Although it's too early in the year to know what the best one is and there are many, in 2015 the most powerful GPUs were the EVGA GeForce Titan X, the Zotac GeForce GTX 980Ti and the <span>Gigabyte Radeon R9 Fury X.</span>

Answer:
Option 3 is the correct answer.
Explanation:
- In c, c++ or Java programming language, The for loop takes three parameters in which first is an initialization, second is condition check and the third is an increment. None of the other loop (except for loop) takes three parameters. The other loop takes only one parameter and that is the condition check.
- So when a user knows about the times of iteration then it is a good choice to use the for loop but when the person does not know about the times of iteration if the loop. It means the iteration of the loop is based on the condition then it is a good choice to chose while or Do-while loop.
- The above question wants to ask which loop for a user can best if he familiar with the iteration of the loop then the answer is for loop which is started from option 3. Hence Option 3 is the correct answer while the other is not because--
- Option 1 states about the do-while loop which takes condition only.
- Option 2 states about the while loop which also takes condition only.
- Option 4 states about the infinite loop which is not any loop.
- Option 5 states about none of these which is not correct because option 3 is the correct answer.
Answer:
def sum_1k(M):
s = 0
for k in range(1, M+1):
s = s + 1.0/k
return s
def test_sum_1k():
expected_value = 1.0+1.0/2+1.0/3
computed_value = sum_1k(3)
if expected_value == computed_value:
print("Test is successful")
else:
print("Test is NOT successful")
test_sum_1k()
Explanation:
It seems the hidden part is a summation (sigma) notation that goes from 1 to M with 1/k.
- Inside the <em>sum_1k(M)</em>, iterate from 1 to M and calculate-return the sum of the expression.
- Inside the <em>test_sum_1k(),</em> calculate the <em>expected_value,</em> refers to the value that is calculated by hand and <em>computed_value,</em> refers to the value that is the result of the <em>sum_1k(3). </em>Then, compare the values and print the appropriate message
- Call the <em>test_sum_1k()</em> to see the result
