MUST BE IN JAVA AND USE RECURSION Write a recursive method that returns the number of all occurrences of a given word in all the files under a directory. Write a test program. Use the following header: public static long findInFile(File file, String word)
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...
Write a JAVA recursive method to calculate an exponent. Your method should have the following header. Note: you can write a second, helper method if you choose. (Example: if base = 2 and power = 4, your method should return 2 ^ 4 = 16.) public int calculateExponent(int base, int power)
Complete java program below. Complete non-recursive version nthFibonacciWithLoop() method. Complete recursive version nthFibonacciWithRecursion() method. public class Fibonacci { // Fib(N): N N = 0 or N = 1 // Fib(N-1) + Fib(N-2) N > 1 // For example, // Fib(0) = 0 // Fib(1) = 1 // Fib(2) = Fib(1) + Fib(0) = 1 + 0 = 1 // Fib(3) = Fib(2) + Fib(1) = Fib(2) + 1 = (Fib(1) + Fib(0)) + 1 = 1 + 0 + 1...
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 java to find GCD of two integers using Euclid's method. Integers can be positive or negative. public class Recursion { public static void main(String[] args) { Recursion r = new Recursion(); System.out.println(“The GCD of 24 and 54 is “+r.findGCD(24,54)); //6 } public int findGCD(int num1, int num2){ return -1; } }
In Java: Given the following binary tree class, write a recursive method called size() which will find the number of nodes in the subtree rooted at the current node: class myBinaryTree{ int myValue; myBinaryTree left; myBinaryTree right; myBinaryTree(int inValue) {myValue = inValue;} public int size(){ <CODE WRITTEN HERE> } }
