Write a test programthat prompts the user to enter a string and displays its reversal.Write a recursive method called printReverse. The method shall take an array of char and will print the content in reverse order in the same line. The method shall use public and private method.
- Write a recursive method to print all the permutations of astring. For example, for the string abc, the permutation isabcacbbacbcacabcba public static void displayPermutation(String s)public static void displayPermutation(String s1, String s2)The first method simply invokes displayPermutation(" ", s). The secondmethod uses a loop to move a character from s2 to s1 and recursively invokesit with new s1 and s2. The base case is that s2 is empty and prints s1 to theconsole.Write a test program that prompts the user to enter a string and displays all itspermutations.taks 15.1 Follow these steps:● In a file called recursion.java, create:o a recursive function that reverses a stringo a recursive function that, given a number n, prints out the first nFibonacci numbers (Fibonacci numbers are a sequence whereeach number is the sum of the previous two - 0 1 1 2 3 5 8...)write a recursive method to schedule compatible activities that result in the maximum usage of the room.
- Phone numbers and PIN codes can be easier to remember when you find words that spell out the number on a standard phone pad. For example, instead of remembering the combination 5282, you can just think of JAVA. Make a recursive method that, given a number, yields all possible spellings (which may or may not be real words). This assignment needs a resource class and a driver class. The resource class and the driver class need to be in two different files. The resource class will contain all of the methods and the driver class only needs to call the methods. The driver class needs to have only 5 lines of code. The code needs to be written in Java. Please help me with exactly what I asked for help.Write a method named minimum value, which returns the smallest value in an array that is passed (in) as an argument. The method must use Recursion to find the smallest value. Demonstrate the method in a full program, which does not have to be too long regarding the entire code (i.e. program). Write (paste) the Java code in this word file (.docx) that is provided. (You can use additional pages if needed, and make sure your name is on every page in this word doc.) Use the following array to test the method: int[] series array = {-5, -10, +1999, +99, +100, +3, 0, +9, +300, -200, +1, -300} Make sure that the series array only tests for values, which are positive, given your recursive method.Rewrite the private static int recurseMax method without using Java API public class Recursion{ public static void main(String[] args){ // My tests (DO NOT MODIFY!) int[] a = {3,2,6,4,15,7,9,8,6}; p(recurseSum(a)); // Sum should be 60 p(recurseMax(a)); // Max should be 15 // End of tests! } // Recursive methods below here... public static int recurseSum(int[] a){ // TODO: This is the wrapper method. You must complete this AND implement helper method int total = recurseSum(a, a.length); return total; } private static int recurseSum(int[] a, int i){ if (i <= 0) return 0; return (recurseSum(a, i - 1) + a[i - 1]); } public static int recurseMax(int[] a){ int max = recurseMax(a, a.length); return max; } private static int recurseMax(int[] a, int i){ if(i == 1) return a[0]; return Math.max(a[i-1], recurseMax(a, i-1)); } //…
- java Write a recursive method largestDigitthat accepts an integer parameter and returns the largest digit value that appears in that integer. Your method should work for both positive and negative numbers. If a number contains only a single digit, that digit's value is by definition the largest. The following table shows several example calls: Call Value Returned largestDigit(14263203) 6 largestDigit(845) 8 largestDigit(52649) 9 largestDigit(3) 3 largestDigit(0) 0 largestDigit(-573026) 7 largestDigit(-2) 2 Obey the following restrictions in your solution: You may not use a String, Scanner, array, or any data structure (list, stack, map, etc.). Your method must be recursive and not use any loops (for, while, etc.). Your solution should run in no worse than O(N) time, where N is the number of digits in the number.Make a recursive method for factoring an integer n. First, find a factor f, then recursively factor n / f. This assignment needs a resource class and a driver class; these two classes will need to be in two separate files. The resource class will contain all of the methods and the driver class only needs to call the methods. The driver class needs to have only 5 lines of code. The code needs to be written in Java.The intName method in the "Problem Solving: Stepwise Refinement" section accepted arguments < 1,000. Using a recursive call, extend its range to 999,999. For example an input of 12,345 should return " twelve thousand three hundred forty five". Note that some number names may have extra spaces at the beginning or end. import java.util.Scanner; public class IntegerName { /** Turns a number into its English name. @param number a positive integer < 999,999 @return the name of the number (e.g. "two hundred seventy four") */ public static String intName(int number) { int part = number; // The part that still needs to be converted String name = ""; // The name of the number if (part >= 1000) { // Recursively call intName } if (part >= 100) { name = digitName(part / 100) + " hundred"; part = part % 100; } if (part >= 20) { name = name + " " + tensName(part); part = part % 10; } else if (part >= 10) { name = name + " " + teenName(part); part = 0; } if (part > 0) { name =…
