[PYTHON]

these are the inputs and outputs that have to match exactly

I've attempted the following code. Function names can not be changed and cannot change most of the script. However, if there needs to be adjustments to the code, it can be added additionally but nothing can be delted. #Write your code here are the functions that needs to be focused.

I cannot get the right printStack function. Am I on the right track?

CMPSC-122: Intermediate Programming Spring 2018 Lab #10 Due Date: 03/30/2018, 11:59PM Instructions: - The work in this lab must be completed alone - If you need guidance, attend to your recitation class. - Read the "Submitting assignments to Vocareum" file for instructions on how to submit this lab Do not change the function names or given code on your script The file name must be LAB10.py (incorrect name files will get a 0 score) - -You are responsible for testing your code. Use python - LAB18. py in your terminal (or command prompt) to provide input to your functions. Test with as many data as you feel comfortable Each function must return the output (Do not use print in your final submission) Do not include test code outside any function in the upload. Reoe all your testing code before uploading your file. If you are using inputto insert values in your functions and print to see the values, remove them - Exercise 1 [10 pts NOTE: There is no partial credit for methods that do notworkproperly. You must ensure the entire code works after the addition of new methods. In class, we discussed the abstract data type Stack. A stack is a collection of items where items are added to and removed from the top (LIFO). Implement the stack data structure with the following operations Stacko creates a new stack that is empty. It needs no parameters and returns nothing push item) adds a new Node with value-item to the top of the stack. It needs the item and returns nothing. [2 pts] pop removes the top Node from the stack. It needs no parameters and returns the value of the Node removed from the stack. Modifies the stack. [2 pts] peek0 returns the value of the top Node from the stack but does not remove it. It needs no parameters. The stack is not modified. [2 pts] isEmpty tests to see whether the stack is empty. It needs no parameters and returns a boolean value. [2 pts] size0 returns the number of items on the stack. It needs no parameters and returns an integer [2 pts EXAMPLE >>>stack-Stack () >>>stack.push (2) >>>stack.push (4) >>>stack.push (6)
