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

Answer:
The answer is "increase in the power of public universities and increased appreciation for a liberal arts education". DARPA and Russia had nothing to do with this. Yes, the computer hardware improvement led to a growth, but National Science Foundation funding in 1981, and hence this is also not an option. And electrical power supply had nothing to do with this. Hence, the above answer. as the concept of the internet is based on liberal arts of education, to impart practical and intellectual skillsets, and hence to grow the social responsibility among the citizens of the whole world. Also, the power of public universities had a big role to play definitely, and this was confirmed from Pentagon as well then when the question was raised, is this due to the risk of a nuclear attack.
Many people think that the main reason was the nuclear attack threat, but that was not an issue definitely. Actually this was the time of liberalization, and the power of the public universities was increased. Hence, they got the chance to share the information of various sorts with the people, and in the process internet started expanding.
Explanation:
The answer is self explanatory.
Answer:
1. It is so important for all application builders to always check data received from unknown sources before using that data. This is because of the Security related reasons and vulnerabilities .For example the data received might contain harmful hidden viruses. Web applications are accessed by internet and these are the most vulnerable to attacks by hacker or intruders using harmful data containing malware. This can cause security breaches due to the security flaws or bugs in Web applications. So to overcome such security risks which can cause damage in the Web applications, data from unknown sources should be checked.
