- 5- Write an efficient java method that computes and returns the height from node t in a btree of any degree. . Please write proper comments in your java code. Your java code should not read or print anything. Assume btree node is defined as follow: private class node{ int count, data(); node parent, link[]:} // end class node private int height(node t){Java - The node (80, 85, 90) is split. Enter each node's keys after the split, or "none" if the node doesn't exist.C++ A robot is initially located at position (0; 0) in a grid [?5; 5] [?5; 5]. The robot can move randomly in any of the directions: up, down, left, right. The robot can only move one step at a time. For each move, print the direction of the move and the current position of the robot. If the robot makes a circle, which means it moves back to the original place, print "Back to the origin!" to the console and stop the program. If it reaches the boundary of the grid, print \Hit the boundary!" to the console and stop the program. A successful run of your code may look like:Down (0,-1)Down (0,-2)Up (0,-1)Left (-1,-1)Left (-2,-1)Up (-2,0)Left (-3,0)Left (-4,0)Left (-5,0)Hit the boundary! or Left (-1,0)Down (-1,-1)Right (0,-1)Up (0,0)Back to the origin! About: This program is to give you practice using the control ow, the random number generator, and output formatting. You may use <iomanip> to format your output. You may NOT use #include "stdafx.h".

- Problem 1: Create a Java class RecursiveMethods.java and create the following methods inside: ALL THE METHODS NEED TO BE COMPLETED RECURSIVLY. NO LOOPS ALLOWED. oddEvenMatch Rec: the method takes an integer array as a parameter and returns a boolean. The method returns true if every odd index contains an odd integer AND every even index contains an even integer(0 is even). Otherwise it returns false. sumNRec: The method takes an integer array A and returns the sum of all integers in the parameter array. nDownToOne: Takes an integer n and prints out the numbers from n down to 1, each number on its own line. inputAndPrintReverse: Inputs integers from the user until the user enters 0, then prints the integers in reverse order. For this method, you may NOT use an array or any type of array structure, in other words, you may not use any structure to store the user input. After completing the methods, use the main method to test them. You can hard code the tests.write this code below as algorithim to determine the leaf node reclusively ? public static void printLeafNodes(TreeNode node) { // base case if (node == null) { return; } if (node.left == null && node.right == null) { System.out.printf("%d ", node.value); } printLeafNodes(node.left); printLeafNodes(node.right); }Complete this codeYou 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. /** * Decide if it is possible to divide the integers in a list 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. * For example, oddAndTen([5, 5, 3]) → true, * and oddAndTen([5, 5, 4]) → false. * @param list is a list of integers. * @return true iff there is one odd partition and the other multiple of 10. */public static boolean oddAndTen(List<Integer> list) { // call your recursive helper method return ...} private static boolean oddAndTenHelper(...) { // add any parameters // base case // recursive step}
