Check string is Palindrome
Recursive Technique public class RecursionPalindrome { public static void main ( String [] args) { String str = "madada" ; System . out .println( new RecursionPalindrome().recursivePalindrome( str , 0 , str .length()- 1 )); } public boolean recursivePalindrome ( String txt, int front, int back){ if (front==back) return true ; if (txt.charAt(front)!=txt.charAt(back)) return false ; if (front<back+ 1 ) return recursivePalindrome(txt,front+ 1 ,back- 1 ); return false ; } } Using Loop public class Palindrome { public boolean isPalindrome ( String str){ int l =str.length()- 1 ; for ( int i= 0 ;i<str.length()- 1 ;i++){ if (str.charAt(i)!=str.charAt( l -i)) return false ; } return true ; } public static void main ( String [] args) { System . out .println( new Palindrome().isPalindrome( "malayala...
