Suppose you have a stack ADT (i.e., an Abstract Data Type that includes operations to maintain a stack. Design a flowchart or suitable logical diagram to show you could implement a queue’s enqueue and dequeue operations using two stacks, stack 1 and stack 2.

Answers

Answer 1

Answer:

One approach would be to move all items from stack1 to stack2 (effectively reversing the items), then pop the top item from stack2 and then put them back.

Assume you use stack1 for enqueueing. So enqueue(x) = stack1.push(x).

Dequeueing would be:

- For all items in stack1: pop them from stack1 and push them in stack 2.

- Pop one item from stack2, which will be your dequeue result

- For all items in stack2: pop them from stack2 and push them in stack 1.

Hope it makes sense. I'm sure you can draw a diagram.

Cryptarithmetic algorithm

Answers

Answer:

CryptArithmetic or verbal arithmetic is a class of mathematical puzzles in which the digits are replaced by letters of the alphabet or other symbols. Usually it is required that each letter would be replaced by a unique digit. Each letter having different value from the other letters.

Explanation:

Cryptarithm now denotes mathematical problems usually calling for addition, subtraction, multiplication, or division and replacement of the digits by letters of the alphabet or some other symbols. ... Since D × B has only one digit, B must be 3 or less. The only two possibilities are 0 and 2.

Based on the naming recommendations in the book, which of the following is a good identifier for a variable that will be used to hold an employee’s phone number? a. EmployeePhoneNumber b. emphonumber c. employee_phone_number d. empPhoneNum

Answers

Answer:

A good identifier for a variable that will be used to hold an employee’s phone number is:

a. EmployeePhoneNumber

Explanation:

An identifier is a string that uniquely identifies or names the entity or an object.  The object or entity may be a constant, variable, structure, function, etc. Identifiers can be formed from uppercase and lowercase letters, digits, and underscores.  Meaningful identifiers mostly favor the use of long descriptive names like EmployeePhoneNumber.  However, the other options can still be used.

Chassis intrusion detection is an option that can be enabled/disabled in the BIOS setup utility (if a BIOS comes equipped with this feature).Coupled with a hardware sensor mounted insided the computer case, this functionality can be used to check if the case was opened and display a notification alert during next boot.
a. True
b. False

Answers

Answer: True

Explanation:

Chassis intrusion detection is simply a vital security feature which is used typically by large corporate networks. It's simply an intrusion detection method which can be used in alerting a system administrator when there's a situation whereby a person opens a computer case which can then be investigated in order to know if the computer hardware has been tampered with.

It should also be noted that the chassis intrusion detection can then be either enabled or disabled in the BIOS setup utility if a BIOS comes equipped with this feature.

A hammer tool can only be used by one technician at a time to perform hitting. Accordingly, you have developed a Hammer class with a hit method. Objects of class Hammer are used to simulate different hammers, while threads are created to simulate users. Which situation needs to add the synchronized keyword to the hit method

Answers

Answer:

Explanation:

The synchronized keyword needs to be active on the hit method at any point where 2 or more threads (users) exists at any given moment. This is in order to prevent two or more users from trying to perform a hammer hit at the same time. This is what the synchronized keyword is used for. It prevents the more than one thread from calling the specific method at the same time. Instead it adds the action to a sequence so that the second thread calls the hit method only after the first thread's hit method finishes.

Write a program that inputs a line of text tokenizing the line with function strtok and outputs the tokens in reverse order i.e. last token in the sentence is printed first and first token is printed last. The user must be able to specify at most 80 characters in the sentence.

}

/* we first ask for user input using the prompt function. We save this in a variable gettext which we pass to the strtok function. This function first splits the text and makes it an array so we are able to count how many characters the user enters and set an if..else condition to handle characters that may be more than 80. The reverse and join functions are then used respectively to reverse and return the string.*/

Assume a TCP sender is continuously sending 1,090-byte segments. If a TCP receiver advertises a window size of 5,718 bytes, and with a link transmission rate 26 Mbps an end-to-end propagation delay of 22.1 ms, what is the utilization

Answers

Answer:

for the 5 segments, the utilization is 3.8%

Explanation:

Given the data in the question;

segment size = 1090 bytes

Receiver window size = 5,718 bytes

Link transmission rate or Bandwidth = 26 Mbps = 26 × 10⁶ bps

propagation delay = 22.1 ms

so,

Round trip time = 2 × propagation delay = 2 × 22.1 ms = 44.2 ms

we determine the total segments;

Total segments = Receiver window size / sender segment or segment size

we substitute

Total segments = 5718 bytes / 1090 bytes

Total segments = 5.24587 ≈ 5

Next is the throughput

Throughput = Segment / Round trip

Throughput = 1090 bytes / 44.2 ms

1byte = 8 bits and 1ms = 10⁻³ s

Throughput = ( 1090 × 8 )bits / ( 44.2 × 10⁻³ )s

Throughput = 8720 bits / ( 44.2 × 10⁻³ s )

Throughput = 197.285 × 10³ bps

Now Utilization will be;

Utilization = Throughput / Bandwidth

we substitute

Utilization = ( 197.285 × 10³ bps ) / ( 26 × 10⁶ bps )

Utilization = 0.0076

Utilization is percentage will be ( 0.0076 × 100)% = 0.76%

∴ Over all utilization for the 5 segments will be;

⇒ 5 × 0.76% = 3.8%

Therefore, for the 5 segments, the utilization is 3.8%

Add a function to problem to display the last name and highest, last name and lowest and average exam score. Hint: for highest initialize a variable to 0 (high_var). If the array value is higher than the high_var then set high_var to the array value and set high_index to the position of the array. Proceed through the array until you get to the end. Do the same for finding the lowest using low_var set to 999 (higher than the highest value). For the average score, sum all the exam scores as you proceed through the loop. Use a for loop to go through each occurrence of the arrays. Note you can do all this with one for loop but if it makes more sense to you to use multiple for loops that is ok too.

Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (current_price * 0.051) / 12. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print('{:.2f}'.format(your_value))

Answers

Answer:

The program in Python is as follows:

current_price = int(input("Current Price: "))

last_price = int(input("Last Month Price: "))

change = current_price - last_price

mortgage = (current_price * 0.051) / 12

print('Change: {:.2f} '.format(change))

print('Mortgage: {:.2f}'.format(mortgage))

Explanation:

This gets input for current price

current_price = int(input("Current Price: "))

This gets input for last month price

last_price = int(input("Last Month Price: "))

This calculates the price change

change = current_price - last_price

This calculates the mortgage

mortgage = (current_price * 0.051) / 12

This prints the calculated change

print('Change: {:.2f} '.format(change))

This prints the calculated monthly mortgage

print('Mortgage: {:.2f}'.format(mortgage))

Answer:

current_price = int(input())

last_months_price = int(input())

change = current_price - last_months_price

mortgage = current_price * 0.051 / 12

print('This house is $', end= '')

print(current_price, end= '. ')

print('The change is $', end= '')

print(change, end= ' ')

print('since last month.')

print('The estimated monthly mortgage is $', end= '')

print(mortgage, end='0.\n')
