import java.util.Scanner;

class  Test 
{  
    public static void main(String[] args)   
    {  
        Scanner sc = new Scanner(System.in); 


    int num=sc.nextInt(); 
    System.out.println("Enter a number (-1 to end):"+num);
    int result=0;
    int i=0;
    while(true) 
    { 
      int n=num%10;
      if(n==-1){
        break;
      }
      i++;
      System.out.println("Digit"+i+" = "+n);
      result=result*10+n;
      num=num/10; 


      if(num==0) 
      { 
        break; 
      } 
    }
    }
