public class Main {
	public static void main(String[] args) {
		Scanner input=new Scanner(System.in);
		input.useDelimiter("\\.");//英文句号
		StringBuffer str=new StringBuffer(input.next());
		int[] a=new int[str.length()];
		for(int i=0;i<str.length();i++) {
			a[i]=Integer.parseInt(String.valueOf(str.charAt(i)));
		}
		int count=0;
		int[] c=new int[10];
		for(int i=0;i<10;i++) {
