Answer:

If the next of first is null then

TRUE.

else

FALSE.

Explanation:

The return type of the method operation is boolean so it can only return True or False.

What we are checking inside the method is that the next of the first is null or not.

If the next of the first is null then the method will return true otherwise it will return false.

This is full analysis of the method operation.

Named constants should be used when they serve to improve readability and understanding. T or F

prisoha [69]

The answer is true.

Let's say we are calculating the volume of a grain silo where the the width is a constant, but the height can be changed.

In our code we would calculate the volume using something like:

PI * (WIDTH / 2)^2 * height

The variables in all caps would be named constants. Using them makes the code more readable to other people than if we were to just use their values like:

3.14 * (145.75 / 2)^2 * height

spayn [35]

The best recommendation in the mentioned scenario would be a smart watch.

Answer: Option A.

Explanation:

The best device for a business owner who needs an access to chat as well as to be in touch with the home office would be a smart watch. A smart watch is similar to a mobile device, which is worn on a wrist and which has a touchscreen display.

The benefits of smart watch are numerous. It makes us updated about everything without using our smartphone. The smart watch will help the business owner to engage with others and to handle his work at the same time.

Assuming you can use infinite number of CPUS for performance improvements, what would be the maximum speed up when the paralleli

natita [175]

Answer:

correct option is D i.e. 20

Explanation:

Given data:

Parallelizable portion is given as 95%

so remaining will be serial portion i.e. 5%

we know that, for infinite number of cpus, maximum speed is calculated as

$v =\frac{1}{f}$

where f denote serial portion = 5% = 0.05

$v = \frac{1}{0.05}$

v = 20

hence so for serial portion of 5%, maximum speed is 20

correct option is D i.e. 20

Suppose you wish to develop a matrix-multiplication algorithm that is asymptotically faster than Strassen’s algorithm. Your algo

Kazeer [188]

Answer:

The number of subproblems are given as $T(n)=a*T(n/8)+\theta(n^2)$ while the value of T(n) to be less than S(n) is for 342.

Explanation:

The number of subproblems are given as

$T(n)=a*T(n/8)+\theta(n^2)$

Asymptotic running time for Strassen’s algorithm is $S(n)=\theta(n^{log(7)})$

Now, when a increases, number of subproblems determines the asymptotic running time of the problem and case 1 of master theorem applies. So, in worst case, asymptotic running time of the algorithm will be

$T(n)=\theta(n^{logb(a)})=\theta(n^{log8(a)})=\theta(n^{log_{2}(a^{1/3})})$

Now, for T(n) to be smaller than S(n)

$n^{loga^{1/3}}$

So,

$log(a^{(1/3)})$

So,

a=342
