Answer:
The value of the following expression is "2".
Explanation:
Here x has value 2 means x=2,and y has value 2 means y=2.
so (x+3)/(4-y)
(2+3)/(4-2)
5/2 it gives 2 because /(slash) operator gives the quotient part .The slash operator divide the left hand operand by the right hand operand.On dividing 5/2 it returns integer value i.e 2.
Data security refers to the process of protecting data from unauthorized access and data corruption throughout its lifecycle. Data security includes data encryption, tokenization, and key management practices that protect data across all applications and platforms.
Explanation:
Super Computer are expensive computer that are used to provide very quick results. Super computer are used in calculating complex mathematical calculations. Calculations such as weather forecast and Atomic energy research. Therefore Super Computer perform complex calculations rapidly.
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
