Program
import java.util.Scanner; public class DivisibleBy11 { public static void main(String args[]) { Scanner sc = new Scanner(System.in); System.out.println("Enter a number :"); String num = sc.nextLine(); int digitSumEve = 0; int digitSumOdd = 0; for(int i = 0; i<num.length(); i++) { if(i%2 == 0) { digitSumEve = digitSumEve + num.charAt(i)-'0'; } else { digitSumOdd = digitSumOdd + num.charAt(i)-'0'; } } int res = digitSumOdd-digitSumEve; if(res % 11 == 0) { System.out.println("Given number is divisible by 11"); } else { System.out.println("Given number is not divisible by 11"); } } }
Output
