Lab 4: 30 pts The main new components in this lab are discussed in Chapter 3's section on singly linked lists and were reviewed in class. IMPORTANT:  This lab builds on Lab 3, so if you didn't do it, then complete Lab 3 as a part of this lab, but see next comment on GRADING to understand how that works. GRADING:  I won't be deducting points if you didn't do parts of the Lab 3 piece correctly.   I will only be grading your implementation of the Linked List and how you use it and the player move count. SUMMARY Add to Lab 3 by tracking the player's moves in a linked list.  Then, before printing out the maze at the end, cycle through all the nodes of the linked list and change the cell value of each grid spot where the user has been to a number like 8 or 5 or 3 or any integer other than 0 or 1.  This way the grid print out at the end will show the player's path. Secondly, track the number of moves the player makes and print that out at the end as well. This lab will involve the following new features: Singly Linked List DETAILS There won't be as much detail on the singly linked list since we went over an implementation in class. Classes and Adjustments to Lab 3. Node - This is a new class that needs to be added to Lab 3. Instance variables: xPosition - int type. yPosition - int type. nextNode - Node type. LinkedList - This class will hold the linked list. Instance variables: headNode - Node type. Methods: addHeadNode Takes in two parameters, x and y, which are integer types. Returns nothing. With the x and y params, it creates a new node object and sets the nextNode on the new node object to the existing headNode object. It then assigns this new node object to the headNode variable. removeHeadNode Takes in no parameters. This is tricky so you need to carefully think through how to do this, but the following is what it needs to accomplish: It needs to change the current head node to the node that is in the head node's nextNode variable; and it needs to return that previous head node to the method caller. Essentially, you're taking the head node out of the linked list and returning it and setting the next node in line as the new head node. Updating run method in GameGrid class. You need to instantiate a LinkedList instance. In the while loop, use the iUserRow and iUserCol values to call the addHeadNode method on the LinkedList instance to add a node for every user move. Create second while loop:  AFTER the existing while loop exits but BEFORE the grid print out. This loop will run until all LinkedList nodes have been processed. In the loop, call the removeHeadNode method on the LinkedList instance and use the returned node's xPosition and yPosition to update the grid at that position with any number you choose besides 0 and 1. You can also use this loop to count the number of player moves. Print out the total number of player moves at the end when printing the grid. 

This week you will learn about the programming software Raptor. Set up and explore the logic development tool.Download and install Raptor - Be sure to use the Raptor download and not an advertisement (Use the link here in color) | Resource Explore Raptor Syntax | Resource p.1-p.2 Explore Raptor Variables | Resource p.3 - p.5Did you experience any issues setting up the program? After installation, what did learn through exploring Raptor? Did you understand how to navigate the syntax and variables within the software? Step 2Next, learn how to express program data logically using variables and literal constants. Express data logically using variables, constants and assignments by watching the following video:Play Video. Take notes on the following: -Type of Statements (declaration & assignment) -Primitive Data types -Variable and literal constants (def., declaration & naming rules)Task to be delivered in week 3 before Week 3 deadline on 06/14/2020:Launch the Raptor tool from the previous steps.   Create a short program that displays your name.   Take a screen shot of the main screen and paste in a word document.    Submit a summary of your experience and any observations, difficulties, and/or successes in Word Format in 1-2 pages along with your screenshot for creating a short program that displays your name .
