Your task is to implement a function replace_once(t, d), that takes a text t and a replacement dictionary d, and returns the res

ult of replacing words according to the dictionary: if a word appears as a key, replace it with the dictionary value, and if a word does not appear in the dictionary, leave it alone.
Given a list of words, you can concatenate them together with spaces in between as follows:
word_list = "I love eating bananas".split()
print("Word list:", word_list)
back_together = " ".join(word_list)
print("Back together:", back_together)
# You can also join them in other ways, btw. Just DON'T do it for this homework.
print("You can also put commas:", ", ".join(word_list))

Answer:

Explanation:

The following code is written in Python and does exactly as requested. It is a function named replace_one(t, d) that takes the two parameters one text/word and one dictionary. If the word is found as a key in the dictionary it places the value in a variable called new_word and returns it to the user, if it is not found then the function returns nothing.

def replace_once(t, d):

   if t in d:

       new_word = d.get(t)

       return new_word

   return

A cache has been designed such that it has 512 lines, with each line or block containing 8 words. Identify the line number, tag,
Reptile [31]

Answer:

Given address = 94EA6_{16}

tag = 0 * 94  ( 10010100 )

line = 0 * 1 D 4 ( 111010100 )

word position = 0*6 ( 110 )

Explanation:

using the direct mapping method

Number of lines = 512

block size = 8 words

word offset = log ^{8} _{2}  = 3 bit

index bit = log^{512}_{2}  = 9 bit

Tag = 20 - ( index bit + word offset ) = 20 - ( 3+9) = 8 bit

Given address = 94EA6_{16}

tag = 0 * 94  ( 10010100 )

line = 0 * 1 D 4 ( 111010100 )

word position = 0*6 ( 110 )

What are the limits of hashing and verifying that files haven’t changed?
earnstyle [38]

The hashing function can take any number of key-value pairs and there is no specific limit to it.

<h3>What is hashing?</h3>

Hashing is a file-based algorithm for producing a fixed-length bit string value. A file is essentially a collection of data blocks. The length of the data is reduced by hashing to a fixed number or key that represents the original string.

When hashing is employed, the hash function may plot all of the keys and values to what the real size of the table is, demonstrating that the hashing function can take any number of key-value pairs with no restriction.

However, if the passwords are hashed in encryption, recovering the passwords is extremely difficult.

Thus, the hashing function can take any number of key-value pairs and there is no specific limit to it.

Write a program that has an input as a test score, and figures out a letter grade for that score, such as "A", "B", "C", etc. ac
Marizza181 [45]

Answer:

The program in csharp for the given scenario is shown.

using System;

class ScoreGrade {

static void Main() {

//variables to store score and corresponding grade

double score;

char grade;

//user input taken for score

Console.Write("Enter the score: ");

score = Convert.ToInt32(Console.ReadLine());

//grade decided based on score

if(score>=90)

grade='A';

else if(score>=80 && score<90)

grade='B';

else if(score>=70 && score<80)

grade='C';

else if(score>=60 && score<70)

grade='D';

else

grade='F';

//score and grade displayed  

Console.WriteLine("Score: "+score+ " Grade: "+grade);

}

}

OUTPUT1

Enter the score: 76

Score: 76 Grade: C

OUTPUT2

Enter the score: 56

Score: 56 Grade: F

Explanation:

1. The variables to hold the score and grade are declared as double and char respectively.

int score;

char grade;

2. The user is prompted to enter the score. The user input is not validated and the input is stored in the variable, score.

3. Using if-else-if statements, the grade is decided based on the value of the score.

if(score>=90)

grade='A';

else if(score>=80 && score<90)

grade='B';

else if(score>=70 && score<80)

grade='C';

else if(score>=60 && score<70)

grade='D';

else

grade='F';

4. The score and the corresponding grade are displayed.

5. The program can be tested for different values of score.

6. The output for two different scores and two grades is included.

7. The program is saved using ScoreGrade.cs. The .cs extension indicates a csharp program.

8. The whole code is written inside a class since csharp is a purely object-oriented language.

9. In csharp, user input is taken using Console.ReadLine() which reads a string.

10. This string is converted into an integer using Convert.ToInt32() method.

score = Convert.ToInt32(Console.ReadLine());

11. The output is displayed using Console.WriteLine() or Console.Write() methods; the first method inserts a line after displaying the message which is not done in the second method.

12. Since the variables are declared inside Main(), they are not declared static.

13. If the variables are declared outside Main() and at the class level, it is mandatory to declare them with keyword, static.
