Tree Traversals A tree traversal is the process of "visiting" each node of a tree in some particular order. For a binary search tree, we can talk about an inorder traversal and a preorder traversal. For this assignment you are to implement both of these traversals in the code that was started in class. File bstree.h contains the BSTree class that was developed during class (with the addition of comments which were omitted by your instructor due to time constraints). The class contains two inorder functions, one public and one private, and two preorder functions, also one public and one private. As was the case with other functions implemented for this class, the public versions of these functions simply call the private versions passing the root node (pointer) as a parameter. The private versions carry out their actions on the subtree rooted at the given node. The code provided in bstree.h is missing the implementations for the private inorder and preorder functions. The coding part of this assignment is to implement these two functions. When completed, the test program provided should produce the following output: Values stored in the tree are: bird cat deer dog giraffe groundhog horse snake turtle The structure of the tree is as follows: dog -bird --cat ---deer -turtle --giraffe ---snake ----groundhog -----horse Copied! Written Part In addition to the coding noted above, give an analysis of all public member functions of the class, including all constructors, the destructor, and the overload of the assignment operator. For your analysis you may assume a well-balanced tree (whereas a lopsided tree might lead to a different analysis). bstree.h #pragma once // A Binary Search Tree implementation. template <typename T> class BSTree { private: // A node in the tree. Each node has pointers to its left and right nodes // as well as its parent. When a node is created, the parent and data item // must be provided. class node { public: T data; node* left; node* right; node* parent; node (const T& d, node* p) { parent = p; data = d; left = right = nullptr; } }; // Pointer to the root node. Initially this is null for an empty tree. node* root; // Copy the subtree of another BSTree object into this object. Used by // the copy constructor and assignment operator. void copy (node* p) { if (p) { // If p points to a node... insert(p->data); // Insert data item copy(p->left); // Copy the left subtree copy(p->right); // Copy the right subtree } } // Destroy a node and all nodes in both subtrees. Called by the // destructor. void destroy (node* p) { if (p) { // If p is not null... destroy(p->left); // Destroy the left subtree destroy(p->right); // Destroy the right subtree delete p; // Destroy the node } } // Helper function to determine if a data value is contained in the tree. // Takes the data value being searched and a pointer to the node in the // tree.

Sargent Corporation bought equipment on January 1, 2013. The equipment cost $180,000 and had an expected salvage value of $30,000. The life of the equipment was estimated to be 6 years. The book value of the equipment at the beginning of the third year using straight-line depreciation would be . C $180,000. $150,000. $130,000. $50,000. Solution As per the information provided, Sargent Corporation bought an equipment on Jan 1, 2013 for $180000 with 6 years life and salvage value of $30000. Therefore, depreciation expense every year as per Straight line method would be:- Equipment cost = $180000 LESS:- Salvage value = $30000 Amount on which depriciation is to be charged =$150000 Now, depreciation as per straight line method = $150000 / 6 years = $25000 every year Now, book value of Equipment at the beginning of third year is:- Equipment cost = $180000 LESS :- Depreciation for first and second year = $25000 x 2 years = $50000 Therefore, book value at begginning of third year =$130000 Hence, as per the problem \"Option C\" is correct with book value of $130000..

C++: Doubly-Linked Lists The goal of the exercise is to implement a class List of doubly- linked lists. My goal is to implement the class in a file doubly-linked.cpp. The class List implements lists using the following structures for list elements: struct Node { int val ; Node next; Node prev; }; Each Node contains a value (an integer) and two pointers: one meant to point to the next element of the list and one meant to point to the previous element in the list. The class provides the following methods that you need to implement: • A constructor and a destructor, with no arguments; • void insert(int n): insert an integer at the end of the list; • void reverse(): reverse the list; • void print(): print the list to cout in the same format as the input (i.e. integers separated by spaces); doubly-linked.h #ifndef __dll__ #define __dll__ #include using namespace std; // Basic structure to store elements of a list struct Node { int val; // contains the value Node * next; // pointer to the next element in the list Node * prev; // pointer to the previous element in the list }; // Class List class List { public: List(void); // Constructor ~List(void); // Destructor void insert(int n); // This should insert n in the list void reverse(void); // This should reverse the list void print(void); // This shoiuld print the list private: Node * first; // Pointer to the first (if any) element in the list }; #endif main.cpp #include #include \"doubly-linked.h\" using namespace std; int main(void){ List l; int n; while(cin >> n){ l.insert(n); } // Print list as read from cin l.print(); // Reverse the list and print it l.reverse(); l.print(); // Reverse again and print it l.reverse(); l.print(); return 0; } Solution #include using namespace std; /* Linked list structure */ struct list { struct list *prev; int data; struct list *next; } *node = NULL, *first = NULL, *last = NULL, *node1 = NULL, *node2 = NULL; class linkedlist { public: /* Function for create/insert node at the beginning of Linked list */ void insrt_frnt() { list *addBeg = new list; cout << \"Enter value for the node:\" << endl; cin >> addBeg->data; if(first == NULL) { addBeg->prev = NULL; addBeg->next = NULL; first = addBeg; last = addBeg; cout << \"Linked list Created!\" << endl; } else { addBeg->prev = NULL; first->prev = addBeg; addBeg->next = first; first = addBeg; cout << \"Data Inserted at the beginning of the Linked list!\" << endl; } } /* Function for create/insert node at the end of Linked list */ void insrt_end() { list *addEnd = new list; cout << \"Enter value for the node:\" << endl; cin >> addEnd->data; if(first == NULL) { addEnd->prev = NULL; addEnd->next = NULL; first = addEnd; last = addEnd; cout << \"Linked list Created!\" << endl; } else { addEnd->next = NULL; last->next = addEnd; addEnd->prev = last; last = addEnd; cout << \"Data Inserted at the end of the Linked list!\" << endl; } } /* Function for Display Linked list */ void display() { node = first; cout << \"List of data in L.

Write a program that accepts an arithmetic expression of unsigned integers in postfix notation and builds the arithmetic expression tree that represents that expression. From that tree, the corresponding fully parenthesized infix expression should be displayed and a file should be generated that contains the three address format instructions. This topic is discussed in the week 4 reading in module 2, section II-B. The main class should create the GUI shown below: Pressing the Construct Tree button should cause the tree to be constructed and using that tree, the corresponding infix expression should be displayed and the three address instruction file should be generated. The postfix expression input should not be required to have spaces between every token. Note in the above example that 9+- are not separated by spaces. The above example should produce the following output file containing the three address instructions: Add R0 5 9 Sub R1 3 R0 Mul R2 2 3 Div R3 R1 R2 Inheritance should be used to define the arithmetic expression tree. At a minimum, it should involve three classes: an abstract class for the tree nodes and two derived classes, one for operand nodes and another for operator nodes. Other classes should be included as needed to accomplish good object-oriented design. All instance data must be declared as private. You may assume that the expression is syntactically correct with regard to the order of operators and operands, but you should check for invalid tokens, such as characters that are not valid operators or operands such as 2a, which are not valid integers. If an invalid token is detected a RuntimeException should be thrown and caught by the main class and an appropriate error message should be displayed.

This assignment and the next (#5) involve design and development of a sequential non contiguous and dynamic datastructure called LinkedList. A linked list object is a container consisting of connected ListNode objects. As before, we are not going to use pre-fabricated classes from the c++ library, but construct the LinkedList ADT from scratch. The first step is construction and testing of the ListNode class. A ListNode object contains a data field and a pointer to the next ListNode object (note the recursive definition). #This assignment requires you to 1. Read the Assignment 4 Notes 2. Watch the Assignment 4 Support video 3. Implement the following methods of the ListNode class -custom constructor -setters for next pointer and data 4. Implement the insert and remove method in the main program 5. Scan the given template to find the above //TODO and implement the code needed //TODO in ListNodecpp.h file public: ListNode(T idata, ListNode<T> * newNext); public: void setNext(ListNode<T> * newNext); public: void setData(T newData); // TODO in main program void remove(ListNode<int> * &front,int value) void insert(ListNode<int> * &front,int value) # The driver is given ListNodeMain.cpp is given to you that does the following tests 1. Declares a pointer called front to point to a ListNode of datatype integer 2. Constructs four ListNodes with data 1,2,4 and adds them to form a linked list. 3. Inserts ListNode with data 3 to the list 4. Removes node 1 and adds it back to test removing and adding the first element 5. Removes node 3 to test removing a middle node 6. Removes node 4 to test removing the last node 7. Attempt to remove a non existent node 8. Remove all existing nodes to empty the list 9. Insert node 4 and then node 1 to test if insertions preserve order 10.Print the list Main.cpp #include <iostream> #include "ListNodecpp.h" // REMEMBER each ListNode has two parts : a data field // and an address field. The address is either null or points to the next node //in the chain //Requires: integer value for searching, address of front //Effects: traverses the list node chain starting from front until the end comparing search value with listnode getData. Returns the original search value if found, if not adds +1 to indicate not found //Modifies: Nothing int search(ListNode<int> * front, int value); //Requires: integer value for inserting, address of front //Effects: creates a new ListNode with value and inserts in proper position (increasing order)in the chain. If chain is empty, adds to the beginning //Modifies: front, if node is added at the beginning. //Also changes the next pointer of the previous node to point to the //newly inserted list node. the next pointer of the newly inserted pointer //points to what was the next of the previous node. //This way both previous and current links are adjusted //******** NOTE the use of & in passing pointer to front as parameter - // Why do you think this is needed ?********** void insert(ListNode<int> * &fr.
