Now we must prove that h is injective and bijective. Starting
with injectivity, let x1, x2 ∈

Create the abstract data type IntSet used to implement a mathematical set of non-negative integers (includes zero). Each object of class IntSet can keep track of whether integers are in the set or not. Implement as follows. A set is to be represented internally as a bool array containing true and false. For example, if you call the array set, then set[num] is true if the integer num is in the set, false if num is not in the set....
