What value is printed as a result of executing this algorithm?
Question 3
Q20. Suppose a computer program has been initialized such that the following sets have been stored for use in any algorithm:
A = {1, 2, 3, ..., 43}
B = {-7, -6, -5, ..., 21}
Consider the following algorithm, which represents one part of the whole computer program (comments may occur after the # symbol on any line and are not used in computations):
#Part 1: computes A - B and its cardinality
AminusB = set()
for element in A: # this line runs through every element in A
if not(element in B): #A - B is the set of elements that are in A and are not in B
AminusB.add(element) # Add to AminusB every element in A if the element is also not in B
n = len(AminusB) #len() returns the number of elements in the array
print(n)
