Write a RECURSIVE method that receives a string as a parameter. The method will return true if the string received as a parameter is a palindrome and false if it is not.

The method must not have any loops!

In JAVA

Expert Solution

The answer to this question is as follows:

The code is as follows:

import java.util.*;
public class Palindrome
{
   static boolean isPal(String str,int start, int end)
   {

       if (start == end)
           return true;

       if ((str.charAt(start)) != (str.charAt(end)))
           return false;

       if (start < end + 1)
           return isPal(str, start + 1, end - 1);

return true;
}

   static boolean checkPalindrome(String str)
   {
       int len = str.length();
       if (len == 0)
           return true;

return isPal(str, 0, len - 1);
}

   public static void main(String args[])
   {
   //I am providing the input as the static
       String str = "madam";
       //If you want the input as the dynamic please comment above line and uncomment below two line
       //Scanner sc=new Scanner(System.in);
       //String str=sc.nextLine();
System.out.println(checkPalindrome(str));

   }
}

The input and output are provided in the screenshot below:

Write a RECURSIVE method that receives 2 strings as parameters. The method will return true if...

Write a RECURSIVE method that receives 2 strings as parameters. The method will return true if the 2nd string is a subsequence of the 1st string. If not, the method will return false. An empty string is a subsequence of every string. This is because all zero characters of the empty string will appear in the same relative order in any string This method must not contain any loops. In java

Write a RECURSIVE method that receives as a parameter an integer named n. The method will output n # of lines of stars. For example, the first line will have one star, the second line will have two stars, and so on. The line number n will have "n" number of ****** (stars) so if n is 3 it would print * ** *** The method must not have any loops!

Python program. Write a function called cleanLowerWord that receives a string as a parameter and returns a new string that is a copy of the parameter where all the lowercase letters are kept as such, uppercase letters are converted to lowercase, and everything else is deleted. For example, the function call cleanLowerWord("Hello, User 15!") should return the string "hellouser". For this, you can start by copying the following functions discussed in class into your file: # Checks if ch is...

Write recursive method to return true if a given array has element equal to employee emp, or returns false otherwise. Array can be empty or not. //PRECONDITION: Varible n denotes the number of occupied positions in the array and must be non-negative. Employee class has method getSalary() that returns employee's salary, // and it has method boolean equals(Employee emp) that accept an employee object and returns true if employee calling the equals method is equal as employee emp, and returns...

Write a static method called "evaluate" that takes a string as a parameter

In Java language Write a static method called "evaluate" that takes a string as a parameter. The string will contain a postfix expression, consisting only of integer operands and the arithmetic operators +, -, *, and / (representing addition, subtraction, multiplication, and division respectively). All operations should be performed as integer operations. You may assume that the input string contains a properly-formed postfix expression. The method should return the integer that the expression evaluates to. The method MUST use a stack...
