Problem: 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 ≤ n ≤ 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.

Input

The first line contains an integer t (1 ≤ t ≤ 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 ≤ n ≤ 10^4).

Output

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.

Solution (in PYTHON3):

Solution:
def read():
    n = input()
    return [input() for _ in range(int(n))]


def solve(number: str):
    n = len(number)
    if n == 1:
        return [number]

    acc = []
    while n > 1:
        d = 10 ** (n - 1)
        number = int(number)
        g = number // d
        number %= d
        acc.append(d * g)
        n = len(str(number))
        if 1 >= n and number:
            acc.append(number)
    return acc
