Given a string, write a Java function to check if it is palindrome or not. A string is said to be palindrome if reverse of the string is same as string. For example, “abba” is palindrome, but “abbc” is not palindrome. The problem here is solved using string reverse function. Examples:
Input : malayalam Output : Yes Input : Lazyroar Output : No
Java
// Java program to illustrate checking of a string // if its palindrome or not using reverse function import java.io.*;public class Palindrome { public static void checkPalindrome(String s) { // reverse the given String String reverse = new StringBuffer(s).reverse().toString(); // check whether the string is palindrome or not if (s.equals(reverse)) System.out.println("Yes"); else System.out.println("No"); } public static void main (String[] args) throws java.lang.Exception { checkPalindrome("malayalam"); checkPalindrome("Lazyroar"); } } |
Yes No
Time complexity: O(N), where N is length of given string.
Auxiliary Space: O(N), The extra space is used to store the reverse of the string.
