The Stаck clаss must suppоrt the fоllоwing functions. void push(int x), which puts the аrgument x on the top of the Stack int pop(), which removes the int at the top of the Stack and returns it For each of these functions, write reasonable and appropriate predicates (that is, executable expressions that evaluate to boolean values) for the precondition and postcondition. You may also need to write code other than the pre- or postconditions to obtain valid boolean expressions. Your answers should have the form of the following. public void push(int x) { assert /* TODO: fill in precondition here */; /* TODO: add any code to be run after the precondition */ /* IMPLEMENTATION - LEAVE THIS LINE HERE */ /* TODO: add any code to be run before the postcondition */ assert /* TODO: fill in postcondition here */; } public int pop() { assert /* TODO: fill in precondition here */; /* TODO: add any code to be run after the precondition */ /* IMPLEMENTATION - LEAVE THIS LINE HERE */ /* TODO: add any code to be run before the postcondition */ assert /* TODO: fill in postcondition here */; return x; // assume x is an int defined in the implementation } Additional notes: If you believe there need not be a pre- or postcondition for a function, you can use the statement assert true to denote that fact. Feel free to define and use any helper functions as needed. Make sure your code does not have any side-effects if assert statements were turned off. For help writing postconditions, you can call new Stack(this.top) before the implementation line to allow you to duplicate the state of the Stack before the function’s operation. You may assume any invariants you give for the previous question are automatically checked before and after each method, so you don’t need to include them in your pre- and postconditions.
