What is the output?
olga55 [171]

Answer:

The output is 28

Explanation:

Required

Determine the output of the code segment

The first line initializes "answer" to 0

The next two lines iterate through lists [2,4] and [3,5

Each of these lists have two elements; So, the number of iterations is 2 * 2 i.e. 4.

In the first iteration

numA = 2, numB = 3, answer = 0

So:

answer = answer + numA + numB= 0 + 2 + 3 = 5

In the second iteration

numA = 2, numB = 5, answer = 5

So:

answer = answer + numA + numB= 5 + 2 + 5 = 12

In the third iteration

numA = 4, numB = 3, answer = 12

So:

answer = answer + numA + numB= 12 + 4 + 3 = 19

In the fourth iteration

numA = 4, numB = 5, answer = 19

So:

answer = answer + numA + numB= 19 + 4 + 5 = 28

Lastly, the value of "answer" is printed

<em>Hence, the output is 28</em>

Consider the two computers A and B with the clock cycle times 100 ps and 150 ps respectively for some program. The number of cyc
Kipish [7]

Answer:

Option d) B is 1.33 times faster than A

Given:

Clock time, t_{A} = 100 ps

t_{A} = 150 ps

No. of cycles per instructions,  n_{A} = 2.0

n_{B} = 1.0

Solution:

Let I be the no. of instructions for the program.

CPU clock cycle, f_{A} = 2.0 I

CPU clock cycle, f_{B} = 1.0 I

Now,

CPU time for each can be calculated as:

CPU time, T = CPU clock cycle\times clock time

T_{A} = f_{A}\times t_{A} = 2.0 I\times 100 = 200 I ps

T_{B} = f_{B}\times t_{B} = 1.0 I\times 100 = 150 I ps

Thus B is faster than A

Now,

\frac{Performance of A}{Performance of B} = \frac{T_{A}}{T_{B}}

\frac{Performance of A}{Performance of B} = \frac{200}{150}

Performance of B is 1.33 times that of A
