Fill in the blanks to make the factorial function return the factorial of n. Then, print the first 10 factorials (from 0 to 9) w
nadezda [96]

Answer:

Following are code of factorial in python language

def factorial(n): # function

   result=1 #variable

   for x in range(2,n+1): #iterating the loop

       result=result*x  #storing result

   return result #return result

for n in range(10): #iterating loop

   print(n,factorial(n)) #print factorial

Output:

Following are the attachment of output

Explanation:

Missing information :

In the question the information is missing the code is missing which we have to correct it following are the code that are mention below.

def factorial(n): # function

   result=1 #variable

   for x in range(       ): #iterating the loop

       result=  #storing result

   return  #return result

for n in range(  ): #iterating loop

   print(n,factorial(n)) #print factorial

Following are the description of code

  • We have create a function factorial  in this we have pass the one parameter i.e "n".
  • In the for loop we have pass 2,n+1 which has been used to iterating the loop calculating factorial and string the result in the result variable
  • In the main function we have pass the range on which we have to calculated the factorial
  • Finally the print function will print the factorial .

Following are the attachment snip of code in the python language

- Consider the relation R = {A, B, C, D, E, F, G, H, I, J} and the set of functional dependencies F = { {B, C} -> {D}, {B} -&
Olenka [21]

Answer:

The key of R is {A, B}

Explanation:

A key can be seen as a minimal set of attributes whose closure includes all the attributes in R.

Given that the closure of {A, B}, {A, B}+ = R, one key of R is {A, B} But in this case, it is the only key.

In order for us to to normalize R intuitively into 2NF then 3NF, we have to make use of these approaches;

First thing we do is to identify partial dependencies that violate 2NF. These are attributes that are

functionally dependent on either parts of the key, {A} or {B}, alone.

We can calculate

the closures {A}+ and {B}+ to determine partially dependent attributes:

{A}+ = {A, D, E, I, J}. Hence {A} -> {D, E, I, J} ({A} -> {A} is a trivial dependency)

{B}+ = {B, F, G, H}, hence {A} -> {F, G, H} ({B} -> {B} is a trivial dependency)

To normalize into 2NF, we remove the attributes that are functionally dependent on

part of the key (A or B) from R and place them in separate relations R1 and R2,

along with the part of the key they depend on (A or B), which are copied into each of

these relations but also remains in the original relation, which we call R3 below:

R1 = {A, D, E, I, J}, R2 = {B, F, G, H}, R3 = {A, B, C}

The new keys for R1, R2, R3 are underlined. Next, we look for transitive

dependencies in R1, R2, R3. The relation R1 has the transitive dependency {A} ->

{D} -> {I, J}, so we remove the transitively dependent attributes {I, J} from R1 into a

relation R11 and copy the attribute D they are dependent on into R11. The remaining

attributes are kept in a relation R12. Hence, R1 is decomposed into R11 and R12 as

follows: R11 = {D, I, J}, R12 = {A, D, E} The relation R2 is similarly decomposed into R21 and R22 based on the transitive

dependency {B} -> {F} -> {G, H}:

R2 = {F, G, H}, R2 = {B, F}

The final set of relations in 3NF are {R11, R12, R21, R22, R3}

finlep [7]
#1) An important task that the operating system performs is ____, which keeps track of the files stored on a computer so that they can be retrieved when needed.
Answer: File Management System. Keeps track of where files are stored and determines how the files are stored following the operating system file allocation policies. It uses available storage space efficiently for files and creates a record/log of all file usage. It allocates a file to a user if is free, and if they are permitted access to it. Then de-allocates file when the user is finished with it.
