Below image shows the output of the above longest palindrome java program. We can improve the above code by moving the palindrome and longest lengths check into a different function. However, I have left that part for you. :) Please let me know if there are any other better implementations ...

In this article, we have learned about palindrome in Java. Also, we discussed different Java programs that illustrate how to check if a given input is palindrome or not. The most straightforward way to achieve this is by using the built-in method of StringBuffer class named reverse().Amit...
A palindrome is a word, phrase, number, or other sequence of characters which reads the same backward as forward, such as madam. Write a java program to find the longest palindrome present in a given string. For example, in the string a
Using string buffer , import java.util.*; import java.lang.*; class Seventeen { public static void main(String args[]) { Scanner sc=new Scanner(System.in); String str=sc.next(); String reverse = new StringBuffer(str).reverse().toString(); ...
A palindrome is a symmetrical string, that is, a string read identically from left to right as well as from right to left. You are to write a program which, given a string, determines the minimal number of characters to be inserted into the string in order to obtain a palindrome. ...
Another method to check if a string is a palindrome or not is by using aforloop. Below are the steps to check if a string is a palindrome in JavaScript. functionpalindromeFn(string){conststringLength=string.length;for(leti=0;i<stringLength/2;i++){if(string[i]!==string[stringLength-1...
