Q3. Create two methods: one that will reverse the order of the digits in an integer and a second determines if a number is a palindrome (i.e. reads the same front to back) using the following method headers. // Method 1: Takes in an integer and reverses it, e.g., reverse(456) returns 654 public static int reverse(int number) // Method 2: Takes in an integer and returns true if it is a palindrome. Use the reverse method you just wrote to implement this method. public static boolean isPalindrome(int number) Create a test program that asks the user to input an integer and provides feedback on whether the integer is a palindrome or not. Hint: To find the reverse number, use one of the following approaches: Modify your numerical inputs to a string, then use a for loop to reverse the characters with string concatenation and the charAt() method. Retrieve individual digits and combine them in reverse order using the /and % operators, using ten as a divisor. Combine the digits with either mathematically or with string concatenation. Sample runs Enter a postive integer: 3456 3456 is not palindrome Enter a postive integer: 45654 45654 is palindrome

Financial Application:• Write a program that computes future investment value at a given interest rate for aspecified number of months and prints the report shown in the sample output. • Given the annual interest rate, the interest amount earned each month is computedusing the formula: Interest earned = investment amount * annual interest rate /1200 (=months * 100) • Write a method, computeFutureValue, which receives the investment amount, annualinterest rate and number of months as parameters and does the following: o Prints the interest amount earned each month and the new value of theinvestment (hint: use a loop). o Returns the total interest amount earned after the number of months specified bythe user. The main method will:o Ask the user for all input needed to call the computeFutureValue method.o Call computeFutureValueo Print the total interest amount earned by the investment at the end of thenumber of months entered by the user.

Python Programming ONLY PLEASE NO JAVA Use recursion to determine the number of digits in an integer n. Hint: If n is < 10, it has one digit. Otherwise, it has one more digit than n / 10. Write the method and then write a test program to test the method Your test program must: Ask the user for a number Print the number of digits in that number. (describe the numbers printed to the console) Use program headers and method header comments in your code.
import java.util.Scanner ; //This program enables the user enters 10 int between -100 and 100 //then a menu is presented to the user to choose an operation to be //performed on the entered numbers. //operations: add all numbers and display their total //display the average of the numbers //find and display all negative numbers //find and display odd numbers //display all numbers in reverse order //display all 5 multiples public class OPonArrays { public static void main (String [] main) { int SIZE = 10; int [] nums= new int [SIZE]; Scanner KB = new Scanner(System.in); // populate the array for(int i = 0; i < 10; i++) { System.out.println("please enter a number between -100 and 100"); nums[i] = KB.nextInt(); } //display all elments for(int i = 0; i < 10; i++) { System .out.println(nums[i]); } fix the error
Write a value returning method that accepts two integer values as arguments and returns the value that is the greater of the two. For example, if 6 and 10 are passed as arguments to the method, the method should return 10. Your program should firstly prompt the user to enter two integers, and display the value that is the greater of the two. using Java programming
