Consider the following 3-PARTITION problem. Given integers a1; : : : ; an, we want to determine whether it is possible to partit

ion of f1; : : : ; ng into three disjoint subsets I; J;K such that X i2I ai = X j2J aj = X k2K ak = 1 3 Xn i=1 ai For example, for input (1; 2; 3; 4; 4; 5; 8) the answer is yes, because there is the partition (1; 8), (4; 5), (2; 3; 4). On the other hand, for input (2; 2; 3; 5) the answer is no. Devise and analyze a dynamic programming algorithm for 3-PARTITION that runs in time polynomial in n and in P i ai.

Answer:

The data can be safeguarded using key escrow procedure.

Explanation:

Key escrow basically means to store the cryptographic key in an "escrow" by a reputable trusted third party. The copy of the encryption key is kept with the third party. In case the cryptographic key gets lost or destroyed, then the key escrow service helps to access the encrypted data. It also manages the access control to the key in case the key gets lost. So this way in case of security breach at GearOn the key escrow service can be used to re-implement or access the key easily.

worty [1.4K]

Answer:

The program to this question as follows:

Program:

//header file

#include <iostream> //defining header file

using namespace std;

void printFeetInchShort(int numFeet,int numInches); //decalring method printFeetInchShort  

void printFeetInchShort(int numFeet,int numInches)//defining method printFeetInchShort

{

cout<<"height: "; // print message

cout<<numFeet<<"\'"<<""<<numInches<<"\""; //print value

}

int main() //defining main method

{

int numFeet, numInches; //defining integer variable

cout<<"Enter height feet: "; //print message

cin>>numFeet; //input value by user

cout<<"Enter height inches: "; //print message

cin>>numInches; //input value by user

printFeetInchShort(numFeet,numInches); //calling method printFeetInchShort    

return 0;

}

Output:

Enter height feet: 5

Enter height inches: 9

height: 5'9"

Explanation:

In the above C++ language program, first, a header file is included, that uses the basic function, in the next step, the "printFeetInchShort()" method is defined, in the method two integer variables passed as a parameter, inside this method a print function "cout" is used, that print user input value with single and double quote.

Feliz [49]

Answer:

Joyner

David

USA

1.8

30

Explanation:

def saveUserProfile(firstName, lastName, age, height, country):

This is the definition of function named saveUserProfile which accepts the following parameters:

  • firstName
  • lastName
  • age
  • height
  • country

filename = lastName + firstName + ".txt"

When the file is created it will be named as the lastName and firstName string combined with .txt as extension. For example if the lastName contains the name string Joyner and firstName contains the name David then the file created to be written is named as JoynerDavid.txt

outputFile = open(filename, "w")

This statement uses open() method in write mode and uses outputFile object to access the file. "w" represents write mode i.e. file is opened in write mode to write on it.

a) Joyner is written on line 1 of that file because of the following statement of above function:

print(lastName, file = outputFile)

This statement prints the string stored in lastName i.e. Joyner. Here outputFile opens the file in "w" write mode and writes the last name to the first line of the file.

b) David is written on line 2 of that file because of the following statement of above function:

print(firstName, file = outputFile)

This statement prints the string stored in firstName i.e. David. Here outputFile opens the file in "w" write mode and writes the first name to the second line of the file.

c) USA is written on line 3 of that file because of the following statement of above function:

print(country, file = outputFile)

This statement prints the data stored in country i.e. USA. Here outputFile opens the file in "w" write mode and writes the country name to the third line of the file.  

d) 1.8 is written on line 4 of that file because of the following statement of above function:

print(height, file = outputFile)

This statement prints the value stored in height i.e. 1.8. Here outputFile opens the file in "w" write mode and writes the height value to the fourth line of the file.  

e) 30 is written on line 5 of that file because of the following statement of above function:

print(age, file = outputFile)

This statement prints the value stored in age parameter of function saveUserProfile i.e. 30. Here outputFile opens the file in "w" write mode and writes the age value to the fifth line of the file.
