The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.
using java code Problem: Suppose we want to write a program for the class BinaryTree that counts the number of times an object occurs in the tree. We need to use a method with the following header, public int count (O anObject) 1. Name your class objectCounter 2. Define main method, test the program 3. Write a method using one of the iterators of the binary tree. 4. Write another method using a private recursive method of the same name NB: Can you add main method to test the code please for 2. Define main method, test the program
Computer Science create a method +addToList(o:E):void that adds the object (o) to the ArrayList referenced by the instance variable list. create a method +removeFromBackOfList():E that removes the object at the back of the ArrayList and returns it.
write a java method : Write a recursive private method called countDegree to be included in class BinaryTree as discussed in the lectures. If a node is having two child nodes, then its degree is two, if it is having one child node, its degree is one and leaf nodes have degree 0. The method counts and returns the total degree of all the nodes in the binary tree. Example: If a binary tree is having 9 nodes such that 3 nodes, each have 2 child nodes, 2 nodes each have only one child and there are 4 leaf nodes. So, the total degree of the binary tree = 3x2 + 2x1 + 0 = 8. This method is called from a public method countDegreeBT, given as follows: public int countDegreeBT() { return countDegree(root); } Method heading: private int countDegree(Node<E> node)
Given a list of integers, you want to know whether it is possible to divide the integers into two sets, so that the sum of one set is odd, and the sum of the other set is a multiple of 10. Every integer must be in one set or the other. You can write a recursive helper method that takes any number of arguments and then call it inside the method, but you cannot use any loops. Test cases: oddAndTen([5, 5, 3]) true oddAndTen ([5, 5, 4]) oddAndTen ([5, 5, 4, 1]) false true
A readinglist is a doubly linked list in which each element of the list is a book. So, you must make sure that Books are linked with the previous prev and next element. A readinglist is unsorted by default or sorted (according to title) in different context. Please pay attention to the task description below. Refer to the relevance classes for more detail information. Implement the add_book_sorted method of the ReadingList class. Assume the readinglist is sorted by title, the add_book_sorted method takes an argument new_book (a book object), it adds the new_book to the readinglist such that the readinglist remain sorted by title. For example, if the readinglist contain the following 3 books: Title: Artificial Intelligence Applications Author: Cassie Ng Published Year: 2000 Title: Python 3 Author: Jack Chan Published Year: 2016 Title: Zoo Author: Cassie Chun Published Year: 2000 If we add another book (titled "Chinese History"; author "Qin Yuan"; and published year 1989) to the…
Create a nested class called DoubleNode that allows you to create doubly-linked lists with each node containing a reference to the item before it and the item after it (or null if neither of those items exist). Then implement static methods for the following operations: insert before a given node, insert after a given node, remove a given node, remove from a given node, insert at the beginning, insert at the end, remove from a given node, and remove a given node.
10. Given the definition of a binary tree Node, write a method that returns the height ofa given node.Class TreeNode {Int value;TreeNode left;TreeNode right;}Static int height (TreeNode position) { }** Use only the definition of a TreeNode, don’t suppose we have other built-inmethods.
Hashing Create a method hashSetExe to use Java HashSet to store elements and print them. For example, input the elements: “Apple”, “Mango”, and “Grapes”. Please state what the output would be when printing the HashSet with the three elements. Create a method treeSetExe to use Java TreeSet to store elements and print them. For example, input the elements: “Apple”, “Mango”, and “Grapes”. Please state what the output would be when printing the TreeSet with the three elements. Create a hashing function that takes the string, calculate the sum of the ASCII code of each character, and return (sum%tableSize) as the index. For example, hash(“ab”, 11) returns 8, because ‘a’ is 97 and ‘b’ is 98, which adds up to 195, and 195%11 returns 8.
A binary tree is balanced if every node in the tree is such that the heights of its left and right subtrees do not differ by more than one. Complete the pseudo-code method isBalanced which determines if a binary tree is balanced. The function returns a value of -1 if the tree is not balanced, otherwise it returns the height of the tree. Add comments to explain what your code segment is doing. The following definition of a node in the tree is used. class BinaryNode { int element; BinaryNode left; BinaryNode right; } Complete the method below: int isBalanced (BinaryNode t) { int leftCount=0; int rightCount=0; if (t == null) //empty tree, height is 0 return 0; if ((t.left== null) and (t.right== null) return 0; else { . . . . . . . . . } }
Note that you can only use recursion to solve Q1 and you cannot use any loop. You are free to add helper methods, but you are not allowed to change the method header.Question 1: Crazy seriesIn this session, you need to implement the crazy series method. In the crazy series, you will be given a starting number. Then, you need to times 2 for each number until the number is greater than 100. After the number is greater than 100, you need to divide 3 until we reach the number is less than 5. Note that the input number must be greater than 0, and you are not allowed to use loop here.For example,crazySeries(10) should return ArrayList [10.0, 20.0, 40.0, 80.0, 160.0, 53.333333333333336, 17.77777777777778, 5.9259259259259265, 1.9753086419753088]crazySeries(5) should return ArrayList [5.0, 10.0, 20.0, 40.0, 80.0, 160.0, 53.333333333333336, 17.77777777777778, 5.9259259259259265, 1.9753086419753088]crazySeries(1) should return ArrayList [1.0, 2.0, 4.0, 8.0, 16.0, 32.0, 64.0, 128.0,…
Solution in Java Implement a method removeWord() that takes two string parameters: sentence - the sentence you are to remove a word from. word - the word you are to remove from the sentence. Your method should take a string, sentence and remove word from it. It will return a new string without word in the sentence. Examples removeWord("One two three four", "two") → "One three four" ● removeWord("Bob has a kid", "kid") → "Bob has a" (Ctrl)
