1.4.3: If-else-statement 1) What is the value of abs after the following lines of code are run? x := 2 If ( x > 0 ) abs := x Else abs := -x End-if 2 The condition ( x > 0 ) evaluates to true because the value of x is 2. The line abs := x is executed and the line abs := -x is skipped. Therefore the final value of abs is 2. 1.4.3: If-else-statement 2) What is the value of abs after the following lines of code are run? x := -2 If ( x > 0 ) abs := xElse abs := -x End-if

Set Difference A - B, the set containing those elements that are in A but not in B Set Symmetric Difference A ⊕ B: the set of elements that are a member of exactly one of A and B, but not both. An alternative definition of the symmetric difference operation is: A ⊕ B = ( A - B ) ∪ ( B - A ) Set Complement the set of all elements in U that are not elements of A. An alternative definition of A is U - A. Set Intersection A ∩ B: the resulting set that contains...

Discrete Math Final Exam Test 2024. Statement - ANSWER A statement (proposition) is a sentence that is either true or false, but not both. Negation - ANSWER A negation of a statement p is the statement "not p" or "it is not the case that p," and is denoted by ⌐p. A statement and its negation always have the opposite truth value. Conjunction - ANSWER The conjunction of two statements p and q is the statement "p and q," and is denoted by p ᴧ q. The conjunction p ᴧ q is true if b...
