You can write this reverse() function by using either for loop or by using Recursion. If you remember, I already shared the logic of reversing String in my earlier post, how to reverse String in Java using Iteration and Recursion. Here we will use the same logic to check if String is ...

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 implementat...
// Java code for checking string palindrome public class Main { //function to check whether string is Palindrome or not public static boolean isPalindrome(String str) { // Checking for null if (str == null) { throw new IllegalArgumentException("String is null."); } // length of the ...
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...
We will simply convert the number into string and then using reversed(string) predefined function in python ,we will check whether the reversed string is same as the number or not.Algorithm/StepsThe following are the algorithm/steps to print Palindrome numbers from the given Python list:...
Check if a Python String Is a Palindrome Using Recursion Another interesting approach to determine if a string is a palindrome involves using the recursion method. Recursion is a concept where a function calls itself, and in the context of checking palindromes, we approach the problem by comparing...
In this tutorial, you will learn how to write a java program check whether the given String is Palindrome or not. There are following three ways to check for palindrome string. 1) Using Stack 2) Using Queue 3) Using for/while loop Program 1: Palindrome c
Approach 3: using reversed() function In this approach, we will use the built-in reversed() function which returns an iterator that accesses the given sequence in the reverse order then we will add the characters in reverse order to a new string. Then we will compare the new string with ...
