Exercise-3: Write a recursive and iterative methods to convert a decimal number to its binary equivalent string. The iterative algorithm (in pseudo-code) for converting a decimal integer into a binary integer as follows: 1. If the integer is 0 or 1, its binary equivalent is 0 or 1. 2. If the integer is greater than or equal to 2 do the following: 3. Divide the integer by 2. 4. Separate the result into a quotient and remainder. 5. Divide the quotient again and repeat the process until the quotient is zero. 6. Write down all remainders in reverse order as a string. 7. This string is the binary equivalent of the given integer. // Recursive decimal to binary method public static String dec2binRecursive(int n) { if (n<2) return n+ " ". else return dec2binRecursive(n/2) + n%2; } a) Write the Complete program for above Recursive decimal to binary method Algorit b) Iterative decimal to binary method

Write a recursive method called reverseString() that takes in a string as a parameter and returns the string in reversed order. The main method is provided to read a string from the user and call the reverseString() method. Use Java. Ex: If the input of the program is: Hello the reverseString() method returns and the program outputs: Reverse of "Hello" is "olleH". Ex: If the input of the program is: Hello, world! the reverseString() method returns and the program outputs: Reverse of "Hello, world!" is "!dlrow ,olleH". Hint: Move the first character to the end of the returning string and pass the remaining sub-string to the next reverseString() method call.   import java.util.Scanner; public class LabProgram { /* TODO: Write recursive reverseString() method here. */public static void main(String[] args) {Scanner scnr = new Scanner(System.in);String input, result;input = scnr.nextLine();result = reverseString(input); System.out.printf("Reverse of \"%s\" is \"%s\".", input, result);}}

Given two integers start and end, where end is greater than start, write a recursive Java method that returns the sum of the integers from start through end, inclusive.

Write a short recursive Java method that determines if a string s is a palindrome, that is, it is equal to its reverse. Examples of palindromes include 'racecar' and 'mom'. Test the method by asking the user to provide string entries to be checked. Hint: Check the equality of the first and last characters and recur (but be careful to return the correct value for both odd and even-length strings).

Ex. 01 : Recursion About So far, we have learned that we can perform repetitive tasks using loops. However, another way is by creating methods that call themselves. This programming technique is called recursion and, a method that calls itself within it's own body is called a recursive method. One use of recursion is to perform repetitive tasks instead of using loops, since some problems seem to be solved more naturally with recursion than with loops. To solve a problem using recursion, it is broken down into sub-problems. Each sub-problem is similar to the original problem, but smaller in size. You can apply the same approach to each sub-problem to solve it recursively. All recursive methods use conditional tests to either 1. stop or 2. continue the recursion. Each recursive method has the following characteristics: 1. end/terminating case: One or more end cases to stop the recursion. 2. recursive case: reduces the problem in to smaller sub-problems, until it reaches (becomes) the end…

Use java and correctly indent code.

Given an input string, delete recursively all the duplicate adjacent characters and return a string where all those adjacent characters that are the same have been reduced to just a single character. Do not use any loops. Do not use any regular expressions and methods such as matches, split, replaceAlI. Test case 1: delDuplicate("aaabbc") "abc" Test case 2: delDuplicate("aaaaa") "a"
