- Assume we have an IntBST class, which implements a binary search tree of integers. The field of the class is a Node variable called root that refers to the root element of the tree. 1) Write a recursive method for this class that computes and returns the sum of all integers less than the root element. Assume the tree is not empty and there is at least one element less than the root. 2) Write a recursive method that prints all of the leaves, and only the leaves, of a binary search tree. 3) Write a method, using recursion or a loop, that returns the smallest element in the tree.Assume we have an IntBST class, which implements a binary search tree of integers.

A trie is a data structure that permits efficient lookup of words in a dictionary (See figure). You may need to make two classes i.e. TrieNode and Trie. Your trie should support the following operations: i need one method in the tree prefix (trie) class which is THE ONE BELOW if you use helper method include it please: *****allWordsPrefix(String p) [return type String[] ] = this method returns all words whose prefix is ‘p’.***** the method should return and array of a given prefix, so for example if i pass the string ''TA'' into the allWordsPrefix(String p) it should return an array with all words starts with the given prefix. please do your best please i need this method allWordsPrefix(String p) [return type String[] ] i dont care about remove or insert method

For instance, if you added the Strings "one", "two", "three" in that order, code the SinglyLinkedList print() method to display "one two three". You can do this by recursively traversing the list, then displaying each item as you return from each activation record. For instance, data "one two" should be displayed as "two one".This needs to be in java. Thanks. You are to implement a binary search tree data structure. Your program should have a minimum of three classes (the node, the tree, and a driver). Your program should include the following abilities: Ability to add each name into a binary tree node – one at a time. Place each node into the tree following the general algorithm for binary tree insertion. (The minimum list of names to be used is on the next page). You may have the program load the names via a file read OR by hard code. In either case, you must enter the names 1 at a time using the “add” method you designed. Names will be read in/added in the EXACT order that they are listed. Ability to delete any name from the tree – one at a time. Ability to print out the tree in either order (alpha and reverse alpha) Ability to “search” the tree for a specific name. Return the number of probes (i.e. a look at a node). Each time you look at a node, it is considered a “probe”. Ability to “destroy”…
- In this task, a skip list data structure should be implemented. You can follow the followinginstructions:- Implement the class NodeSkipList with two components, namely key node and arrayof successors. You can also add a constructor, but you do not need to add anymethod.- In the class SkipList implement a constructor SkipList(long maxNodes). The parameter maxNodes determines the maximal number of nodes that can be added to askip list. Using this parameter we can determine the maximal height of a node, thatis, the maximal length of the array of successors. As the maximal height of a nodeit is usually taken the logarithm of the parameter. Further, it is useful to constructboth sentinels of maximal height.- In the class SkipList it is useful to write a method which simulates coin flip andreturns the number of all tosses until the first head comes up. This number representsthe height of a node to be inserted.- In the class SkipList implement the following methods:(i) insert, which accepts…Develop a class ResizingArrayQueueOfStrings that implements the queueabstraction with a fixed-size array, and then extend your implementation to use arrayresizing to remove the size restriction.Develop a class ResizingArrayQueueOfStrings that implements the queueabstraction with a fixed-size array, and then extend your implementation to use arrayresizing to remove the size restriction.1. A polynomial can be represented as a linked list, where each node called a polyNode contains the coefficient and the exponent of a term of the polynomial. For example, the polynomial 4x³ + 3x² - 5 would be represented as the linked list: 43 3 4x3 I 2 % 3x² Write a Polynomial class that has methods for creating a polynomial, reading and writing a polynomial, and adding a pair of polymomials. -50 -5x° In order to add 2 polynomials, traverse both lists. If a particular exponent value is present in either one, it should also be present in the resulting polynomial unless its coefficient is zero.
