Answer #1

   public static boolean isPalindrome(String s){
   if(s.length()==0 || s.length()==1)/* if size of string is 0 or 1 then is always palindrome*/
   return true;
   /* is first and last char of string is same
   then make a substring removing them and call again the sunstring*/
   else if(s.charAt(0)==s.charAt(s.length()-1))
return isPalindrome(s.substring(1,s.length()-1));  
   else
   /* if above of does not satisfied
   then it is not palindrome*/
   return false;
   }

    A palindrome is a word, phrase, or sequence that reads the same backward as forward, e.g., madam or nurses run. In this program, ask the user to input some text and print out whether or not that text is a palindrome. Create the Boolean method isPalindrome which determines if a String is a palindrome, which means it is the same forwards and backwards. It should return a boolean of whether or not it was a palindrome. Create the method reverse...

    palindrome is a string that reads the same both forward and backward. C++ For example, the string "madam" is a palindrome. Write a program that uses a recursive function to check whether a string is a palindrome. Your program must contain a value-returning recursive function that returns true if the string is a palindrome and false otherwise. Do not use any global variables; use the appropriate parameters.

    Complete the printPalindrome method in the provided Palindrome.java program. The printPalindrome method accepts a String as a parameter and prints whether the parameter String is a palindrome (i.e., reads the same forwards as it does backwards, for example, "abba" or "racecar"). Make the code case-insensitive, so that words like "Abba" and "Madam" will be considered palindromes. import java.util.*; /** * Determines if a user entered String is a palindrome, which means the String * is the same forward and reverse....

    Write a C Program that asks the user to input a string and then the user is prompted back whether the input string is a “Palindrome Word” or not. (A Palindrome Word reads the same backward or forward, eg. madam, racecar, etc.) Your program should contain a function that accepts the input string from the main function and returns a value indicating whether the input string is a Palindrome or not. Use Pointers to traverse the string.

    Write a function check palindrome, which takes a string x as argument and which returns True if x is a palindrome, and False otherwise. A palindrome is a word that reads the same backwards as forwards (like for example “racecar”). Your function should be recursive (i.e. call itself) and proceed as follows. 1. If x is a string of length 0 or 1 return True. 2. If the rst and the last letter of x are di erent, return False....
