一行 一个数 n（1≤n≤10^6）

输出格式：

最少的数的个数，并给出一种方案。

题目描述

A number is called quasibinary if its decimal representation contains only digits 0 or 1. For example, numbers 0, 1, 101, 110011 — are quasibinary and numbers 2, 12, 900 are not.

You are given a positive integer $n$ . Represent it as a sum of minimum number of quasibinary numbers.

输入格式

The first line contains a single integer $n$ ( $1<=n<=10^{6}$ ).

输出格式

In the first line print a single integer $k$ — the minimum number of numbers in the representation of number $n$ as a sum of quasibinary numbers.

In the second line print $k$ numbers — the elements of the sum. All these numbers should be quasibinary according to the definition above, their sum should equal $n$ . Do not have to print the leading zeroes in the numbers. The order of numbers doesn't matter. If there are multiple possible representations, you are allowed to print any of them.
