A) DVD-RW
B) DVD-R
C) solid state hard drive

Answers

Answer 1

Answer:

DVD-R is a good choice for long-term archiving because the stored data do not degrade over time. This is due to its write-once, read-many nature, which makes it less likely to degrade compared to magnetic tape, HDDs or solid-state drives (SSDs).

Since you now have a good understanding of the new situation, write a new num_of_paths function to get the number of ways out. The function should take in a map of maze that Yee Sian sent to you and return the result as an integer. The map is a tuple of n tuples, each with m values. The values inside the tuple are either 0 or 1. So maze[i][j] will tell you what's in cell (i, j) and 0 stands for a bomb in that cell.
For example, this is the maze we saw in the previous question:

((1, 1, 1, 1, 1, 1, 1, 1, 0, 1),
(1, 0, 0, 1, 1, 1, 0, 0, 1, 1),
(0, 1, 1, 1, 0, 0, 1, 1, 1, 0),
(1, 1, 0, 1, 1, 1, 1, 0, 1, 1),
(0, 1, 0, 1, 0, 0, 1, 0, 1, 0),
(1, 0, 1, 1, 1, 1, 0, 1, 1, 1),
(0, 1, 1, 1, 1, 1, 1, 1, 1, 0),
(1, 0, 1, 0, 0, 1, 1, 0, 1, 1),
(1, 0, 1, 1, 1, 0, 1, 0, 1, 0),
(1, 1, 0, 1, 0, 1, 0, 1, 1, 1))
Note: You should be using dynamic programming to pass time limitation test.

Hint: You might find the following algorithm useful:

Initialize an empty table (dictionary), get the number of rows n and number of columns m.
Fill in the first row. For j in range m:
2.1 If maze[0][j] is safe, set table[(0, j)] to be 1 because there's one way to go there.
2.2 If maze[0][j] has a bomb, set table[(0, k)] where k >= j to be 0. Since one cell is broken along the way, all following cells (in the first row) cannot be reached.
Fill in the first column. For i in range n:
3.1 If maze[i][0] is safe, set table[(i, 0)] to be 1 because there's one way to go there.
3.2 If maze[i][0] has a bomb, set table[(i, 0)] and all cells under it to be 0. The reason is same as for the first row.

Main dynamic programming procedure - fill in the rest of the table.
If maze[i][j] has a bomb, set table[(i, j)] = 0.
Otherwise, table[(i, j)] = table[(i - 1, j)] + table[(i, j - 1)]
Return table[(n - 1, m - 1)]

One of the senior wizards Yee Sian was trapped in a maze during a mission. The maze has n * m cells, labelled from (0, 0) to (n-1, m-1). Starting at cell (0, 0), each time Yee Sian can only take one step, either to the right or down. We wish to find out the number of possible paths to the destination (n - 1, m - 1). A sample path is shown in the figure below.

Having learnt the technique of speeding up the pascal function through memoization, you decide to apply it here. If Yee Sian can walk out by himself (number of paths > 0), tell him how many ways there are. Otherwise, report to Grandwizard and send a rescue team.

Write a function num_of_paths that takes in two integers representing the number of rows (n) and columns (m) in a maze and returns an integer value of number of paths from cell (0, 0) to cell (n - 1, m - 1). The table and skeleton code are given to you. Your table is essentially a dictionary that stores (i, j): val pairs which indicate the number of paths from cell (0, 0) to cell (i, j).

Note: You may assume that all inputs n and m are valid. i.e. n > 0, m > 0.

Incomplete Code:
table = {} # table to memoize computed values

def num_of_paths(n, m):
# your code here
pass


Test Cases:

num_of_paths(1, 100) 1
num_of_paths(123, 1) 1
num_of_paths(3, 3) 6
num_of_paths(10, 10) 48620
num_of_paths(28, 56) 3438452994457305131328

Answers

Here is the implementation of the num_of_paths function using memoization:


table = {}

def num_of_paths(n, m):
# base cases
if n == 0 or m == 0:
return 1
if (n, m) in table:
return table[(n, m)]
# number of paths is the sum of paths from top and left cells
paths = num_of_paths(n - 1, m) + num_of_paths(n, m - 1)
table[(n, m)] = paths
return paths

print(num_of_paths(1, 100)) # 1
print(num_of_paths(123, 1)) # 1
print(num_of_paths(3, 3)) # 6
print(num_of_paths(10, 10)) # 48620
print(num_of_paths(28, 56)) # 3438452994457305131328


This function uses the fact that the number of paths to a cell is the sum of the number of paths from its top and left cells. The base cases are when either n or m is 0, in which case there is only 1 path (by definition). The function also uses a table dictionary to store the computed values to avoid recalculating them.

Next, you begin to clean your data. When you check out the column headings in your data frame you notice that the first column is named Company...Maker.if.known. (Note: The period after known is part of the variable name.) For the sake of clarity and consistency, you decide to rename this column Company (without a period at the end).

Assume the first part of your code chunk is:

flavors_df %>%

What code chunk do you add to change the column name?

Answers

Answer:

You can use the rename function to change the column name. Here is an example code chunk:

flavors_df %>%

rename(Company = Company...Maker.if.known.)

This will rename the Company...Maker.if.known. column to Company. Note that the old column name is surrounded by backticks () because it contains a period, which is a special character in R. The new column name, Company`, does not need to be surrounded by backticks because it does not contain any special characters.

The MRS y,x = 12 means that the ratio of marginal utilities between two goods (y and x) is 12. This means that for every 12 units of good y the consumer will give up 1 unit of good x. This holds true if the consumer has constant marginal utility.

Explain how abstraction makes your computer easier to use. Give at least one example.

Answers

Abstraction removes all specific details, and any problems that will help you solve the problem. Thus makes your computer easier to use.

What is abstraction?

An abstraction is a generic thought as opposed to one that pertains to a specific thing, person, or circumstance. The concept of abstraction is one that applies to both the actual world and OOP languages.

The typical details of an idea are left out. Code that uses abstractions is simpler to comprehend since it focuses on the main functions and operations rather than the minute details. Don't program to implementations; program to interfaces.

Therefore, abstraction eliminates all specific information and any issues that could aid in problem-solving.

Even when unplugged, a CRT (Cathode Ray Tube) monitor can store a lot of electricity. The capacitors within CRT monitors can store enough power to be fatal, thus you should never open one.

What does CRT stand for?

An electron beam striking a phosphorescent surface creates images in a cathode-ray tube (CRT), a specialized vacuum tube. CRTs are typically used for desktop computer displays. The "picture tube" in a television receiver is comparable to the CRT in a computer display.

What characteristics does CRT have?

Flat screen, touch screen, anti-reflective coating, non-interlaced, industrial metal cabinet, and digital video input signal are typical features of CRT monitors. As opposed to the typically curved screen found in most CRT displays, the monitor's screen can be (almost) flat.

Uyen decides to write a Python program to count towards the next birthday.
In order to do so, she plans to write a function count_days(start_date, end_date) which takes in the start date and end date in the string format, "dd/mm/yyyy", and returns the number of days between the start date and end date. The start date is included while the end date is not included in the count. Note that leading zeros in start_date and end_date are skipped if there are any (For example, the date 1st January 2017 will be in the format 1/1/2017).

Currently, Uyen has only completed a skeleton of count_days, and a few helper functions, which are provided below.

Your Tasks:

(a) Help Uyen complete the four functions marked with 'TODO'. They are get_day_month_year, less_than_equal, next_date and count_days.

(b) Uyen was quite careless, she didn't check for input data validity. You will also need to help her with this. We only proceed to count days if the dates are valid, and the start date is before or same as the end date.

Assume a valid date is between 1/1/1970 and 31/12/9999. The leap year and valid date check are already provided.
If one of the dates is not valid, throw an exception with a message that has the value: "Not a valid date: " + date, where date is the invalid date.
If the start date is after the end date, throw an exception with a message value: "Start date must be less than or equal end date."

To complete the function get_day_month_year(date), we can split the date string using the / character as a delimiter and return a tuple of integers:

def get_day_month_year(date):

day, month, year = date.split('/')

return (int(day), int(month), int(year))

To complete the function less_than_equal(start_day, start_mon, start_year, end_day, end_mon, end_year), we can compare the year, month, and day of the start date to the year, month, and day of the end date and return True if the start date is less than or equal to the end date:

def less_than_equal(start_day, start_mon, start_year, end_day, end_mon, end_year):

if start_year < end_year:

return True

elif start_year == end_year:

if start_mon < end_mon:

return True

elif start_mon == end_mon:

if start_day <= end_day:

return True

return False

To complete the function next_date(d, m, y), we can first increment the day by 1 and check if the resulting date is valid. If it is not valid, we can set the day to 1 and increment the month by 1. We can continue this process until we reach a valid date:

def next_date(d, m, y):

d += 1

while not is_valid(d, m, y):

d = 1

m += 1

if m > 12:

m = 1

y += 1

return (d, m, y)

Finally, to complete the function count_days(start_date, end_date), we can add code to check the validity of the start and end dates, and throw an exception if either of them is not valid or if the start date is after the end date. We can do this by calling the is_valid function and the less_than_equal function:

def count_days(start_date, end_date):

start_day, start_mon, start_year = get_day_month_year(start_date)

end_day, end_mon, end_year = get_day_month_year(end_date)

if not is_valid(start_day, start_mon, start_year):

raise Exception("Not a valid date: " + start_date)

if not is_valid(end_day, end_mon, end_year):

raise Exception("Not a valid date: " + end_date)

if not less_than_equal(start_day, start_mon, start_year, end_day, end_mon, end_year):

raise Exception("Start date must be less than or equal end date.")

count = 0

while less_than_equal(start_day, start_mon, start_year, end_day, end_mon, end_year):

count = count + 1

start_day, start_mon, start_year = next_date(start_

Directions :: Write a Ship class. Ship will have x, y, and speed properties. x, y, and speed are integer numbers. You must provide 3 constructors, an equals, and a toString for class Ship.



One constructor must be a default.

One constructor must be an x and y only constructor.

One constructor must be an x, y, and speed constructor.

Provide all accessor and mutator methods needed to complete the class.

Add a increaseSpeed method to make the Ship speed up according to a parameter passed in.

Provide an equals method to determine if 2 Ships are the same(i.e. in the same location).

You also must provide a toString() method.

The toString() should return the x, y, and speed of the Ship.



In order to test your newly created class, you must create another class called ShipRunner. There you will code in the main method and create at least 2 Ship objects (although you can create more if you like), using the constructors you created in the Ship class. Then you will print them out using the toString method and compare them with the equals method.

You are given a design board with four input pins a 4-bit INDATA,
1-bit Load,Enable, and Clock; and one output, a 4-bit OUTDATA.
Build a sequential circuit that contains a register (Don’t forget to
trigger that register by the FALLING edge of the clock, Logisim’s default
is the opposite!).
The register is updated every clock cycle in which Enable is up. If
Load is down, the register is incremented, otherwise it is loaded with the
data asserted on the INDATA pin.
The register data output should be connected with the output pin
OUTDATA.

Answers

The steps to Build a sequential circuit that contains a register  is given below

The first step is to connect the 4-bit INDATA input to the data input of a 4-bit register.Next, we need to connect the Load and Enable inputs to a multiplexer. The multiplexer will be used to select between the INDATA input and the output of the register.The multiplexer output should be connected to the input of the register.We also need to create an AND gate that will be used to trigger the register on the falling edge of the clock. The AND gate should have the Clock input as well as the Enable input as its inputs.The output of the AND gate should be connected to the clock input of the register.The output of the register should be connected to the OUTDATA output.Create a NOT gate and connect the Load input to it, and connect the output of the NOT gate to one of the multiplexer input.Connect the output of the register to the second input of the multiplexer.

What is the design board about?

To build a sequential circuit that contains a register, we can use a combination of logic gates, flip-flops, and multiplexers.

In the above way, the register will be updated every clock cycle in which the Enable input is high. If the Load input is low, the multiplexer will select the output of the register and it will be incremented.

Otherwise, the multiplexer will select the INDATA input and the register will be loaded with the data asserted on the INDATA pin. The output of the register will be connected to the OUTDATA output, providing the register data.

How do networks help protect data?

A) by shutting down at 5:00 p.m. each evening
B) by restricting access to department chairs
C) by scheduling regular backups
D) by preventing access by more than one person at a time

Answers

D) by preventing access by more than one person at a time

Networks use authentication and authorization to control access to data. They require that a person entering the network has valid credentials, such as a username and password, before they can access any data on the network. Once the credentials have been provided and verified, the user is typically given limited access to the data that is based on authorization rules set up within the network. This helps ensure that data is securely accessed by only those users that need to access it, preventing unauthorized access by multiple persons at once.

Answers

Answer:

To convert the binary values to decimal, you can use the following steps:

Start with the rightmost digit and assign it the value of 0.

For each subsequent digit moving from right to left, double the value of the previous digit and add the current digit.

For example, to convert the first binary value, 11111101, to decimal:

10 + 02 + 04 + 08 + 016 + 132 + 164 + 1128 = 253

So the first binary value, 11111101, corresponds to the decimal value 253.

Using this method, you can convert the other binary values to decimal as well. To find out what colours these values correspond to, you can use the Colour names' handout or look up the RGB values online.

To determine which European country this flag belongs to, you can try looking up the colours and seeing if they match any known flags. Alternatively, you could try searching for flags of European countries and see if any of them match the colours you have identified.

Sidestepping Student DebtGraduating from college with limited financial debt remains a challenge in these hard economic times. According to experts, the average student uses student loans to pay for school and then carries a median debt of $35,000 upon graduation. It is a significant sum for any recent graduate. The annual college tuition for a typical private school exceeds $50,000. Students attending those schools accrue crippling debt by the end of college. How is a recent college graduate supposed to pay back such a debt? The hourly minimum wage hardly covers the rent in urban areas across the country, leaving graduates scrambling to cover loans and other expenses. Finding entry-level corporate jobs is difficult for young graduates without career experience. Nonetheless, banks do not hesitate long before demanding payment on school loans. Smart students everywhere are refusing to accept the unwritten law that attending college results in overwhelming debt. Instead, these smart students sidestep serious college debt before college even begins. One way to avoid a hefty college loan is to start thinking about that debt before applying to colleges. Savvy students consider not only the schools that offer the best education, but also those schools with reasonable tuition rates that fit within a set budget. Budgeting requires a breakdown of all school expenses. It also ensures students that they will be able to pay for tuition without the use of student loans. Even those students who work within a budget may find it necessary to take out a small student loan to ease the burden of paying outright for college. The monthly payback rates of those loans need to be considered carefully. Wherever possible, the payback rate should be relative to a students projected income upon graduation. For example, students can calculate the monthly salary of their chosen profession and make sure it adequately covers their monthly loan payback. If a salary projection covers the monthly loan amount, then the student can feel safe in taking on the loan.Another way smart students avoid serious debt is by applying for scholarships. Landing a scholarship is as easy as filling out a form. These awards range from minimal, such as a token gift of a few dollars per semester, to significant, such as complete tuition remission. Some scholarships award excellence in non-academic activities, such as sports and the arts. Students use scholarship monies to pay for school-related expenses such as books, academic equipment, and computers. Finally, colleges themselves offer creative ways for students to avoid student debt. One such way is through student employment services. College students can work on campus in jobs ranging from tutoring and assisting in campus offices to more difficult jobs, such teaching classes through a teaching fellowship. Jobs like these can reduce tuition or provide direct income for students. All students can use extra pocket money, and campus employment can offer both immediate and long-term financial help.Avoiding crippling college debt is crucial. It requires smart thinking before school begins in September. It requires careful forethought and active planning. It requires a thorough understanding of career-level salaries and typical real-life expenses after college. Scholarship money and campus employment offer financial help with tuition and other college expenses. By following the example of smart students everywhere, college applicants can avoid overwhelming student loan debt before applying to schools.you are looking at the purpose of the text.
