Chapter 25.6, Problem 25.6.3CP

Explanation of Solution

“java.util.PriorityQueue” class:

This is an unbounded priority queue based on a priority heap. It does not allow null elements. In priority queue the elements are ordered according to the ordinary order.

Given statement in Listing 25.9:

  • In the given statement initially create the single node tree and added to the heap.
  • In every iteration, the “while” condition set the two smallest weight which are removed from the heap and are gathered to form a big tree, then the new tree is added to the heap...

Students might find it difficult to implement stack using array or linked list or both. For example, in array based implementation, students have to check for stack overflow and underflow exceptions. Also, in case of linked list based implementation, only stack underflow condition needs to be checked. Solutions: Students have to create class for stack related exceptions. Two different classes can be declared, one for overflow and one for underflow. Both classes need to extend the Exception class of Java. Put stack’s push and pop methods inside a try-catch block and handle the exceptions. It can get difficult or confusing to check all conditions of parenthesis matching. Because, when a closing parenthesis/curly brace/bracket is encountered one needs to make sure the correct type of opening parenthesis/curly brace/bracket are popped from the stack   Solutions: Students need to write if-else if checking for each type of parenthesis/curly brace/bracket separately when an opening…
Write a Reverse Polish Notation (RPN) calculator in Java. Write a Stack class for doubles: constructor and push, pop, empty, peek functions. Use an array implementation for the stack (or a linked list if you did this before class on 3/5). If you want, you can limit the stack size to ten (HP only had three on their first attempt!), but in that case you should make your push do nothing if the stack is full. Most modern stack implementations have no arbitrary size limit. The pop and peek methods should throw an exception if they are called on an empty stack (see code for this below). Write a RPN class: constructor (takes a String expression, e.g. "3 4 5 + *") and an evaluate method which returns a double ("3 4 5 + *" would evaluate to (4+5)*3=27). Write a RPNCalculator class: main method with whatever accouterments you see fit. Allow the user to type in an expression, then evaluate it and repeat until they say quit.
This is in c++ Given the MileageTrackerNode class, complete main() to insert nodes into a linked list (using the InsertAfter() function). The first user-input value is the number of nodes in the linked list. Use the PrintNodeData() function to print the entire linked list. Don't print the dummy head node. Example input : 3 2.2 7/2/18 3.2 7/7/18 4.5 7/16/18   output:  2.2, 7/2/18 3.2, 7/7/18 4.5, 7/16/18   main.cpp: #include "MileageTrackerNode.h"#include <string>#include <iostream>using namespace std; int main (int argc, char* argv[]) {// References for MileageTrackerNode objectsMileageTrackerNode* headNode;MileageTrackerNode* currNode;MileageTrackerNode* lastNode; double miles;string date;int i; // Front of nodes listheadNode = new MileageTrackerNode();lastNode = headNode; // TODO: Read in the number of nodes // TODO: For the read in number of nodes, read// in data and insert into the linked list // TODO: Call the PrintNodeData() method// to print the entire linked list //…
