Answer:

The data in web storage is passed to the server with every HTTP request.

Explanation:

There are basically two Web storage APIs Session storage and local storage.Both can store data up to 5MB. They are supported by every modern browser.You can store data in local storage indefinitely and for browser session in session storage.There is no data or information in HTTP request header.So we conclude that option 4 is the answer.

Answer:

To allow user to assign rating

Explanation:

The basic function of “rate” command is to give opportunity to the user to assign a value to a song from the range of 1 – 5.

In the range, the value of 1 indicates the lowest rating, while value of 5 is the highest rating that can be obtained.

Any previous ratings are then replaced by the new rating assigned from the range of 1 – 5.

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

Recursively computing the sum of the first n positive odd integers, cont. About (a) Use induction to prove that your algorithm t

julia-pushkina [17]

The recursive function would work like this: the n-th odd number is 2n-1. With each iteration, we return the sum of 2n-1 and the sum of the first n-1 odd numbers. The break case is when we have the sum of the first odd number, which is 1, and we return 1.

int recursiveOddSum(int n) {

if(2n-1==1) return 1;

return (2n-1) + recursiveOddSum(n-1);

}

To prove the correctness of this algorithm by induction, we start from the base case as usual:

$f(1)=1$

by definition of the break case, and 1 is indeed the sum of the first odd number (it is a degenerate sum of only one term).

Now we can assume that $f(n-1)$ returns indeed the sum of the first n-1 odd numbers, and we have to proof that $f(n)$ returns the sum of the first n odd numbers. By the recursive logic, we have

$f(n)=f(n-1)+2n-1$

and by induction, $f(n-1)$ is the sum of the first n-1 odd numbers, and 2n-1 is the n-th odd number. So, $f(n)$ is the sum of the first n odd numbers, as required:

$f(n)=\underbrace{\underbrace{f(n-1)}_{\text{sum of the first n-1 odds}}+\underbrace{2n-1}_{\text{n-th odd}}}_{\text{sum of the first n odds.}}$

zvonat [6]

Answer:

The replacement of traditional mainframe and minicomputers is a prime example of technological paradigm shift.

Explanation:

As the change of traditional mainframe and minicomputers to personal computers is due to the technological advancements, which led to creation of client server networks. This paradigm shift is the technological shift as the main reason for the shift is due to the technical advancement and enhancement.
