Implement two methods (using iterative and recursive approaches) to check if a given input string is a palindrome or not. Example 1: Input: [”radar”] Output: [true] Example 2: Input: [”radio”] Output: [false] ˆIterative Approach: public static boolean palindrome_iterative (String str) { } ˆRecursive Approach: public static boolean palindrome_recursive (String str) { }

how to write a java program that determine if a string is a palidrome using a recursive method and a non-recursive method (ignore characters that are not letters). Then write a driver to test the two versions of the two methods. (A palindrome is a string that reads the same forward as well as backward. For example, “otto” and “never odd or even” are palindromes) (driver can be hard coded)

Complete the following program Multiply.java. This program uses recursion to multiply two numbers through repeated addition. The output should look exactly like what is pictured below. The code should be completed where it states "complete here"

int funcB(int); int funcA(int n) { if (n 4) { return n* funcA(n - 5); } else { return n- funcB(n - 1); int main() { cout << funcA(13); return 0; What is the output of this program? Please show our work.

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 }

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

public class Main {    public static void main(String[] args) {        System.out.println("Your factorial is: " + factorial(9));    }} public static int factorial(int number) {        if (number == 0) {        return 1;    }        return number * factorial(number -1);    }   i need help fixing this code involving recursion

Given a string str and number n, write a program in JavaScript that recursively appends a copy of string str n times and returns the resulting string.

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
