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 have asked these similar questions
What is the best way to implement a stack or a queue so that it can hold an arbitrary number of elements? Select one: a. Using an array, and throwing an exception when the stack or queue is full. b. By creating a bigger array when the stack or queue is full, and copying the elements from the original array. c. Using linked lists to store the collection of elements.
Could you help explain the difference between the restricted version of
the stack and the unbounded version of the stack? Thank you for your
time.
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…

- Answer the given question with a proper explanation and step-by-step solution. Hello team, Need some help with problems below using the langauge JAVA. I need to modify the CalcParser class provided below. I need this to produce a string containing commands to evaluate the expression on a stack machine. For example, if you give the command java CalcParser 1+2*3, the output should be a sequence of stack commands such as this: push 1.0 push 2.0 push 3.0 multiply add 7.0 For the command java CalcParser (1+2)*3, on the other hand, it should print a sequence like this: push 1.0 push 2.0 add push 3.0 multiply 9.0 CODE:public class CalcParser { private CalcLexer lexer; private String errorMessage = null; private double value; public CalcParser(String s) { lexer = new CalcLexer(s);errorMessage = lexer.getErrorMessage();if (errorMessage != null) return; value = parseExpression();if (errorMessage != null) return; match(CalcLexer.EOLN_TOKEN);if (errorMessage != null) return; } public String…arrow_forwardMy last question was not answered so I am trying again. Please solve this problem in Java. Please a create Java class that does the Pop() operation on a stack as described in the image below. The class will need to read the integers from the text file and Text file(Stack_Ints.txt): 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 Sample Output: Print: stack elements print: Popped element print: updated stack elementsarrow_forwardHere is a PDA that is nearly finished. It is designed to recognize the language { a"b²n |n > 0 }. To finish it, two more triples are needed at the location marked by the question mark. What are they? Write each triple without using any spaces. If you need a lambda or empty stack symbol write exactly the word lambda or emptystack (eg, lambda,emptystack,emptystack or b,emptystack,bemptystack). Triple 1: (write the shorter of the two triples here) Triple 2: (write the longer of the two triples here)arrow_forward
- a. Write a class called hyprid that uses linked lists to represent a queue and stack. As you can recall that the only difference in between the stack and the queue is that the stack uses the addHead method to push items and the queue uses the addTail method to insert items. The class should be implemented using LinkedLists. The class should contain the following methods: a. boolean empty() to check if the underlying list is empty b. void push(int item) to add the item using addFirst c. void insert (int item) to add the item using addLast d. int remove() to remove an item from the beginning of the list e. int pop() the same as above but with name changedarrow_forwardIt is given to you that the ADTStack is an interface that defines Stack operations and StackUsingArrays class implements this interface. What will be the output of the following java code segment?arrow_forwardCould you help explain the difference between the restricted version of the stack and the unbounded version of the stack? Thank you for your time.arrow_forward
- In C++, Write a stack class. The stack class must include at least “push”, “pop”, “top”, “isEmpty”, “isFull” methods. You can implement any additional methods, as they needed. Write your class in stack.h and stack.cpp. The part 1 does not needed to be tested.arrow_forwardPlease solve this problem in Java. It should read the elements of the stack as integers from a text file. n = 18 (number of elements/integers)arrow_forwardCan you describe the difference between the limited and unbounded stack versions?arrow_forward
- What happens if the base condition is not defined in recursion ? a. Stack underflow b. Stack Overflow c. None of these d. Both a and barrow_forwardI already asked this question once, but I receivied it in C++ form and not Java. I do my Java programming in Apache NetBeans IDE 12.2. The question is below, but please let it be Java coding: Create a two-dimensional array of type double to contain the three different SD Marks (JD521, PRG521, and IP521) for six different students. A single array of type String must be used to store the student names (Maxwell, Carl, Gerhard, Paul, James, and Cena). Allow a user to enter in a number, ranging from 1 to 6, which will represent the student position in the table MCSD max and present the marks for each respecting module. The program can only stop when the user enter a number greater than 6. Printout the student name including the JD521, PRG521, and IP521 max, the total of marks and the average of all marks. Use a condition statement to decide that the student has passed or not (Pass rate is 70). Thank you.arrow_forwardImplement a simple stack in java using the scenario below. A company wishes to keep track of the order in which it employed staff. Users can enter either "f" to fire, "h" to hire or "e" to end the program. When a member of staff is employed, their employee number is added to the top of a stack when someone has to be made redundant, the last person to join the company is removed from the top of the stack.
