Write a recursive method in Java that displays a portion of a given array backward. Consider the last entry in the portion first.

Write and test a Java method minimum() that returns the minimum of an array of n integers.

Write a short recursive C++ program that will rearrange an array of int values so that all the even values appear before all the odd values.

Write a java method that receives a reference to an array of integers and then sorts only the non-perfect numbers. if a number is perfect then it must remain in its current location in the array. Notes: 1) You are not allowed to use the Arrays.sort() method or any other ready-made sorting method. 2) You can not define new arrays. Your sorting must be in-place. 3) A number if perfect if the some of its divisors is equal to the number itself. For example the number 6 is perfect because the sum of its divisors is 1+2+3 = 6 while 8 is not perfect because the sum of its divisors is 1+2+4 = 7 which is not equal to 8.

Write and test a Java/Python recursive method for finding the minimum element in an array, A, of n elements. What the running time? Hint: an array of size 1 would be the stop condition. The implementation is similar to linearSum method in lecture 5 examples. You can use the Math.min method for finding the minimum of two numbers.

In java if i have this pseudo code that tries to explain how a method will work using recursion how can i turn this into working java code

Write a static recursive method in Java called mRecursion that displays all of the permutations of the charactersin a string passed to the method as its argument. For example, the character sequence abc has thefollowing permutations: acb, bac, bca, cab, cba. Then Write a static method called getInput that get aninput string from the user and passed it to the mRecursion method written above in a method call.Please does so using what I already had //Get input from in to call recursive method //to display those char permutations public static String getInput ( ) { Scanner in = new Scanner(System.in); String combination = in.nextLine(); System.out.println("Enter string:); return stringComb; //Method to show permutations of a desired string// This only return 3 string combination for some reason static void myRecursion(String aString) { //isEmpty check if ( aString.length() == 0){...

Design and implement a program that implements Euclid’s algorithm for finding the greatest common divisor of two positive integers. The greatest common divisor is the largest integer that divides both values without producing a remainder. In a class called DivisorCalc, define a static method called gcd that accepts two integers, num1 and num2. Create a driver to test your implementation. The recursive algorithm is defined as follows:gcd (num1, num2) is num2 if num2 <= num1 and num2evenly divides num1gcd (num1, num2) is gcd(num2, num1) if num1 < num2gcd (num1, num2) is gcd(num2, num1%num2) otherwise
