{
public static void main(String args[]) throws IOException
{
int n,r;
InputStreamReader read = new InputStreamReader(System.in);
BufferedReader in = new BufferedReader(read);
System.out.println("Enter a number");
n=Integer.parseInt(in.readLine());
do
{
r=n%10;
n=n/10;
System.out.println(r);
}
while(n!=0);
}
}
