Algorithms & Programming Fundamentals
What combination of boolean operators can replace * such that returns false only when a single variable among is true?
((X && Y) && Z)
((X ^^ Y) ^ Z)
What truth value does !(X == Y)
return if X and Y have identical boolean values?
Depends On Whether X And Y Are True Or False
The Opposite Of "X And Y"
FALSE
TRUE
What is the result of the Boolean expression (true || false) && !(false || false)
?
True
False
Null
Undefined
In a conditional statement, which replacement for '???' would make the code segment below always execute its body?
python
if (???):
# Code body executes here
Null or any non-boolean value.
True or any value that evaluates to True.
An uninitialized variable.
False or any value that evaluates to False.
Which Boolean expression correctly determines if a number 'n' is odd?
In evaluating two search algorithms for efficiency where one algorithm uses sequential search and another uses binary search on sorted data sets, what will most significantly impact their performance difference?
The presence of duplicate values within the data set
The range of values within the data set
Size of the data set
The initial order of elements before sorting
Select the correct outcome when evaluating (!(A && B) && (A || B)) given that A is false and B is true.
The result cannot be determined without further information.
True
The expression causes an error.
False

What is an example of applying abstraction when dealing with boolean logic?
Differentiating user roles with unique authentication codes.
