Problem 6. A common practice in programming is to build adaptable code. One way to accomplish this is to allow certain operations, like a comparison, to be defined externally in order for custom behavior. Consider the following code: def comp (lhs, rhs) return (1hs % 2) -rhs) Let be the relation on the set Z defined by y if and only if comp(x, y) returns True. 6(a) Write the numbers: ,2, 3, 4, 5, 6, 7, 8 based on the ordering . That is, if a y, then r should appear before y in the list. 6(b) Explain, in English, how orders the numbers. 6(c) Prove that is a total ordering.
