A positive (strictly greater than zero) integer is called round if it is of the form d00...0. In other words, a positive integer is round if all its digits except the leftmost (most significant) are equal to zero. In particular, all numbers from $1$ to $9$ (inclusive) are round.

For example, the following numbers are round: $4000$, $1$, $9$, $800$, $90$. The following numbers are not round: $110$, $707$, $222$, $1001$.

You are given a positive integer $n$ ($1 \le n \le 10^4$). Represent the number $n$ as a sum of round numbers using the minimum number of summands (addends). In other words, you need to represent the given number $n$ as a sum of the least number of terms, each of which is a round number.

The first line contains an integer $t$ ($1 \le t \le 10^4$) — the number of test cases in the input. Then $t$ test cases follow.

Each test case is a line containing an integer $n$ ($1 \le n \le 10^4$).

Print $t$ answers to the test cases. Each answer must begin with an integer $k$ — the minimum number of summands. Next, $k$ terms must follow, each of which is a round number, and their sum is $n$. The terms can be printed in any order. If there are several answers, print any of them.
