The question keeps getting answered wrong please read the instructions before answering. This is my fifth time asking,it does not seem right that I have to waste all of my questions because it keeps getting answered wrong.

I need a working jsfiddle. The html and javascript must be separate

.

Assignment

Implement a Stack in Javascript (you will turn in a link to your program in JSFiddle). Do not use an array as the stack or in the implementation of the stack. Repeat - You MUST implement the Stack (start with your linked list) without the use of an array..

You will build a Stack Computer from your stack. When a number is entered it goes onto the top of the stack. When an operation is entered, the previous 2 numbers are operated on by the operation and the result is pushed onto the top of the stack. This is how an RPN calculator.

For example

2 [enter] 2

5 [enter] 5 2

* [enter] * 5 2 -> collapses to 10

would leave at 10 at the top of the stack.

The program should use a simple input box, either a text field or prompt and display the contents of the Stack.

Contents of Stack:

Information

Building A Stack is relatively easy if you have built a List. A Stack is nothing more complex with 2 extra functions added Push(_value) and Pop(). The Push function obviously needs an argument _value. The Pop function should always return the element on the top of the stack and at the same time removing it from the top of the stack.

Here is what I have but the calculations do not seem to work correctly.4+5 should not = 54

L1 = [];

Q1 = [];

var all_count = 1;

var setter = 0;

var Index = 0;

var count = 1;

var html = " ";

function List_one(){

var limit = prompt("please enter a number you would like to fill L1 to.");

for(i = 2; i <= limit; i++)

{

L1[setter] = i;

setter++;

}

while(all_count <= L1.length)

{

var value = L1[0];

Q1[Index] = value;

Index++;

L1.shift();

for(i = 0; i <= L1.length; i++){

if(L1[i] % value == 0)

{

L1.splice(i, 1);

}

}

html += "

" + "L1= " + L1 + " Q1 = " + Q1 + "

";

document.getElementById("demo").innerHTML = html;

}

}

function Stack() {

var items = [];

this.push = function(element){

items.push(element);

};

this.pop = function(){

return items.pop();

};

this.peek = function(){

return items[items.length-1];

};

this.isEmpty = function(){

return items.length == 0;

};

this.size = function(){

return items.length;

};

this.clear = function(){

items = [];

};

this.print = function(){

alert("Stack Elements are:"+items.toString());

};

}

//Decalre stack object

var stack = new Stack();

while(1)

{

var element = prompt("Enter stack element,(q or Q to exit)", "");

if(element == 'q' || element =='Q')

{

break;

}

else

{

if(element=='*'

|| element=='+' || element=='-' || element=='/')

{

//Check if stack is empty

if(stack.isEmpty() || stack.size<2 )

{

alert("Invalid Operation, Stack is empty or size is less than 2");

}

else

{

var op1 = stack.pop();

var op2 = stack.pop();

if(element=='*')

{

var res = op1 * op2;

}

else if(element=='+')

{

var res = op1 + op2;

}

else if(element=='-')

{

var res = op1 - op2;
