Answer:
The correct answer is option A
Explanation:
Solution
Recall that:
From the question stated,the following segments of code that should be used in replacing the /* missing code */ so that the value 20 will be printed is given below:
Android a = new Android(x);
a.setServoCount(y);
System.out.println(a.getServoCount());
The right option to be used here is A.
Answer:
xyz = 25
result = square(xyz)
print(result)
The above code assigns the value 25 to variable xyz as 5*5=25. Then next statement is a function call to square() function passing xyz to this function in order to compute the square of 25. The output is:
625
Explanation:
The above code can also be written as:
xyz = 5*5
result = square(xyz)
print(result)
The difference is that xyz is assiged 5*5 which is equal to 25 so the output produced will be the same i.e. 625.
The result variable is used to store the value of square of 25 after the square() method computes and returns the square of 25. So print(result) prints the resultant value stored in the result variable i.e. 625
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 hexadecimal equivalent of the encrypted A is C2
Explanation:
Given
Encrypted binary digit of A = 11000010
Required
Hexadecimal equivalent of the encrypted binary digit.
We start by grouping 11000010 in 4 bits
This is as follows;
1100 0010
The we write down the hexadecimal equivalent of each groupings
1100 is equivalent to 12 in hexadecimal
So, 1100 = 12 = C
0010 is represented by 2 in hexadecimal
So, 0010 = 2
Writing this result together; this gives
1100 0010 = C2
Going through the conversion process;
A is first converted to binary digits by shifting a point to the left
A => 11000010
11000010 is then converted to hexadecimal
11000010 = C2
Conclusively, the hexadecimal equivalent of the encrypted A is C2
