Question

1). Create a stack data structure (MUStack) given the sample class with methods below.

public class MUStack<E> {

private class Node<E> (

private E data;

Node<E> next;

public Node (E data) {

this.data = data;

this.next=null;

}

private Node<E> top;

private int count; //number of elements in the stack

public MUStack() {

}

public E pop(){

{

public void push (E data) {

}

public E peek() {

}

public int size () {

}

2). Write a a program that implements the following algorithm to evaluate postfix that will use the (MUStack)

Evaluation of postfix string

Using StringTokenizer or split
While (there are more tokens)
Get next token
If this token is numeric push it on the stack
If it is an operator (+. -/, *)
Pop the top two elements from the stack
Perform the operation indicated by the operator
Push the result on the stack
End while
The answer will on the top of the stack

The program should:

Ask the user to enter a space delimited postfix string or Quit
If the User chooses the Quit option, terminate the program.
If the user selects the other option,

Ask the user to enter a space delimited postfix string
Evaluate the postfix using the MUStack and the algorithm above
Print the calculated value
Go back to step 1
