- 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.Write and implement a recursive version of the binary search algorithm. Also, write a version of the sequential search algorithm that can be applied to sorted lists. Add this operation to the class orderedArrayListType for array-based lists. Moreover, write a test program to test your algorithm.A consecutive sequence a list of numbers that are organized in increasing order with the next eleme. one bigger than the current. Write a non-recursive method "lengthConsec", which takes an IntNode myList as the parameter and returns the length of the consecutive sequence in myList. To simplify the implementation, you can assume that there is no more than one consecutive sequence in the list. For example, in the following linked list, the consecutive sequence begins at node "5" and ends at node "7", so lengthConsec (myList) should return 3 in this case. myList 8 13 4 public class IntNode { 12 private int m_data; private IntNode m_link; Consecutive sequence 6 7 28
- x <- bubblesort(sample(1:6, size=5, replace=T)) if (x[1]==x[5]){ hand <-"Yahtzee" } else if (x[1]==x[4] ] x[2]==x[5]) { hand <- "4ofKind" } } else { hand <-"Chance" } The above code lays this out for Yahtzee and 4 of a kind. Find statements that work for the rest and put this into a function called get hand , which returns what type of hand was rolled from a sorted roll of five dice. Make sets of rolls and test them to make sure they work. Note that above we use an else if, which allows us to test multiple conditions in an if-else statement.Lab 14.1 Beginning to build an Arrazlizt recursively In this sequence of problems we practice recursion by abandoning our reliance on iteration. We resolve to solve a sequence of problems without using while or for loops. Instead we will think recursively and look at the world through a different lens. Recursion is all about solving a large problem by using the solution to a similar smaller problem. The brilliant thing about recursion is that you can assume you already know how to solve the smaller problem. The goal is to demonstrate how the smaller solution relates to the larger problem at hand. For example, suppose you want to print all binary strings of length 3 and you already know how to print all binary strings of length 2. Here they are: 00 01 10 11 How can we solve the larger problem with a list of strings of length 2? Add a "0" or "1", right? So here is the solution to the larger problem: 00 + 0 = 000 01 + 0 = 010 10 + 0 = 100 11 +0 = 110 and 00 + 1 = 001 01 + 1 = 011 10 + 1 =…I am having trouble determining time complexity when it comes to finding the runtime of a method or function. I need to know what the runtime for the following methods are. Any further explanation would also be helpful. All of these methods are dealing with a binary search tree in java. 1. public String getAllValues() - return a String that contains the elementsof the tree in ascending order. All elements are separated by a space. 2. public int numberNodes() - return the total number of nodes in the tree. 3. public void insertList(int[] list) - insert all of the values from list intothe tree. Note: My Method just goes through an array calling working insert() method on all the values in the list[] array. 4. public int removeLessThan(int value) - this method removes all integers strictly less than value from the tree. It also returns the number of nodes itremoved. Note: In this method I first call a method to count nodes less than I call another method to recursively remove by…
- You are given an array-like data structure Listy which lacks a size method. It does, however, have an elementAt ( i) method that returns the element at index i in 0( 1) time. If i is beyond the bounds of the data structure, it returns -1. (For this reason, the data structure only supports positive integers.) Given a Listy which contains sorted, positive integers, find the index at which an element x occurs. If x occurs multiple times, you may return any index. Write code with explanationEdsgar Dijkstra is known for his work on programming languages. Hecame up with a neat problem that he called the Dutch National Flagproblem: given a list of strings, each of which is either 'red', 'green', or 'blue'(each is repeated several times in the list), rearrange the list so that thestrings are in the order of the Dutch national flag—all the 'red' stringsfirst, then all the 'green' strings, then all the 'blue' strings.Write a function called dutch_flag that takes a list and solves this problem.In Python 3 You can create a more interesting and realistic-looking tree by randomizing the angle the turtle turns. Rather than always using a 30 degree angle, select an angle between 15 and 45 degrees. randomizing how much the branches shrink each time you make a recursive call. Instead of always subtracting 15, try subtracting a random amount between 5 and 25. add color to the tree by making the large branches brown, and the small branches green. Choose a threshold value (or use the existing value 5) for the length of the trunk and set the color accordingly. Here is a simple version that creates a "dot" in the base case (for a leaf). Your program output does have to be similar. Thank You.
- Problem 3: In classroom, we implemented MyStack by including an ArrayList as private data field of the class (using composition). In this problem, we will use another way to implement the stack class. Define a new MyStack class that extends ArrayList. Draw the UML diagram for the classes and then implement MyStack. Write a test program that prompts the user to enter five strings and displays them in reverse order. (1) Your UML diagram: (3)boɔ ypleð The following code shows how one might implement a binary tree node: public class TreeNode ( public int data; public TreeNode left; public TreeNode right; public TreeNode(int d, TreeNode 1, TreeNode r) { data = d; left - 1; right = r; Suppose we have the following binary tree (with root being the node at the top): 7 The following method is an instance method in the TreeNode class. public int c() { int leftc = 0; if (left != null) { leftc - left.c (); int rightc - 0; if (right != nul1) { rightC = right.c(); return leftc + rightC + 1; Suppose root.c() is called. What is returned? Show memory diagrams and/or stack frames to explain what the recursive calls are.in this assignment i have to remove vowels from a string using a linked list. the linked list and link code is from a textbook and cannot be changed if the code alters the data structure. for some reason when i implement this code it gives me a logical error where the program only removes all instances of the first vowel in a string instead of moving through all vowels of the string and removing each one with all instances. i would appreciate if you could tell me the problem and solution in words and not in code.
