1. Write a recursive function that returns the sum of all even integers in a LinkedBinaryTree. Your function should take one parameter, root node. You may assume that the tree only contains integers. You may not call any methods from the LinkedBinaryTree class. Specifically, you should traverse the tree in your function def binary tree even sum (root): Returns the sum of al1 even integers in the binary tree 2....
JAVA - Write a recursive function that takes a linked list as input and returns all of the elements in the linked list. Input: 1, 2, 3, 4, 5 Output: (1+2+3+4+5)/5 = 3 What I have: public static int findMean (Node head, Node cur, int n){ int average = 0; if (head == null){ if(n == 0) return 0; } if (n > 0){ int sum = n + findMean(head, head.next, n -1); average = (sum)/n; } return average; }...
Write a recursive method in **pseudocode** that returns the number of 1’s in the binary representation of N. Use the fact that this equal to the number of 1’s in the representation of N/2, plus 1, if N is odd java pseudocode is best
Write a recursive function that compares two given binary trees. It returns 1 if the two trees are different, and it returns 0 otherwise. The function signature is: int treeDiff (node "a, node *b); Write a recursive function that counts how many nodes in a tree have a single child. The function signature is: int countoneChild(node "root);
Using Java: 1. Recursive Multiplication Write a recursive function that accepts two arguments into the parameters x and y. The function should return the value of x times y. Remember, multiplication can be performed as repeated addition as follows: 5×6=6+6+6+6+6 2. Recursive findings Write a recursive boolean method named reFinding. The method should search an array for a specified value, and return true if the value is found in the array, or false if the value is not found in...
1. Write a recursive function that computes the sum of all numbers from 1 to n, where n is given as parameter. Here is the method header: public static int sum (int n){...} 2. Write a recursive function that finds and returns the minimum value in an array, where the array and its size are given as parameters. Here is the method header: public static int minValue (int [] data, int size){...} 3. Write a recursive function that reverses the...
Q1. Write a recursive function in C++ void printNumberedChars(string str, int i=0) { ... } which prints each character of the given string str on a new line, with each line numbered 1, 2, 3, …. For example calling the function with printNumberedChars("hello"); should output the following: 1. h 2. e 3. l 4. l 5. o Q2. Write a recursive function in C++ int sumArray(const int* arr, unsigned int size) { ... } which takes an array of integers,...
Create a recursive method that takes as input the root Node of a tree and returns true if the N variable of each node within that tree has the correct value (i.e., all nodes are labeled with the proper size of the subtree they define), and false otherwise.

Q1. BST: 1. Write a method that takes an array A, as parameter (A contains the elements of a BST traversed in preorder) and returns the corresponding BST 2. Write a method to list the nodes on the path from the root to a given node in the BST. 3. Write a recursive method to check if two BSTs are same. 4. Write a non-recursive method to check if two BSTs are same 5. Write a...
1. Assume you have a Car class that declares two private instance variables, make and model. Write Java code that implements a two-parameter constructor that instantiates a Car object and initializes both of its instance variables. 2. Logically, the make and model attributes of each Car object should not change in the life of that object. a. Write Java code that declares constant make and model attributes that cannot be changed after they are initialized by a constructor. Configure your...
