Professor Gig A. Byte needs to store text made up of the characters A with frequency 6, B with frequency 2, C with frequency 3, D with frequency 2, and E with frequency 8. Professor Byte suggests using the variable length codes:
Character Code
A 1
B 00
C 01
D 10
E 0
The professor argues that these codes store the text in less space than that used by an optimal Huffman code. Is the professor correct?

Answers

Answer 1

Answer:

This is not true

Explanation:

The optimal Huffman code is used to encrypt and compress text files. It uses fixed-length code or variable-length code for encryption and compression of data.

The professor's character code is similar to Huffman's variable-length coding which uses variable length od binary digits to represent the word strings. The file size of the text file above is;

= 6 x 1 + 2 x 2 + 3 x 2 + 2 x 2 + 8 x 1 = 28 bits

This would be the same for both cases.

The encrypt would be the problem as the encoded and decoding of the characters B and E may cause an error.

How many permutations for a 7 characters in length string, which contains all following letters R, X, S, Y, T, Z, U, has either the string 'RXS' or string 'ZU' in the 7 characters string?

Answers

Answer:

Following are the solution to this question:

Explanation:

In the following forms, RXS can appear:  

[tex]R X S \_ \_ \_ \_[/tex] it may look like that really, [tex]4 \times 3 \times 2 \times 1[/tex] forms = 24 may construct the remainder of its letters.  

[tex]\_ R X S \_ \_ \_[/tex] it may look like that really,  [tex]4 \times 3 \times 2 \times 1[/tex] forms = 24 may construct the remainder of its letters.  

[tex]\_ \_ R X S \_ \_[/tex] it may look like that really, [tex]4 \times 3 \times 2 \times 1[/tex] forms = 24 may construct the remainder of its letters.  

[tex]\_ \_ \_ R X S \_[/tex] it may look like that really,  [tex]4 \times 3 \times 2 \times 1[/tex] forms = 24 may construct the remainder of its letters.  

[tex]\_ \_ \_ \_ R X S[/tex] it may look like that really,  [tex]4 \times 3 \times 2 \times 1[/tex] forms = 24 may construct the remainder of its letters.  

And we'll have a total of [tex]24 \times 5 = 120[/tex] permutations with both the string RXS.

In the following forms, UZ can appear:

[tex]U Z \_ \_ \_ \_\ _[/tex]  They can organize your remaining 5 characters through 5 categories! Procedures [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]

[tex]\_ UZ \_ \_ \_ \_[/tex] They can organize your remaining 5 characters through 5 categories! Procedures [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]

[tex]\_ \_ U Z \_ \_ \_[/tex]They can organize your remaining 5 characters through 5 categories! Procedures  [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]

[tex]\_ \_ \_ U Z \_ \_[/tex]They can organize your remaining 5 characters through 5 categories! Procedures  [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]

[tex]\_ \_ \_ \_ U Z \_[/tex] They can organize your remaining 5 characters through 5 categories! Procedures  [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]

[tex]\_ \_ \_ \_ \_ U Z[/tex] They can organize your remaining 5 characters through 5 categories! Procedures  [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]

There may be [tex]120 \times 6 = 720[/tex] ways of complete permutations.

/* Your solution goes here */
*numPtr1 = 44;
*numPtr2 = 99;
printf("numPtr1 = %d, numPtr2 = %d\n", *numPtr1, *numPtr2);
free(numPtr1);
free(numPtr2);
return 0;
}

Answers

Answer:

#include <stdio.h>

#include <stdlib.h>

int main(void) {

   int* numPtr1 = NULL;

   int* numPtr2 = NULL;

   /* Your solution goes here */

   numPtr1 = (int *) malloc(10);

   numPtr2 = (int *) malloc(20);

   *numPtr1 = 44;

   *numPtr2 = 99;

   printf("numPtr1 = %d, numPtr2 = %d\n", *numPtr1, *numPtr2);

   free(numPtr1);

   free(numPtr2);

   return 0;

}

Explanation:

The C library malloc function is used to assign memory locations (in bytes) to variables. It accepts the size parameter and returns a pointer to the specified variable location.

The two malloc statements above assign two memory locations 10 and 20 to the numPtr1 and numPtr2 integer variables respectively.

Explanation:

Write a recursive function that accepts two arguments into the parameters x and y. The function should return the value of x times y. Hint: multiplication can be performed as repeated addition. Test your recursive function by prompting the user to enter values for x and y and then displaying the result. Your function should be able to handle multiplication of negative values.

Answers

Answer:

In Python:

def times(x,y):

     if y<0:

           return -1*times(x,y*-1)

     if y == 1:

           return x

     return x + times(x,y-1)

x = int(input("x: "))

y = int(input("y: "))

print(times(x,y))

Explanation:

I answered the question using Python3

This defines the function

def times(x,y):

This checks for negative values

     if y<0:

           return -1*times(x,y*-1)

This is the base case where y = 1

     if y == 1:

If true, the value of x is returned

           return x

This returns the recursion and it is repeated until the base case is achieved

     return x + times(x,y-1)

This prompts user for x value

x = int(input("x: "))

This prompts user for y value

y = int(input("y: "))

This calls the recursion and also prints the result

print(times(x,y))

x=counter(numbers,SIZE,3); will put 4 into x.

Answers

Answer:

Explanation:

The following function is written in Java and takes in three parameters the array, its size, and the chosenNumber that will be counted. The function then creates an instance variable called Counter and loops through the given array looking for the chosenNumber. Every time that the number is found in the array it adds 1 to the counter. Once the loop is done it returns the total value of the counter variable.

 public static int counter(int[] numbers, int Size, int chosenNumber) {

       int counter = 0;

       for (int x = 0; x < Size; x++) {

           if(numbers[x] == chosenNumber) {

               counter++;

       }
