpdatedBook" class an integer variable "edition_Number" is declared, which is used to holding the integer value.
In the next step, a parameterized constructor is declared, that accepts a three-parameter and also inherits its base class parameterized constructor, and at the last, a get method is used that returns the edition number value.
Consider the following incomplete method, which is intended to return the longest string in the string array words. Assume that the array contains at least one element.
public static String longestWord(String[] words)
{
/* missing declaration and initialization */
for (int k = 1; k < words.length; k++)
{
if (words[k].length() > longest.length())
{
longest = words[k];
}
}
return longest;
}
Which of the following can replace /* missing declaration and initialization */ so that the method will work as intended?
a. int longest = 0;
b. int longest = words[0].length();
c. String longest = "";
d. String longest = words[0];
e. String longest = words[1];
Answer:
String longest = "";
Explanation:
The initialization that would allow the method to work as intended would be the following
String longest = "";
This is because the method is looping through the array provided as an argument and comparing each word in the array with the word saved inside the variable called longest. The length of both are compared and if the word in the array is longer than the string saved in the variable longest then it is overwritten with the word in the array.

It makes it much easier to address whether another 'Quick Sort' or even the 'Merge Sort' issue by converting the very same problem throughout the number problem.
All the cases use for the Merge Sort, in which it utilizes its evenly divide or overcome strategy where the category is reciprocally divided into two parts where the number becomes measured at n==2, and the outcome extends.
Assume we get 7 squads:
2 4 5 4 3 1 6
Recursively split the above teams:
2 4 5 4 3 1 6
2 4 5 4 3 1 6
We'll equate such figures with base-case (n==2) (have a match against each other)
2 4 4 5 1 3 6 (number of matches 1(2,4) + 1(5,4) + 1(3,1) = 3)
Now the division is combined.

The Fast as Light Shipping company charges the following rates. Weight of the item being sent Rate per 100 Miles shipped 2kg or less. $0.25 Over than 2 kg but not more than 10 kg $0.30 Over 10 kg but not more than 20 kg. $0.45 Over 20 kg, but less than 50kg. $1.75 Write a program that asks for the weight of the package, and the distance to be sent. And then displays the charge.
Answer:
weight = float(input("Enter the weight of the package: "))
distance = float(input("Enter the distance to be sent: "))
weight_charge = 0
if weight <= 2:
weight_charge = 0.25
elif 2 < weight <= 10:
weight_charge = 0.3
elif 10 < weight <= 20:
weight_charge = 0.45
elif 20 < weight <= 50:
weight_charge = 1.75
if int(distance / 100) == distance / 100:
d = int(distance / 100)
else:
d = int(distance / 100) + 1
total_charge = d * weight_charge
print("The charge is $", total_charge)
Explanation:
*The code is in Python.
Ask the user to enter the weight and distance
Check the weight to calculate the weight_cost for 100 miles. If it is smaller than or equal to 2, set the weight_charge as 0.25. If it is greater than 2 and smaller than or equal to 10, set the weight_charge as 0.3. If it is greater than 10 and smaller than or equal to 20, set the weight_charge as 0.45. If it is greater than 20 and smaller than or equal to 50, set the weight_charge as 1.75
Since those charges are per 100 miles, you need to consider the distance to find the total_charge. If the int(distance / 100) is equal to (distance / 100), you set the d as int(distance / 100). Otherwise, you set the d as int(distance / 100) + 1. For example, if the distance is 400 miles, you need to multiply the weight_charge by 4, int(400/100) = 4. However, if the distance is 410, you get the int(400/100) = 4, and then add 1 to the d for the extra 10 miles.
Calculate the total_charge, multiply d by weight_charge
Print the total_charge
Write a program that has a user guess a secret number between 1 and 10. Store the secret number in a variable called secret Number and allow the user to continually input numbers until they correctly guess what secretNumber is. For example, if secretNumber was 6, an example run of the program may look like this:
Answer:
The program in Python is as follows:
import random
secretNum = random.randint(1,10)
userNum = int(input("Take a guess: "))
while(userNum != secretNum):
print("Incorrect Guess")
userNum = int(input("Take a guess: "))
print("You guessed right")
Explanation:
This imports the random module
import random
This generates a secrete number
secretNum = random.randint(1,10)
This prompts the user to take a guess
userNum = int(input("Take a guess: "))
This loop is repeated until the user guess right
while(userNum != secretNum):
print("Incorrect Guess")
userNum = int(input("Take a guess: "))
This is executed when the user guesses right
print("You guessed right")

Answer:
In Python:
#1
service = input("Enter desired auto service: ")
print("You entered: "+service)
#2
if service.lower() == "oil change":
print("Cost of oil change: $35")
elif service.lower() == "car wash":
print("Cost of car wash: $7")
elif service.lower() == "tire rotation":
print("Cost of tire rotation: $19")
else:
print("Invalid Service")
Explanation:
First, we prompt the user for the auto service
service = input("Enter desired auto service: ")
Next, we print the service entered
print("You entered: "+service)
Next, we check if the service entered is available (irrespective of the sentence case used for input). If yes, the cost of the service is printed.
This is achieved using the following if conditions
For Oil Change
if service.lower() == "oil change":
print("Cost of oil change: $35")
For Car wash
elif service.lower() == "car wash":
print("Cost of car wash: $7")
For Tire rotation
elif service.lower() == "tire rotation":
print("Cost of tire rotation: $19")
Any service different from the above three, is invalid
else:
print("Invalid Service")
What is the output of the following code snippet? int s1 = 20; if (s1 <= 20) { System.out.print("1"); } if (s1 <= 40) { System.out.print("2"); } if (s1 <= 20) { System.out.print("3"); }
Answer:
The program outputs 123
Explanation:
The first line of the program initializes s1 to 20
The second line checks if s1 is less than or equal to 20.
This is true,
So, 1 is printed
The third line checks if s1 is less than or equal to 40.
This is true,
So, 2 is printed
The fourth line checks if s1 is less than or equal to 20.
This is true,
So, 3 is printed
Hence, the output is 123

for k in alpha:#defining for loop that stores values in the dictionary
d[k]= set()# use dictionary to set value in list
for i in s:# defining for loop to convert value in lower case
i = i.lower() #convert value into lower case by using lower method
a = i[0]# adding value into dictionary
d[a].add(i) # use add method to hold value in dictionary
for k,v in sorted(d.items()):#use for loop to convert value in assending order
if len(d[k])!=0: #use if block to check length of dictionary
print(k,":", sorted(v))#use print to sort value
f_name = 'input.txt'#defining a variable that open file
with open(f_name) as fi:#use open method to read file
data = fi.read() # read file data
dic_sorted(data)#calling method
output:
please find the attached file.
Explanation:
In the code, the "dic_sorted" method is used, which accepts a data variable as a parameter, and inside the method, a split method and an empty dictionary are defined, that converts and holds the value by alphabetical order, for this it defines three for loops.
In the first for loop, it holds a value in the dictionary, and in the second loop it converts a value into the lower case, and in the third loop, it stores the value in its alphabetical order.

Write a program to take in a time-of-day on the command-line as 3 integers representing hours, minutes, and seconds, along with a 4th argument of additional seconds. Recompute the time by adding the additional seconds to the time in the first three command-line arguments. Output: - display the original time given on the command-line - display the newly computed time Example: python computeTime.py 5 59 32 30 Initial time: 5:59:32 Computed time: 6:00:02 {6:0:2 would also be acceptable}
Answer:
In Python:
hh = int(input("Hour: ")) * 3600
mm = int(input("Minutes: ")) * 60
ss = int(input("Seconds: "))
seconds = int(input("Additional Seconds: "))
time = hh+ mm + ss + seconds
hh = int(time/3600)
time = time - hh * 3600
mm = int(time/60)
ss = time - mm * 60
while(hh>24):
hh = hh - 24
print(str(hh)+" : "+str(mm)+" : "+str(ss))
Explanation:
We start by getting the time of the day. This is done using the next three lines
hh = int(input("Hour: ")) * 3600
mm = int(input("Minutes: ")) * 60
ss = int(input("Seconds: "))
Then, we get the additional seconds
seconds = int(input("Additional Seconds: "))
The new time is then calculated (in seconds)
time = hh+ mm + ss + seconds
This line extracts the hours from the calculated time (in seconds)
hh = int(time/3600)
time = time - hh * 3600
This line extracts the minutes from the calculated time (in seconds)
mm = int(time/60)
This line gets the remaining seconds
ss = time - mm * 60
The following iteration ensures that the hour is less than 24
while(hh>24):
hh = hh - 24
This prints the calculated time
print(str(hh)+" : "+str(mm)+" : "+str(ss))
