Assignment:
Test the binary relations on S for reflexivity, symmetry ,antisymmetry, and transitivity
A) S = Q
X p Y <-> ABS(X) <= ABS(Y)
B) S = Z
X p Y <-> x -y is an integral multiple of 3
C) S = N
X P Y <-> X is odd
D) S = Set of all squares in the place
S1 p S2 <-> length of side of S1 = length of side S2
E) S = set of finite-length strings of characters
X p Y <-> number of characters in x = number of characters in y
Provide complete and step by step solution for the question and show calculations and use formulas.
