Answer:
C. Byte pair encoding is an example of a lossless transformation because an encoded string can be restored to its original version.
Explanation:
Byte pair encoding is a form of encoding in which the most common pairs of consecutive bytes of data are replaced by a single byte which does not occur within the set of data.
For example, if we has a string ZZaaAb, it can be encoded if the pairs of string ZZ are replaced by X and the second pair by Y. So, our data now becomes XYAb.
To get our original data, that is decode it, we just replace the data with the keys X = ZZ and Y = aa thus allowing our original data to be restored.
Since our original string is restored without loss of data, it implies that <u>byte pair encoding is an example of a lossless transformation because an encoded string can be restored to its original version.</u>
Answer:
In Python:
def gcd(m,n):
if n == 0:
return m
elif m == 0:
return n
else:
return gcd(n,m%n)
Explanation:
This defines the function
def gcd(m,n):
If n is 0, return m
<em> if n == 0:
</em>
<em> return m
</em>
If m is 0, return n
<em> elif m == 0:
</em>
<em> return n
</em>
If otherwise, calculate the gcd recursively
<em> else:
</em>
<em> return gcd(n,m%n)</em>
<em />
<em>To call the function to calculate the gcd of say 15 and 5 from main, use:</em>
<em>gcd(15,5)</em>
Answer:
processing
Explanation:
The flow chart is a diagram that shows the activity of the program, peoples or things.
Flowchart symbol and meaning in the options:
1. Processing: it is a rectangular shape block which is used for variable declaration or assignment.
2. I/0: it is a parallelogram in shape which is used for input or output.
3. Parallelogram: it is used for input or output.
4. diamond: it is used for decisions or conditions.
Therefore, the correct option is a. Processing is the one that is used for the assignment statement.
