a password to a certain database consists of digits that cannot be repeated. if the password is known to consist of at least 8 d

BaLLatris [955]

Answer:

$\frac{10!}{2}mins$

Explanation:

12 seconds to try one combination will be equivalent to $\frac{1}{12}\times 60 = \frac{1}{5} \ mins$

Password contain at least 8 digit i.e. password can contain 8, 9, 10 digit.

Password cannot contain more than 10 digit because it will give room for repetition which it is clearly stated that digit cannot be repeated.

Possible digit that can be used: 9,8,7,6,5,4,3,2,1,0.

Total number of passwords combination possible for each position in 8 digit.

1st position = 10, 2nd position = 9, 3rd position = 8, 4th position = 7, 5th position = 6, 6th position = 5, 7th position = 4, 8th position = 3. Total number of passwords combination possible in 8 digit is equivalent to $\frac{10!}{2}$ .

Total number of passwords combination possible for each position in 9 digit.

1st position = 10, 2nd position = 9, 3rd position = 8, 4th position = 7, 5th position = 6, 6th position = 5, 7th position = 4, 8th position = 3, 9th position = 2. Total number of passwords combination possible in 9 digit is equivalent to $\frac{10!}{1}$ .

Total number of passwords combination possible for each position in 10 digit.

1st position = 10, 2nd position = 9, 3rd position = 8, 4th position = 7, 5th position = 6, 6th position = 5, 7th position = 4, 8th position = 3, 9th position = 2, 10th position = 1. Total number of passwords combination possible in 10 digit is equivalent to 10!.

Adding them up and multiplying by $\frac{1}{5} \ mins$ to get the total number of time needed to guarantee access to database = $[\frac{10!}{2}\times\ \frac{10!}{1} \times 10!] \frac{1}{5}\ mins = \frac{10!}{2}$

circular_prime A number is called a circular prime if all rotations of its digits form a prime. For example, the number 197 is a

Lilit [14]

Answer:

function out=circular_primes(no)

prim=primes(no);% find the all prime number till the given number

pr=0;

nos=[];

po=[];

for p=1:length(prim)

n=prim(p); % picking up each prime no one by one

n=num2str(n);% change into string for rotation of no

d=length(n); % length of string

if d>1 % take nos greater than 10 beacuase below 10 no need for rotation

for h=1:d

a=n(1);

for r=1:d % for rotation right to left

if r==d 5 % for the last element of string

n(d)=a;

else

n(r)=n(r+1); %shifting

end

s=str2num(n); % string to number

nos=[nos,s]; % store rotated elements in array

end

if nos(end)==no %if given no is also a circular prime we need smaller

break;

end

for gr=1:length(nos) % checking rotated nos are prime or not

p1=isprime(nos(gr));

po=[po,p1]; %storing logical result in array

end

if sum(po(:))==length(nos) %if all are prime the length and sum are must be equal

pr=pr+1;

out=pr;

else

out=pr;

end

po=[];

nos=[];

else

s=str2num(n); %numbers less than 10

f=isprime(s);

if f==1

pr=pr+1;

out=pr;

else

out=pr;

end

In this lab, you create a programmer-defined class and then use it in a C++ program. The program should create two Rectangle obj

MakcuM [25]

The program based on the information given is illustrated below.

<h3>What is a program?</h3>

A computer program simply means a sequence of instructions in a programming language that is created for a computer to execute.

It should be noted that computer programs are among the component of software.

The program to create two rectangle objects and get their area and perimeter is depicted:

// Rectangle.cpp

using namespace std;

class Rectangle

{

public:

// Declare public methods here

void setLength(double);

void setWidth(double);

double getLength();

double getWidth();

double calculateArea();

double calculatePerimeter();

private:

// Create length and width here

double length, width;

};

void Rectangle::setLength(double len)

{

length = len;

}

void Rectangle::setWidth(double wid)

{

// write setWidth here

width = wid;

}

double Rectangle::getLength()

{

// write getLength here

return length;

}

double Rectangle::getWidth()

{

// write getWidth here

return width;

}

double Rectangle::calculateArea()

{

// write calculateArea here

return length*width;

}

double Rectangle::calculatePerimeter()

{

// write calculatePerimeter here

return 2*(length+width);

}

// This program uses the programmer-defined Rectangle class.

#include "Rectangle.cpp"

#include <iostream>

using namespace std;

int main()

{

Rectangle rectangle1;

Rectangle rectangle2;

rectangle1.setLength(10.0);

rectangle1.setWidth(5.0);

rectangle2.setLength(7.0);

rectangle2.setWidth(3.0);

cout << "Perimeter of rectangle1 is " << rectangle1.calculatePerimeter() << endl;

cout << "Area of rectangle1 is " << rectangle1.calculateArea() << endl;

cout << "Perimeter of rectangle2 is " << rectangle2.calculatePerimeter() << endl;

cout << "Area of rectangle2 is " << rectangle2.calculateArea() << endl;

return 0;

}

/*

output:

The perimeter of rectangle1 is 30

The area of rectangle1 is 50

The Perimeter of rectangle2 is 20

The area of rectangle2 is 21

*/
