Consider the following statements: stackType<int> stack; int x; Suppose that the input is: 14 45 34 23 10 5 -999 Show what is output by the following segment of code: stack.push(5); cin >> x; while (x != -999) { if (x % 2 == 0) { if (!stack.isFullStack()) stack.push(x); } else cout << "x = " << x << endl; cin >> x; } cout << "Stack Elements: "; while (!stack.isEmptyStack()) { cout << " " << stack.top(); stack.pop(); } cout << endl;
Consider the following stack, which can be written as [70, 10, 50, 80, 20] i.e. the "top" of the stack is the first element in the list Consider the following code (written as pseudocode): myfunction( stack1 ) stack2 = createStack() while stack1 is NOT empty value = top(stack1) pop(stack1) while stack2 is NOT empty and top(stack2) > value push(stack1, top(stack2)) pop(stack2) push(stack2, value) print(stack2) // Prints the current stack as [element_1, element_2, ..., element_n] return stack2 From the answers below, select the correct output for the first 4 print statements if myFunction is executed with: myFunction( [ 70, 10, 50, 80, 20] )

Instructions C++ a. Add the following operation to the class stackType. void reverseStack(stackType<Type> &otherStack); This operation copies the elements of a stack in reverse order onto another stack. Consider the following statements: stackType<int> stack1;stackType<int> stack2; The statement stack1.reverseStack(stack2); copies the elements of stack1 onto stack2 in reverse order. That is, the top element of stack1 is the bottom element of stack2, and so on. The old contents of stack2 are destroyed, and stack1 is unchanged. b. Write the definition of the function template to implement the operation reverseStack. Write a program to test the class stackType. myStack.h //Header file: myStack.h #ifndef H_StackType #define H_StackType #include <iostream> #include <cassert> #include "stackADT.h" using namespace std; template <class Type> class stackType: public stackADT<Type> { public: const stackType<Type>&…
Write an interactive java program for evaluating postfix expressions. The program will allow the user to enter a postfix expression from the keyboard. Assume the expression is entered correctly. Output to the screen the stack evaluation (showing the stack) after each step and final expression value. Finally, promptthe user if he/she wishes to perform another calculation or quit the program. Check case. The program must use a stack data structure. Refer to the sample output below. Sample Run:Enter a postfix expression: 4 5 2 * + Stack Contents: After push operation: 4 After push operation: 4 5 After push operation: 4 5 2 After * operation: 4 10 After + operation: 14 Final Value: 14 Enter another expression (Y/N)? y Enter an infix expression: 5 7 + 6 2 - * Stack Contents:After push operation: 5 After push operation: 5 7 After + operation: 12 After push operation: 12 6 After push operation: 12 6 2 After - operation: 12 4 After * operation: 48 Final Value: 48 Enter another expression…
Suppose you have a stack with a maximum size of 1000 elements and you want to perform the following operations: Push 500 elements onto the stack. Pop 200 elements from the stack. Push 800 elements onto the stack. Pop all remaining elements from the stack. What is the final size of the stack after performing all these operations?
4. a) Using the stack diagram, convert the following infix expression to a postfix expression. A + B / C * (D – E) b) Referring to question 4 (a), give the value of postfix expression by using the stack concept if provided: A=13, B=20, C=4, D=30, E=25
A data structure known as a drop-out stack functions exactly like a stack, with the exception that if the stack size is n, the first element is lost when the n + 1 element is pushed. Apply an array to a drop-out stack. (Hint: It would make sense to implement a circular array.)

Question#3.Write a Python program to reverse a stack using recursion. Problem Solution Hints: 1. Create a class Stack with instance variable items initialized to an empty list. 2. Define methods push, pop, is_empty and display inside the class Stack. 3. The method push appends data to items. 4. The method pop pops the first element in items. 5. The method is_empty returns True only if items is empty. 6. The method display prints the elements of the stack from top to bottom. 7. Define function insert_at_bottom which takes a stack and a data item as arguments. 8. The function insert_at_bottom adds the data item to the bottom of the stack using recursion. 9. Define function reverse_stack which takes a stack as argument. 10. The function reverse_stack reverses the stack using recursion. 11. Create an instance of Stack, push data to it and reverse the stack.
A data structure known as a drop-out stack functions exactly like a stack, with the exception that if the stack size is n, the first element is lost when the n + 1 element is pushed. Use an array to implement a drop-out stack. (Hint: It would make sense to implement a circular array.)
Please explain the difference between Stack and Heap. Including data on the frame pointer, the stack pointer, and other relevant variables.
