Suppоse yоu аre оne of а pаir of developers creating a library of functions for a Stack class. You are responsible for writing the library’s specifications, and your partner is responsible for its implementation. An implementation skeleton for the Stack class is below. public class Stack { // wraps int and points to StackItem below it on stack class StackItem { int data; StackItem itemBelow; // contains appropriate constructor and getter methods } private int size; // number of items on the stack private StackItem top; // points to top item of stack; null if empty public Stack() { this.size = 0; this.top = null; } public Stack(StackItem si) { // traverses each StackItem starting at si, following itemBelow, until // a null itemBelow is found; creates a duplicate copy of each StackItem // and links them in the same order as they are traversed; si becomes // the top of the new Stack }} Consider the Stack class’s invariants (that is, executable expressions that evaluate to boolean values the Stack class must satisfy before and after each operation). Write down these invariant expressions as assert statements using the skeleton above for implementation details. You may need to write a helper function executed as part of these expressions. For example, if one such invariant were that the elements of the stack were sorted (which is not a correct invariant; we use it solely for the sake of giving an example of what your answer should look like), then we might write this invariant by first creating a helper function “isSorted” and then asserting its output is true: boolean isSorted() { // helper function if (this.top == null) { return true; } StackItem lastItem = this.top; StackItem thisItem = this.top.itemBelow; while (thisItem != null) { if (thisItem.data < lastItem.data) { return false; } lastItem = thisItem; thisItem = thisItem.itemBelow; } return true; } assert this.isSorted(); // invariant assertion
