Consider a recursive method below. static void mysteryRecursion (String x) { if (x.length () < 1) { System.out.println(x); } else { System.out.println(x.charAt (0) + " " + x.charAt (x.length () - 1)); mysteryRecursion(x.substring(1, x.length() - 1)); What gets printed if I make the method call mysteryRecursion("helloworld");

Given a long string use recursion to traverse the string and replace every vowel (A,E,I,O,U) with an @ sign. You cannot change the method header. public String encodeVowels(String s){ // Your code here }

Java - Write an iterative method that calculates the SUM of all integers between 1 and a given integer N (input into the method). Write a corresponding recursive solution. (return answer, don’t print)

public class Main { static int findPosSum(int A[], int N) { if (N <= 0) return 0; { if(A[N-1]>0) return (findPosSum(A, N - 1) + A[N - 1]); else return findPosSum(A, N - 1); } } public static void main(String[] args) { int demo[] = { 11, -22, 33, -4, 25,12 }; System.out.println(findPosSum(demo, demo.length)); } } Consider the recursive function you wrote in the previous problem. Suppose the initial call to the function has an array of N elements, how many recursive calls will be made? How many statements are executed in each call? What is the total number of statements executed for all recursive calls? What is the big O for this function?

Write a Non tail recursion and a tail recursion method in Java with a test class that does the following: The factorial of a positive integer n —which we denote as n!—is the product of n and the factorial of n 1. The factorial of 0 is 1. Write two different recursive methods in Java that each return the factorial of n. Please and Thank you

The method is in fact faulty. Give a test input (String) that will make the method to fail -- i.e., it will throw an exception when it is executed with the input).

Consider the following recursive method: public int recursiveMethod (int n) if (n <= 0) return 0; else int smaller = n - 1; return recursiveMethod (smaller) + n (n - 1); What is the integer return of a call recursiveMethod (5)? 36 39 40 44 Next Page Previous Page

Consider the following recursive method: Public static int Fib(int a1, int a2, int n){ if(n == 1) return a1; else if (n == 2) return a2;else return Fib(a1, a2, n-1) + Fib(a1, a2, n-2);} Please draw the recursion trace for Fib(2,3,5)

In Java - Implementing Recursion to Provide a Product Using recursion, create a program that will allow a user to enter five numbers. The program will provide the product of all five numbers using recursive methods.

Write a recursive method oddSum that takes a positive odd integer n and returns the sum of odd integers from 1 to n.

solve q4 only please

Write a recursive Java method that takes a String as a parameter and returns true if the String is a palindrome. You may assume that the string only contains lower case characters (i.e. no numbers, spaces, punctuation, etc).
