Answer 1

Answer:

The correction is as follows:

(a)

small = arr[0];

for (int j = 0; j < arr.length; j++){

if (small > arr[j]) {

small = arr[j]; } }

(b)

double sum = 0;

int n = arr.length;

for (int k = arr.length-1; k >= 0; k--)

sum = sum + arr[k];

double avg = sum /n;

(c)

int[] a = {1,2,3,4,5};

int[] b = new int[5];

for (int i=0; i<a.length; i++)

b[i] = a[a.length-i-1];

Explanation:

Required

Correct each of the given code

This line is correct; it initializes the smallest to the first element

small = arr[0];

This iterates through the array; however, the last element is left out.

for (int j = 0; j < arr.length-1; j++)

So, the correct code is: for (int j = 0; j < arr.length; j++){

The expected remaining part of the program which compares the elements of the array is missing

I've completed the code [See the answer section]

By syntax this line is correct. However, for the average to be calculated as double; sum has to be declared as double

int sum = 0;

So, the correct code is: double sum = 0;

This line correctly calculates the length of the array

int n = arr.length;

This iteration will create an endless loop

for (int k = arr.length; k <= 0; k--)

So, the correct code is: for (int k = arr.length-1; k >= 0; k--)

This correctly add up the elements of the array

sum = sum + arr[k];

This correctly calculate the average of the array elements

double avg = sum /n;

(c)

The array a is incorrectly initialized because there is no matching end curly brace

int[] a = {1,2,3,4,5);

So, the correct code is: int[] a = {1,2,3,4,5};

This correctly create array b with 5 elements

int[] b = new int[5];

This iterates through a; however, the last element is left out

for (int i=0; i<=a.length; i++)

So, the correct code is: for (int i=0; i<a.length; i++)

This will create an out of bound error

b[i-1] = a[a.length-i];

So, the correct code is: b[i] = a[a.length-i-1];

**GIVING ALL POINTS** 4.02 Coding With Loops
I NEED THIS TO BE DONE FOR ME AS I DONT UNDERSTAND HOW TO DO IT. THANK YOU

Output: Your goal

You will complete a program that asks a user to guess a number.

Part 1: Review the Code

Review the code and locate the comments with missing lines (# Fill in missing code). Copy and paste the code into the Python IDLE. Use the IDLE to fill in the missing lines of code.

On the surface this program seems simple. Allow the player to keep guessing until he/she finds the secret number. But stop and think for a moment. You need a loop to keep running until the player gets the right answer.

Some things to think about as you write your loop:

The loop will only run if the comparison is true.

(e.g., 1 < 0 would not run as it is false but 5 != 10 would run as it is true)

What variables will you need to compare?

What comparison operator will you need to use?

# Heading (name, date, and short description) feel free to use multiple lines

def main():

# Initialize variables

numGuesses = 0

userGuess = -1

secretNum = 5

name = input("Hello! What is your name?")

# Fill in the missing LOOP here.

# This loop will need run until the player has guessed the secret number.

userGuess = int(input("Guess a number between 1 and 20: "))

numGuesses = numGuesses + 1

if (userGuess < secretNum):

print("You guessed " + str(userGuess) + ". Too low.")

if (userGuess > secretNum):

print("You guessed " + str(userGuess) + ". Too high.")

# Fill in missing PRINT statement here.

# Print a single message telling the player:

# That he/she guessed the secret number

# What the secret number was

# How many guesses it took

main()

Part 2: Test Your Code

Use the Python IDLE to test the program.

Using comments, type a heading that includes your name, today’s date, and a short description.

Run your program to ensure it is working properly. Fix any errors you observe.

Example of expected output: The output below is an example of the output from the Guess the Number game. Your specific results will vary based on the input you enter.

Output

Your guessed 10. Too high.

Your guessed 1. Too low.

Your guessed 3. Too low.

Good job, Jax! You guessed my number (5) in 3 tries!

When you've completed filling in your program code, save your work by selecting 'Save' in the Python IDLE.

When you submit your assignment, you will attach this Python file separately.

Part 3: Post Mortem Review (PMR)

Using complete sentences, respond to all the questions in the PMR chart.

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)]

MTBF is a measurement of

A) the speed at which a storage device can read and write data
B) the number of digits used to store a computer file
C) the average length of a time a storage device can reliably hold data without it beginning to degrade
D) the average length of time between failures on a device

Answers

MTBF is a measurement of the average length of time between failures on a device. Thus, the correct option for this question is D.

What is MTBF in computers?

MTBF stands for Mean time between failures. It is often utilized in order to measure the overall failure rates, for both repairable and replaceable/non-repairable products.

It governs the simplest equation for mean time between failure. It is as follows:

MTBF = total operational uptime between failures/number of failures.

It is the predicted elapsed time between inherent failures of a mechanical or electronic system during the normal functioning of the computer system in order to detect an error.

Therefore, MTBF is a measurement of the average length of time between failures on a device. Thus, the correct option for this question is D.

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.

A software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications. There are six (6) main stages in the creation of a software and these are;

1. Planning.

2. Analysis.

3. Design.

4. Development (coding).

5. Deployment.

6. Maintenance.

One of the most important steps in the software development life cycle (SDLC) is design. It is the third step of SDLC and comes immediately after the analysis stage.

Basically, method design is the stage where the software developer describes the features, architecture and functions of the proposed solution in accordance with a standard.

Software architecture can be defined as the software blueprint or infrastructure in which the components (elements) of the software providing user functionality and their relationships are defined, deployed and executed. Thus, it is a structured framework used by software developers to model software components (elements), properties and relationships in order to have a good understanding of how the program would behave.

In conclusion, software architecture doesn't dictate the process used by a team to develop use cases for a software system.

Answers

Below is a simple flowchart that shows the process of calculating the volume of an object using its mass and density:

+-----------------------------+

| Input: Mass (m), |

| Density (d) |

+-----------------------------+

| Volume = Mass / Density |

+-----------------------------+

| Output: Volume (v) |

+-----------------------------+

What is the Flowchart about?

The flowchart I provided shows the basic process of calculating the volume of an object using its mass and density. The process starts with the input of the object's mass and density. The mass is typically given in grams and the density is given in grams per cubic centimeter.

The next step is to calculate the volume of the object. This is done by using the formula for density, which states that density is equal to mass divided by volume. So, to find the volume, we divide the mass of the object (in grams) by its density (in grams per cubic centimeter). This formula can be written as:

volume = mass / density

Finally, the calculated volume is then output, which is typically given in cubic centimeters.

Note that:

density = mass/volume.

Density = mass / volume

Explanation:

If an image has only 4 colors, how many bits are necessary to represent one pixel’s color? Describe a new custom encoding that uses fewer bits to represent each color in the image. What is your encoding for each color? If you were to re-encode this image using your new encoding, how many bits would you save when compared to the 24 bit RGB encoding?

Answers

Answer:

1) 2 bits 2) shown in explanation 3) shown in explanation 4) 22 bits per pixel (2.75 bytes)

Explanation:

As a bit is one of two states, 1 or 0, 2 bits is sufficient to represent 4 colors:

00 = color 1

01 = color 2,

10 = color 3,

11 = color 4

This would be the custom type of encoding for that specific image as it only uses 4 colors.

Now to calculate the amount of memory saved, which is quite simple:

24-2=22

So you Would save 22 bits per pixel or 2.75 bytes per pixel.

RGB is a colour complementary wherein the main light colors of red, green, and blue are coupled in distinct ways of representing a range of colors. It uses to design is named again for preliminary colors red, blue and green of 3 primary additive color schemes.

Following are the solution to the given question:

Calculating the number of total bits which is required:

[tex]\bold{= \log_2\ \text{(total number of colors)}}\\\\\bold{= \log_2\ (4)}\\\\\bold{= 2}[/tex]

Because only 4 colors seem to be prevalent, we could have the very next global color encoding:

[tex]\to \bold{ Black = 00}\\\\\to \bold{White= 01}\\\\\to \bold{Red= 10}\\\\\to \bold{Blue= 11}\\[/tex]

So, the number of total bits through the image:

[tex]\to \bold{= (17 \times 20) \times 24} \ \bold{= 8160}[/tex]

The number of total bits for the picture now is custom encoded

[tex]\to \bold{= (17 \times 20) \times 2} \ \bold{= 680}[/tex]

Calculating the percentage:

[tex]\bold{= \frac{\text{(original bits - new bits)} \times 100}{\text{original bits}}}\\\\\bold{= \frac{(8160 - 680) \times 100}{8160}}\\\\\bold{= \frac{7480 \times 100}{8160}}\\\\\bold{= \frac{748000}{8160}}\\\\\bold{= 91.67\%}[/tex]

So, the final answer is "2,00,01,10,11, and 91.67%"

which component of cpu controls the overall operation of computer..

Answers

Answer:

Control unit.

Explanation:

A scheduling computer system refers to an ability of the computer that typically allows one process to use the central processing unit (CPU) while another process is waiting for input-output (I/O), thus making a complete usage of any lost central processing unit (CPU) cycles in order to prevent redundancy.

Modern central processing units (CPUs) only require a few nanoseconds to execute any instruction when all operands are stored in its registers.

In terms of the scheduling metrics of a central processing unit (CPU), the time at which a job completes or is executed minus the time at which the job arrived in the system is known as turnaround time.

Generally, it is one of the scheduling metrics to select for optimum performance of the central processing unit (CPU).

The component of the central processing unit (CPU) that controls the overall operation of a computer is the control unit. It comprises of circuitry that makes use of electrical signals to direct the operations of all parts of the computer system. Also, it instructs the input and output device (I/O devices) and the arithmetic logic unit how to respond to informations sent to the processor.

You had learnt how to create the Pascal Triangle using recursion.

def pascal(row, col):
if col == 1 or col == row:
return 1
else:
return pascal(row - 1, col) + pascal(row - 1, col - 1)

But there is a limitation on the number of recursive calls. The reason is that the running time for recursive Pascal Triangle is exponential. If the input is huge, your computer won't be able to handle. But we know values in previous rows and columns can be cached and reused. Now with the knowledge of Dynamic Programming, write a function faster_pascal(row, col). The function should take in an integer row and an integer col, and return the value in (row, col).
Note: row and col starts from 1.

Test Cases:
faster_pascal(3, 2) 2
faster_pascal(4, 3) 3
faster_pascal(100, 45) 27651812046361280818524266832
faster_pascal(500, 3) 124251
faster_pascal(1, 1) 1

Answers

def faster_pascal(row, col):

if (row == 0 or col == 0) or (row < col):

return 0

arr = [[0 for i in range(row+1)] for j in range(col+1)]

arr[0][0] = 1

for i in range(1, row+1):

for j in range(1, col+1):

if i == j or j == 0:

arr[i][j] = 1

else:

arr[i][j] = arr[i-1][j] + arr[i-1][j-1]

return arr[row][col]

Here is a solution using dynamic programming:

def faster_pascal(row, col):
# Create a list of lists to store the values
values = [[0 for i in range(row+1)] for j in range(row+1)]

# Set the values for the base cases
values[0][0] = 1
for i in range(1, row+1):
values[i][0] = 1
values[i][i] = 1

# Fill the rest of the values using dynamic programming
for i in range(2, row+1):
for j in range(1, i):
values[i][j] = values[i-1][j-1] + values[i-1][j]

# Return the value at the specified row and column
return values[row][col]

Here is how the algorithm works:

1-We create a list of lists called values to store the values of the Pascal Triangle.
2-We set the base cases for the first row and column, which are all 1s.
3-We use a nested loop to fill the rest of the values using dynamic programming.
We use the values in the previous row and column to calculate the current value.
4-Finally, we return the value at the specified row and column.

What is output by the following code? c = 1 sum = 0 while (c < 10): c = c + 2 sum = sum + c print (sum)

Answers

With the given code, The code outputs 24.

How is this code run?

On the first iteration, c is 1 and sum is 0, so c is incremented to 3 and sum is incremented to 3.

On the second iteration, c is 3 and sum is 3, so c is incremented to 5 and sum is incremented to 8.

On the third iteration, c is 5 and sum is 8, so c is incremented to 7 and sum is incremented to 15.

On the fourth iteration, c is 7 and sum is 15, so c is incremented to 9 and sum is incremented to 24.

At this point, c is no longer less than 10, so the while loop exits and the final value of sum is printed, which is 24.
