For each of the properties reflexive, symmetric, antisymmetric, and transitive, carry out the following.

Assume that R and S are nonempty relations on a set A that both have the property. For each of R complement, R∪S, R∩S, and R−1, determine whether the new relation

  1. must also have that property;
  2. might have that property, but might not; or
  3. cannot have that property.
  4. A ny time you answer Statement i or Statement iii, outline a proof. Any time you answer Statement ii, provide two examples: one where the new relation has the property, and onewhere the new relation does not.

Let R be a relation on a set that is reflexive and symmetric but not transitive? Let R(x) = {y : x R y}. [Note that R(x) is the same as x / R except that R is not an equivalence relation in this case.] Does the set A = {R(x) : x ∈ A} always/sometimes/never form a partition of A? Prove that your answer is correct. Do not prove by examples.

A JAVA program that will read a boolean matrix corresponding to a relation R and output whether R is Reflexive, Symmetric, Anti-Symmetric and/or Transitive.
A JAVA program that will read a boolean matrix corresponding to a relation R and output whether R is Reflexive, Symmetric, Anti-Symmetric and/or Transitive. Input to the program will be the size n of an n x n boolean matrix followed by the matrix elements. Document your program nicely.NOTE: The program must output a reason in the case that an input relation fails to have a certain property.

Write an array method to carry out each of the following tasks for an array of integers. Note: you can think of each as a separate problem independent of the others. a) Swap the first and last elements in the array. b) Shi< all elements by one to the right and move the last element into the first posi>on. For example, 1 4 9 16 25 would be transformed into 25 1 4 9 16. c) Replace all even elements...
