Answer:
The Python code with the function is given below. Testing and output gives the results of certain chosen parameters for the program
Explanation:
def first_last(seq):
if(len(seq) == 0):
return ()
elif(len(seq) == 1):
return (seq[0],)
else:
return (seq[0], seq[len(seq)-1])
#Testing
print(first_last([]))
print(first_last([1]))
print(first_last([1,2,3,4,5]))
# Output
( )
( 1 , )
( 1 , 5 )
Answer:
=b2 b3-b4 or something close to that, I hope this helps ^^
Explanation:
The line code will create array is G = array('f',[2.5, 3, 7.4])
<h3>What is meant by array ?</h3>
As opposed to defining distinct variables for each value, arrays are used to hold numerous values in a single variable. Set the data type (such as int) and the array name, followed by square brackets [, to construct an array.
An array is a collection of elements with the same type that are kept in nearby memory locations and may each be separately referred to using an index to a special identifier. There is no need to declare five distinct variables when declaring an array of five int values (each with its own identifier).
In the C programming language, arrays are a derived data type that may contain primitive data types like int, char, double, float, etc.

Answer:
a) Speedup gain is 1.428 times.
b) Speedup gain is 1.81 times.
Explanation:
in order to calculate the speedup again of an application that has a 60 percent parallel component using Anklahls Law is speedup which state that:
Where S is the portion of the application that must be performed serially, and N is the number of processing cores.
(a) For N = 2 processing cores, and a 60%, then S = 40% or 0.4
Thus, the speedup is:
Speedup gain is 1.428 times.
(b) For N = 4 processing cores and a 60%, then S = 40% or 0.4
Thus, the speedup is:
Speedup gain is 1.81 times.
