Chapter 29.6, Problem 29.6.1CP
Program Plan Intro
Weighted Graph:
A graph is termed as weighted graph if each edge of the graph is assigned a weight. The weighted edges stored in the weighted graphs can be stored in adjacency lists.
Weighted edges can be represented using a two-dimensional array. An weighted edge can be represented as “WeightedEdge(u,v,w)”, where “u” and “v” are edges and “w” represents the weight between them.
Example of storing edge in a weighted graph:
Object[][] edges =
{ new Integer(0), new Integer(1), new SomeTypeForWeight(8) };
Nine Tails
In Nine Tails Program, nine coins are placed in a 3*3 matrix, where some coins are face up and others face down, in which a legal move is to take any coin that is face up and reverse it together with the coins adjacent to it. One needs to find the minimum numbers of moves that leads to all coins being face down.
The Nine Tails program can be reduced to the shortest path problem.
The tree data field in NineTailModel is defined protected:
protected UnweightedGraph<Integer>.SearchTree tree;

There seems to be a lot of code needed to maintain the node count field in Node. Is it actually required? Why not use a single instance variable to build the size() client function that holds the total number of nodes in the tree?
There seems to be a lot of code needed to maintain the node count field in Node. Is it truly required? Why not use a single instance variable to build the size() client function that holds the total number of nodes in the tree?
The node count feature in Node appears to need a significant amount of code. Is it really necessary? Why not construct the size() client function, which stores the entire number of nodes in the tree, using a single instance variable?

Our first class is Node which we can make a new node with a given element. Its constructor also includes previous node reference prev and next node reference next. We have another class called DoublyLinkedList which has start_node attribute in its constructor as well as the methods such as: 1. insert_to_empty_list() 2. insert_to_end() 3. insert_at_index() Hints: Make a node object for the new element. Check if the index >= 0.If index is 0, make new node as head; else, make a temp node and iterate to the node previous to the index.If the previous node is not null, adjust the prev and next references.

- True or False: Does the DST tree (digital search tree) require the key type to implement the Java Comparable?arrow_forwardWhen I try to run a Java code in the NetBeans IDE, it says "Erroneous tree type scanner" and doesn't run. How to fix?arrow_forwardBuild a Node class. It is should have attributes for the data it stores as well as its left and right children. As a bonus, try including the Comparable module and make nodes compare using their data attribute. Build a Tree class that accepts an array when initialized. The Tree class should have a root attribute that uses the return value of #build_tree which you'll write next. Write a #build_tree method that takes an array of data (e.g. [1, 7, 4, 23, 8, 9, 4, 3, 5, 7, 9, 67, 6345, 324]) and turns it into a balanced binary tree full of Node objects appropriately placed (don't forget to sort and remove duplicates!). The #build_tree method should return the level-1 root node. Write an #insert and #delete method which accepts a value to insert/delete. Compile and submit your source code and screenshots of the application executing the application and the results based in python. Your paper should be 2-3 pages in length (not including title and references pages)arrow_forward

The current issue is that it does not accept the Object that is supplied to it.arrow_forwardEach of the iterators must implement the java.util.Iterator interface by providing the two public methods hasNext () and next(). The Iterator interface also lists two additional methods, remove () and forEachRemaining (). These are marked as default, so the interface itself does not require implementation. Of these methods, this assignment only requires you to implement the remove () method of the linked list iterator. 1 ArrayList iterator This is an external iterator, meaning it is a public class named ICS211ArrayListIterator, and and the code is not part of the ArrayList class. Your ICS211ArrayListIterator class should have a constructor ICS211ArrayListIterator(java.util.ArrayList gives access to all the elements of the array list. This array must be saved as the value of a class variable of the iterator. data). The constructor must call one of the two toArray methods of ArrayList to obtain an array that Other than this single call to java.util.ArrayList.toArray in the constructor,…arrow_forward
